A traffic circle is a circular intersection where several roads meet, and vehicles move around a central island in one direction to reach their desired exit. The design of a traffic circle helps improve traffic flow by reducing the need for stop signs or traffic signals, allowing cars to keep moving. Traffic circles are often used in busy areas or where roads intersect at sharp angles. They are meant to reduce the chance of accidents by controlling the speed of vehicles and providing a clear path for drivers to follow when navigating through the intersection.
