What is the purpose of a roundabout?

The primary purpose of a roundabout is to control traffic at intersections. By design, roundabouts facilitate a circular flow of vehicles, which helps to reduce the likelihood of severe accidents that are more common at traditional intersections. They allow for continuous movement of traffic, requiring vehicles to yield to those already in the roundabout, which effectively lowers speeds and provides a safer environment for both drivers and pedestrians.

In contrast to this, while roundabouts can contribute to speeding up traffic flow by minimizing stop-and-go scenarios found in traditional intersections, their main function remains traffic control. They do not serve as rest stops, as these are typically designated areas for drivers to pause and take breaks. Additionally, while pedestrians are accommodated in the design of roundabouts, the main intent is not to provide direction for them but rather to maintain safe passage while vehicles maintain their flow.
