Inverted Roundabout

A roundabout with onramps on the outside and offramps on the inside, to reduce traffic weaving. Should have significantly better traffic flow than a normal roundabout as traffic taking the 2nd exit can leave immediately and traffic taking the 3rd exit only moves one quarter of the way around before reaching an offramp. 1st exit uses slip lanes. TMPE may make the traffic flow even better, use it to prevent traffic from crossing over cars taking the 2nd exit. This would effectively make it behave like a mini pinavia interchange.

Designed for 6-lane one-way roads, only 1 layer high and less than 30 x 30 cells
