roundabout exit from highway

[jeffy666 0]

Have anybody already built a highway exit shaped as a roundabout as it is made in Europe?

Is there a roundabout that acceptsboth single roads and dual lane roads?

Thanks,

I have thought about el-highway over Avenue roundabout puzzle piece, it looks possible just I haven't had time.

There are road roundabouts in the NAM already draw a 2x2 circle with the road tool, it should turn into a road roundabout

If you really want it that bad, plop an Avenue Roundabout, drag out as many intersecting avenues as you want (max 4) for one tile, then drag Ground Highways from the Avenue stubs. If you want to use Elevated Highways, you can now drag Elevated Highways to your heart's content.

I don't know if this is a safe idea, I recently replaced a avenue over interstate bridge that had ramps for an avenue roundabout instead. The problem is accidents because well over 12 hundred vehicles of all sorts, bus, freight truck, cars and the interstate merges 3 lanes to 2 right before the circle to really 1 lane, because who uses the inner part of the roundabout?

J-Dub: That is just a simple avenue roundabout where a highway ends and starts on eathier side when intersecting with a avenue.

What jeffy666 is requesting is a ROUNDABOUT INTERCHANGE (roundabout exit for highway) where the on/off ramps intersect with the interchanging road but the highway itself does not (grade separated). With a little creativity, one can construct this interchange using the in-game road networks but no actual roundabout interchange exists (like the cloverleaf)

IF you plop an Avenue Roundabout and delete the four inner tiles (as if you were going to place a filler) and then drag elevated highway over the roundabout, you get the interchange, but with a glitch which may be able to be fixed in the future.

I dunno, I can't seem to get roundabouts and offramps to even work near each other. They seem to require to be pretty far apart:

Which is really weird, because I can fill that space with road, just not the roundabout. And putting them down the other way doesn't work, either: The offramps refuse to point the right way, no matter how many times I press end.

Honestly, I don't even see how it's possible to do what he's asking with the current tools - the irony, I suppose, is that the current models work just fine for what he's asking!

PS: It seems the RHW model has an elegant solution to this...

Just need some RHW textures and a roundabout model since it obviously can work ^-^

Hmm.. Really.  Thats intresting!  I'll have to do some experimenting with that when I get some free time! 

As for the "roundabout exit for highway", Crissa, I am referring to a Roundabout Interchange rather than a roundabout intersection.

Two real life examples follow, the first one can be done by using the included highway off/on ramps in the NAM as well as the one-way (3X3 tile) roundabout.  The second one would have to be modded like the Stack interchange, which is a pain and would take forever to create.

Those are so cool IMO

where I live the traffic lights at the highway ramps cause massive amounts of traffic and in the morning it takes as long to get on the freeway as it does to take it to your final destination

But then I live in the US, and they don't build those here for some reason

What I think the NAM needs is a 6*6 roundabout where you can connect two OWRs to each side, and then in the middle could be an avenue, and then you could use big dig pieces to go underneath it.

Oh, those are awesome interchanges. The first one is possible with the current puzzle pieces - I think someone called it a 'dumbbell' interchange. The latter looks like something that would have to be modeled, but things that look awesome are usually fun to model ^-^

A dumbbell (i.e. the first picture, small roundabout on each side) is very possible given the tools we already have. You can make quite an elegant one actually, if you do it right! The large circle--which though popular in Europe and elsewhere only exist in a few places in the US, mostly in the northeast, and IMO are not as efficient as dumbbells--is technically possible with some creative use of the one-way roads, but can look a bit unelegant.

I'd show some examples that I've made but all my screenies are on a different computer.

I agree, hamsterTK, that these are much better than the standard traffic light/stop sign ramps that we have here. Fortunately, dumbbell interchanges are starting to gain favor with many state DOT's. Unfortunately, the US motoring public seems very resistant to accepting them...

cool

Those look like major traffic hazards!

Haljackey, when was that picture of Lofthouse taken? It's quite out of date, new slip roads were constructed 7 years ago. Anyway, it would be fantastic to see roundabout interchanges and 3-level-stacked-roundabouts introduced into simcity.

I think it will only be possible if you have 2 puzzle pieces, not 1, but I haven't looked at it as much as I can.
