The primary purpose of a roundabout is to improve traffic flow and decrease accidents. Roundabouts are designed to keep vehicles moving efficiently by reducing the number of stop-and-go situations that often occur at traditional intersections. They promote continuous traffic movement, which helps to minimize delays and can lead to lower congestion levels.

Additionally, roundabouts enhance safety for drivers and pedestrians. The design of a roundabout reduces the likelihood of high-speed collisions, as vehicles must slow down to navigate the circular path. This results in fewer severe accidents compared to traditional intersection layouts. Overall, the implementation of roundabouts aims to create a more streamlined and safer driving experience for all road users.
