This roundabout that most closely resembles the example I used. Inner ramps with split single lane highway joins I decided to add some examples of roundabouts that you can use as inspiration. Also please upvote the examples I shared, they were a lot of help to this guide.

If you have any other advice or tips for roundabouts feel free to leave them in the comments and I might even add them to the guide. While rarer, they can come in various differents shapes as you will see in the examples section. Here's a good guide on how to make perfectly round roundabouts.Also zoning near the entrances and exits is usually not a good idea either since cars turning in and out might back up in to the roundabout.congestion on the roundabout block can block traffic to any exit on the roundabout, rather than just one road. Try not to zone the actual roundabout Inside or out.6 lane roads in general usually wont do much to fix your traffic problems. On a roundabout, everyone is turning and hence only use 3 of the six lanes. This allows for a lot more creative and effective roundabout designs, including underground roundabouts! Since the 1.1.0 patch () you can build underground tunnels.Joining them, removing them, or using one way roads can ease congestion, both on nearby roundabouts and in general. A common cause of congestion is a large number of nearby intersections.Hopefully this helps you fix your congested roundabout or create a new well flowing one.
