What is the purpose of a roundabout?

The primary purpose of a roundabout is to manage traffic flow at intersections. Roundabouts are designed to improve safety and efficiency by allowing vehicles to move continuously around a central island rather than stopping at traffic signals or stop signs. They encourage lower speeds, reduce the likelihood of high-speed collisions, and facilitate smoother transitions between different directions of travel. By allowing vehicles to yield to traffic already in the roundabout rather than stopping and waiting for a green light, they help to minimize delays and keep traffic moving more steadily, which is particularly beneficial in heavily trafficked areas. This design aims to create a safer environment for all road users, including drivers, cyclists, and pedestrians.
