Nice video.  And this would be the tree mod:

Digging through some old files... RHW 4.0 had some odd lane shifts:

"Update" 22: TuLEPs and Things

The Turning Lane Extension Pieces are one of the NAM's newest components with work beginning in 2009 and the first version available as part of NAM 28 in 2010. Since they're relatively young I haven't given them much treatment in my archives thread but that's about to change. 


TuLEP-like concepts have been around for a long time, but were mostly eyecandy and non-functional such as this one:

The first TuLEPs were a little clunky-looking, but they got the job done.

If you look at that picture you'll notice that one-way roads had some of the first TuLEPs, yet have not made public release even to this day. This is mostly due to configuring issues with other networks.
-I could still see this as a useful cosmetic piece in instances where lanes can both turn and go straight.

In fact TuLEPs also applied to the RHW. This was one of the principal goals of the project when it first started. The RHW TuLEPS were later overtaken by the RHW cosmetic pieces.

Eventually designs for roads with right and left turning lanes came around. These were later replaced by the slip lane pieces as these textures often required an extra or overhanging tile of networks with little or no sidewalks.

Eventually the modern TuLEPs we know today came through

Later tweaks:

The appearance of the pieces were later altered to match the markings we see post-release. Euro-style markings were also made for the first public release.

Later some more ambitious concepts were attempted including street and one-way road pieces, and even diagonal pieces such as this one:

Even with the TuLEPs selected, users are still able to make the standard road and avenue turning lanes from the RTL plugin. They are also compatible with TuLEPs such as this one so long as the intersections are also replaced.

Later NWM compatibility came, with TuLEPs being able to built in the AVE-6/TLA-7 networks. Some designs are even compatible with other NWM networks without the use of intersection puzzle pieces.

In fact, NWM-TuLEP compatibility has been awesome post-NAM 31. Using a combo of each can create some awesome-looking road networks such as this one:

All in all, TuLEPs just make your road networks look awesome. They won't do much to increase functionality and whatnot, buy they sure let you be creative and let you make your own unique designs!

That's definitely a trip down memory lane--good to see all the old TuLEP-y, slip lane-y things of yore.  There's also this blast from the past . . .

<a href="http://www.youtube.com/v/UD3JQPUrU6Y" target="_blank" class="new_win">http://www.youtube.com/v/UD3JQPUrU6Y</a>

Quite a few of these concepts are still planned to come about at some point, and it's an area that'll see some expansion with NAM 32.  It's implementation and organization that's been the sticking point all this time, and we've begun discussing a broader, more comprehensive tactic with respect to turning lanes in general, which will tie in with the developments seen in the NAM 31.x releases, which saw the auto-generated Road Turning Lanes supplanted for the semi-automatic "click-over" system.

It is worth noting that a number of the TuLEP pieces do have DIPs (Distilled Intersection Paths), taking advantage of the NAM Traffic Simulator's Intersection and Turn Capacity Effect settings to boost their capacity--the Road Type A and Avenue Type B TuLEPs fall under this category, and the Type A Avenue TuLEPs and the slip lanes re-orient the way traffic flows on tiles approaching intersections, which, in many cases, does actually factor into overall network capacity.  The same is true of the auto-generated Avenue Turning Lanes, whose days may be numbered, due to the complications they cause with Draggable Elevated Avenue Viaducts crossing other Avenues.  (The Road Turning Lanes--both the old auto ones and the new semi-auto ones--do not have a capacity boost.)

As far as RHW TuLEPs, the RHW Cosmetic Pieces (CPs), despite the fact that a number have arrows on them, are really a different animal.  The CPs are for mainline usage in access-controlled/grade-separated environments, and aren't really intended to be used as TuLEPs.  Actual RHW TuLEPs for the MIS, RHW-2, and RHW-4 are still planned for at-grade surface intersection treatments.

What about RHW-3 TuLEPs? Also, I'd like to see the slip lane in the first image...

This is mostly due to configuring issues with other networks.
-I could still see this as a useful cosmetic piece in instances where lanes can both turn and go straight.

I couldn't figure out why. All these needed were to be placed over straight away OWR, with nothing changed, because in comparison,

The RHW TuLEPS were later overtaken by the RHW cosmetic pieces

Those cosmetic RHW pieces with the arrows only go over straight away RHW-4, where OWR is not available, but still are used before ending at grade, at  the side road intersection.

In the mean time, it's a good thing OWR-3 is there when people want the MIS to have a wider exit out onto a wider side road, starting with the avenue.

TuLEP-like concepts have been around for a long time, but were mostly eyecandy and non-functional such as this one

I thought this concept implementation for the diagonal was a dragged method. And what had always caught me off guard here, was this Maxis intersection had the avenue signals afterward, despite the two tile situation.

Did you know that SC3K had slip lanes?


What's more, they didn't take up any extra tiles... I think that's why Maxis decided to put them in as there would just be empty space otherwise.

It would be awesome to see this in orth/diag intersections in SC4, made by either a drag method or a puzzle piece.

What about RHW-3 TuLEPs?

I still have these laying around, but they haven't been upgraded to P57 specs or even touched for over two years:

Just like how the ARD-3 connects directly into the Road Type A TuLEPs, the RHW-3 would connect into RHW-2 TuLEPs.

There was this, too:
