What is the primary purpose of a roundabout?

The primary purpose of a roundabout is to improve traffic flow and reduce accidents. Roundabouts are designed to enable continuous movement of vehicles through an intersection without the need for stopping, which significantly reduces delays that are common at traditional intersections controlled by traffic signals or stop signs. By allowing vehicles to yield rather than stop, roundabouts can facilitate a smoother transition of traffic from one roadway to another.

Additionally, the circular design of roundabouts reduces the likelihood of high-speed impacts that often occur in traditional intersection collisions. The geometry requires vehicles to navigate the curve at slower speeds, thereby lowering the severity of any accidents that may still occur. This design promotes safer interactions among vehicles and pedestrians alike.

While enhancing pedestrian safety and streamlining traffic flow are vital benefits, the core focus of roundabouts is their effectiveness at enhancing general traffic efficiency while contributing to fewer and less severe accidents, making them a favorable choice in many traffic management scenarios.
