NNS-Roundabout Exit
NNS-Roundabout Exit by ZEF STAR
Pretty common sense roundabout interchange. Good for medium density traffic flow, but tends to suffer with higher loads.
Important with roundabouts: Even though I’ve only added a few units of road on the end, you must make sure that traffic has space between the roundabout and the next intersection. Lots of people throw these guys right up against intersections with signals. This kills the roundabout, at that point you might as well not use one.
