Why are roundabouts designed?

Roundabouts are specifically designed to improve traffic flow and reduce collisions. The circular design allows vehicles to move continuously and at slower speeds, which minimizes the potential for severe accidents. Unlike traditional intersections, where vehicles may come to a complete stop and have to navigate sharp turns, roundabouts require vehicles to yield to traffic already circulating, leading to a smoother and more efficient flow of vehicles.

This design reduces the conflict points between vehicles, as traffic moves in a single direction around the central island, significantly lowering the likelihood of head-on and T-bone collisions, which are common at traditional intersections. The result is a safer environment for both vehicles and pedestrians, thereby improving overall traffic safety and efficiency.

Considering the other options, while reducing traffic delays at signals and the aesthetic appeal of roundabouts may be secondary benefits, their primary function is centered on enhancing traffic flow and safety rather than serving as tourist attractions or increasing property values.
