Modern Roundabout

Design Description

All thru and turning traffic from all intersection approaches circulate within the two-lane Roundabout roadway. Modern roundabout designs with smaller roundabout island diameters require all entering vehicles to yield to circulating flows, and often right-turns are channelized so that they are not part of the circulating flow.
