Which highway interchange is the most efficient?

[Edgelord69]

There are many interchanges in the workshop, what's the difference other than appearence?

[bradybrklyn]

Most efficient? I don't think anyone could say that, but this one works like a charm:

The best highway interchange is an all highway interchange (on/off ramps are slow). This was the only one I found near release day, it's probably not the best, but works wonderfully.

I have little or no issue with this one. http://steamcommunity.com/sharedfiles/filedetails/?id=406146329&searchtext=

That looks nice. It seems all highway and much smoother flowing than my cheesy all highway clover. But it looks enormous. May have a few more issues ploping it in rough terrain.

I'll have to test it out. subscribed!

It will depend on the situation- amount of traffic flowing through the interchange, buildings nearby eg a station/sports stadium or residential/commercial/industrial zone. Bus routes airport traffic etc. What works in one position might not work in another. Being a Brit I tend to be heavily influenced by the ubiquitous roundabout- I kinda freak out at the overly complex over engineered north american style interchanges that eat up lots of space and lots of concrete & maintainence for little gain

lol, I thought the opposite true. I find roundabouts clog up easy from many intersections on one small wheel. I use highway roundabouts only, and it still does it.

In the end, the basic cheesy roads in the game work fine once the area matures. These fancy workarounds are only needed in freshly created zones. Once they've matured you can replace them with simple roads.

[NoirMoutton]

It's all relative- size of roundabout/number of lanes/traffic lights/no lights/ no of roads the roundabout serves and of course density of traffic & road priority. Seen a lot of crazy 2way roundabouts in some builds that would cause utter chaos in the real world. If you live in a country where roundabouts are rarely used then the correct usage/prorities might be lost on you. It should be noted that ALL road junctions/roundabouts/interchanges/entry/exit points and bridges are an impediment to traffic flow and will result in pinch points no matter how well they're designed!

[MarkJohnson]

We have roundabouts in our area. I see one one purpose for them and that is to keep traffic from stopping.

no left turns are possible and they are always one-way otherwise they wouldn't work.

but they don't seem to work with heavy traffic as the impedance catches up eventually. but they are better than stop signs or traffic lights and they make you stop and wait and then backups get worse.

That's why I just extend highways through my city with lots of exits.

But roundabouts are perfect for light traffic as you don't need to stop. They are good for gas mileage and travel time as well.

I made this one, it is really, really big interchange, but it works!

Funny enough, I finished uploading this today :D Most of the important stuff is in the description. On personal note, I think it looks the best, especially when it's active.

[Vortigern]

I try to keep interchanges as small as possible. I've built quite a few and explored many options.

I've noticed that for some reason traffic tends to all run in the 'slow' lane to the point of jamming before spreading to the other lanes, so traffic joining into that jammed lane causes even more issues.

What I've found is that, without lane management mods, for maximum efficiency it's actually best to have traffic joining and leaving a highway from/to what we think of as the 'fast' lane.

Try this for a T Junction: http://steamcommunity.com/sharedfiles/filedetails/?id=650400376
This for an off-ramp: http://steamcommunity.com/sharedfiles/filedetails/?id=650400072
Or this for a cross intersection of 2 highways: http://steamcommunity.com/sharedfiles/filedetails/?id=666227522

I have several others that may be of use, please check out my Workshop page: http://steamcommunity.com/profiles/76561198025645634/myworkshopfiles

The Cletic knot looks brilliant! By the way, I noticed something... Traffic in C:S is just following real life traffic laws to a fault. These traffic nightmares are what would happen if everybody followed the road laws to the letter!

[lozacenz]

The basics of roundabouts are this:
you use them when all incoming roads see about equal amounts of traffic (can't recall how to explain why that is the case, but it is.), and the more traffic goes through them at a time the bigger the circle must be.

mods allowing finer control over lanes and road types let you set up some fun things to make them even better, too. spirals.

Use a lifted roundabout on top of the ongoing highway. Roundabouts are the bomb. (See my CS screenshots)
