Roundabouts have been shown to improve

Position 1: These findings have prompted transport authorities worldwide to prioritise roundabout construction in new road infrastructure projects.

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 76 percent.

Position 4: Roundabouts have been shown to improve traffic safety significantly compared with traditional signalised intersections.

Position 5: Furthermore, the circular geometry naturally slows vehicle speeds, which lowers both the frequency and the severity of crashes that do occur.
