What is the purpose of a roundabout?

The purpose of a roundabout is to improve traffic flow and reduce the chance of accidents at intersections. Roundabouts are designed to keep traffic moving efficiently by allowing vehicles to continuously navigate through intersecting roads without the need for stop signs or traffic signals. This design minimizes the potential for high-speed collisions, particularly those that occur at right angles, reducing the likelihood of severe accidents. Additionally, as vehicles yield to traffic already in the roundabout, it helps to maintain a steadier flow and minimizes delays compared to conventional intersections. This effective management of traffic contributes to safer driving conditions overall.
