What is the purpose of a traffic circle?

The purpose of a traffic circle is primarily to improve the flow of traffic and reduce collisions. Traffic circles, also known as roundabouts, are designed to manage the movement of vehicles at intersections by allowing continuous flow of traffic without the need for stop signs or traffic signals. This design helps to minimize the number of conflict points where accidents can occur, as vehicles within the circle have the right of way over those entering it.

By slowing down the traffic speeds and encouraging a smoother merging of vehicles, traffic circles drastically reduce the likelihood of high-speed collisions typically seen at traditional intersections. They also help to keep vehicles moving, which can reduce congestion, as drivers do not have to come to a complete stop unless there are other vehicles in the circle. Overall, the design of traffic circles plays a significant role in enhancing road safety and efficiency.
