That's the craziest FTL I've ever seen

I love it!

but what's the point of having to wait to cross, then having to wait to go again

waste of gas and time that i would not be too happy about in reality, but interesting function in-game though

I thought that too originally until I drove through the one at Loveland, CO: https://web.archive.org/web/20100912145935/http://www.ci.loveland.co.us/publicworks/Streets/CapProjSupport/NewMadisonEisenhower.htm

The purpose of a CFI is to eliminate the problem of left turns in the intersection, as well as the risk of accidents. In many cases, there are problems with land that could skew the intersection, or the nearby businesses that getting in or out impossible with traffic timing. While there are 2 lights for a left turn, you would only stop at one of the lights, usually the back light.

Wikipedia has some good illustrations on CFIs: https://en.wikipedia.org/wiki/Continuous-flow_intersection

Well, I think you all went crazy on the NAM team!

I can watch this intersection for hours, so much so that it is impressive!

Wiimeiser · « **Reply #1284 on:** August 28, 2018, 06:54:47 PM »

So that's a continuous flow? I heard there were plans to build something like that here at one stage, but I can't seem to find them...

As far as I can remember, the setup is actually quicker for going straight or turn right (when right hand driving) because you eleminate a complete signal phase at the main intersection.
My guess is, that the left hand turners actually do not loose mutch of their time (if any), because the 2 signals for them have only two signal phases which can be managed pretty efficiently.

From an engineers point of view and looking at the simulation results, this intersections is more efficient than a normal setup. It's not very common in most parts of the world because of increased consumption of space, higher cost of construction and possible confusion of drivers unfamiliar with this type of intersections (what might actually be a very good point).

Another little something here . . . implementation-wise, this is right now set to spring forth if one immediately transitions from Avenue to Road (over two tiles) after the intersection.

Interesting design, I always wanted to have some "better" method for attaching a road at such an avenue T intersection. However, what would happen if the straight part of the road was approaching the intersection on the left tile instead of the right one?

Wiimeiser · « **Reply #1289 on:** December 26, 2018, 01:21:03 AM »

Found another issue:

No paths in LHD (don't know about RHD) and the intersection is breaking

Could this finally be flex curves for AVE 4. Looks amazing.

I don't know of any new developments flex-wise regarding the Avenue WRCs, but this is an existing piece, find it in the Road / Curves menu. Avenue pieces are towards the end of the Tab-Ring, so using Shift + Tab to scroll in reverse order makes finding them quickest. Both 45° and 90° curves exist for Avenue. Likewise FA-AVE (Fractionally Angled) pieces exist in the appropriate menu also.

Tarkus · « **Reply #1292 on:** November 08, 2019, 09:30:41 PM »

Indeed, the 45° WRC has had a FLEX version (developed by memo) for several years now.

Thought this thread deserved a bump

Nice. Though how will they work?

They will work by dragging OWR. Essentially they replace the two-lane OWR connections in these particular scenarios. If you draw OWR all the way through the intersection, it will revert to regular OWR however.

That's really some great work you're getting done here

Very nice to see this area getting some attention and also to see a new, motivated, and talented creator cutting his teeth on the NAM!

This was so sorely needed!

Terring7 · « **Reply #1299 on:** December 28, 2020, 08:38:38 AM »

This is something I always wanted and one of those things that I feel that the game should have already had them. If SimCity 3000 had those slip lanes...

...why not SimCity 4 too?

Keep up the good work, folks
