What is the purpose of a traffic circle?

The purpose of a traffic circle is to manage traffic flow at intersections effectively. By design, traffic circles facilitate the continuous movement of vehicles, reducing the need for stop signs or traffic signals at intersections. This helps to decrease congestion and can enhance safety by allowing vehicles to navigate intersections without coming to a complete stop.

Traffic circles encourage drivers to yield to vehicles already in the circle, thus maintaining a smoother flow of traffic. They can also decrease the severity of accidents, as vehicles are generally moving at lower speeds when entering and exiting the circle compared to traditional intersections. In summary, traffic circles are primarily intended to improve how traffic moves through an area, making them a valuable tool in urban planning and traffic management.
