Roundabout intersections have been shown to
Position 1: Transport engineers therefore increasingly recommend roundabouts as a cost-effective intervention wherever intersection safety is a concern.
Position 2: Because all vehicles travel in the same direction around a central island, the number of potential collision points is reduced from 32 to just 8.
Position 3: Studies conducted in the United States found that converting signalised intersections to roundabouts reduced fatal and injury crashes by approximately 75 percent.
Position 4: Roundabout intersections have been shown to significantly improve traffic safety compared with traditional signalised junctions.
Position 5: Furthermore, the circular geometry naturally slows approaching vehicles, which lowers both the frequency and severity of crashes.
