Underoverbout
This roundabout is made to deal with traffic better than a traditional roundabout. Traffic can’t go all the way around the outside of the roundabout if they want to choose the furthest exit, and instead have to go over or under the roundabout to connect with the furthest intersection.
This roundabout can only really work effectively with Traffic++, otherwise the middle will just end up a huge mess. In order to make this work effectively, add traffic lights to the cross roads in the middle.
The image shows the most effective Traffic++ setting, but for right hand drive settings this will need reversing.
