What is the primary purpose of a traffic circle?

The primary purpose of a traffic circle is to allow easier entry and exit from multiple directions. Traffic circles, also known as roundabouts, are designed to facilitate smoother traffic flow by enabling vehicles to approach from different directions and merge into a circular roadway. This arrangement helps reduce conflict points between vehicles, as they do not have to come to a complete stop to navigate the circle, except as necessary when yielding to traffic already in the circle.

By allowing drivers to slow down as they approach rather than stopping, traffic circles can improve overall traffic safety and efficiency. Vehicles can enter and exit the circle without significant delays, even during busy times. This design minimizes the need for traffic signals or stop signs, which often contribute to stoppage and delays in conventional intersections.

While other options touch upon aspects of traffic management, they do not capture the fundamental goal of a traffic circle as effectively as promoting ease of entry and exit from multiple directions.
