Title: RHW Interchange Guide - Moved To A New Home! (See the Child Board Above)
Post by: Haljackey on January 23, 2009, 10:33:13 AM
Announcement: The RealHighway Interchange Guide has moved to a new board. You can find it here (http://sc4devotion.com/forums/index.php?board=419.0).

With the release of RHW 3.0 (and the latest release), there is virtually an infinite number of ways you can construct your highways and interchanges.  However, this is not a simple task, and takes quite a bit of getting used to.  Many folks have looked at several pictures of RHW interchanges and asked "whoa!  How'd you do that?" and have tried to construct something similar themselves, sometimes with much difficulty that eventually causes them to give up. 

This guide will show examples of various interchange types and will describe how they were made.  Feel free to ask questions after a guide has been posted if you are having difficulty.  I will attempt to show how to construct these interchanges as simple as possible, using only the necessary downloads.

If you'd like to submit your own guides to this thread, please send me a private message containing your guide in advance. Also be sure to follow the format set up in previous guides. Thanks!

All right, let's get started, shall we?

Section 1:  Diamond Interchanges
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2Fthumb%2F0%2F02%2FInterchange.svg%2F588px-Interchange.svg.png&hash=84ae69d9bdc93bbe7e81f588d9ae1ed842d75ee0)

To quote from Mightygoose's Compendium of Interchanges (http://sc4devotion.com/forums/index.php?topic=1433.msg133105#msg133105):

Quote"A very simple design involving two carriageways, usually perpendicular to each other however other angles are perfectly possible, of different grade (grade being quantity of traffic usually handled). The major grade carriageway in a diamond is referred to as the surface road, as it is customary that the road with higher usage has the least deviation from the horizontal. The minor grade carriageway is reflected to in this case as the street. The street may go either over or under the surface road but it will clearly undergo a greater elevation change if both routes intersect on level ground.

Diamonds are the simplest 4 ramp interchanges. They are often used in where there is a very large grade difference in the carriageways such as highways passing through inner boroughs of cities. However they scale up badly. At the ramp/street intersection, unless the street is very low grade, there must be lights. This slows down traffic, and if the street is high grade, cause congestion. Furthermore if the majority of traffic is using only one ramp of the interchange then efficient light timings are going to cause congestion on the street, especially if it is cross-carriageway turning (a left turn in the US or a right in the UK)."

Simply put, a diamond is a simple, space-saving low capacity interchange between a highway and a road.  All the road/highway interchanges Maxis included for the elevated and ground highways are diamonds and follow this concept. 

Now, I will show you how to make diamonds for the RHW!




Section 1.1: Standard Diamond Interchange

This is almost a direct copy of the RHW Readme file, showing how to make a RHW.  I will make a 4-lane RHW with a 1 tile median to keep things as simple as possible.

Place your starter pieces...

Voila!  You have a RHW!  Now lets make some diamond interchanges for it!




Standard RHW-type "A" diamond interchange.

From this part forward, the pictures will do most of the talking.  Note, this is just for reference, and your results can be different than mine!

Build your overpass.  For this example, I will use a simple road overpass using the NAM raised road pieces.  You can use proper land grading to create a much better looking, realistic result.

Get some RHW-2 action going now.  Drag your ramp setup at the ends of the overpass.

With those RHW-2s placed as visual examples, you now know where to plop your RHW type "A" ramps:

Connect the edge of the ramps up with the RHW-2s, and they should override to create the MIS ramps.

All right!  You have made your first diamond interchange!

The same setup can be applied for type "C" Ramps.  Just make sure you leave enough room next to the RHW for accel-decel lanes (RHW-6S).




Standard RHW-type "B" diamond interchange.

This setup will make the ramps intersect the RHW at a 45 degree angle, which will result in a smaller, better-looking diamond interchange.

Do all the steps used in the first guide up to here:

Now, instead of plopping the RHW type "A" ramps, plop the RHW type "B" ramps.

Now, connect the edge of the ramps up with the RHW-2s and you should get your MIS ramps working.

There you go!  Another RHW diamond interchange!




Standard "Space-Saving" diamond interchange.

Up to now, all the examples I showed were possible with RHW 2.0.  Well, RHW 3.0 is out now, allowing for even more possibilities!  Here is one example.

You'll need to construct the overpass a bit differently this time, putting the new RHW/MIS 4-way intersection piece on either side of the RHW.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi540.photobucket.com%2Falbums%2Fgg343%2FJackeyHal%2FTheInterchange-Dec2011232740601800x.jpg&hash=bdf26981fc8ff6d811ac573ba549f9d4142dd26c)

Use the ground to elevated MIS pieces on all four corners of the intersections you first built.

And then just use the type "A" RHW ramps to connect everything together.

Now, that's quite a space-saver eh?

The same setup can be applied for type "C" Ramps.  Just make sure you leave enough room next to the RHW for accel-decel lanes (RHW-6S).




Sunken Diamond Interchange

Two things you should get before we get started: hole-digging lots and a slope mod.

I am going to use both of them for this tutorial.  The end result will look similar to the sunken highway tutorial, but with the RHW!

Place your hole-digging lots.  (Hole diggers for sunken.)

Nice tutorial, Hal! There's actualy one diamond space saving interchange you forgot, and that's the variant that you elevate the RHW instead of the ramps.

By the way, to make my slopes smooth, I use another network (like El-rail) to do that. I think you used that method too.

Can't wait to see the next part, because you are never old enough to learn  ;)

Well, remember this is just a basic guide.  If you want to go diagonal, then apply the concepts I used, only diagonally.   ::)




Section 1.2:  Elevated Diamond Interchanges.

The El-RHW is a real beaut when it comes to making diamond interchanges.  In this guide, I will show you how to build 3 more diamond interchanges with the El-RHW, using the El-RHW type "A" ramp and ground-to elevated MIS transitions.




Getting the basic stuff out of the way

For this guide, I will construct a El-RHW with a 0 tile median.  This makes sense as it gives the appearance that the entire highway is one structure, and because the El-RHW can easily be used in dense urban areas, a place where having a multiple tile median is rarely seen.

Place your starter pieces...

Drag the RHW using the RHW tool...

(Optional) Delete the starter pieces to create a RHW without any overrides.

And drag the stable network over it.

Congrats!  You now have a El-RHW!




Standard El-RHW Diamond Interchange

This setup is probably the easiest and most common type of elevated diamond interchanges, and is quite a space saver!

Drag a road under your El-RHW:

Place 4 ground-to elevated MIS transition pieces on each corner:

Plop your El-RHW type "A" ramps.

Drag the MIS on the ground to intersect with the road and connect to the other side.

And you're done!  Pretty simple eh?  Looks great too!




Higher Capacity El-RHW Diamond Interchange

A downside to diamond interchanges is that they have a low capacity.  When space is an issue, diamond interchanges will be placed in dense cities, creating a lot of traffic problems if overused.  This setup will be better to use in those areas because it contains an extra lane at the intersection and traffic lights for better flow.

Because this is going to be higher capacity, lets put an avenue underneath instead of a road.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi267.photobucket.com%2Falbums%2Fii281%2Fhaljackey%2FClayMessa-Sep25021232919376800x600.jpg&hash=ff82cb05019497af189dcde88d0f48b920cb38dd)

Drag one-way roads on either side of the RHW to create intersections.  Continue to drag them for at least one tile on each side of the intersections.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi267.photobucket.com%2Falbums%2Fii281%2Fhaljackey%2FClayMessa-Oct1021232919399800x600.jpg&hash=ba223b36b8380c92519789dbad4f07816b29e585)

Place 4 ground-to elevated MIS transition pieces on each corner, just like we did in the last guide:

And again, plop your El-RHW type "A" ramps.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi267.photobucket.com%2Falbums%2Fii281%2Fhaljackey%2FClayMessa-Nov30021232919542800x600.jpg&hash=bedd91ec590393aec5d3bf8bed8c18ac67608743)

Now, drag the MIS on the ground to the one-way roads.  The ramp will widen to two lanes, allowing for dedicated right and left turn lanes and giving the appearance that it is of higher capacity.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi267.photobucket.com%2Falbums%2Fii281%2Fhaljackey%2FClayMessa-Dec7021232919566800x600.jpg&hash=701c20d738d0e411489c377dcc9d302f27ecfb7c)

All right!  This should work perfectly for any urban setting.




Now for something different

This guide is made for ultra-dense cities where interchanges need to consume as little room as possible.  It may not be the best looking interchange, but it will get the job done while conserving space.

Place a elevated highway/avenue interchange in the middle of the junction.  Then drag El-RHWs up to the elevated highway, leaving one tile vacant between the elevated highway and the El-RHW.
-You can also use the elevated highway/road interchange too.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi267.photobucket.com%2Falbums%2Fii281%2Fhaljackey%2FClayMessa-Feb14031232919783800x600.jpg&hash=c95976e641651616ac8aed23c109f6af653eaff6)

Now, cycle through the raised avenue puzzle pieces tab until you find the raised avenue-elevated highway transition puzzle piece.  Place them on either side of the elevated highway in the one tile you left vacant to create a working connection.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi267.photobucket.com%2Falbums%2Fii281%2Fhaljackey%2FClayMessa-Mar31031232919884800x600.jpg&hash=e64d087440b4c01c07c28416cdbfe9cb6decbd98)

And that's it!  The raised avenue-elevated highway transition puzzle piece can be used whenever you want to connect a El-RHW to a elevated highway.




I hope you find this guide useful!  The El-RHW is a fantastic addition, and its very useful for making interchanges!

Older slope mods didn't include RHW. There was a separate slope mod for RHW made by kt3. All my slope mods work with RHW. I choosen RHW smoothness (max slope change between neighboring tiles) and max slope identical as for avenue. Ground highway smoothness is the same, it's max slope is a bit less.
Please try use my slope mod (version Medium 315 or - maybe better - Smooth 212) and tell me if RHW parameters are good for your needs. I can modify them if you want.

Haljackey - great tutorial! Very clear and helpful.  :thumbsup:
Some people showed interchanges with inside exits (in the "Show us your interchanges" thread). Maybe you could show them in your tutorial?

Adam :thumbsup:

Edit: sorry, bones1 slope mod works with RHW (but it is very steep), JRJ BRF one doesn't.
Here is a comparation from my slope mod readme:

I knew there were actual slope mods that included RHW, I was just wondering if there was one included, maybe there should be, if that's possible (without interfering with other mods)

Excellent guide you've got here, Hal! It's made me think a little bit about the techniques I use to build my interchanges, and I think I might change a few things now...  ;)

JoeST:  Looks good!  I will give you guys full permission to post my guides on the Wiki.  There are still some spacing problems with it, and the images are still not hosted on the Wiki.  Since my free photobucket account can easily exceed its monthly bandwidth, it may be a good idea to host them on the Wiki.

Ennedi:  Very interesting.  I use the Bullet Train Slope Mod that APTX included with his amazing bullet train mod (BTM) for most of my slopes.  I think I am also using kt3's RHW slope mod as well, which is not as restrictive as the bullet train slope mod and better to use in hilly areas. 
-I don't know the specifications or angles APTX included in his bullet train slope mod, but I'd recommend you check it out.  There's a direct download to the mod on the Wiki.




As for left exit diamonds, you can take the concepts I applied and just use them for left exits instead of right exits.  Perhaps I will show a few examples using the left exits before I leave diamond interchanges and begin a new interchange type.

Personally, I don't like left exits at all.  Although quite useful, they are very unsafe compared to right exits since you are exiting/entering into the inside (passing) lane, which is usually the fastest lane of traffic opposed to the outside which is usually the slowest.  It can also catch drivers offguard since they are not the norm and may unintentionally use it or miss it.

Anyways, that's it for my little rant.  I will show a few left exit diamonds in the next guide.

Best,

Well the problem with that is I can only upload one image at a time, unlike uploading multiple images at once like photobucket and other free hosting sites offer.

Section 1.3:  Left Exit/Entrance Diamond Interchanges.

Made by request(s), I will show you how to make some diamond interchanges using the new left exit/entrance ramps included with RHW 3.0.




Getting the basic stuff out of the way

For this guide, I will construct a RHW with a 2 tile median.  You will need to have a RHW with a median of at least 2 tiles in order to get use left exit/entrance ramps for diamond interchanges.

Place your starter pieces...
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2Fimg0001.jpg&hash=8d54821f291a400f82a8d7c0e2143aa1dc94b6b2)

(Optional) Delete the starter pieces to create a RHW without any overrides.

And drag the stable network over it.

Ok, your RHW is now set up.




Standard RHW left exit/entrance diamond interchange

Again, I will use a road as an overpass this time.  Make sure you put two 4-way El-MIS/raised road intersections in the median tiles, and make sure they are facing the right direction!
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2Fimg0005.jpg&hash=b81381114a33c8551a5b62ab64e10cbb874da71d)

Plop 4 ground-to-elevated MIS transition pieces next to the intersections you made in the RHW's median.

...And then place the left RHW type "A" ramps next to the MIS ramps.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2Fimg0006.jpg&hash=1a6414ffb3180f17626f59839a41e51f744203b3)

And you're done.  That's an odd looking diamond, eh?




High Capacity RHW left exit/entrance diamond interchange

This higher capacity interchange will not take up any additional room than the standard RHW left exit/entrance diamond interchange, and will look more at home in urban areas.  Like the higher capacity El-RHW diamond interchange, it will include an additional lane at the intersection and add traffic lights.

I will use an avenue for this diamond.  Place a 4-way raised avenue intersection in the median of your RHW.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Dec13021233025887800x600.jpg&hash=a47bea3384c4acd5da1d3a19136961e1ce0d661d)

Now use the ground-to-raised avenue puzzle pieces inside the median like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Dec20021233025912800x600.jpg&hash=b4190448207ec6b1af3ac186c2243ec36e1ff993)

Place the left RHW type "A" ramps next to the avenues in the RHW's median.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2Fimg0007.jpg&hash=ca2dd7f553f1e96d8dce76449a54be1bba2d53a1)

Then all you have to do is drag the MIS coming from the ramp to the avenue to create a working connection.

And there you go.  Kind of a mini SPUI for those who know what I'm talking about.




After I made this guide, I decided to play around with my new interchange for a bit.  I ended up making this interesting creation:

This 8-ramp monster handles traffic traveling in all directions.  The new outer 4 ramps handle right turns while the original 4 left ramps handle left turns.  It is truly amazing what you can make with RHW 3.0, there's just so many possibilities! 

Anyways I hope you enjoyed this guide.  That will just about do it for diamond interchanges I think.

Title: Re: Haljackey's RHW Interchange Guide
Post by: Ennedi on January 27, 2009, 02:01:34 PM
Hal, I checked APTX Bullet Slope Mod.

- It's not a standalone mod, it is a part of the railway.dat file which reskins monorail ( and probably El Rail too, I'm not sure). The APTX mod includes Traffic Simulator too, I don't know if it is compatible with the current NAM version - but it is probably possible to use only a part of it (reskinning network and trains, but without simulator).

- This mod changes only Monorail placing parameters. So if you want to make a soft slope, you must use the monorail first. I checked it.

- How does it change the network shape?
  - Max Slope Along Network = 4; very low, the slope is very small.
  - Max Network Slope Change = 30; it says how much can change the angle between neighboring tiles. Very high, similar to Maxis, BRF JRJ and CSX parameters (in fact all slope mods but mine have this property high). It means that the network will be bend at slope ends. It is not much visible in APTX mod, because the Max Slope is low, so the slope change can't be higher than 4 in any case. But the bend is visible.
Comparing to my "Smooth" version (see the table in my previous message)
- Monorail - Max Slope Change = 1, Max Slope Along Network = 6 ( 1,5 x APTX)
- RHW Max Slope Change = 2, Max Slope Along Network = 10.

There is an important factor which we must take into account comparing these parameters:
- If the Max Slope Change is low, the network at both ends of the slope (top and bottom) will be rounded and it will look smooth - it is one of main features of my slope mods. But it increases a distance needed to cover a given height difference, because the network needs a few tiles before it reach the max angle.
This is a reason why earlier slope mods creators used so high value of the Max Slope Change - because it makes the needed distance smaller, even if the Max Slope is low. But the price are bends at top and bottom  ;D
However, if we have a small slope (as when we build multilevel transit networks, the typical height difference is 15 m) with my mod installed, the network most often doesn't reach the maximum slope value, the Max Slope Change parameter doesn't enable it.

For your information, I made also a "Diabolical" version of my slope mod (so called by Shadow Assassin who requested it and as he said he was very satisfied). Some parameters of this version:
- Monorail: Max Slope Change = 0,6, Max Slope = 4 (exactly as in APTX but more smooth)
- EL Rail: Max Slope Change = 0,8, Max Slope = 5
- RHW: Max Slope Change = 1,6, Max Slope = 8

I didn't release this version because I didn't know if anybody would be interested in it (I asked and haven't no answer). But maybe you can try it and maybe you would be able to use directly RHW to make soft slopes, without placing another network first?
If so, please download and check  :)
Attention: Your other networks will be very smooth too  ;D

Wow, that's terrific news Adam!

I will definitely check out the new mod you've attached, and I'm sure many, many others may be interested in downloading it too after the release of RHW 3.0.

I don't really understand the parameters you put in your post, but it was a very interesting read. 
-Glad to know you enjoyed APTX's bullet train slope mod!  I use that mod to replace my monorail network and use it for sloping (well that is before I installed your mod).

Anyways thanks again for taking interest in this guide!  Glad to hear you're enjoying it!

Hmm... it seems that the Photobucket account I used to make the first guide has exceeded its monthly bandwitdth.  Don't worry, I use multiple accounts, so not all guides are affected.

For the time being though, there's a way around this.  If you have the Firefox browser, simply right click the "bandwidth exceeded" image and select "view image".  The actual image should appear rather than the bandwidth meter.




Section Two:  Parclo Interchanges
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg340.imageshack.us%2Fimg340%2F7585%2Fparcloa2320x200.png&hash=f56fe257ba1716dc144466da3b9eec74bcba8cd1)     (https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg52.imageshack.us%2Fimg52%2F3342%2Fparcloa4320x200.png&hash=6ef39ecf83ed1eb99b81481f57f0e7b1fab6d3c8)

As many of you know, Parclo Interchanges are my preferred interchange type.  Growing up in Ontario, Canada, the place where the Parclo Interchange was invented, its easy to see why I have a certain affinity to them.  They are used everywhere, and are only compromised if there is not enough room to accommodate them.

The term Parclo means partial cloverleaf, which is essentially what this interchange type is.  It's pretty much a cloverleaf interchange, but with two of the loop ramps removed, eliminating any weaving altogether.  The empty space where the removed loop ramps should be allow room for long acceleration/deceleration lanes and can straighten and elongate the outer ramps, greatly improving flow and safety features. 

The award-winning Parclo interchange has been well received, and is now used all over the world.  Parclos are difficult to construct for a ground/elevated highway in SC4, but the RHW is able to take advantage of this great interchange type.  I will show you several parclo setups throughout this guide.




Section 2.1:  The Parclo A-2 interchange.

The parclo A-2 is a interchange type consisting of 4 ramps, and is ideal to use in both rural and suburban areas.  Loop ramps are used to connect the arterial road to the highway, and long, straight ramps connect the highway to the arterial road, allowing for a smooth deceleration in speed off the highway instead of breaking to use the loop ramps.
-The parclo A-2 is designed to be easily upgraded to a Parclo A-4, which I will explain in a future guide.




Since I used the RHW-4 for all the diamond interchange guides, I'll do something different and use the RHW-6C for this guide. 

Getting the basic stuff out of the way...

That's what a RHW-6C looks like.  Neat eh?




Parclo A-2 Interchange

First thing's first, construct your overpass:

And then extend the MIS ramps to loop around and intersect with the road:

Now place some more RHW-6C type "B" ramps to connect with the RHW-2s, changing them into the MIS.

...And there you go!  A parclo A-2 interchange!




Other combinations

Unlike diamonds, the parclo A-2 interchanges follow a standard design and thus are not as diverse.  The concept will remain the same for all variations.  However, I will show you some ways to diversify them, by changing the way they intersect with the road.

The easiest thing you can do is replace the last few tiles of the offramps with one-way roads before the intersection.  This will create an extra lane so exiting traffic now has right and left turning lanes.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi366.photobucket.com%2Falbums%2Foo101%2Fhaljackey3%2FTerraInternationalAirport-Jul220212.jpg&hash=91f415d1e6013dea95c5ea30d7143a85aaaa22c3)

You can also use the RHW-2/MIS splitter piece to make the ramps join together.

And you can also create turning lanes and traffic lights by replacing the last tile of the RHW-2 with a road.

Anyways, that will do it for the Parclo A-2.  There are many more parclo interchanges to come!

Again, I would like to thank you all for your continued support!   :thumbsup:

And now I present to you my favorite interchange to make in SC4...




Section 2.2:  The Parclo A-4 interchange.

The parclo A-4 is a interchange type consisting of 6 ramps, and is ideal to use in both urban and suburban areas.  Dedicated ramps are used to connect the arterial road to the highway for each direction, and long, straight ramps connect the highway to the arterial road, allowing for a smooth deceleration in speed off the highway instead of breaking to use the loop ramps.
-The parclo A-2 is designed to be easily upgraded to a Parclo A-4, which is done frequently in real life.

This interchange is among the safest designs in the world, and one of the most economical to construct.   Invented in the 1970s, this interchange type is still being constructed on new highways today all over the world.

This interchange also looks fantastic in SC4, and is easy to construct.  How easy?  You'll see as I show a few ways to make one in this guide.




Let's mix it up a bit.  The Parclo A-4 is designed for urban and subrban use, so lets build a massive RHW-10 with a one tile median to display it!

Getting the basic stuff out of the way...

Place your starter pieces...

That's the RHW-10.  What a beast!




Parclo A-4 Interchange

The Parclo A-4 follows a very similar construction process compared to the Parclo A-2, but with some minor extensions which make it larger, safer, and of higher capacity.

Firstly, lets start by constructing your overpass.

Then, like the Parclo A-2, add entering RHW-10 type "B" ramps at the edge of the overpass like so:

Then just loop the MIS to connect with the avenue to complete the loop ramps.

Next, its time to make the offramps.  Extend the RHW-2, following the loop ramps you just constructed.

There.  If you finished at this point, you'd have another complete Parclo A-2 interchange.  But we're not done yet, we gotta make it in to a Parclo A-4!

For the final two ramps, there are a number of locations where it can go.  Some perfer to place the entrance at/before the offramp intersections along the avenue, others want to save space and put it as close as possible.  I will show both examples in this guide.




Setup 1:  Standard

Extend the MIS leading from the offramp and angle it towards the highway like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Apr24031233437515800x600.jpg&hash=a8584b9965d11f21d0087372444a8f5f0aa4f12f)

Then just plop another two RHW-10 type "B" ramps to finish everything up!

Setup 2:  Space-Saver

-At the edge of the overpass, drag another pair of RHW-2s like so:

Then, add some more RHW-10 type "B" ramps at the edge.

That's a space-saving Parclo A-4!




Other Intersections

Here, I will show you some other intersection types you can make for the Parclo A-4.  There's really no guide to follow, just use your mind to create whatever you desire!

Using one-way roads to create signaled intersection as well as direct on-ramps to the RHW.

I'll end this post now for organizational purposes but I'm not done with the Parclo A-4.  The next part of this guide will show you how to make a tight Parclo A-4 interchange.  Its complicated, but is much smaller in size compared to this!

Continuing right onwards from the last post

Tight Parclo A-4 Interchange

Constructing the Parclo A-4 interchange smaller is possible, but the construction method is unlike anything I've displayed in this guide before.  That is why I have split this up into a separate post, but will still follow in the Parclo-A4 interchange guide for organizational purposes. 

We're going to start like this.  Place your avenue within 1 tile of the RHW-10, and plop a pair of RHW-10 type "A" ramps like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Oct28031233438068800x600.jpg&hash=05dea69a665a236a1b0807b697194c993d0eb957)

Then you are to immediately create a tight loop ramp exactly as displayed. 
-Do not curve the MIS until it has completely finished crossing the avenue or else you will not be able to construct an overpass.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Nov9031233438103800x600.jpg&hash=d7ce911374c899980dee331ebc931196df399e94)

Now, carefully construct your overpass.  Make sure your ave-over-MIS puzzle pieces match correctly or the interchange will not work.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Dec30031233438218800x600.jpg&hash=23b01268630bbf229cd4f2bf32e01da918e946b5)

With that done its now time to construct the offramps.  Just like outlined in the last post, construct a RHW-2 that follows the loop ramps you made.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Jan21041233438282800x600.jpg&hash=599c89c4bf864ca00ee2e3164b495b5b7f99591f)

Then place RHW-10 type "B" ramps at the edges.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Feb3041233438326800x600.jpg&hash=e656f06a63d4687919b354566bc03003d9514b71)

And connect everything up.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Feb10041233438359800x600.jpg&hash=78cd4664ebfd3cb8aa2476d74e008813f192e370)

All right, you now technically have a tight Parclo A-2 interchange.  Lets go and complete it.




As I already showed you two different ways to construct the final two ramps in the last post, I'll use the space-saver design only to keep this guide shorter in length.

At the edge of the overpass, of the existing onramps, construct two more RHW-10 type "B" ramps.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Mar7041233438427800x600.jpg&hash=83f6d9c5d162e1f6e738ef126d53a0cf5e8526af)

The last step involves simply dragging the MIS from the ramps to the avenue.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi447.photobucket.com%2Falbums%2Fqq193%2Fhaljackey2%2FClayMessa-Mar16041233438458800x600.jpg&hash=dd870b6e79749f6bee56ececee9bd102366932d1)

And there you have it!  A tight Parclo A-4 interchange!




Anyways, I hope this guide helps you out in one way or another.

All the best,

The El-RHW is included with the latest release of the RHW mod: RHW 3.0, the one I am using for this guide.  You need to cycle through the starter pieces tab until you find the El-RHW starter piece.  Check the readme for more information.

As for the pictures, the monthly bandwidth for the Photobucket account used for the first guide has been exceeded.  I'm assuming the pictures should be reset later on today so you can see them.
-For the time being though, there's a way around this.  If you have the Firefox browser, simply right click the "bandwidth exceeded" image and select "view image".  The actual image should appear rather than the bandwidth meter.

Hope this helps!

Well, as you can see I use multiple images for these guides, and photobucket allows you to upload them all at once.  It saves me a lot of time compared with Imageshack.

Hmm... Did you make the off-ramp a 1-way intersection?  (Either with a MIS or OWR.)  If you do this, cars entering the highway cannot turn around and must turn right to use the ramp because all there is is right ramps. 

Perhaps you could include a visual?  I don't mind you posting it in this guide as I link all the guides in the stickied post. 

...And today's the 11th.  Photobucket told me that the pictures that have exceeded in bandwidth should reset sometime today.  Let's hope so!

Sorry for the long delay, I've been busy with RL.

Lately, most of my time spent on the SC4 community has been at Simtropolis.  If you didn't already know, the site is currently under upgrades to make it faster, more reliable and page-flip bug free (something we all enjoy at SC4D  :thumbsup:!)
-Roadblocks have been hit with the upgrades, and its a tedious task to overcome them.

Besides, most of the guides here contain pictures that have exceeded their bandwidth.  The next installment should come when they reset.

The next guide will continue with my parclo updates, keeping the thread organized.  Once I finish with RHW/surface road interchanges I will then focus on RHW/RHW interchanges like the trumpet you requested.

For the time being, see this guide (http://sc4devotion.com/forums/index.php?topic=5049.0) which shows how to build a trumpet in great detail.

Doesn't the bandwidth counter reset at the beginning of the month? If so, then you've exceeded your bandwidth in the first half of the month, in fact, I think that you (well, we actually, since we look at them) have succeeded in doing this in the first quarter of the month. Really, you need a faster account.

TmiguelT, it may be a slope-related issue.  Sometimes, if you're on even a slight incline or have a slope mod installed, it won't quite let you make the connection with the RHW-2.  You can use a Road sometimes instead between the two--that tends to do the trick here on my end.

They are back now, and I am assuming they will always be up from this point forward.

I'm not using the bucket anymore due to these problems.  6 accounts and I still get that stupid exceeded thing.  The bulk uploader at Imageshack has been improved and you won't get these problems.

All right, I'm back into making guides now.  You won't have to worry about bandwidth problems either.

Sorry its been so long!  I hope this guide will make up for it! 




Section 2.4: Parclo A-4 Interchange with dual acceleration/deceleration ramps.

Now we're moving into realism.  One of the biggest things that sets the RHW apart from the ground/elevated highways of SC4 is the ability to make proper entrances and exits, something we had no control over with Maxis.  The ramps were painfully short and totally unrealistic, without any accel/decel space at all before it merges with the main carriageway.

RHW ramp type "C" corrects this issue, enabling you, the user, to make a new lane when a ramp enters the highway, extending it for realistic accel/decel lanes or adding a whole new lane altogether.

Going by real world standards, accel/decel lanes should be at least 100 meters long.  Some older routes that have not been reconstructed may have very little merge room similar to the Maxis highways, which can also compare to the merge room on the type "A" and "B" ramps of the RHW.  The Ontario Ministry of Transportation (MTO) suggests that these ramps should be 300 meters long, but some exceed 400 meters in length to increase roadway safety where there's ample room to do so.

Since a tile in SC4 is 16x16 meters, anything between 5-9 tiles should make for a good acceleration/deceleration ramp (not including room in puzzle pieces).  I'll take the average of the two numbers and make the accel/decel lanes 7 tiles long in this guide.




When you're making an interchange with accel/decel lanes, its pretty much a jigsaw puzzle.  You won't need to worry about starter pieces or dragging RHWs this time, you start by plopping two RHW ramp type "C" puzzle pieces.  I left a two tile gap between them for an avenue overpass as well as a 1 tile median for this guide.

Now you can start dragging the RHW from the puzzle pieces.  Don't worry about the ramps for now.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg23.imageshack.us%2Fimg23%2F9601%2Fterrainternationalairpot.png&hash=5134c281634b8f9049051f2a10cc94656461dfc5)

The next best thing to do is get your overpass up so you don't have to worry about it later.

Now its time to join your ramps with your avenue in a typical parclo style.  Start to construct your offramps as well by dragging a pair of RHW-2s from the avenue toward the RHW.  Place a pair of type "C" ramps at the terminus.
-You'll notice a textural glitch when you plop the ramp pieces.  This can easily be fixed by redrawing the network.

Now hook up your offramps with the type "C" piece to override the RHW-2 into a MIS ramp.  Drag the RHW tool over the deformed RHW-6 to change it back to a RHW-4.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg16.imageshack.us%2Fimg16%2F6784%2Fterrainternationalairpoo.png&hash=673f6d6387972d314ddaf09a7af9b9733ab89cdd)

Time for the last pair of ramps.  Start dragging a RHW-2 on the outside of the intersections.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg4.imageshack.us%2Fimg4%2F540%2Fterrainternationalairpos.png&hash=c94e19680c369a0584bf2f7bc77e5b8fbba190ba)

Get yourself prepared by plopping two more RHW type "C" ramps further out.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg4.imageshack.us%2Fimg4%2F7619%2Fterrainternationalairpoe.png&hash=63729b2530ef99cd8405d1d0f42422f1fa4aa576)

Now just hook everything up!  Plop a pair of RHW-6S to RHW-4 transitions just next to your new onramps for a proper transition.  It works out to be exactly 7 tiles long.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg18.imageshack.us%2Fimg18%2F8814%2Fterrainternationalairpoa.png&hash=dfa0e2c27f794dd918321fdb0af3e59d36705d92)

Plop similar transitions on the outsides of the interchanges as well.  I'd suggest 7 tiles long on these to match the length of your loop ramps to make it look more uniform.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg16.imageshack.us%2Fimg16%2F6346%2Fterrainternationalairpob.png&hash=0293cebcd9815d6409bbbc54459a4606648a71c1)

...And you're done!  Here's a look at the finished product zoomed out:

Like all RHW interchanges, you can further customize your creation.  Here are a couple examples.

Give your offramp a more realistic appearance by converting it to a one-way road when it comes out of the curve.  This will also establish a pair of lights on the intersections.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg22.imageshack.us%2Fimg22%2F4264%2Fterrainternationalairpo.png&hash=7a56a7713f17514b043b38c8bcfaf8c474d82aa8)

If you're looking to save space, move your outermost on-ramps to the inside of the intersection.  Although this isn't as realistic and will add to traffic congestion, its a good way to spare some extra tiles for something else.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg5.imageshack.us%2Fimg5%2F4264%2Fterrainternationalairpo.png&hash=8366454058c97adaf1448ca0f84d1a32ce0c8c43)

Ok, time for another one, I told ya I'd be quick!   ;)




Section 2.5: Parclo A-4 Interchange with single acceleration/deceleration ramps.

This guide will be similar to 2.4 (the last one), with a twist.  Instead of having two ramps feeding traffic to the highway, there will just be one.  You might think to yourself this may save some space, when it is actually more space consuming than the dual-ramp setting.  The advantage of this setup is to make entering traffic more organized and contained, as well as allowing for proper merge lengths, essential for creating these realistic interchanges.

Like the last guide, I will make the accel/decel lanes 7 tiles long in this guide (per lane).




This time round its best to make yourself a RHW beforehand so everything can fit perfectly in place.

Since this is an elementary step, I'll show how to make it once more, taken from the first guide.

(Optional) Delete the starter pieces to create a RHW without any overrides.

And drag the stable network over it.

Now that you have a RHW, its time to build the interchange.  Start like so.  Construct part of your overpass as well as the MIS splitters as displayed, at least 3 tiles away from the overpass.
-Make sure you select the RHW-4 splitter and not the RHW-2 splitter.  You'll have 2-way traffic if you do that which is not what we want here.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg6.imageshack.us%2Fimg6%2F7339%2Fterrainternationalairpor.png&hash=c078c2b67e1b21e2ecdedd30e82f6db54f4c759a)

Start by making your ramps first.  The example shown is the most compact you can build.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg8.imageshack.us%2Fimg8%2F9601%2Fterrainternationalairpot.png&hash=65c6fcf4ecab18123fefa352b10ab422d241f776)

With your ramps in place, its time to finish building the overpass.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg23.imageshack.us%2Fimg23%2F6813%2Fterrainternationalairpol.png&hash=2f64e5c195387714bd16067e780256aef477d89e)

Now start getting your off-ramps ready.  Drag a RHW-2 from the avenue until you reach the RHW as shown.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg10.imageshack.us%2Fimg10%2F4264%2Fterrainternationalairpo.png&hash=d6cb39c36391e0b557b41af8da4ecdfb90f3a450)

Plop a type "C" ramp on the RHW at the edge of the RHW-2.
-You'll see a flawed RHW-6S as a result of plopping the type "C" ramp.  This is known.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg6.imageshack.us%2Fimg6%2F4264%2Fterrainternationalairpo.png&hash=6747b3b60d353848a39c90dc1a5466fb9b4b884a)

Drag the stub from the ramp on your RHW-2 to establish an override.
-Also, redraw the highway from the offramp toward the overpass to restore it to a RHW-4.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg8.imageshack.us%2Fimg8%2F4264%2Fterrainternationalairpo.png&hash=e471006432cc07888118920bb63656d705c0d90f)




Once you reach this point, you might want to consider what you want to do with your off-ramp.  Do you want it to be higher capacity?  If so you can convert the MIS to a one-way road for the intersection.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg11.imageshack.us%2Fimg11%2F4264%2Fterrainternationalairpo.png&hash=809cdf381a28e72e61d03a684f1c050aba12134c)

Or even better, you can widen the ramp all-together.  In this image I replaced the type "C" ramp with a RHW-6S/dual RHW-4 transition and dragged the RHW up to the edge of the intersection, joining it with a one-way road.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg12.imageshack.us%2Fimg12%2F4264%2Fterrainternationalairpo.png&hash=e5538a474c6774144f77ac9e1128b664618cebdf)




Getting back to making the interchange, its time to join our on-ramp to the main highway.  There are actually two ways you can do this, and I will show both.

The first way you can do it is to plop a RHW-8/dual RHW-4 puzzle picece, making both onramp lanes reach the highway.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg8.imageshack.us%2Fimg8%2F189%2Fterrainternationalairpoc.png&hash=d479f4608803aa4e0d9f1e3d1ac50ef4dd9f22b5)

Here's a shot of the setup away from the centre of the interchange.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg27.imageshack.us%2Fimg27%2F6784%2Fterrainternationalairpoo.png&hash=977f8789620595101d8ea04b4c0c550b8ebfc943)

Then just evenly apply your RHW-8/6S and RHW-6S/RHW-4 transition along the roadway.  This example is shown with a 7 tile transition per lane.
-Do the same with your off-ramp, which just requires the RHW-6S/RHW-4 transition.  It's best to make it 7 tiles long as well to make it match the length of your other transitions.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg26.imageshack.us%2Fimg26%2F4264%2Fterrainternationalairpo.png&hash=ee7fe3bde5e44854c61e3ff19482be1979a0d3b3)




The second way you can do this is to allow the joining lanes transition to one before it reaches the highway.  This is a more realistic transition.

Drag your RHW-4 from the MIS splitter for 7 tiles, then apply the RHW-4/MIS transition.  Join the ramp to the highway using the RHW-6S/dual RHW-4 transition and drag for another 7 tiles.
-Don't forget to apply the RHW-6S/RHW-4 transition for your off-ramp!  It's best to make it 7 tiles long as well to make it match the length of your other transitions.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg21.imageshack.us%2Fimg21%2F4264%2Fterrainternationalairpo.png&hash=d88802dedccaf7137a8703f2c04de1ca5c8a5379)

...And you're done!  In this zoom out you will see the first on-ramp configuration used in the north and the second configuration in the south for comparison.

Here's a few modifications to the interchange you can make.

In this image, I moved the outermost on-ramp connections to the avenue to the other side of the intersections.  This will improve traffic flow and reduce congestion.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg13.imageshack.us%2Fimg13%2F4264%2Fterrainternationalairpo.png&hash=1298a3565f94476fda7e361f0564746c655a3067)

Here, I've extended the loop ramps by one tile, making them look more realistic.

Lastly, I used one-way roads to connect the outermost on-ramps to the avenue, which resembles an off-ramp.
-You could also convert this part of the avenue to a RHW-4 and use a type "A" ramp to connect the MIS.

These are fabulous interchanges!  I'm still a newbie at building transport networks.  I've finally decided to use RHW as my main city connectors instead of Avenues.  I have a problem here.   ()what()  I don't want to post all over the place but I posted on NAM problems once already.  Figured out to tab through the RHW starter piece to get to the MIS ramp and MIS elevated ramp pieces.  Still have a problem... how do I get things to slope up or down?  Here's a picture of my further attempts at this simple interchange.    &ops   :(

EDIT:  I found the on/off ramp for the MIS thanks to  carkid1998    .

One more question:  "And drag the stable network over it."  Does this mean using the basic RHW tool and dragging over just like I would with a RR station (rail tool) or Marrast's underpass pieces (rail & road tools)?

First, bulldoze the MIS starter pieces. Then plop the ground-to-elevated MIS transition (near the end of the transitions tabring) in their place. That's all you need to do.

Greenbelt -

You should not need the MIS or EMIS starter pieces at all - the on/off ramps will act as starters.

And as deathtopumpkins posted, you need the ground-elevated (or elevated-ground) MIS transition from the transitions tabring. It will say ON or OFF in various positions - OFF is for traffic going down and ON for traffic going up.

Haljackey, great tut, but the style you used, is better off in reverse where the traffic has ramps to exit each side on to the avenue, instead of having to wait at a light, because building the on and off system in reverse, the traffic does not have to be fighting to merge onto the MIS ramp just by making a left across the avenue to go onto the highway.

You would think the reverse would be better off, but in reality its not.  There's a simple explanation for that, in fact.  The arterial road (road/avenue) has a lower capacity than the highway (RHW).  Because of this, the extra ramps connect to the arterial road to make it more efficient, thus reducing traffic congestion.  Although all traffic exiting the highway must use the stoplight, this means it can be controlled at one point, making it more efficient.  In addition, these intersections are located away from the overpass allowing for more traffic movement.  (If a right turn ramp is made, then the lights just handle left turning traffic.)
-This design has won many awards and has been used commonly since the 1970s.  Its also an excellent alternative to a cloverleaf interchange when used with an arterial road.




Anyways, I do have something new to share.  Although this is technically "my" RHW interchange guide, that doesn't mean other people can't show their guides/creations here.  (I just have to approve them first! &scl()).  A Youtube user, who goes by the name of Asteconn, has created several RHW video tutorials on Youtube (you guessed it! :P).

If you want to take a look at his tutorials, here's a link to a playlist containing what he has made so far:

And a playlist video embed:

Oh, and by the way, he's British, so he drives on the left.  Right hand drivers, keep this in mind as he builds his junctions.  ;)

I hope you enjoy them!

The very least, that award winning design, would have signals on all sides coming to an avenue. In SC4, by default, it does not. This type of opportunity, I take advantage of and make custom signals, and signage for.

In the picture, it is too close to do this next thing, but just for future reference,
rather then first connecting the OWR from the avenue to the MIS, you can just connect the MIS directly to the avenue on an angle, instead of having traffic fight to merge before the ramp. Yes, I have been on this in reality, the old dual lanage on the ramp, merging on the ramp before merging onto the highway, and I still think it is stupid, and unsafe even then, especially with the slow semi trucks, because on a ramp, you need to speed up to merge, or you get hit, those guys slow you down, but that is besides the point. In situations other then this, MIS can make direct angular avenue connections, still without crossing the median, provided it hits both avenue tiles.

In reality, I don't know who made this idea, but I really came off an exit ramp where only the one side of the avenue going to the right had a stoplight and the other side on the left where it T's did not, and that made it harder, you had the green, but the side going to the left after did not even have a signal at all, and crossing was harder, because they saw the arrangement in SC4, and used it as a bad example.

Thank you so much Halijackey!  This is exactly what I was looking for!  This is one of the main reasons I did not like the RHW at first...the interchanges are very complicated.  But this makes it a lot easier.  Thanks again for all your hard work, and keep it up!

Hello Hal :)

You ought to update your playlist now that I have added the tutorials on T intersections :)

Good thread mind ^^

Like I said to you on youtube, but may as well reiterate here, is I'll be doing some 4 way interchanges soon: The 2 Level Roundabout, Halo and Cloverstack; probably in that order, because trying to condense building a cloverstack into 10 minutes is pretty hard! xD

All Right, let me get back to some of these replies:

Dreamcat:  I know, eh?  You're welcome!  The RHW can be a beast to tame when using it for the first time.  When I first used it, the RHW was a simple, straightforward mod.  Nowadays it can confuse any newbie because it is so complicated.  I hope things like this interchange guide help out!

Asteconn:  Hey, great to see you here!  Once again nice work with your turorials!
-The playlist has been updated to incorporate your new files.  I have also updated the sticky post and stuck your playlist and links in there.
-Good luck with the cloverstack!

@ Everyone else: thank you for your continued support!

More tutorials soon!  Perhaps a RHW to RHW interchange for once...  ;)

Section Three:  Trumpet Interchanges
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2Fthumb%2Fb%2Fb4%2FAs-tr%25C4%2585bka-prawa.svg%2F120px-As-tr%25C4%2585bka-prawa.svg.png&hash=6f489284e7931edd2cd3dfbcd495263b52faf58d)

This part of the guide will cover trumpet interchanges, a popular, realistic way to connect two RHWs together in a 3-way intersection.  Although they consume a good amount of space, trumpet interchanges are cheap to build and their design works particularly well with toll roads.

In right hand drive, the one loop in the trumpet interchange usually contains the ending highway, but this design can be mirrored to contain the starting highway.




Section 3.1: Simple Trumpet Interchange

This post will show you how to build a simple trumpet interchange, perfect for those who are new to the RHW or when space is a constraint.

So let's get started.  Construct your primary RHW (the one that is not starting/ending at the interchange).
-I am using the RHW-4 with a one tile median for this example.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg11.imageshack.us%2Fimg11%2F5152%2Fterrainternationalairpo.jpg&hash=52a10c98c52a7912f8b3a951b7d10d9426096bcf)

Now construct a pair of MIS overpasses like so:
-Make sure the yellow and white lines line up to ensure you have a working connection.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg109.imageshack.us%2Fimg109%2F5152%2Fterrainternationalairpo.jpg&hash=3489a8f746fb066ef8ae0d10507643bb3b0e7777)

Allright, on one end of the MIS overpasses, plop two MIS/RHW-4 splitter pieces, one for each direction.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg230.imageshack.us%2Fimg230%2F5152%2Fterrainternationalairpo.jpg&hash=b6269d998a777ba48b24a4e73a7c127a320d9acc)

Now, begin to drag your MIS stubs to create a design like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg189.imageshack.us%2Fimg189%2F5152%2Fterrainternationalairpo.jpg&hash=27ff055669dfd4afd7cfbb83942806cd263503b8)

Select RHW-4 ramp type "B", and plop four of them where the MIS meets the RHW-4.  It should look like this when finished:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg145.imageshack.us%2Fimg145%2F7319%2Fterrainternationalairpoi.jpg&hash=0fe8a1e16dd421524f0a1617982e7e6554f34583)

Lastly, extend your newly formed RHW network.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg96.imageshack.us%2Fimg96%2F5152%2Fterrainternationalairpo.jpg&hash=2a59a3e613773320d03e7fce961b2a6a69bc5963)

...And there you have it.  A trumpet interchange!




That also marks the first RHW-to-RHW interchange in this guide.

In the next guide, I will show you how to make a much more complex and detailed trumpet interchange.

Great job with the tutorial. I recently constructed a trumpet interchange similar to this to make a RHW spur. In my opinion, trumpet interchanges are one of the most useful interchanges you can make.

emgmod:  Thanks!  I too think trumpets look exceptionally good in SC4 when using the RHW mod.  Its without a doubt the best looking 3-way intersection.




Section 3.2: Complex Trumpet Interchange

Fasten your seatbelts and prepare yourself, for I am about to show you how to make a large, realistic trumpet interchange.
-Note: you will need the hole digging lots for this guide.

I am going to be as comprehensive as possible, but I don't want to flood the page with an exceptional amount of images.  Despite this, this will be the largest tutorial in the guide so far.  Just make sure you have enough experience using the RHW before following along.  If this is too much for you, then I recommend using the simple trumpet interchange guide in section 3.1 (http://sc4devotion.com/forums/index.php?topic=6843.msg299755#msg299755).

This interchange will have a higher capacity than the simple trumpet interchange because I am going to use RHW-4 for the ramps instead of the MIS ramps.  The advantage here is that by using RHW-4, smooth curves can be made.  Proper acceleration and deceleration ramps will also be constructed.




Let's begin.  Like the last guide, I am using a RHW-4 with a one tile median.
-Place your ground lifters from the hole digging lots at least one tile away from the highway.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg300.imageshack.us%2Fimg300%2F1442%2Fterrainternationalairpots.jpg&hash=99110cfce779b1368036334d721dc2a679c989ad)

Now drag road.  Start at the ground lifter, and drag away from the RHW.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg145.imageshack.us%2Fimg145%2F9152%2Fterrainternationalairpoob.jpg&hash=c5670323037ff50168af01e8e30be4f29e37c36b)

Demolish the roads and the ground lifters. 
-Now is also a good time to adjust the slope of the newly created hill.  I recommend using a slope mod to achieve this.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg262.imageshack.us%2Fimg262%2F3733%2Fterrainternationalairpok.jpg&hash=1821d767fb07e4846607ce130a82507f0b8780de)

Use road, street, or RHW stubs to create a 3x3 box at the top of your hills.
-At this point, I have also further sloped the sides of the hill to create a more realistic appearance.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg24.imageshack.us%2Fimg24%2F5743%2Fterrainternationalairpoc.jpg&hash=811d0083278b5bddd31c5ad3c1b30c2d14d03767)

Delete the two rows of stubs closet to the RHW and drag a road or street along the side of the RHW for two tiles.  This will also flatten the area so a smooth overpass can be made.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg691.imageshack.us%2Fimg691%2F2724%2Fterrainternationalairpou.jpg&hash=b41dd03f522df1ef18cbc27e92800f590fbdad4c)

Construct two RHW-4 overpasses using the Elevated RHW on-slope pieces.
-Make sure the yellow and white lines line up to ensure you have a working connection.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg13.imageshack.us%2Fimg13%2F3267%2Fterrainternationalairpoa.jpg&hash=16f4f2194940099f66e5d0c677b077aa9187b406)

Begin to drag your RHW from the overpasses.  Be sure to leave enough space for smooth curves, which will be added later.
-A good trick to ensure you left enough space is to plop it first, then demolish it.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg145.imageshack.us%2Fimg145%2F6079%2Fterrainternationalairpoe.jpg&hash=09f734ad4d61997ec0c7fe67bd26fde6f0f56be6)

Begin to drag your RHW from the overpasses in the other direction.  Place a pair of smooth inner RHW-4 curves where the slope ends.
-In this photo, I have turned on the grid to make it easier to see where the slope ends.  I use a very restrictive slope mod to create a low incline/decline angle.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg145.imageshack.us%2Fimg145%2F3253%2Fterrainternationalairpor.jpg&hash=9ee3dcd57ac650abd6c4f5d9ec796a4a943fe719)

Now to construct the ramps.  Use a pair RHW-6S to dual RHW-4 pieces at the edge of the inner curves.  Then drag the RHW-6S for a few tiles before using a RHW-6S to RHW-4 transition to start/end the lane.  I have used the RHW-6S for 7 tiles here.  Also now is a good time to drag your new RHWs from the curves and connect them to the main RHW in a similar fashion.
-You can also use the dual RHW-4 to RHW-8 pieces here if you want, depending on how high capacity you want your starting/ending highway to be.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg691.imageshack.us%2Fimg691%2F5152%2Fterrainternationalairpo.jpg&hash=ee0e80d6909ac901f6362a94b8a161734b8b897f)

Place a RHW-6S to RHW-4 transition at the edge of the overpass like so:
-As of RHW 3.2, the El-RHW-4 cannot cross networks wider than the RHW-4.  The extra length of the overpasses allow for a wider RHW to pass below when this is added in a future version.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg262.imageshack.us%2Fimg262%2F9284%2Fterrainternationalairpon.jpg&hash=cabd6fd8e1c1c4f4a40014b71a13cbfe0f84af73)

Allow about 7 tiles of RHW-6S before placing the RHW-6S to dual RHW-4 piece.  This will give a realistic look to the deceleration lane.  (Road stubs are used here only to show the 7 tiles)
-Again, the length of the lane can be whatever you wish, I just think 7 tiles is a good length to use for the purpose of this guide.  (Personally, I like to use 9 or more tiles.)
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg145.imageshack.us%2Fimg145%2F3733%2Fterrainternationalairpok.jpg&hash=444e91720e5192d951e05adc1301e644b4a3a041)

Start to drag out your RHW from the on-ramp.  This will form the loop of the trumpet.
-Also, if you have not done so yet, connect the outer ramps to the main RHW as seen in the top-right of this image.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg13.imageshack.us%2Fimg13%2F5152%2Fterrainternationalairpo.jpg&hash=d706216a0c1d8c50021e32eeca87c96ae9fa58ff)

Construct the loop, joining the overpass with the on-ramp.  Leave enough room for curves. 
-Also construct the outer ramp that follows the trumpet.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg300.imageshack.us%2Fimg300%2F9284%2Fterrainternationalairpon.jpg&hash=9801eeba0b6656d5576ecee26b4e116c2cf388a3)

Add in your smooth curves.  Outer curves go on the outer RHW, inner curves go on the inner RHW.  Makes sense, right?  :P
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg262.imageshack.us%2Fimg262%2F5152%2Fterrainternationalairpo.jpg&hash=c313cf0a743c68b61c3de1648050a3965d14ea5c)

Join your outer ramp with the main RHW.  Its pattern is exactly like the other ramps.  Allow 7 tiles or so for the off-ramp.  Place the last smooth curve here.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg300.imageshack.us%2Fimg300%2F1024%2Fterrainternationalairpoq.jpg&hash=ca243a958ddcffc889d6e90d1908342358e08538)

Now is a good time to smoothen the terrain if you so wish.  I would avoid using the level terrain tool as it can demolish all your hard work.  Drag a road/rail network to create a smoothed slope and then demolish it. 
-Again, this is why a slope mod comes in handy.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg13.imageshack.us%2Fimg13%2F1024%2Fterrainternationalairpoq.jpg&hash=69e191c1026edb71a953e9105faee9797d6ab4c6)

The finished result.  The bumps and steep slopes in the hills are now smoothed.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg145.imageshack.us%2Fimg145%2F8923%2Fterrainternationalairponf.jpg&hash=955f0c5732d6a4b1abaab631171c9491e513f23c)

...You're done!  This is a large interchange, so I'll have to zoom out to show the whole thing:

Congratulations!  You have now made a realistic trumpet interchange!  &apls &apls &apls




Additional Image:
Like almost every interchange, it can be further customized.  This image shows the loop ramp elongated to create a more circular curve.  However, this will increase the size of the interchange by a significant amount and is not at all needed.  Some players might find this appearance to look better than a straighter loop shown in this guide.

Impressive, but the trumpet part of the interchange can be a lot smaller if you drag the RHW side by side, as shown here:

Anyway, a good tutorial.

Oh and by the way, how about a tutorial how to construct a half cloverturbine? It looks very simmilar, except that the outer ramp is constructed wider than required for a trumpet interchange, so it later it can be extended to a full cloverturbine interchange:

Section 3.3: Compact, Complex Trumpet Interchange

This guide will show you how to make the trumpet interchange I displayed in Section 3.2 (http://sc4devotion.com/forums/index.php?topic=6843.msg300064#msg300064) more compact, while still maintaining its complexity and realistic look.  The major change here is that the loop ramp will be considerably more circular, reducing the footprint of the interchange.

I will also show some other applications to the interchange at the end of this guide.

To start, follow Section 3.2 (http://sc4devotion.com/forums/index.php?topic=6843.msg300064#msg300064) until you see this picture.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg691.imageshack.us%2Fimg691%2F5152%2Fterrainternationalairpo.jpg&hash=ee0e80d6909ac901f6362a94b8a161734b8b897f)




Now, unlike the last guide, I am going to construct the loop's on-ramp (a dual RHW-4 to RHW-6S transition) on the other side of the overpass.
-Don't worry about the graphical problems, just redraw the network to fix them.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fthermos.imageshack.us%2Fimg20%2F5152%2Fterrainternationalairpo.jpg&hash=16d85425f9bce9a2def5d5177c747b0330421c40)

On the other side of the overpass, begin to drag out your RHW in the form of a trumpet.  For the loop ramp, let the RHW-4 follow the mainline for about 7 tiles before curving it (this is where the RHW-6S to RHW-4 transition was in section 3.2.).  This will allow enough room to construct the loop ramp.
-As stated in the last guide, the widest RHW network the El-RHW can pass over is the RHW-4.  By drawing two RHW-4s side by side, a "loophole" can be found as you can connect them together on the other side to create a wider network (such as a RHW-6S or RHW-8.)
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg33.imageshack.us%2Fimg33%2F8294%2Fterrainternationalairpom.jpg&hash=a10cc0533356376d8bb01fb09469e3bbe7afcbb2)

Now plop in your smooth curves.  Remember inner curves go on the "inner" RHW, and outer curves go on the "outer" RHW.
-Watch your slopes as well.  The smooth curves are larger than the standard curves, so they require more room to create a smooth slope.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg697.imageshack.us%2Fimg697%2F5152%2Fterrainternationalairpo.jpg&hash=552f411e7d0b27bb466812a85663b580e14346e5)

Again, don't forget about your outer RHW's off-ramp.  Use a a dual RHW-4 to RHW-6S transition once again and a (inner) smooth curve to hook it up.  Extend the RHW-6S for about 7 tiles before using a RHW-6S to RHW-4 transition.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg43.imageshack.us%2Fimg43%2F5152%2Fterrainternationalairpo.jpg&hash=054fe5fdc5adfd8ccaaf0e249a0902ca7f18ae54)

And there you have it, a compact, yet realistic trumpet interchange!
-Don't forget to connect the loop ramp to the main RHW.  See the step above for instructions.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg697.imageshack.us%2Fimg697%2F1492%2Fterrainternationalairpoo.jpg&hash=cfd243c8b25382dd7dd90add5e696dc881437add)

The size of the interchange is considerably smaller than the trumpet shown in the last guide.




Other applications

These pictures will demonstrate some additional things you can do with this trumpet interchange and is not part of the guide above.  Again, this is optional.

Since we now have some extra room between the loop ramp and where the on-ramp is, this is a good spot to plop a RHW-4 to MIS transition.  This will concentrate all entering traffic from the loop into a single lane, making transitions smoother when the MIS meets the on-ramp.  Change the RHW-6S to RHW-4 ramp to a RHW-4 type "C" ramp. 
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg697.imageshack.us%2Fimg697%2F8294%2Fterrainternationalairpom.jpg&hash=5708a81bd05191c4fd6e787b575db671418af801)

The rest of the route can remain the same as shown in the guide.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg191.imageshack.us%2Fimg191%2F5152%2Fterrainternationalairpo.jpg&hash=96ba8d5b84651e8de93aac4bba2295aa509d5d43)

---------------------------------------------------------------------------------------------

You can also use dual RHW-4 to RHW-8 transitions in place of the dual RHW-4 to RHW-6S transitions.  This will create a wider RHW network able to handle higher traffic volumes.

Here's what the high-capacity interchange looks like when zoomed out:
-Note how I didn't use any transitions to narrow the RHW-8 to a RHW-4.

So after I made the interchange displayed in the last image, I decided to play around with it and add in some eyecandy.  Here's an example of what the interchange can look like when it is all "decked out":

Thanks Vince!

Well, the results from the poll say that the vast majority are quite happy to have an interchange guide, and it looks like my tutorials aren't too complicated to follow.

These results have encouraged me to continue with the guide, and maybe post some more complex tutorials in the future.

I'll keep the poll up for a bit longer.  Now its onto Cloverleaf interchanges.




Section Four:  Cloverleaf Interchanges
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2Fthumb%2F3%2F38%2FKnooppunt_klaverblad.png%2F150px-Knooppunt_klaverblad.png&hash=f8d7727f830cea07918f8d926bbd368f202ac1a2)

With Saint Patrick's Day coming up, I thought if I was ever going to post a four leaf clover (cloverleaf) interchange guide, now would be the time.

The cloverleaf section will be short because we can already make them with the Maxis Highways, and the fact that their design can cause weaving, something I don't like.  Additionally, they take up a monstrous amount of land using the RHW, even when you are going for a compact design.




Section 4.1: Simple Cloverleaf Interchange

The simple interchange I am going to show you resembles some of the older, outdated freeway designs, minus the weaving lanes.

Drag out your RHW.  For this example I am using a RHW-4 with a 0 tile median.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg718.imageshack.us%2Fimg718%2F7453%2Fnewcityfeb1100126834491.jpg&hash=ed129cd31a2c0ee1e08e290bbff8e471936df1a4)

Create your overpass.  Plop your RHW-4 to El-RHW-4 transitions right next to the underpassing highway.  Drag out your RHW from the overpass.
-You might want to make your overpass a bit longer if you are to widen your RHW or make weaving lanes in the future.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg46.imageshack.us%2Fimg46%2F6058%2Fnewcitymay2600126834524.jpg&hash=35ef216f7c0ff8f4915a9c63ad831f9bd53855a8)

Plop 8 RHW style "B" ramps at the edge of the under/overpass.  Make sure they all face outwards.
-This example is the most compact design.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg715.imageshack.us%2Fimg715%2F492%2Fnewcityjul2200126834540.jpg&hash=070ce27ea86f57b74caff122be6bd678a6d6c7ce)

Then use the MIS to connect them up to form the inner loops. 
-This is the most compact form.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg215.imageshack.us%2Fimg215%2F5955%2Fnewcityaug3100126834552.jpg&hash=c081a9f925f25747ac1fe4aa8e761f94b0d5ba67)

To give a more realistic appearance, try to elongate your loop ramps to make them more circular.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg717.imageshack.us%2Fimg717%2F2698%2Fnewcityoct4001268345652.jpg&hash=e5f8947f847cf9805cb432ab2e26422a51c03998)

To make the junction more uniform, you can also move your style "B" ramps on the underpassing RHW further away from the underpass so it lines up with the overpassing RHW's ramps.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg106.imageshack.us%2Fimg106%2F5337%2Fnewcitydec2300126834584.jpg&hash=6d42bdb6285eb725a15b2afcb0dc951d79357eb0)

...And you can also elongate the ramps here as well. 
-I'm going to continue the guide with this example because it has the most circular loop ramps.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg291.imageshack.us%2Fimg291%2F1364%2Fnewcityfeb2301126834600.jpg&hash=4c7ce487e7ad3533df494934c169fc0550e6a598)

Drag four diagonal segments of RHW-2 right next to your loop ramps like so.  This will serve as a guideline as to where to plop your outer ramps.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg59.imageshack.us%2Fimg59%2F5250%2Fnewcitymar1901126834609.jpg&hash=3ac61a8854cf34dd59f94e793fa259c61ff2689d)

Plop 8 more RHW style "B" ramps where the RHW-2 segments meet the RHW-4.  Part of the RHW-2 should now change into MIS.  Redraw your RHW-2 with the RHW tool and it should convert to MIS.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg46.imageshack.us%2Fimg46%2F4523%2Fnewcityjun1401126834643.jpg&hash=7d9adf032101cd909851a7e9e6a092dea2ed2469)




There you have it, a fully functional simple cloverleaf interchange!  Talk about a space hog eh?
-In fact, this junction is so large that the Maxis highway cloverleaf interchange nearly fits inside one of the loop ramps.  How's that for a size comparison?   :P

This also marks the first 4-way RHW-RHW tutorial in this guide! &dance I hope you found it helpful!

Hope you have a happy Saint Patrick's Day!

Thanks Everyone!

@Blue Lightning: You're getting ahead of me, what I have shown is just a simple cloverleaf interchange.  I will be showing more complicated junctions similar to your example in the future.
-If you look at section 3 (trumpet interchanges), I started off with a simple example before expanding to more complex guides.  Section 4 (cloverleafs) follow this pattern.

Section 4.2:  Complex Cloverleaf Interchange

Here I`ll be showing you how to make a more realistic, higher capacity cloverleaf interchange compared to the simple cloverleaf shown in section 4.1.  It shares many similarities with the junction Blue lightening (Vince) posted but has some distinct differences.

This page is getting flooded with images, so I have been making my images smaller to help minimize clutter and loading times.  Hopefully you can still clearly see what`s happening despite the size reduction.

To keep consistent with section 4.1, I will be using a RHW-4 with a 0 tile median for the main routes.

Note: Hole digging lots are required for this guide, and using a slope mod is strongly suggested.




Drag your RHW.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg651.imageshack.us%2Fimg651%2F7453%2Fnewcityfeb1100126834491.jpg&hash=3beb44da565b7de4516659812517941f7ae9553e)

Plop some ground lifters on either side of the RHW, at least two tiles away.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg106.imageshack.us%2Fimg106%2F4162%2Fnewcityoct1901126858762.jpg&hash=f568a62a6e464af8d00d5ef64afb162330dca87d)

Drag road from the ground lifters away from the RHW to create a slope.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg54.imageshack.us%2Fimg54%2F5092%2Fnewcitynov6011268587679.jpg&hash=1a44669f78f227f23c78e343f11231e6f771ce31)

Demolish the ground lifters and roads.  Use road stubs to even everything out.
-You`ll want a 4x1 segment of ground lifted, like so.  The road stubs are on the raised terrain.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg106.imageshack.us%2Fimg106%2F8728%2Fnewcitynov2001126858772.jpg&hash=cc78fbda1697601a283672938bec0f44f8533a9a)

Now drag your second RHW.  Create not only one on-slope overpass for the main route, but secondary overpasses as well.
-You`ll want a slope mod to create a smooth grade.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg54.imageshack.us%2Fimg54%2F5729%2Fnewcityjun2703126858944.jpg&hash=4ffada8d04d44a765dcd358acfc7c58444a2f2df)

Plop 4 RHW-4/MIS splitters next to the adjacent overpasses.  There should be about 4 tiles between this junction and the underpassing RHW.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg54.imageshack.us%2Fimg54%2F3159%2Fnewcitysep2703126858976.jpg&hash=7c453e2bafc983477d1c4aca34efc75b1df34159)

Complete your bridges. Drag RHW from one side to the other for all 4 overpasses.  Check to make sure the RHWs are facing the correct direction.  Drag MIS from the RHW-4/MIS splitters parallel to the RHW.
-Notice the weave lane?  This is an iconic part of cloverleaf interchanges. &blush Its also the reason designers hate it.  At least here we have the weave lanes separated from the main highway :P
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg54.imageshack.us%2Fimg54%2F6921%2Fnewcityoct5031268589809.jpg&hash=b240ccdc78b2d472ac6cc194c30f1824fa835e07)

Now its time to plop 4 RHW-4/MIS splitters next to the underpassing RHW.  They should be 3 tiles away from the overpass to keep the junction symmetrical.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg54.imageshack.us%2Fimg54%2F9098%2Fnewcityapr1041268590271.jpg&hash=0d28d78e14230e2c7c7c56c580725985039a0b94)

Drag your new RHW and MIS segments parallel to the main route.  Check to make sure the RHWs are facing the correct direction under the overpass.
-See how this thing is starting to come together?  ;)
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg31.imageshack.us%2Fimg31%2F8001%2Fnewcityapr1304126859032.jpg&hash=0140c045b33f876f3215d08b71aa7955d095778a)

Carefully construct your loop ramps.  For best slope results, drag from the overpassing RHW's junctions.
-Depending on how restrictive your slope mod is, the size of your loop ramps may differ.  My loops may not be as circular as yours because I use a very restrictive slope mod.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg352.imageshack.us%2Fimg352%2F229%2Fnewcityoct8041268590795.jpg&hash=15cdb174ab315e7ab462e6892b6cae4992bd2e4b)

Now its time to construct your outer ramps like so.  Drag from your MIS parallel to your RHWs as close to the loop ramps as possible, without draging over graded tiles.  (This will impact the slope of the loop ramps and your outer ramps will not be flat.)
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg502.imageshack.us%2Fimg502%2F9184%2Fclipboard01di.jpg&hash=c372afa004e0024e69de3a5dd0320c134f12ce20)

Do that for all 4 sides.  When you're done that your junction should look something like this:
-We're almost there!  It's huge, isn't it?  $%Grinno$%
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg31.imageshack.us%2Fimg31%2F8851%2Fnewcityfeb3051268591147.jpg&hash=0948f5fa16bd1f28389acf665388c4fa8e8a722e)

We need to connect those parallel MIS ramps with the main RHW now.  Select the RHW-4 type "C" ramp and plop 2 of them in each quadrant.
-Don't worry about the RHW glitches for now, it will be fixed in the next step.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg651.imageshack.us%2Fimg651%2F8652%2Fnewcityfeb1505126859120.jpg&hash=384ea686792f9dad1e17b359b5551ace67f1d4a2)

Plop your RHW-6S to RHW-4 transition a few tiles away from the junctions.  I recommend at least 7 tiles for realism.  Use the RHW tool to redraw any glitched sections now, as they should revert back to RHW-4.
-The road stubs are here show 7 tiles.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg651.imageshack.us%2Fimg651%2F1706%2Fnewcitymar1605126859130.jpg&hash=778d4f75f0aea84882945f94907451c690f3df2a)

...And you're done!  Here's the finished interchange.  What a beast!
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg638.imageshack.us%2Fimg638%2F443%2Fnewcityoct2605126859204.jpg&hash=c78436379d89cfacd9080c376b636f824f1473db)




Additional Images

You can also plop some RHW-4/MIS splitters where the two MIS sections meet.  This may look nice, but it isn't really needed because these ramps are already separated from the main highway and will make your junction even larger.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg58.imageshack.us%2Fimg58%2F6583%2Fnewcityapr5051268591385.jpg&hash=fd2576d7c60de66e1e47bc8f32dff2201c1ab1f9)

Shown here are two additional ways you can hook up your ramps to the main RHW. 
-The RHW heading east merges into one lane before merging onto the main RHW.
-The RHW heading west has separate lanes for each exit before breaking off the main RHW.
-The road stubs are here to show 7 tiles of merge space.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg54.imageshack.us%2Fimg54%2F3406%2Fnewcityaug6051268591749.jpg&hash=44feee96b5d45cbd7a7f0d38fcea1924e580bd29)




And there you have it, a complex cloverleaf interchange complete with weaving lanes! 

This design is slightly safer than typical cloverleaves because the weaving is taking place away from the main route.  However this design is more costly and takes up more space. 
-Nowadays cloverleaves are hardly ever built because of the danger weaving presents to drivers.  However in SC4, weaving doesn't make a difference to traffic capacity or speed, so its ok to use.  Still, I would suggest a design that doesn't contain any weaving that I may present later in future guides.

I hope this guide is useful!  If you have any questions or comments about this guide or others, feel free to post below.

Haljackey, great tutorial form you, as always.  :thumbsup:


Alas, I'm not sure that this high capacity cloverleaf can be done without access to RHW 4.0. In picture 9 you draw the parallel MIS lanes directly beside the slopes, which isn't possible yet with RHW 3.2. Also, I haven't succeeded with the 4x4 tiles center overpass until now, I always end up with this:

The last detail I spotted is the MIS split directly after the type C ramp in the 4th picture from the bottom.

The one part thats most interesting for me personally right now is the central crossover. Having seen this feature, it seems to me that the RHW network will be (again) much more stable in the next version. :satisfied:

That overpass problem should have been fixed by a patch released in the main RHW topic. And yes, Haljackey used several features that don't work with RHW 3.2. However, I don't see why you can't drag a MIS parallel to a RHW. I think it is a problem with your slope mod. Try grading the slope beforehand with the rail tool.

As Korot mentioned, you might be using RHW 3.2.  I suggest grabbing the subsequent patches (version 3.24 has them all, found HERE (http://sc4devotion.com/forums/index.php?topic=990.msg260203#msg260203)) that should fix your overpass bugs.

You should know that I don't use RHW 4.0 for any of these guides.  What's the point of giving a tutorial for something you can't make?  It would be useless, at least until RHW 4.0 came out.
-Also if I was using RHW 4.0 you would see a new texture set and features, none of which are found in this guide.

Like Korot, I have no idea what's preventing you from dragging a MIS parallel to your RHW.  It could be your slope mod.  Try dragging RHW instead of MIS at first and then replace it with MIS.

Haljackey used several features that don't work with RHW 3.2.

Again, I use RHW 3.24 for these guides.  No additional content is used other than hole digging lots and a slope mod.




EDIT: Oh, and I should mention if you're having problems drawing an overpass under several tiles of RHW, I suggest using a 1 or 2 tile median.  This should prevent the El-RHW to reverting into RHW-2.

Last time I tried, I couldn't drag a road/RHW/whatever through the starter stub, which you, apparently, can. And I'm also quite sure that I do have 3.24 installed, so I my guess would be that it is a feature of RHW 4.0, and that you have an old texture file lying around, somewhere.

Actually, all of the post-Version 3.2 fixes released on the RHW thread, including the Version 3.24 patch, are just path fixes.  The issue McDuell has run into is RUL-related, and all RUL fixes are distributed as part of the NAM Controller package (either via the NAM Core, Update or Essentials--all three of which on the LEX contain the same Controller build right now). 

I'm fairly certain that issue was one of the things that was fixed March 7, 2009, as part of the NAM Core update that came out concurrently with Version 3.2.  There's a possibility you may still have a controller with the Version 3.0 RULs (where the RULs still (mis)behave just like in the image) in it somewhere in your Plugins. 

I can confirm, however, that it's definitely fixed with Version 4.0 (though we're still working on color correction on some of the pieces):

I'm sorry for the upstir then, it was my fault. I could have sworn that I was using RHW 3.24 already, but after searching my plugin folder, it was nowhere to be found. So, zonk to me.  &mmm

About the parallel MIS, I used a wrong wording. What I meant was not that I'm unable to draw MIS parallel to the RHW, but drawing the MIS directly through the on-slope starter piece, as Korot mentioned.

Haljackey, you're right that I should know better, but based on my errors, I thought that this setup was impossible with the current RHW version. Please take my apologies for that.

P.S:     With the patch 3.24 I succeeded with the overpass as well as with the MIS split.
P.P.S:  Tarkus, if I remember correctly, i made this overpass right after RHW 3.0 has been coming out, so this is an old picture of the pre-3.2 era. This problem has indeed been resolved as I tried it out in the meantime without any issues.

Last time I tried, I couldn't drag a road/RHW/whatever through the starter stub, which you, apparently, can. And I'm also quite sure that I do have 3.24 installed, so I my guess would be that it is a feature of RHW 4.0, and that you have an old texture file lying around, somewhere.

I hope the post Alex (Tarkus) helped you out with your issue.  When in doubt, install the latest patches and controller files to make sure you don't have any conflicting files.  Adding an extra tile for a median or overpass connection can't hurt either because they will help to ensure a proper connection.

Remember, the guides I post here are just examples, you don't have to follow them directly.  The objective of these guides is to give you an understanding of RHW interchange construction through helpful text and images.

After looking at the readme for the RHW, I was about ready to say "forget this" and just give up on it. The readme says its a diffucult task. After going through 1 lesseon on a basic diamond exchange, my tune has changed to this is freakin' awesome. I don't know how many of you were involved in the creation of this project but I think you sall should be at major software companies making millions of dollars ( or whatever currency you have in your country.) I haven't seen how to add wide curves on the ramps yet, but I'm sure its here some where. Thanks a million!!!!!!!! &apls

Section Five:  Dumbbell Interchanges
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg716.imageshack.us%2Fimg716%2F1883%2Fclipboard01lq.jpg&hash=9a2064345fec2039d17a27f4fd379837f4482c64)

I wanted to devote a section of this guide for dumbbell interchanges.  It shares many similarities with diamond interchanges (which I showed in section 1) but instead of having intersections where the on/off ramps meet the road, a pair of roundabouts are used. 

Ireland uses dumbbells a lot, particularly on rural, lower capacity roads.  This design is both compact and efficient because traffic does not stop, and they look pretty good in SC4 too.

For all my dumbbell interchange examples, I will be using a road meeting a RHW-4 with a 0 tile median.  It is also important to note that the RHW should overpass the road, not vice versa, because the road expands to contain roundabouts not far from the centre of the interchange.  You will see this in the guides to come.

This will also be a good lead-in to roundabout interchanges, which will come in section 6.




Section 5.1: Basic Dumbbell Interchange

*Since we're already at page 6 of this thread, the starting picture will not be as basic as in earlier pages.  If you have trouble making the setup in the first picture, than I suggest looking at past guides for a detailed start-up.

Drag road.  Construct a RHW overpass over the road like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg146.imageshack.us%2Fimg146%2F6619%2Ftestsectoroct2402126894.jpg&hash=ca0f0fd3143c29ffadaed77f1375442b54138184)

Construct two one-way road roundabouts directly next to the RHW overpass (0 tile gap).
-Refer to your NAM Readme file if you do not know how to construct a one-way road roundabout.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg511.imageshack.us%2Fimg511%2F1923%2Ftestsectordec3002126894.jpg&hash=555892a9337ee1e81670f489301bbc18560cbfc3)

Plop 4 RHW-4 type "A wide" ramps at the edges of the overpass, facing toward the road/roundabouts:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg405.imageshack.us%2Fimg405%2F4512%2Ftestsectorfeb2031268946.jpg&hash=b37799907a5decf731dc2c8bfee3d28455d94879)

Using the RHW tool, drag MIS from the ramps to the edges of the roundabouts.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg682.imageshack.us%2Fimg682%2F2640%2Ftestsectorfeb1003126894.jpg&hash=c763c9756a36be2fe8e839ac36a5f0f65294c0e5)




Voila, you're done!  Pretty simple eh?  This marks the shortest tutorial in this guide!

...And I'll end it here.  If I made multiple guides per post, this page would get cluttered with images.  You don't want errors and long load times right?   :P

Section 5.2: Elevated Dumbbell Interchange

This small guide will show you how to build a dumbbell interchange using an El-RHW.  These work best in tight urban areas because they are small, free-flowing interchanges.

Start out by dragging your El-RHW over a road.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg233.imageshack.us%2Fimg233%2F3353%2Ftestsectormay8011268936.jpg&hash=255423324d23b5e28d866a8f7e8fb4214db2b0d6)

Build 2 one-way road roundabouts on either side of the overpass. 
-Unlike the last guide, they do not have to be 0 tiles away from the RHW, but it helps to keep them close to conserve space.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg202.imageshack.us%2Fimg202%2F8928%2Ftestsectorapr7021268945.jpg&hash=8da4c91f8d90a5a631bbe785885d279fc27a9898)

Drag 4 segments of RHW-2 from the roundabouts so that they meet parallel to the El-RHW like so.
-Do not curve the RHW-2 immediately before it intersects the roundabout.  Leave an extra tile or two so the network overrides to on/off ramps correctly.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg405.imageshack.us%2Fimg405%2F6715%2Ftestsectorapr2802126894.jpg&hash=7a7a1d5fb153199f28f2a7d6463306456304ae14)

Plop 4 ground/elevated MIS transitions where the RHW-2s end.  Make sure the white and yellow lines on the MIS align with the El-RHW to ensure a proper connection.
-The RHW-2s should now change into MIS.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg202.imageshack.us%2Fimg202%2F2559%2Ftestsectormay1902126894.jpg&hash=db7620db858c975e9164ccb3e9021243e31fb9dc)

Finally, plop 4 El-RHW type "A" ramps where the El-MIS begins to complete the interchange.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg233.imageshack.us%2Fimg233%2F9229%2Ftestsectorjul1802126894.jpg&hash=562cea18a8309b62c43603019fd0e359f9ec41c3)

That will be the next guide.  I'll be doing one for avenue, but it will not be using avenue roundabouts because their shape in reference to the grid of SC4 will give it an odd appearence.

I'll be using one-way roads to create an avenue dumbbell interchange with a shape similar to this:

That one is from the UAE.  Rotary's like that are also common in Massachusetts, USA, in the Cape Cod area.

Of course my example will have far fewer lanes.  I plan to split a RHW 4 into MISs and have one connect to a central RHW-4 which goes around in a circle.  It works best for light traffic intersections.

That one is not quite unlike the interchange near Joure, of the A6 and A7, in the Netherlands. Though at Joure, there is one lane less on the roundabout, and 3 of the approaching highways are RHW-4. The fourth road incoming is a normal road, since the interchange also doubles as Joure's access to the highway.

Section 5.4: Avenue Dumbbell/Raindrop Interchange

As mentioned in the above posts, there are a lot of difficulties to consider when building a dumbbell interchange for avenues.  The workaround: don't use roundabouts! 
-This guide will show you how to create such a junction.  It is also known as a raindrop interchange because in real life each side can look like a drop of water hanging from a faucet without the roundabouts.

I will show how to build this with a sunken route and on the ground level.




Fully Sunken Avenue Dumbbell Interchange

Here is step one.  Construct a sunken RHW and create two one-way road "on-slope" overpasses.  Be sure they are two tiles apart from one-another and everything is facing the right direction.
-See my earlier guides if you do not know how to create a trench for your RHW networks.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg209.imageshack.us%2Fimg209%2F4900%2Fcooperjan22021270753847.jpg&hash=78b35b66859db0fd366b18be0ba1bd9b6024a9e2)

Set up your avenue/surface street.  Create a bulge in the gap between your one-way roads by dragging them an additional tile apart on either side.
-Leave 1 tile of uncurved one-way road in the middle.  This is where your on/off ramps will connect.

Connect your one-way roads with your avenue.  Make sure you create a connection between your one-way roads as well.  There are two ways to do this.

I am going to use the second connection style for this guide because, while not as direct, it gives the interchange a distinct, well rounded shape.

Take a pause for a moment to make sure everything is connected in the right direction.  You've now completed the overpass and setup for the ramps.

Now its time to make the ramps.  Drag 4 sections of RHW-2 from the one tile of uncurved one-way road you left.

Create some slopes for your ramps.  Use road stubs and drag parallel sections of RHW-2s to make it as smooth as possible.

Sunken to ground Avenue Dumbbell Interchange

This time the only part of the RHW-4 needs to be sunken to create the overpasses for the one-way roads. 
-If this was elevated, the one-way road overpasses would be longer and would make the bulge further away from the RHW.  This would dramatically increase the size of the interchange.
-The setup for the overpass remains the same.

Drag your RHW-4 back up to ground level.
-Remember, this time it is the RHW mainline that is being graded, so the smoother the slope, the more realistic.

Here's a smoother way to slope your RHW, use a bullet train line to create the smooth grade for you.
-The slope mod for the bullet train is one of the smoothest in the game.  It is built into the Bullet Train Mod (BTM), which you can download HERE (http://www.simtropolis.com/stex/index.cfm?p=files&keyword=haljackey&view=all).

The result is an extremely smooth, realistic slope.  Just compare this to the one made with the RHW slope mod two steps ago!

Section Seven:  Diverging Diamond Interchanges (DDI)
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2Fthumb%2Fe%2Fe8%2FDivergerende_diamantaansluiting.png%2F120px-Divergerende_diamantaansluiting.png&hash=e7d347a80dfd1c23b141367ced8f0075b3e7a433)

I'm going to jump right from SPUI to the DDI as a lot of people seen to want to see how to build one. I might expand beyond basic SPUIs at a later time, and the same will go for the DDI.

Diverging diamonds are similar in appearance to simple diamonds, but they have a unique characteristic: they diverge. :P This is achieved by a major redesign of the intersections, allowing for all traffic movements to take place without crossing the other direction, except for the interchanging road itself. It intersects with the other direction and heads to the overpass in the opposite direction before heading back to the other side at the second intersection. (For right hand drive, from the right to the left to the right. For left hand drive, from the left to the right to the left.)

Sound complicated? Yes it does, but it's a rather simple interchange design when you break it down. I'll be showing you how to do it in a basic way, similar to how I built the Single-Point diamond interchange.




Section 7.1: Basic Diverging Diamond Interchange

Plop 2 diverging diamond pieces. These are found in the avenue/RHW puzzle pieces tab in the roads menu. The avenue stubs should be facing away. You need two tiles of empty space between them.
-I have the super gird turned on to show the two tile gap in greater detail.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg225.imageshack.us%2Fimg225%2F2136%2Fclipboard02sdv.jpg&hash=b353c45816480cba0d6c49bc51353d6d92ad3b92)

Drag one-way road between the two pieces. Be sure they are going in the direction the arrows in the puzzle pieces show (the opposite way).
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg132.imageshack.us%2Fimg132%2F8830%2Fwhocaresaug701127369521.jpg&hash=31732a2ce2ff303b28bef9b9e486d4e9257950c6)

Place 4 ground to elevated RHW-4 pieces next to the one-way roads in the gap.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg156.imageshack.us%2Fimg156%2F8743%2Fwhocaresoct101127369534.jpg&hash=5855368df30e99c6d2dad6ee7612c84235738b1b)

Drag your RHW and avenue.

Use 4 RHW-4 to MIS transitions at the ends of the diverging diamond pieces.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg265.imageshack.us%2Fimg265%2F6781%2Fgerpm.jpg&hash=5834d5687edd7b9e42368a3440ae026d60a00445)

Curve your 4 MISs and drag them toward your RHW. I would suggest while you're at it create RHW-4 type "B" ramps right now as well by dragging parallel then diagonally from the RHW-4.
-As an alternative you can always plop 4 RHW-4 type "B" ramps.
-This is how I did it:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg52.imageshack.us%2Fimg52%2F7338%2Fclipboard02sdf.jpg&hash=ea9c8b8a538bd9c180e7b708fb1540c16a01222e)

For more information on dragging ramps from your RHW-4 see this video:
http://www.youtube.com/v/SirdKOFtwzg
Link: http://www.youtube.com/watch?v=SirdKOFtwzg (http://www.youtube.com/watch?v=SirdKOFtwzg)

...And there you have it. A fully functional basic diverging diamond interchange. If there are texture problems with the MIS networks, simply click on them with the RHW toll and they should fix themselves.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg148.imageshack.us%2Fimg148%2F5287%2Fddvs.jpg&hash=b6395a7dac165c0e1cdda4f0b470603c6004bdf1)




Hopefully this should help out those who are having trouble building this interchange type. Diverging diamonds have better capacity than their diamond counterparts, due to the fact that all interchange movements do not need to cross the opposite traffic flow.

Yeah, I've seen it, and it is very well done. RHW 4.0 has a lot more connectivity than the previous versions which allows junctions like a basketweave configuration to be made more easily and more realistically.

It's on my "to-do list" for this guide. I plan to show how make one at some point, unless someone beats me to it. It would also be useful to show in the guide "How to make a Multi-RHW with RHW 4.0 (http://sc4devotion.com/forums/index.php?topic=5860.0)".

The name of this thread was changed from "Haljackey's RHW Interchange Guide" to just "RHW Interchange Guide" a while ago to allow others to post their guides here as well. I'll add whatever guides are posted to the sticky post. I would suggest you send me your guide as a PM so it can be polished before it's posted here, however.

First of all, thanks for this awesome guide!  Many of your interchanges on here have found their way into my cities.  ;D

I was reading the SPUI guide (thx, since I had no idea what to do with this piece) and had a thought...you mentioned that the MIS can't be directly connected to the avenue b/c it would create an intersection all the way across.  But what if you convert three tiles of the avenue to one-way's?  Then the MIS will only connect to one side.  It does take up a little more room, but it avoids the one-way stubs.

Thanks again for the great guide!

Hey, thanks a lot KL703! Glad you have found this guide useful!

As for the SPUI, you're right! Converting the avenue to a OWR would allow for direct MIS connections for the outer ramps.

An additional way to do it is to connect the MIS to a OWR-1 which is found in the Network Widening Mod (NWM) and then connect that to the avenue. However I won't show how to do that in this guide because I want these tutorials to use as little plugins as possible to make them easy to follow.

Sorry there hasn't been a new guide in a while. SC4 is crashing for me as soon as it starts &Thk/( . Hopefully I'll get the problem fixed soon.  ::)

You could, but their size and shape is relative to the standard diamond interchange. Capacity may be a little different along with traffic progression / cross road, but the rest of the characteristics would probably remain the same.

Well, I would assume the size is covered under the "Right of Way" category. The Parclo A-4 requires a much larger right of way than the diamond because of it's size. Other parclos leave corners free, but still take up a lot of room on the sides they do take up. Diverging Diamonds and SPUIs would have a similar right of way that a diamond has, whereas a cloverleaf would need a right of way similar to the parclo A-4.

Well, maybe you should read the Readme:

Quote
FLEXFly, or the Flexible Flyover system and a component of WAVERide, is an overridable puzzle piece. FLEXFly EMIS-1 (15m) Type A can be found at the end of the RHW Curves Ring, is 4x4, and is a 90 degree EMIS-1 (15M) curve piece, with the yellow line on the inside. FLEXFly can currently pass over the following networks:

MIS-1
RHW-2
RHW-4
RHW-6S (Main Lanes ONLY, do NOT draw the shoulder, it will draw itself)
RHW-6C
RHW-8C

Essentially it will NOT go over RHW-8 or RHW-10. (I find that to be a drawback... Maybe in the next version...)

Though I would agree that there should be a tutorial that features the FLEXFly piece, though I'm not sure if this is the thread for showing a tutorial on just the FLEXFly... Maybe an interchange that uses it... I know of one that might: The T-Bone interchange.

wyqtor I don't think they exist anywhere, but I can make one for you if you'd like.

Here's a basic rundown of building accel/decel lanes on a RHW-4.

1. Use the RHW-4 type "C" ramps to connect ramps to your highway. This gives you an additional lane when the ramp meets the mainline, turning it into a RHW-6S.

2. Drag the new RHW-6S for a few tiles. I'd say 7-9 tiles looks realistic for accel/decel lanes in SC4, but they can be as long or as short as you'd like.

3. When you're finished, plop a RHW-6S/RHW-4 transition piece where you want your accel-decel lanes to end.

It's as simple as that!

For added visual effects, you can use the RHW cosmetic pieces (the last RHW tab in the highways menu) to add dotted white lines for the accel/decel lanes as well as the transition.

If you need visuals to go along with this, let me know!




It's been a while since I updated this guide... I should get back to it lol. If anyone else wants to make RHW interchange guides, feel free to post them here! (I would recommend that you send me a PM with the guide so it can be polished before it's posted here.)

The final picture looks pretty, but I wonder whether it would match the traffic flow in many circumstances. Going straight ahead shares one turn-off, also with possible weaving issues, whereas turning left gets the two main lanes.

Nice guide riiga! The end result looks fantastic! I linked your post on the table of contents.
-One thing though, it should be section 8. Not sure why I said 10 lol. If you could change that in your post that would be great! (I would but I need moderator powers to do that.)

Glazert: This design is for very low capacity junctions. Not a single bridge/grade separation is used. Rotary designs vary from this to more roundabout-ish configurations. They are one of the most interesting, if not weirdest, junction types out there.

That wouldn't work with the current version of the NAM. You'll have to make the transition after/before the interchange, since there exist no inside diagonal ramps yet.

well i wanted to have ago at a diverging windmill and a diverging stack ( you don't list this but its incredible, it only requires two bridges (opposing carriageways of one of the highways) (four if you grade separate the weave) but i didnt realise that there was not a carriageway weave that doesnt have those ramps attached.

however since they are i managed to build a diverging cloverleaf..... can you tell me whats wrong with this picture :D

an avenue at grade lane weave (no ramps)
an RHW4 grade separated lane weave (one elevated)(no ramps)

Actually, they aren't yet.  I had been working on some awhile ago, but they kinda got waylaid because of trying to figure out the wackiness with pathing and the OneWayDir command on the RUL end.  I do plan to revisit them, however.

One question: why?

As Andreas said, a simple intersection would probably work better here. Besides Diverging Diamond pieces are one-way only, two-way connections don't work. In fact I don't even think two way roads can be supported by the diverging diamond design.

Still, very intriguing Goose. It boggles my mind.  %bur2$

@mightygoose: You're supposed to connect RHW-4 to the RHW-2 ends of the DDI pieces. If it were me, I'd use RHW-4 curves and fillers for that. Those are the only substitute for the currently unavailable OWR-2 WRC.

Your setup is kinda tricky to follow since I'm not LHD but, oddly enough, it makes sense to me. I guess the only way to make it more practical is to upscale it from using Ave-4 to using RHW-4... And eliminating the intersection lights in the process... Right now, I just don't know how to do that on paper, let alone, doing that in-game...

Looking good Goose! Yes I think it would be better if you used your compendium thread as this is more of a beginner's guide.

Actually, you can create B inside ramps. No puzzle piece exist, but by using the drag method in the sticky post video #1, you can actually create them. I am not sure if they are fully pathed and functional though as I've never made one. (I have a very anti-inside ramp attitude lol :P)

Interesting stuff here, Goosemeister! 

And to add to what Hal said, the draggable Inside Type B ramp on the RHW-4 is fully functional and pathed, but its RULs are rather unstable, which is why it's not on the "official" list of DRIs--it's kind of an "as-is" thing.  I've yet to work out a solution to stabilize it, as the way the default RHW-2 Type B Ramp overrides work conflict with the RHW-4 Type B Inside Ramp overrides.

Here is a high-standard clover-turbine (hybrid cloverleaf/turbine). You can make it into a guide if you want. Here are some important things to remember when making the guide:

  • If you look closely, you will see that the FlexFly graphics are a bit messed up. You could try placing them after the curved EMIS-MIS connectors are built (preferably use starterless ones)...
  • After the second curve in the loop ramp, use filler pieces between it and the curved transition (but don't delete the straight piece that is immediately adjacent to the transition)-otherwise you will get messed-up graphics
  • You might need to use the manual override for the ramps (see the RHW readme) for the loop ramps.

Section 10.1: Standard Windmill Interchange

In this guide I'm going to show you how to create a basic windmill type interchange.


First, put down 2 elevated Ramps and two starter pieces. Bulldoze the outer end of the starters.

Build two RHW->ERHW transitions as close to the existing ramps as possible.

Count 7 tiles of free space off the center and build 4 FlexFly A1 pieces. Leave the four builder tiles as reference points to make tile counting easier.

Complete each of the left turns with a curved MIS->EMIS transition, a MIS 45° wide right turn, and a RHW/MIS-splitter piece.

Connect all MIS parts. If you can't get the short diagonal parts to properly connect, just start from the other end and drag the MIS in the opposite direction. Build draggable A-ramps to connect the right turns to the main RHW.

Wow thanks McDuell! I usually avoid 4 way RHW interchanges because I don't have any in my arsenal that aren't colossal! Now, thanks to you I have a reasonably sized one to put almost anywhere in my cities. In fact, this whole thread is a great help to someone like me; I'm not a roadgeek but I like to put broad realism into my cities.

Keep up the great work everyone!

Stupendous guide McDuell! I love the compactness of the interchange. The tutorial is well thought out and the visuals compliment the text very well.

I have added your guide to the sticky post (table of contents). Just one thing I seemed to miss, your guide will be Section 10.1: Standard Windmill Interchange so if / when other guides are posted they can be properly organized into the table of contents. If you could edit that into your post that would be great! (Check other guides on the previous page for the formatting.)

Really nice end result. Having the ground-based ramps connect on the inside rather than outside substantially reduces the footprint of the interchange. Great use of curves too!

Section 8.2: Complex Rotary Interchange (1/2 grade-separated)
First, put down an avenue roundabout.

Now for the overpasses. Put 2 MIS>EMIS ON (not starterless) like this. They should be perpendicular to the 3rd tile after the roundabout, like this:

Demolish the 2nd, 3rd, and 4th tiles after the roundabout on the half of the RHW not covered by the transition, then place a MIS>EMIS OFF (not starterless) transition adjacent to the ones you made before. Then redraw your RHW. When it's done, it should look like this:

You've just made a 1/2 grade separated rotary interchange.
You can also subsitute the east-west RHW with an avenue, subsitute the MIS>EMIS transitions for RHW-4>ERHW-4 transitions, and use dual RHW-4 splitters instead of style-B or D ramps, and you have a left-exit/entrance rotary interchange.

Section 4.3 Partially Unraveled Cloverleaf Interchange (Partial Cloverfold)
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fjdenm8%2FRHW%2Fpartial_cloverfold_lights.png&hash=831435b9b82ec5bbbeae75724498a79c09a36cc2)

This is a SC4-tailored design I built from a need to have a weave-less Half Cloverleaf, and I pretty much just applied the idea to a standard cloverleaf. The main traits are that weaving is eliminated on the lower highway, and it's significantly more compact than a standard SC4 cloverleaf (We're using FlexFly, it tends to do that).
However, the upper deck still has basic cloverleaf designs intact, so weaving isn't completely eliminated. We have to wait for HEMIS for that  &mmm
Now, this interchange, due to the density of puzzle-pieces, means that if you stuff up even once you may have to demolish the entire interchange and start over.

To my knowledge, no interchanges of this type exist in RL.

This interchange requires RHW 4.1!

Anyway, how to build it.

First, take your crossing motorways. As you know, you will have to use RHW-4 for the overpass, but any RHW should work underneath.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fjdenm8%2FRHW%2FGuide%2FPartialCloverfold%2Fnamtest3-7_feb.__001294558491_export.jpg&hash=14a04e179fd62b150cbcd69bc67a6a99b21d1d1b)

Measure out two tiles on both sides (we're leaving space for the ramps) and then place the ERHW-4 Type A offramp so the ERHW-4 starter stub sits beside the second measured tile, like in the below picture.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fjdenm8%2FRHW%2FGuide%2FPartialCloverfold%2Fnamtest3-26_mar.__001294558607_export.jpg&hash=7882262a34aeb7c21bd8f751ebac648ebe3d4da6)

Next, we plop the RHW-4 to ERHW-4 transitions so that the ERHW-4 starters sit over the ERHW-4 starters of the Type-A exits.
Then we build the first looping ramps as shown below. (These can be on the same sides of the intersection if you want, I like it double mirrored) I dragged out seven tiles for deceleration for the loops.
Drag the MIS one tile past the overpass, then plop a starterless ON (for LHD) or OFF (for RHD) MIS to EMIS transition on the single tile stub.
Don't worry about the upper level, we don't need a starter stub there.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fjdenm8%2FRHW%2FGuide%2FPartialCloverfold%2Fnamtest3-25_apr.__001294558681_export.jpg&hash=ba85685502d8ae01f1a20dad9c26bc268239431e)

Now, we plop our A2 FlexFly loops (The one with the yellow line on the outside). This is why we don't need a starter stub on the upper level. Plop as shown in the pic, then drag MIS from the FlexFly ramps to connect them.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fjdenm8%2FRHW%2FGuide%2FPartialCloverfold%2Fnamtest3-14_may.__001294558733_export.jpg&hash=642e8335e281de903da99ff214c318dcb5f61eb6)

Your intersection should now look like this.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fjdenm8%2FRHW%2FGuide%2FPartialCloverfold%2Fnamtest3-24_may.__001294558758_export.jpg&hash=7894ced8d2772e3f7aac5ea736e053255247d3fa)


Next, we construct the other loop ramps. They're much the same, except they don't have a two-tile gap like the first ones, these have a one tile gap.
At the same time, build the MIS ramps on the ground level. These thread through the FlexFly on the tile beside the MIS to EMIS transition. Again, drag only one tile beyond the overpass. To connect to the motorway, you can use FAMIS or the Wide A-Type ramp for RHW-4. If you're not using RHW-4 underneath, the DRI Type-B ramp can sometimes work, but it's temperamental.

WARNING! The ERHW-4 likes to deconvert to RHW-2 at this point if you're dragging RHW-2 underneath to start with. Once you drag MIS through the new offramp, the overpass will pull itself back to ERHW-4. Until you drag MIS through, the overpass will not convert back to ERHW-4, so don't bother clicking all over the place.

Next, we plop the other type of starterless MIS to EMIS transitions, (OFF for LHD, ON for RHD) between the FlexFly piece and MIS on the new ramps.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fjdenm8%2FRHW%2FGuide%2FPartialCloverfold%2Fnamtest3-11_jul.__001294558891_export.jpg&hash=8d428be165ba520db4c1ed8fe99fbcd60fae2090)


Now, we've done the Looping ramps, the hard part, but now we need to connect the other four routes.
You can use FAMIS for this, but I used DRI Type-B ramps to save time.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.majhost.com%2Fgallery%2Fjdenm8%2FRHW%2FGuide%2FPartialCloverfold%2Fnamtest3-24_aug.__001294558990_export.jpg&hash=ee6c75b3276297ad0ec9adce4338b92bfe702321)

Because we used FlexFly for the loops, you can be creative with the connections. By making the loops a tile wider, you can even fit the wide MIS curve puzzle piece in there!

Hope this helps guys. It's an unusual and slightly overweight bunny, but it looks very good when done and half of the weaving of a regular Cloverleaf is gone.

I once thought of an interchange of a design like this once, and I referred to it as a "Collapsed Cloverleaf," seeing how the outer ramps are collapsed INTO the inner loops itself. Cloverfold sounds more fitting, though. The way I see it, It's still a type of Cloverleaf, only the shrink-wrapping of the outer ramps has been taken to a new extreme.

Section 8.2: Complex Rotary Interchange (1/2 grade-separated)

It looks like a good start, but I think this is too simplistic to list it as a "complex" rotary interchange and as an additional tutorial to this guide. It's simply a avenue roundabout connected to RHW-4 on four sides with a pair of elevated MIS ramps running parallel on one of the corridors. The fact that this is only partial (only one direction is overpassed) makes me question the practicalness of this guide.

Sorry if this sounds a bit harsh, but In the future, please send me a PM of your guide in advance so we can steamroll all the bumps. That way the final result can be polished and accurate. (Take McDuell's guide on the last page as an example.)

I really want to include this guide in the table of contents but there a couple things that affect its qualification as a proper tutorial.
-You're using lights and medians. The guide is supposed to be as basic as possible using the most minimal downloads (NAM, RHW and and anything else needed).
-What's with the concrete road deck for the elevated portion? Looks like your RHW version is not the current one or you have a cosmetic mod. Please try to keep it simple.

Please send me a PM prior to posting your guide here in the future. That way we can polish it before it is published.

Actually, that's a feature of the Alpha Builds for RHW Version 4.2--concrete textures on the elevated networks.  It's uncertain whether or not that will be in the actual mod itself once we get around to releasing it, or if it will be a separate addon.

I'll re-do it with the current RHW (or as close to as possible) and without Xylo's T21 mod.

8.2. Standard Roundabout Interchange

Roundabout interchanges are often used when there's is not much room (speaking in terms of space and budget). Roundabout interchanges are quite common in the UK and in continental Europe it's not an uncommon interchange type. The downside is however that these interchanges get quickly congested, but still it does handle traffic better than an at-grade intersection.

Today we create a Standard Roundabout Interchange (or technically speaking, a Dual-level Roundabout/Rotary Interchange), where one freeway continues, while the other intersects with a roundabout. This will require at least RHW v3.2, although I'm using RHW v.4.1 here.

1.  First we construct two RHW's:

2.  As you can see, I put some 1x1 road tiles around the RHW, which are marking an area of 12x12 tiles. This area will be demolished:

3. Then lay at the ends of the RHW some OWR stretching four tiles

4. Connect the ends of the OWR. Make sure the roundabout goes in the right direction.

5. Now demolish a 2x2 area at two opposite stretches of RHW and replace them by OWR like this (again, make sure the OWR is pointing into the right direction):

6. Now make a ERHW-overpass with the other two RHW-ends over the roundabout.

7. Then place some ramps at both ends of the overpass:

9. There you have it, a Standard Roundabout Interchange.

Variations for more experienced RHW-users
1. You can use RHW-6 at both ends of the overpass and use a C-type ramp or a RHW-6S/8S-Splitter instead of a A-type ramp.

Yup, made it myself based on the other ones in this guide.

When I do the full one (folded ramps on both decks  &hlp ) and the revised version of this one, I'll PM it to ya.


Ok, it looks good now. I'll add it to the table of contents under the name "Partially Unraveled Cloverleaf". If anyone wants to suggest a different name, I'm open to suggestions!

Add this to the top of your tutorial:

Section 4.3 Partially Unraveled Cloverleaf Interchange

Maarten, as I just stated to the publishers of the last two guides, please send me a PM containing your guide prior to posting it here in the future. That way we can make sure the guide can be as polished and accurate as possible.

If you could re-do your pictures using RHW 4.1 (the latest public version) and the current NAM then I can count your guide. In addition you don't need to add 8.3.x for each picture. You can number them 1, 2, 3, etc. if you want however. Please check the format of past guides for examples.

I would call yours a "Standard Roundabout Interchange" rather than a Dual-level Roundabout/Rotary Interchange as well.

Anyways, if you could make these changes I would love to add your tutorial to this guide! Please send me a PM in the future. Thanks!  :)

Cool! I don't have a problem with alternative names because junctions are called something different around the world. Take turbine/whirlpool ones for example.

I've been putting together a two-level cloverstack guide together over the past little bit. It seems as though RHW-RHW interchanges are in high demand these days. :P

Section 1.4: FLUP Diamond Interchange

This interchange utilizes FLUPs (instead of overpasses) to create a space-saving interchange able to have 2-lane (RHW-4) on/off ramps (though a plain MIS is shown in this guide) for higher capacity. This interchange is best suited for urban areas.

First, put down 2 underground road (FLUPs) ramps 4 tiles apart like this:

Then, put down 2 one-way road FLUPs ENTRANCE ramps like this: (For those of you who drive on the left, use exit ramps.)

Put down 2 one-way road FLUPs EXIT ramps opposite the entrance ramps like this: (Left-hand drivers, use entrance ramps.)

Put down your RHW-4 starters and drag them out for a few tiles each way.

Place an "Underground Route under RHW-4" puzzle piece like this. You will find this piece under the road/RHW interface menu.

Now put in 4-way junctions in the gap. I used a 4-way junction with a transparent surface. It will now look like this:

Place 4 MIS style-A ramps as close as you can to the ramp. It should look like this: (close-up of one ramp)

Drag your MIS-ramps so they connect to the one-way roads. Again, a close-up:

You're finished! Your interchange should look like this:

If you want, you can use Style-C ramps or even RHW-6S>dual RHW-4 splitters in place of the type-A ramps, or an avenue in place of the road. This will give you a more efficient interchange.

Death50's creation is different from mine as the loops are elevated (mine are not). It's also more complicated (my first one will be simple, without smooth curves and the lot). It's almost like a clover-turbine.

The cloverstack interchange is a hybrid of Parclo and stack interchange designs. It provides free-flowing access from all directions making them ideal for four-way highway-to-highway junctions. While cloverstack designs vary from two-level to three-level junctions, they all follow basic standards. Two loop ramps are included mirroring each other to eliminate weaving and two flyover ramps are included along with four ground-based outer ramps.

The cloverstack was designed to provide the weaving-free assets of the stack interchange while reducing cost and the total number of "stacked" levels required.

The guides in this section will show how to build two and three level variants of this interchange in basic and complex ways.




Section 11.1:  Basic Two-level Cloverstack interchange.

In this guide I will show you how to build a two-level cloverstack with a basic layout. I will also show how to compact this setup to make the interchange footprint smaller.




I will be using two RHW-4s for this guide with a 2 tile median. I feel this setup will make it easier to identify which directions the RHWs and the ramps are traveling. This gap also provides room for future RHW widening in the median.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg37.imageshack.us%2Fimg37%2F4232%2Fpinerymar1001294554233.jpg&hash=007158b7ec8025935094db4ed6f636c44945aaad)

Then it's time to build your overpass. The east-west RHW will overpass the north/shouth RHW in this guide. Plop your RHW-4 to El-RHW-4 "On" and "off" pieces next to the north/south RHW and drag the elevated segments to complete the span.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg651.imageshack.us%2Fimg651%2F5787%2Fpinerymar20001294554279.jpg&hash=e6c887985ba99f37c2f803ee7c3038cd11c7e1f4)

Construct two RHW-4 type "B" ramps on the north/south RHW immediately beyond the overpass. There should be a 0 tile gap. Use the drag method outlined in the video tutorial in the sticky post.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg651.imageshack.us%2Fimg651%2F3246%2Fpinerysep8011294717540.jpg&hash=61d46262f6510b8f91282f13236789fb0bbc1daa)

Do the same thing for the east-west RHW, except two tiles away from the start/end of the overpass like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg717.imageshack.us%2Fimg717%2F4237%2Fpineryoct6011294717604.jpg&hash=4f54cc8f9c12af087f3ca81c89e53c2681ed8b5c)

The next step is a big one. It's time to complete the loop ramps, but you have to complete the loops a certain way to allow for flyover ramps to properly go over the loop ramps. Construct as shown.
-For a little extra help you can plop a pair of El-MIS starter pieces inside the loop's circumference. You can also drag these out further. You will need the elevated segment anyways so I recommend building it at the same time as your loop ramps.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg524.imageshack.us%2Fimg524%2F9104%2Fpineryjun28021294719656.jpg&hash=ffc0c4ce451be6b7e52c7f071be550a12630bd02)

Now it is time to build your FlexFly curves. Align the elevated 90 degree MIS curve with the elevated MIS stubs and plop them one tile beyond the loop ramps. The end result will look like this.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg28.imageshack.us%2Fimg28%2F7133%2Fpineryaug9021294719750.jpg&hash=4ad50d98968db0704135c3f38c2e593920fa4353)

Plop 4 elevated MIS to MIS transitions as shown. Elevated to ground should take place immediately next to the north/south RHW while ground to elevated should take place one tile away from the loop ramp, allowing for MIS to run under it.
-Sorry if it's a little difficult to see, I'm using a new resolution for SC4 and resizing the photos makes them quite small.

Zoom in of the centre of the interchange. Go ahead and demolish the Flexfly helper pieces once you're sure everything is plopped correctly.

Connections of the elevated sections to the RHW is now possible. Drag the MIS stubs from the ground to elevated transitions and curve them toward the north/south RHW. This will also set the stage for the outer connections.

Continue dragging diagonal MIS until you reach the east/west RHW. Drag MIS from your elevated to ground transitions to meet up with the diagonal MIS. Connect everything together with 4 RHW-4 type "B" ramps. (It doesn't matter if you drag or plop them this time).

To finish, you need to create your two remaining outer ramps. Simply drag RHW-2 as close to the Flex-fly curves as possible.

...And your done! Congrats, you made a basic two-level cloverstack interchange!  :)




Additional Images

You can also make the interchange more compact by moving the outer ramps described in the last two steps of the guide inside of the flyover. Use RHW-4 type "A" ramps on the east/west RHW just beyond the elevated segment and plop RHW-4 type "B" ramps just before the elevated MIS on the north/south RHW.

Section 1.5: Compact Left Exit/Entrance Diamond Interchange with acceleration lanes

Here is a tutorial of a left-exit/entrance diamond utilizing FLUPs (though overpasses could be used also) and the RHW-6C>RHW-4 transition with center ramps. This allows for  (in fact it must have) an accel/decel lane (unlike the existing Left-exit/Entrance Diamond tutorial), and is also more compact than the existing tut.

Put down 2 FLUPs underground road ramps like this (1 tile apart):

Put down 2 more road ramps 1 tile away from the gap between the ramps placed earlier. It should look like this:

Put down a "RHW-6C>RHW-4 Transition with Center Ramps" puzzle piece (this is found with the MIS-ramps menu, not with the other transitions) as close as you can to the ramps you put down in the first step. Then drag your RHW-4's across the gap. When that's finished, it should look like the bottom picture.

Put down a 4-way FLUP junction in the gap between the two on/off ramps. I used a 4-way junction under a pedmall. Then, put two "Straight underground route under RHW-4" pieces (make sure the lines line up) in the remaining gaps between the 4-way junction and the ramps for the intersecting road to finish your interchange.

Excellent Tuturials here guys, I have already built a few diamonds and t-bones in my cities and completely replaced my maxis highways after I saw this thread. Also, I beleive I may have a new kind of cloverleaf, although it is probably better suited for lower capacities:

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg820.imageshack.us%2Fimg820%2F4064%2Fcloverleaf.jpg&hash=22e8fa2e43ea10dfa87438dbb4234fd2d030cc38)

I can't think of a name for it, I guess it should be a simplified compact clover or something. It could be made smaller if you got rid of the accel/decel lanes or just made them shorter.

Nice job with your guide gooper1! It's been added to the list. I would recommend making future interchanges on level terrain from now on though.


apeguy: That is probably the largest cloverleaf I have ever seen. It's so big the weaving problem associated with cloverleafs has been avoided. Nice work!

Compact?
Like Haljackey said, that is huge. For higher capacity, replace it with a cloverstack (see Section 11.1 above)-it will take up just as much land as your cloverleaf, at most.
Good job anyways.  &apls &apls

That interchange would be called a cloverstack (or a clover-turbine). Nice tutorial, though you can combine the two ramps in the bottom picture into an RHW-4 and merge it with the RHW-6S...It would make your interchange a bit more efficient.

Thank you, glad you liked it. Also, it's interesting you mention that... see this desgin was ment for the purpose of most traffic going thru and under the the freeway while the other route is more of an "expressway" with few cars, but simple edits can infact make them both high capcity interchanges. I'll post some pictures of that soon.

Nice job death! Your section number will be 11.2. Try to leave some space between your text and images as well so it's easier to follow along.

Now we just need a name for your creation. I'm thinking Standard Clover-Turbine Interchange but I am open to suggestions!

I might get a moderator to stitch your posts together. That way it will be easier to link your guide to the table of contents. In addition double (in this case triple) posts are generally frowned upon.

Anyways great work! I've added some more diagrams to the sticky post as well. Check them out, and if you want to make a guide for them, send me a PM.

Sorry for taking up so many post, but it seemed after I reach a point while typing in this box, it would glitch bouncing up and down making it impossible for me to type any more.

I would have to guess that you're using the latest version of Internet Explorer.  Simply click on the "compatibilty view" button at the top of your screen and it should solve your problem.   :thumbsup:

Oh yeah... nice interchange!  ;)

Really? I was thinking of "Two-Level Cloverfold Stack," due to the clover-folding. I managed to replicate that design recently (But with FA stuff and more ramps and WRCs, and a lot of eyecandy), and it... Works.

I also came up with a Diverging Stack Interchange... That's for the SUYI (Show Us Your Interchanges) Thread later on...

I was wondering what was causing my computer to bounce like that. Thanks for the tip JBS! And glad you liked it, thank you.

Thank you Hal, what an honnor, that my desgin will be looked at by others for use! Yes, I only posted so much from the bouncing problem, but now it's fixed thanks to JBS I think that problem will be solved. I took a crack at another interchange. Tell me what you think. I'm currently working on another.

@Haljackey: I have to agree with GDO29Anagram, that's not a Clover-turbine, because one of the main features of the cloverturbine is that the turbine ramps are completely outside of the clover ramps, as shown in the diagram on top of your tutorial

I also have a interchange design where I like to show a tutorial about: a high-capacity clover-windmill:

Nice job, I would think that would be a "diverging directional T" interchange (though IRL, I don't know if any exist). However, it is not free-flowing (due to the traffic light on the Diverging Diamond piece) and therefore has a relatively low capacity.

If you replace the diverging diamond piece with a bridge crossover, you would have a good, high-capacity interchange.

Section 4.4: Simple Elongated Cloverleaf Interchange.

Okay, this tutorial will be showing you how to build a somewhat unique kind of cloverleaf interchange, and probably the biggest type out of the examples shown here, as you can fit an entire maxis cloverleaf inside one of the leaves. Although this junction, like all clovers, is free-flowing and is full access from all directions, this is relatively low-capacity due to the unique design of the slip roads. So this would probably suit a rural area, where two low-capacity highways meet and need full access in all directions, and space isn't an issue.

So, let's build this thing. Start off by dragging two highways across each other. I've used RHW-4 because it's the easiest to work with. In this example I have use EL-RHW4 for the overpass because you can build the slip lanes closer together than if you used hole digging lots to create a smooth, gentle slope. Although it's less realistic, this time we're going for simplicity.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg836.imageshack.us%2Fimg836%2F1860%2Fclovertutorial1.jpg&hash=578621d5d67fb3448f3514aec7f1b59ba568ac17)


The next step is to build 8 RHW4 style B ramps, as shown in the image below. It is best to build them all the same distance from where the two highways cross, in this case, 10 tiles.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg232.imageshack.us%2Fimg232%2F205%2Fclovertutorial2.jpg&hash=5580fb4131f47f4bec8507c43e0cc1ed69bff9e2)


Next you need to extend the MIS ramps out from the ramps. Make sure that you extend all the ramps out the same distance. Here you can see that I have dragged the MIS until there is four tiles between it and the highway. This is the bare minimum. You will see why later on.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg266.imageshack.us%2Fimg266%2F9660%2Fclovertutorial3.jpg&hash=ef5e85f030da498bc8898d4062c0b73eeaab61af)


Next, place an RHW2 Splitter style A at the end of every MIS ramp, With the RHW2 end at a right angle to the main highway. Next drag the other part of the splitter ramp up to the highway and then turn 90 degrees. Now you can see why you had to extend the diagonal MIS out at least four tiles from the highway. This makes sure that there is enough room for the other MIS to make that 90-degree turn. Any smaller and it wouldn't create that smooth 90-degree turn.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg521.imageshack.us%2Fimg521%2F8678%2Fclovertutorial4.jpg&hash=1cbf8012340a5c9fa941b37318f88aecdd6c4f73)


This should be your finished result. Now you can see its design is starting to differ from that of a standard cloverleaf.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg89.imageshack.us%2Fimg89%2F6573%2Fclovertutorial5.jpg&hash=0acf57bdb1c58dc6652cac8ee2d25cb516751893)


Next you just need to add some RHW4 style A ramps to connect the remaining MIS ramps up. You're nearly finished now.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg684.imageshack.us%2Fimg684%2F8980%2Fclovertutorial6.jpg&hash=e7ed02c98c8da251d165748552e518ee83d9117b)


The final step is to just drag some standard RHW2 between the splitter ramps and you're done! You have a fully functional Simple Elongated Cloverleaf!

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg87.imageshack.us%2Fimg87%2F2403%2Fclovertutorial7.jpg&hash=727b1d48e3b39fc88b129644907069809e25a435)


You can easily customize your clover, for example adding smoother curves to the slip lanes, or even adding accel/decel lanes, but this will require you to increase the overall size of the interchange, if it wasn't already big enough as it is. As mentioned before, this suits a more rural setting due to its low capacity, and as far as I know, no real-life versions of this clover exists. If someone can find one, that would be interesting to see.

Turbine interchanges are large high-speed and high capacity RHWxRHW interchanges. They take up lots of space and cost a lot of money, but are still cheaper than stack interchanges. This is one of the most efficient interchanges that exist. So let's recreate one in SC4.




Section 12.1: Standard Turbine Interchange.

1. Here's our location for our interchange, where two RHWs meet. I left the middle intentionally blank.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg203.imageshack.us%2Fimg203%2F4241%2Ffullturbinestep01.jpg&hash=e442131bdc2b0f3a1a093a1d58d75ffb229d461a)

2. Next we make some helper stretches of RHW. These helpers are in-line with one stretch of the RHW and will be demolished later, but they can help with getting the dimensions right.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg217.imageshack.us%2Fimg217%2F6153%2Ffullturbinestep02.jpg&hash=ee3dd47b8cb54173df1e997e83430f8f4f2a16b2)

3. Next we lay 1x1 road stubs of 12 tiles long at either side of the helper stretch. Note that these tiles are in-line with the other RHW.

4. Now use a hole digger to make a tunnel entrance slope. Place these hole diggers one tile away from the 1x1 stubs.

5. Now place a A-wide or a FARHW-ramp at the flat section before the tunnel entrance.

6. Demolish a 2x1 area of the stubs and lay some RHW there. Connect the MIS ramp with a B-style RHW-4 ramp.

7. Now place a RHW-4 Smooth Outer curve. Don't worry about the stubs now...

9. Drag out the RHW-4 from the stubs (re-drag the curve if it doesn't work immediately)...

12. Repeat Step 4 to 11 at the opposite side of the interchange.

13. Demolish a 2x2 section of the stubs and drag a stretch of RHW on tile away from the other RHW-4 ramp. If it's right, you'll now have an area of 2x9 tiles of road stubs.

21. Use hole diggers to make some OWR-tunnels. MAKE SURE NO ROAD TILES SURROUND THE TUNNEL ENTRANCE! Otherwise they will be demolished and can't be build on these locations again.

23. Repeat step 19 to 22 a few times and connect the RHW ends from the other ends of the OWR tunnel to the main RHW. As you can see, this interchange barely fits in a small city tile, giving you the idea how large this interchange is.

24. Now we lower the center like this with hole diggers.

25. For one of the RHWs we make an overpass. You can do this by sinking one of the RHWs even further or when it can't be done (in this case, because I would be building under sea level) raise one of the RHWs like this.

27. Drag out the stretches of RHW from the overpass and drag a RHW-4 underneath it:

28. The following step can be tricky and doesn't always work out that well. Connect the RHWs in the middle to the main RHWs on the outside with Avenue tunnels. Now here's the tricky part: the OWR-tunnels might disappear. When this happens, flatten the tunnel entrance ramps for these tunnels and repeat step 19 to 23. This happened to me when I was making this guide. Anyway, the end result looks like this:

That will do for this interchange.

Looks great, Elias, although I would make a few changes:
- I would use OWR FLUPs instead of overpasses.
- I also would use a ERHW-4 overpass instead of an avenue overpass.
- Just for a finishing touch I would use FARHW-4 ramps instead of MIS-ramps.

Section 13: Volleyball Interchanges

This is a rare interchange that is better known as the 3-level diamond or split-level diamond. All turning motions are handled in an intermediate square structure connecting the eight ramps. Turning traffic travels around the square in the same direction as a roundabout in that country. Through traffic can proceed on either intersecting road without stopping.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.kurumi.com%2Froads%2Finterchanges%2Fvball.gif&hash=a939a1ce80bff00be8f06986f6267dd71e683409)

Here is an example. Suppose you live in a right-hand driving nation, like U.S.A., and want to exit northbound on the thick black ramp of the above image. To go east, simply take the blue ramp: a simple right turn. To go west however, you would take the green route, which involves merging and crossing other traffic!

Advantages of the volleyball interchange include the ability to locate in it a narrow space along the two rights of way: more capacity than a diamond, and less space than a full cloverleaf. The volleyball's disadvantages however include a large number of bridges and low capacity compared to more directional interchanges. Because of the above reasons, Volleyball Interchanges are rare.

Section 13.1: Basic Volleyball Interchange

For this tutorial, we're going to build an avenue -  R.H.W.-4 interchange. Tutorials for extra variations are coming soon. First, build the R.H.W.-4 and the avenue as the picture shows.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg202.imageshack.us%2Fimg202%2F7812%2Ftutorial1xj.jpg&hash=ee4bd1e916f530c2d1e4ff4c9b2fb4e52da7923e)

With the one-ways, build the central roundabout. There should be a 5 tiles gap between the one-way and the avenue, as you can see with the red dots. Same with the R.H.W.-4. You'll end up with 4 5x5 squares. But which is the best route to drag the one-way? The roundabout should be clockwise if you have a Left Hand Driving game. If you have a Right Hand Driving game, make the roundabout anti-clockwise.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg402.imageshack.us%2Fimg402%2F2540%2Ftutorial2u.jpg&hash=2d2a9743aee5253f5c35fda63600a1fff5b7f464)

Drag the one-ways with the right direction at least 1 tile from the crossing (brown dots).

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg96.imageshack.us%2Fimg96%2F4306%2Ftutorial3n.jpg&hash=4632f8dbd261317269d467167618bece6cdd4923)

Time to build the avenue ramps. We'll use one-ways again. In later tutorials, we'll use other variations. Build a 2 tiles straight one-way (red dots) and a diagonal to the avenue. The avenue - one-ways intersections will be 6 tiles (purple dots) away from the roundabout.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg413.imageshack.us%2Fimg413%2F8051%2Ftutorial4n.jpg&hash=4ad1ea22eb9abb314e7d8d412ded37a96ad0b4fe)

By using Fl.U.P.s, built one-ways underpasses under the R.H.W.-4. Make sure that the exits and the entrances were added in the right direction. We can use one-way overpasses as well, while the underpasses will make your interchange more elegant.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg842.imageshack.us%2Fimg842%2F5451%2Ftutorial5.jpg&hash=7b7ad5e7c47ab07f21b6eb37d0e5d1f834bd3a60)

Remove the flat avenue and make in elevated, to built an avenue overpass.

Time to connect the highway with the interchange. This is tricky, so be careful. Add R.W.H.-4 started pieces at least one tile (green dot) away from the one-ways crossing. Make sure that the arrows of those pieces looks in the right direction (yellow arrows).

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg407.imageshack.us%2Fimg407%2F3798%2Ftutorial7.jpg&hash=1b944e665ef09486dba8eb8cbee1ffdf316e85bf)

Drag the one-way for only 1 tile and then drag the R.H.W.-4 to build a connection.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg573.imageshack.us%2Fimg573%2F2060%2Ftutorial8x.jpg&hash=97bad6a9860e5d6a00a3c6ab40268408866f6e02)

The speed of the cars in the highway will be larger than the speed of the cars in the avenue, so they need a smoother ramp. Build smooth R.W.H.-4 corners as you can see in the picture.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg717.imageshack.us%2Fimg717%2F9726%2Ftutorial9.jpg&hash=eca5016b9f7daf89b055f9e19934b90b71e87a3d)

Connect the ramp with the highway by using R.H.W.-6/Dual R.H.W.-4 Splitter Ramp (5x3). Use the R.H.W.-4 fillers to build the ramps. The highway itself looks a little messy. Don't worry, we'll fix it.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg30.imageshack.us%2Fimg30%2F8995%2Ftutorial10c.jpg&hash=d91f01920a7d013cc505d9625e3e5f7b6dbe6709)

In the in-the-interchange side of the highway, remove some R.H.W.-6 parts and replace them with R.H.W.-4. Be careful, don't remove the parts that are too close to the ramps or the underpasses.

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg228.imageshack.us%2Fimg228%2F2567%2Ftutorial11.jpg&hash=9793a8aed880cef01908b7a44620c1a39a3d31f0)

As about the other side, make a 3 tiles gap (blue dots).

Built a R.H.W.-4 to R.H.W.-6 transition. A good idea is to use a nice one from the "cosmetic pieces".

Looks good Elias! I've added it to the list. Volleyball interchanges have always been somewhat of a mystery to me. I was never sure why they are designed the way they are. You could almost call it a double-diamond because you essentially have two diamond interchanges intersecting with each other.

One thing that strikes me on the diagram and your guide is the lack of connections without the use of an intersection. It would be easy to have right turn slip lanes (RHD) on each of the four corners, creating a "star" shape. In addition the interchange doesn't have to be three levels either, you could have all the under/overpasses on the second/underground level.




That guide completes all of the RHW to Road or Avenue sections of the RHW Interchange Guide. While some of these sections are still a little light, all have at least one entry in them. If anyone would like to suggest additional RHW to road or avenue interchanges I'm all for it. Be sure to attach a diagram and/or real world example as well.

The solution is really quite simple, it's all about the cost vs. benefit analysis for designing an interchange. These work decently for handling a moderate amount of traffic without interrupting the flow on the mainlines. Texas likes to use these when rural divided highways/expressways intersect with the provisions for adding flyovers at a later date if traffic warrants their construction. Check out this intersection of US 59 and TX Loop 589 in Lufkin, Texas for an example: http://goo.gl/maps/PLRt (http://goo.gl/maps/PLRt).

Volleyball interchanges are weird... Though, they do have their places. The only one in QLD I know of is where the motorway is coming off a hill and the slope is continued across the Arterial Road and Interchange.

Old Cleveland Road vs. Gateway Motorway/Arterial if you're interested. (http://maps.google.com.au/?ie=UTF8&ll=-27.503704,153.125145&spn=0.00786,0.021136&t=k&z=16)

Some of the ramps are two-way and there are Exiting Lane slip ramps all around... If you don't know it, it's very confusing to use.

Section Twelve: Turbine Interchanges

I have a few questions:

  • First, that interchange is WAY too big to be practical.
  • Second, can't you just remove the RHW overpass (and the RHW under it) in the middle and replace it with two tunnels that go all the way through the interchange? Tunnels can pass over/under each other...
  • Third, this interchange is designed for left-turning (right-turning in LHD) traffic (it has 2 exit lanes)--right-turning traffic (left in LHD) only has a one-lane exit. However, this can easily be rectified by using RHW-6S>dual RHW-4 splitters (instead of MIS style A or B ramps) and placing RHW-6S>RHW-4 transitions where needed.

Great job, though.  &apls &apls

I know, but tunnels are very expensive in RL. That's why I left the middle open. Also, I wanted an underpass in the middle of the interchanges, but the hole diggers wouldn't allow be to build so low (probably because I would end up under sea level), so I built an overpass.

Wrong! It's designed for RHD (I'm dutch, so I have the RHD version of SC4)! However, I do agree there might be better designs than this, but this would make this interchange even larger and unpractical. Above that there are some yet unexisting RHW-pieces that I need to make an improved version of this interchange...

Section 14.1: Standard Directional-T Interchange

This guide will help you create a high-capacity, free-flowing, high-speed, and compact three-way interchange known as the directional T interchange.  Directional T's are also called full Y interchanges.  The semi-directional T is a variation on this type of interchange, with outer (in the right-hand drive case, right) exits instead of inner (left) exits like this one.  This type of interchange has faster speed limits than those of a trumpet interchange, as no loops ramps are used and the curves are more direct and gradual.  However, this has the disadvantage of having more bridges, which some people don't like to see.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2Fa%2Fae%2FKnooppunt_driehoek.png&hash=c446a8182205c8807dcea6888ac3f45bc090a7a2)

This guide uses an interchange between two RHW-8S highways, but the same concepts apply to RHW-6S.  All ramps in this tutorial are RHW-4; no MIS ramps are used, which gives the turning movements a high capacity.  Click on the images for to see their full versions.

First of all, place two RHW-8 dual RHW-4 splitter puzzle pieces next to each other like shown.  This will be your terminating highway.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.picpanda.com%2Fimages%2Fw4tq8qhzl9xhmg2plvfb.png&hash=564a631086a5e16807db10567adced7d7e625f9f) (http://www.picpanda.com/images/u6mn9xkdhlmq07uzu5lo.png)
NOTE:  You can use the 45° curved splitters here, but you would need to push back the curves and take up a lot of additional space for the interchange if you do that.

Next, place a RHW-4 ground-to-elevated transition with the starter stub shared with that of the splitter, as shown:

Drag a ground RHW-4 45° curve to the right as shown, connecting it to the inner stub of the other splitter puzzle piece (first picture), then drag a curve to the left starting after making an overpass for the flyover ramp, as shown in this picture (the brown highlighted one):

NOTE:  To drag an ERHW over a diagonal ground RHW, drag the ERHW halfway over the diagonal ground RHW (only one tile of the diagonal), then do the same, starting from the other side, for the other half; do not drag the ERHW-4 all the way over the ground RHW-4 in one stroke.

Then plop a RHW-4 ground-to-elevated transition to end the curve.

Plop a RHW-4 ground-to-elevated transition in the location shown, and drag ground RHW out from it halfway under the ERHW-4.

Next, plop a 45° RHW-8 to dual RHW-4 splitter, noting the tile arrangement if you want to have a continuous curve like in the picture.  Drag RHW out from the orthogonal starter stub under the other half of the elevated RHW.  Also plop a smooth 45° RHW-4 curve to complete the 90° right turn, connecting the curve's end stub with the starter stub of the RHW-8 splitter you placed earlier.

Now continue the diagonal RHW you made earlier.  Make sure you drag it to the same length as I did in the picture, or else the overpass you will soon build won't work.

Then plop a RHW-8 dual RHW-4 splitter a few tiles away from the end of the diagonal, to the east, and finish that part by connecting the diagonal to the inner starter stub of the splitter:

You will need to click (but don't drag) once at this place to get the entire diagonal RHW to change to RHW-4:

Plop another RHW-4 ground-to-elevated transition on the diagonal's other side, and drag the two halves separately over the diagonal ground RHW, similar to the first overpass you made.  Plop a RHW-8 dual RHW-4 splitter with it and the ramp sharing a starter stub, then create RHW-4 45° smooth curves as close as possible to the already-existing diagonal RHW-4.  Connect these curves to the nearby starter stubs from the RHW-8 splitters, and connect them together with diagonal RHW-4 filler pieces.

However, that's not a Directional T, it's a Full Y, and the picture Haljackey posted as a reserve image for a Full Y is a Directional T. The main difference is that Directional T's are usually 3-level (making them hard to build with the current RHW), and Full Y's are almost always 2 levels.

We already have a Full-Y interchange piece in SC4 for the ground highway and avenue. A guide how to make one for the RHW has not been made yet.

In addition, there is a difference between a directional and semi-directional-T.

I've modified the list to reflect this. Does anyone have a diagram of a Full-Y interchange like the avenue and ground highway setups in SC4? I can't seem to find one.

I'm working on a three-level cloverstack guide.

Well, let me contribute one. I call it a "Clover-bout" It is a mid-size interchange for EL-RHW4 intersecting with an avenue. Useful for heavily-traveled districts. I got the design from one of the interchanges on the game Saints Row 2 while watching my brother play it. This basically contains 2 AVE-Roundabouts, an EL-RHW4, and a stretch of AVE.

Guide for interchange: (Yes, I did it in MS Paint) But the blue is the AVE, blue dots= AVE Roundabout, Black: EL-RHW4/MIS. Feel free to make a diagram of it. I stink at photoshop...

I don't see the point of this interchange. In fact, a cloverleaf using curved MIS El-2-ground-transistions takes up less space...

Seconded. In addition, you did not follow the procedure set up for contributing a new tutorial to this guide (see the sticky post, please). That will have to be corrected before it can be added. What section of the guide would this tutorial belong in? Also, why such small pictures and a blurry diagram?

Section 11.3: Three-Level Cloverstack Interchange

When it comes to full highway exchanges in Simcity 4, the three-level cloverstack is among the best ways to hook up any two intersecting RHWs.

With the release of RHW 4.1, the three-level cloverstack is able to become much more compact and thus more justifiable and practical. Cloverstacks made with previous releases are gargantuan to say the least.

Although I will try to be as simplistic as possible, this will be my most complicated tutorial in the RHW Interchange guide to date. I hope you are all able to follow along! If not, please let me know where you are having trouble in the guide and I can explain those steps in greater detail.

Also, make sure you are familiar with filler puzzle pieces as they need to be used in this guide.

You will need hole digging lots for this guide. Using a slope mod is highly recommended as well. I will be using the RHW slope mod for this tutorial.




Let's start out simple. Drag some RHW. Make sure you delete the starter pieces.
-For this guide, I am using RHW-4 with a 0 tile median.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg194.imageshack.us%2Fimg194%2F7521%2Faragothmar2500129642427.jpg&hash=fe04c0586738e3af1138f2ee826388f8ecaa2f55)

And here's where things get different. We are going to make our two MIS flyover ramps from the get-go. Getting the centre part done now will make the rest of the interchange easier to build. Plop diagonal-MIS over RHW-4 filler pieces just as shown. Be sure to rotate to make sure the lines meet up.
-If you encounter some alignment/lining errors, bulldoze the area and try again. This may require a some trial and error. That's why we're getting this step done first.  :P
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg814.imageshack.us%2Fimg814%2F497%2Faragothaug2400129642459.jpg&hash=e46efa12249e5e1e00c84620cab49fdaf133846b)

Plot a course for your perpendicular RHW. Since the flyovers create a 3x2 rectangle in the centre, the interchange will not be completely symmetrical (unless you include a 1 time median for one of the RHWs or between the flyovers). Your RHW can run either to the north or south of centre. In this example I am routing it slightly south.
-Just use road stubs for now. This route will ultimately tunnel under the centre of the junction.
-Leave three tiles empty on either side of the north/south RHW.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg9.imageshack.us%2Fimg9%2F3540%2Faragothdec1300129642489.jpg&hash=849f1ab182d961d7a4812256f4a5912d2d9d32e3)

Plop your MIS to elevated MIS transitions. Use the grid and/or road stubs to properly align your pieces as shown. Do not use the "starterless" versions.
-You don't need the "on" transitions yet... you can use a el-MIS starter piece in its place. I am using the transitions for the moment so it is easier to follow along.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg203.imageshack.us%2Fimg203%2F2905%2Faragothmar1401129642509.jpg&hash=ce075def33b7ba667d76c4925e23230448ca4019)

Drag elevated MIS from the transitions towards the centre of the interchange like so. They will not fully connect, so don't worry about it for now.

Place diagonal MIS filler pieces to hook everything up. Again, be sure the lines match up for a proper connection.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg820.imageshack.us%2Fimg820%2F1218%2Faragothmay2101129642528.jpg&hash=097a4a2fb0a7dbb3e142639be7096c88218a508e)




Congratulations, you just built the flyover ramps!

Save your game. That way you won't lose all that hard work if Simcity suddenly crashes.




Delete your road stubs. Place hole digging lots 4 tiles away from the north/south RHW.
-For this example I am using hole diggers for avenue.

Congrats! You have now completed the central part of the interchange. It's finally starting to come together, isn't it? :)

Save your game. This is a very intricate part of the junction and it would be sad to see it vanish if Simcity 4 suddenly crashed. Also, if you demolish a part of the interchange by mistake you can always exit and come back to this save point.




Two overpasses left to go. Create "on-slope" ground to elevated MIS transitions near the exits to the loop ramps. Demolish the road stub placeholder to place the elevated to ground on-slope transitions.

Drag your RHW out of the trench. Plop a mirrored pair of RHW-4 type "Wide-A" ramps where your RHW reaches level terrain and connect it to the overpasses you just made. I know there are other ways you can connect the MIS to your RHW but I want to keep it simple for this tutorial.

This might not be the right place to post this, but I wanted to see if people knew you can actually do stack interchanges.

Do people just not use them because of the lack of realism of having one tunnel cross the other (albeit at a different level, and SC4 does allow traffic to flow freely).

Something like this.  (unfinished, sorry for sloppiness)

I've seen many people use tunnels to make three-level stacks, and even four-level stacks. Though it's a little unrealistic in some cases, it works as the best current workaround. Though if you set up your tunnels correctly, they can actually spice up an interchange.

Also, once multi-level RHW is released, stacks with up to five levels will be possible.

Why not check out the "Show Us Your Interchanges" thread for more examples? There's bound to be people who use Ave or OWR tunnels in their interchanges, and maybe even a three-level stack or two...

Introduction

The diverging interchange is a new breed of interchange, and is still mostly in the theoretical stage of development (in real life...obviously). This guide will show you how to build a Diverging Windmill Interchange (DWI...no, no, no, not "Driving While under the Influence", my Canadian friends), which is an interchange where both thoroughfares diverge, or cross over themselves, with drivers temporarily driving on the "wrong" side of the road (right-hand-drive countries would drive to the left of the median, left-hand-drive countries to the right of the median). While some of these crossovers may be signalized in an actual interchange, this guide will assume that all crossovers are free-flowing, to show how this concept could be applied to SC4 RHW-RHW interchanges. This particular variation is the one off-ramp, two on-ramp kind, but can be inverted to create a two off-ramp, one on-ramp design, which replaces a left-side entering lane with a left-side exit lane. (In the case of left-hand-drive, this design must be inverted, visually speaking, to provide a one off-ramp, two on-ramp variation. Pay attention later to outbound and inbound lanes.)

This guide assumes that you have a fairly thorough grasp of RHW networks, particularly FLUPs (FLexible UnderPasses). If you're having trouble understanding how to make this interchange, try building a few of the simpler interchanges instead.

Advantages and Disadvantages: When Should You Use it?

A DWI is a very high-capacity, high-speed interchange, with...get this...no movement conflicts. The dreaded left turn is eliminated, as is any weaving. The greatest thing going for the DWI is all traffic leaving the freeway exits before any new traffic comes on, reducing congestion (unlike nearly all configurations of the Cloverleaf). Furthermore, unlike the Windmill, the DWI doesn't require fly-overs, and so will conserve some space in the corners, making more room for a dense urban setting. (Many variations are possible, with different distributions of the footprint, but for the sake of this guide, I opted to compress it along the sides of each freeway as much as possible.) The DWI is also a much simpler design than the Turbine, Windmill, or Whirlpool, saving space, pavement, construction costs, stressballs, etc.

Another advantage is that the ramps and exit lanes, as well as most of the FLUPs pieces (not the FLUPs ramps), can accommodate other transit passing over or under them, such as HSR, monorail, rail, roads and el-rail/tram lines, as all the ramps are on the ground.

That said, it can get a wee bit complicated to build, mostly because traffic is going in opposite directions than usual in parts. Care must be taken to make sure you place everything correctly; I've made the mistake of putting FLUPs ramps or on-ramps backwards because of the confusion. I suggest copying the above diagram (included instead of the wikipedia one because it includes directional arrows), or better yet, plotting the interchange on 20cmx20cm piece of paper; that way you'll have something to refer to if you get lost, and you'll have a better understanding of how this thing works.

Due to the lack of RHW6, 8, and 10 "inside" ramps, this interchange is also only useful for RHW4-RHW4 networks, without rather significantly increasing it's size. In a later guide, I will show how the larger RHWs may be accommodated with flyover ramps or FLUPs pieces, as part of a Diverging Partial Cloverleaf Interchange.

Also, due to the incredible pain it is to conceive, let alone construct a grade-separated diversion of RHW4 highways using elevated pieces, all through traffic and left movements must pass through a few tiles of FLUPs One-Way-Road (OWR). Only three, not including ramps (eleven including ramps) but it's still a bottleneck (no worse than an OWR tunnel though). Right movements are completely free-flowing.

Small footprint, high capacity, and ease of upgrade make this one of the best interchange designs in SC4 (and in real life too).

General Notes

While technically an RHW-to-RHW interchange, this may also be used to upgrade a failing Diverging Diamond Interchange, Avenue-to-RHW.

Preparing the Grade-Separated Junction

Right, on to actually making this thing. Below is a crossing of two complete RHW4 freeways (traffic heading in the "correct" directions). I've added some road stubs to demarcate the ground as a visual aid; they are not required.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-01.jpg&hash=00a9e01b9a1402535ef518c5ea3bb7037f443084)

Next, plop down some road stubs to demarcate one of the freeways. Place four 8-down hole digger lots in the configuration below. Note that they are just outside where the two RHW4 freeways met, and that they are all perpendicular to the demarcated RHW4 (N-S).
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-02.jpg&hash=03959ff1886c6c4b05aafea33a98a9a20b4b7fa6)

Now, drag enough road to satisfy whatever slope mod you are using, like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-03.jpg&hash=8d887ed8ee852afc9d18ea84ae0d97fd90790f23)

Delete the roads, and use stubs to ensure that a 4x2 area is flat in your new trench.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-04.jpg&hash=422ed6019b59827173d24573ccdb8748408f2a94)

Leave the stubs, and now plop four 8-up ground lifter lots, perpendicular to your new trench, three tiles away (two tiles from the slope). Drag road as below:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-05.jpg&hash=92074f035c351ca0d9bb637172034bfdcfdb51f6)

Be careful. Drag that road one tile too far and all the road stubs will come flying up...you know, they probably don't need to be there, but I'm picky. And this is a touchy interchange, to say the least (more on that later).

Now that that's done, trash all the roads and stubs. Get-out the RHW4 ON SLOPE transition pieces, and place them as below. The yellow lines go on the outside, and direction of traffic is reversed from normal.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-06.jpg&hash=f8f6017c83acd0c0835391adf970b8ed9859bb67)

Because of how the ground was prepared, the transition pieces should connect to each other nicely, and also lower the terrain behind them a bit. This is a good thing! The shallower the grade, the quicker we get back to the original level, the quicker we can place entrance ramps. (That, and in this case I opted for a dash of realism, trying to reduce how many changes in grade must occur for each thoroughfare...well, ignoring the FLUPs tunnels, but that's later.)

Now, plop a couple RHW4 starter pieces, in the same configuration as the overpass, with traffic going the "wrong" way. Drag-out RHW4 underneath the overpass, and delete the starter pieces:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-07.jpg&hash=1cfa412737012a25c2209a8c8a4051bf2ddcad83)

Exit Ramps

Okay, on to our exits. The first exits will be on the inbound lanes. That is, the lanes that are travelling toward the overpass. We aren't going to plop these. Instead, we'll use the override to get a Style-B "Inside" entrance ramp, which doesn't have a puzzle-piece. Start an override like this:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-08.jpg&hash=4d7d23cd04f4a7871cbb67af8adeb43862db0e55)

Then drag diagonally out from that stub:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-09.jpg&hash=8e6e0b7424a5cbbbcd4c353da5cc223fa6dd496d)

And you should get this:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-10.jpg&hash=640b90418b9afe10f44df79ebb6bac88f5131225)

Now, see that bit of MIS going backwards? Don't worry about it. We'll change it later, but that bit is going to make this particular ramp a bit finnicky later, as it will keep switching directions to the wrong way. Just a warning; it's a side-effect of using the override instead of the Style-A Inside puzzle-piece, in order to save space.

Your results may vary depending on your slope mod, and if you changed the design of the overpass/underpass. Just get it flat. I can't stress this enough. Keep the ramp, and the RHW4 opposite to it, FLAT. FLUPs ramps are incredibly neurotic about being placed on level ground, so if there is even a hint of a grade change on your ramp segment, go back, level, try again, or put it farther out. Or, accept the change in grade, but make sure you've got level ground running next to it.

Now that you have one entrance, rinse and repeat:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-11.jpg&hash=485f4ea358bd5b216e7e776586e01c772e1effe0)

Crossover Sections (Diversions)

Now, to build our crossover sections. Start by plopping five tiles of stubs along the RHW (as a handy guide to make sure you have room for FLUPs; alternately, you can place the FLUPs pieces first), then an RHW4 lane shift, to get your inbound road on the "correct" side of the road:

Plop a FLUPs OWR entrance ramp, and one piece of diagonal FLUPs-under-pedmall.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-12.jpg&hash=503cf4343a62253327ae8314ae1f4cd765f5cb9c)

Plop a FLUPs OWR exit ramp on the opposite side, and another diagonal FLUPs-under-pedmall. Then just plop a FLUPs-under-RHW4 segment to crossover the opposing lanes. Plop an RHW4/MIS1 Type-A entrance ramp in front of the FLUPs OWR ramp. Yes, that is two entrance ramps, running on the same side of the road, in opposite directions. Wacky!
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-14.jpg&hash=1a717971bc0b912e38a6ca9e2ba2c8e6e7c85deb)

Repeat three more times, until you get this:

Now, take a break, get a cup of coffee, and congratulate yourself. The hard part is done. Now all we have to do is connect the ramps! :)

Final Steps: Connecting the MIS

Drag out MIS ramps toward what will soon be your off-ramp. This will help you in plopping the next pieces.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-16.jpg&hash=df95cf2316b35067a997a46f342106b4da7721b8)

Now, plop an RHW4/MIS-1 Dual Splitter A so that it connects to your ramps, then an RHW-6S/RHW-4 Dual Splitter Type A Exit to join that to your freeway. Join it all up:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-17.jpg&hash=bb1f9b2b8eb8dae32a460bcdc29f1cdcd76065a3)

Add a transition piece (RHW4-RHW6) somewhere before the exit, and redraw the stray piece of RHW6. You can see below I added a lane-shift to the opposing lanes, as I'm trying to save as much space as possible. Clearly, this isn't necessary if the original freeways had medians.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-18.jpg&hash=ad9f3cc0b216eb635574e30318799fa59513c978)

Repeat three times more, and you will have something like this:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdwi%2FDWI-19.jpg&hash=10d8d0f0bab300670124c736ba8c1de8d02c7a33)

And there you have it. A fully functional DWI that will fit nicely into a dense urban environment in need of a high-capacity interchange!

Variations

Here is a demonstration of the above interchange, with the ramps inverted, so that we have a two off-ramp, one on-ramp configuration:

The key to making this variation lies in where we place the FLUPs ramps. In this configuration, the inbound lanes crossover with FLUPs, instead of the outbound lanes as in the above guide.

@CrimsonPhoenix: Not to be a backseat moderator here, but did you talk to Haljackey about posting this? (I'm just wondering, since it looks like your first time here.)

Also,... FLUPs?!! :o How did I not think of that...? I was far too busy going elevated... Authorised or not, this REALLY gave me some ideas... And since I'm all caught up in an exchange of ideas, here's some advice for you: A bit of FARHW wouldn't hurt here and there.

Very cool. Your slopes are a little wonky, but you get your point across.

Interesting use of One-way FULPs to get around the whole diverging issue. This could be done with RHW flyovers, but would substantially increase the size of the interchange.

@Ganaram: CrimsonPhoenix messaged me about it. This FULP placement strategy has unlocked other diverging derivatives.

It's been added to the table of contents. Awesome work CrimsonPhoenix!

Heheh. I know, right? I spent a while trying to get the darn things to diverge right with diagonal pieces. It was a nightmare to even come close. Using FLUPs keeps it nice and compact. As far as the FARHW pieces go, meh. Readers are free to add 'em. ;)

I've updated the guide so that through and left movements only have to pass through three tiles of FLUPs (eleven counting ramps), reducing the bottlenecks. Pretty sure this is the limit now as far as compaction is concerned.Most importantly, I added how to get a Style-B Inside ramp, using overrides. I ran into this nifty feature while constructing the DivParClo.

I'll have Diverging ParClo and Expanded Diverging Interchange guides up soon. I'm at a loss to find a clear advantage to the Diverging Double Roundabout styles though, over the others. I may make a guide for them later, but the former two have far clearer advantages.

Haljackey, might I suggest that Section 15 just be "Diverging Interchanges"? Given that only the windmill-hybrid shares characteristics with the windmill.

I'm going to have to rethink how the diverging guides are structured as section 7 contains the diverging diamond interchange. How about section 7 will be used to house arterial/RHW diverging junctions (with intersections like the diverging diamond piece) while section 15 will be for free-flowing RHW-RHW diverging junctions? I'm open to suggestions!

Introduction

The diverging interchange is a new breed of interchange, and is still mostly in the theoretical stage of development (in real life...obviously). This guide will show you how to build a Diverging Partial Cloverleaf Interchange (DPCI), which combines two of the most efficient interchange designs into one: The Partial Cloverleaf, combined with diverging elements. In this interchange one highway has a crossover movement, with drivers temporarily driving on the "wrong" side of the road (right-hand-drive countries would drive to the left of the median, left-hand-drive countries to the right of the median). While this crossover may be signalized at-grade, this guide will assume that are grade-separated (free-flowing), to show how this concept could be applied to SC4 RHW-RHW interchanges. Because there is only one crossover movement, and the DPCI converts two movement which would be left-lane (right lane for left-side drive) to the right, meaning that unlike the Diverging Windmill Interchange, this one can be used for RHW4-RHW6S, 6C, 8S, 8C, or 10 crossings.

This guide assumes that you have a fairly thorough grasp of RHW networks, particularly FLUPs (FLexible UnderPasses). If you're having trouble understanding how to make this interchange, try building a few of the simpler interchanges instead.

Note that this design can be inverted, to change which two quadrants will be least affected by this interchange. Doing so provides no other advantages.

Advantages and Disadvantages: When Should You Use it?

A DPCI is a very high-capacity, high-speed interchange, with no movement conflicts. Left turns are eliminated, as is any weaving. Like the DWI, all traffic exits each freeway before any enters. The DPCI also requires very little room for right-of-way (that is, it has a very small footprint) in two quadrants, just like the Partial Cloverleaf.

Another advantage is that the ramps and exit lanes, as well as most of the FLUPs pieces (not the FLUPs ramps), can accommodate other transit passing over or under them, such as HSR, monorail, rail, roads and el-rail/tram lines, as most of the ramps are on the ground.

That said, it can get a wee bit complicated to build, mostly because traffic is going in opposite directions than usual in parts. Care must be taken to make sure you place everything correctly; I've made the mistake of putting FLUPs ramps or on-ramps backwards because of the confusion. I suggest copying the above diagram, or better yet, plotting the interchange on a piece of paper; that way you'll have something to refer to if you get lost, and you'll have a better understanding of how this thing works.

Also, due to the incredible pain it is to conceive, let alone construct a grade-separated diversion of RHW4 highways using elevated pieces, all through traffic and left movements from the RHW4 must pass through a few tiles of FLUPs One-Way-Road (OWR). Only three, at the bare minimum not including ramps (eleven including ramps) but it's still a bottleneck (no worse than an OWR tunnel though). Right movements are completely free-flowing. This guide uses extra FLUPs pieces to achieve a cleaner, as slightly more realistic look. (Though in reality, a diverging interchange would more likely use flyovers than tunnel underneath itself to achieve grade-separated diversions. Oh well.)

Exceedingly small footprint, high capacity, and ease of upgrade make this one of the most efficient interchange designs in SC4.

General Notes

When building this interchange, the diverging road should be the one that handles the least traffic, such as an arterial, or RHW4.

While technically an RHW-to-RHW interchange, this may also be used to upgrade a failing Diverging Diamond Interchange, Avenue-to-RHW, as well as a failing 4-way RHW interchange that has weaving movements, like the Cloverleaf (in which not all traffic exits each RHW before new traffic enters).

Construction: The Junction

Alright, so to demonstrate quite clearly how this diverging interchange can accommodate the larger RHW sizes, I've built an RHW4 meeting an RHW10:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdpci%2FDPCI-01.jpg&hash=144769116470abaeec6f8567ffa971e56bc93e4e)

Now, bulldoze the RHW4, plop RHW4 starter pieces to reverse each lane's direction of travel, and drag it out again, like so:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdpci%2FDPCI-02.jpg&hash=b6fe7d5b722e4db079cc619c387444d0b5086229)

You'll see that I left some stubs before I bulldozed the original RHW4. This was to help in plopping the starter pieces. Bulldoze them now if you used them yourself, and put some MIS ground-to-elevated and elevated-to-ground ramps in their stead, taking care to make sure they are placed correctly, as below:
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdpci%2FDPCI-03.jpg&hash=06dc2dca312fee4f0e548d0212afe6580c846253)

See the yellow lines? The direction of travel of the MIS ramps is opposite to the RHW4 pieces directly next to them. They're going the "correct" way, right-hand drivers on the right side of the junction, and left-hand drivers on the left side.

Ramps, Exits, and Entrances

Next, plop or use overrides to create a Style-B entrance ramp as close to the MIS overpasses as you can along your non-diverging freeway, in this case, an RHW10. Then join the MIS in a circle. Repeat this in the opposite quadrant.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fwww.crimsonphoenixphotography.com%2Fstorage%2Fother-stuff%2Fsc4%2Fdpci%2FDPCI-04.jpg&hash=9d389632b95a0960b92b8b9c5103cabd6c4eca99)

On the other side, plop an RHW4-dual-MIS outbound splitter connected to your MIS ramp, and join the empty MIS ramp to your main freeway. (See how that takes up almost no room? Fantastic indeed.)

Next, we bulldoze a section of the diverged RHW4. Place FLUPs OWR entrance ramps at the junction as seen below, and join them to their respective RHW4 lanes.

Next we add RHW4 Style B "Inside" entrance ramps using overrides. (There is no puzzle piece.) Start your override along the corner of the MIS ramp circle, like this:

Then complete the override by dragging-out diagonally. The starter MIS pieces at the end will be facing the wrong way. Ignore this for now; we'll fix it later.

Next, plop two road stubs on either side of the same RHW4, before the entrance ramp. This will ensure that there is room for the FLUPs pieces later. Then plop an RHW4 lane shift, and you should have this:

Now we add a FLUPs OWR exit ramp, leaving a tile of empty space for the FLUPs tile we'll place later. Add a Style A Entrance ramp after the exit.

Draw out the MIS ramps a bit, and connect them together with an RHW4-dual-MIS outbound splitter. This should fix the error that the override created before on the inside ramp.

Sidebar: In the case of an RHW6S, the dual splitter type B may look more appropriate, but using it will reduce the through traffic of the major freeway to four lanes, instead of six until it leaves the interchange. Whether or not this is acceptable is entirely up to player preference. (In general, it's not the realistic thing to do, but to each their own.)

Now to complete the RHW4 exit ramps. Start by plopping an RHW6S-to-dual-RHW4 splitter just before the lane shift:

Plop an RHW4-RHW6S transition farther back, and connect it all up, redrawing the errant 6S piece at the exit.

Final Steps: FLUPs

Plop diagonal and straight FLUPs-under-pedmall pieces in the configuration below:

There is plenty of straight space there for another FLUPs ramp and an RHW4-to-elevated transition piece, if you want to create an overpass over the major freeway instead of using FLUPs. I used FLUPs pieces because it eliminates unnecessary grade changes, which is something civil engineers try avoid in real life.

Finally, use FLUPs-under-RHW4 and FLUPs-under-RHW10 (or 4, 6, or 8; if using 6C or 8C, you must construct the flyovers mentioned above, as these aren't supported by FLUPs...I think...) to finish the FLUPs routes. If you get an error when placing the RHW10 pieces, destroy the MIS ramps, redraw the RHW10, and then place the FLUPs pieces. Replace the MIS ramps and redraw them.

You should, when all is said and done, have something like this:

I have tried a version that started from a RHW 10 and had ramps to access the center but I stumbled on a few missing pieces :

1. I missed either a diagonal or a curved transition from RHW 4 to ERHW 4.
2. A split transition from RHW10 to RHE 6(S or C) + RHW4.

I was curious about this one because of the possibility of integrating it has a central urban piece. I hope I did spark your imaginations.

I just cleared out a large plot of land in one of my test cities. I would rather start small, perhaps a 6S to 6S Pinavia or RHW-4 to RHW-4 Pinavia. If any of us are successful with reconstructing this, post it in the "Show Us Your Intersections" thread.

Luckily, there's a 10S to 6S and RHW-4 splitter in the works. There's no curved transition for RHW-4 to ERHW-4, or diagonal transition for that matter.

EDIT: I found one crucial element to be missing as well: Elevated curves for ERHW-4 and EMIS (45-deg), preferably in the FlexFly flavour...

Hello,
I've got a question. I want to make an urban highway interchange with a high capacity but with an acceptable size. I think the turbine interchange is a good option, but I don't want tunnels at the interchange because i want to use RHW6/8 and i think it drastically reduces the capacity. So is it possible to create a turbine interchange without tunnels? Or is it better to create an other interchange in a high-density urban area?

It just depends on how realistic you want your highway interchange to be. For example, using smooth curves will make the interchange look better, but will increase its size compared with standard curves.

Here's a hybrid interchange I recently built that incorporates many features from RHW 5.0. Hopefully it gives you some ideas.

All in all, you need to play around with your junction and tweak it to be what you want it to be. It takes a lot of trial and error but in the end the results can be creative and amazing.

Section 2.6: Realistic Parclo A-4 Interchange

The first tutorial in this guide since RHW 5.0's release will show you how to make a realistic parclo interchange. 5.0 has really upped the ante realism-wise, and this guide is geared to reflect that. There has never been a better time to construct realistic-looking interchanges in Simcity 4.

You will need hole digging lots for this guide. Using a slope mod is highly recommended as well.




Let's start out simple. Drag some RHW. Make sure you delete the starter pieces.
-For this guide, I am using RHW-4 with a 1 tile median. Your RHW network can be whatever size you want it to be with whatever median you want.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FPjUIA.jpg&hash=0165d1b69750bdf378a3581482ffc0da82168890)

Get the ground lifters from the hole digging lots to do their stuff. Place 1 tile away from the RHW on each side. Drag road to set up the slope.
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FHZiJo.jpg&hash=f0e4b7e1dbec3afe48280ed1a49f1e446286442c)

Demolish everything and place road stubs on your new hills.

Time to create your approach. Create a gradual assent to the top of the hills where the overpass will go. I highly recommend getting an aggressive slope mod like the RHW slope mod when you're building realistic interchanges. (I am using the bullet train slope mod here.)
(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FzHI6c.jpg&hash=b97a062ccf5af22f49be94982b54412447b481b0)

Demolish your work once again and place road stubs or drag road for one tile on either side of your RHW like so. This will be the last step in setting up your approaches and will give you an extra tile below, useful for things like accel/decel lanes or future RHW widening.

Demolish the parallel networks. Plop a pair of Avenue-MIS type B ramps in a mirrored fashion.
-These pieces are new to RHW 5.0 and will drastically improve the ascetic appeal of your interchanges!

Keep curving by dragging RHW-2 from the curves. This will properly grade the next curve.

Demolish all the RHW-2 except for 1 tile near the curves. The next step is to plop a pair of 90 degree outer MIS curves directly next to the curves you just built. See the loop starting to form?

Connect your loop to the RHW via any ramp piece you want. I am using a RHW-4 type B ramp for simplicity's sake.

Time to build the off-ramps. Two tiles away from the edges of your loop ramps, plop road stubs to level the terrain and line it up with the avenue.
-An adjustment to your avenue's slope may be required for a future intersection. I've also left a pair of extra stubs near the avenue in this example so slip lanes can be added in the future.

With your last ramps in place, your interchange is functionally complete. Use road stubs to level terrain around your interchange and demolish them when complete. This will improve the raw look of your new junction.

I've got (another) question, this time about those slope mods. In the parclo A-4 intersection, do you also make the slopes of the 'leaves' with the BTM slope mod? So do you first imitate the rhw curve with BTM, and then create the road over it? Or do you also use another slope mod?

By leaves do you mean loops? I use the RHW slope mod for my RHW networks so by default that's the slope of the loops when I drag them out.

The Bullet Train slope mod is something I use that creates an even smoother slope than the RHW slope mod. I use this for the mainline RHW lanes.

For 4+ way interchanges I like to combine interchanges. An interchange comprising of more than one type of interchange is called a meiotic interchange, and I've found they work pretty well. For your case, I'd first start with a cloverleaf + T-interchange, with the T-interchange connecting to one of the cloverleaf spurs.

Can someone please give me some tips on building the FARHW TuLEP Diamond Interchange? I normally use the SPUIs but I have a one directional/half diamond interchange that currently just connects the avenue overpass by the MIS pieces. I'd like to have something a bit more realistic that utilises the TuLEP turning lane pieces. The problem I have is that if I lay the FARHW TuLEP intersetion puzzle pieces down RHW cannot cross these tiles. Unless I'm blind I haven't found any tutorials that says how this can be done and there is no mention of using these pieces in the readme.

Thanks

The FAD puzzle pieces are to be used as any other puzzle piece. They are a self-contained intersection (No draggable component, they do NOT use WaveRIDE) and must be:
A. Placed on existing Avenue.
B. Have Avenue Type A TuLEPs connected to the inside (The side that points toward the motorway, it's the same for RHD and LHD) WITH THE EXCEPTION of the piece with only Incoming FARHW.
C. Have FARHW-4 puzzle pieces placed on whatever sides it leaves from.

I can whip up a tutorial for a FARHW TuLEP Diamond Interchange. I haven't used FAR in this guide yet, and have hardly used TuLEPs, so it will be something different for me.




Speaking about different, here is yet another example of a realistic Parclo interchange you can make with guide 2.6 (http://sc4devotion.com/forums/index.php?topic=6843.msg399433#msg399433) on the last page.
-Remember that extra tile of space left on each side of the overpass? Here it's been filled with a collector lane so both on-ramps merge before joining the highway.

I added a couple of extra ramps, so that no traffic crosses the road, while only making the junction slightly wider and somewhat longer. I'm not sure you can even call it a parclo anymore now that it has 4 loop ramps. ()what()

If it has four loops, it turns into a Cloverleaf. However, yours eliminates the weaving problem on just the major highway.

So how does one set up a cloverleaf so that it eliminates the weaving problem entirely for both highways? And would you still need a cloverleaf if the weaving problem is already that serious?
Title: Re: RHW Interchange Guide
Post by: MandelSoft on November 04, 2011, 03:10:14 PM
Well, I would turn that in a full-blown cloverleaf. In RL this would be overly expensive...

Well the way the ramps meets the minor road means that traffic leaves the minor road to join the highway  before traffic from the highway joins the minor road. So doesn't that mean the weaving is eliminated completely? Unless I've misunderstood what you meant. :-[
EDIT: You mean the weaving that'll occur as traffic passes over the bridge, right? I wasn't sure how to avoid that without making the interchange stupidly large. Besides, speeds would be lower on the minor road compared to the highway, and there's a 24 tile gap, so I don't think weaving would be a major problem on the minor road.

Just thought I'd post the same interchange, but with a slight modification:

(https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fimg818.imageshack.us%2Fimg818%2F958%2Fparclo2.jpg&hash=76fd098ac2acb71ed46f8ee43593f8245f40c607)

Now the MIS ramps are straighter, and the interchange's length has been reduced slightly. TBH I just made this interchange as an experiment to see if I could add another pair of ramps to a normal parclo A4. ;)

Put the weaving on the ramps themselves.  When I make cloverleafs, I have a 2 lane RHW and the weaving happens on that, off the flow of the highways

Hey guys, loving the RHW mod so far, my only complaint is that I now spend all my civ 4 time constructing cool looking highways, leaving me no time to actually build a city :P  Anyway, I was looking for a 4 way highway interchange that also provided access to city streets and I didn't see anything I really liked, so here is something I came up with.

The traffic flow to and out of the roundabouts isn't ideal but I preferred to save the space.  It looks pretty cool, and allows us to zone inside of the interchange.  Im hoping to get to the actual zoning phase soon so Ill post some more screens once it develops a bit.  Let me know what you think, comments suggestions critiques all welcome! :)

Looks great, I'll be watching this closely. If I were doing this, I would probably have made it even tighter, as in my typical style, and kept the roundabout connecting roads/avenues consistent, especially if there is to be zoning inside.

At present, Diagonal interchanges can only be built with RHW-4, as it's the only network that has the necessary puzzle pieces. RHW-6C will have a Ramp Interface (Diag RHW-6C Type B1) that will offer similar functionality in the next RHW.
