A roundabout is a circular intersection without traffic signal equipment in which traffic flows around a center island.
In Florida, over 44% of all traffic fatalities and serious injuries occur at conventional (stop & signal-controlled) intersections. Roundabouts have been proven to reduce the number of fatal and severe injury crashes by 82% over a stop-controlled intersection, and 78% over a signalized intersection. Conventional intersections have 32 vehicle and 16 pedestrian conflict points, while roundabouts have only 8 vehicle and 8 pedestrian conflict points. Because there are no crossing movements in a roundabout, severe left-turn and right-angle crashes are eliminated.
