What is the purpose of a roundabout?

The purpose of a roundabout is primarily to facilitate the flow of traffic and reduce collisions. Roundabouts are designed to keep traffic moving in a circular direction, which minimizes the likelihood of high-speed collisions typically associated with traditional intersections. The design encourages slower speeds as vehicles approach and enter the roundabout, allowing for better visibility and reaction times for drivers. Additionally, roundabouts reduce the number of conflict points where vehicles would potentially collide, which contributes to overall road safety. By organizing traffic efficiently and helping to maintain a continuous flow, roundabouts can significantly decrease congestion and reduce the risk of accidents. This makes them an effective solution for managing intersections compared to other methods.
