Roundabouts are designed to improve what aspect of traffic flow?

Roundabouts are specifically designed to enhance continuous traffic flow by allowing vehicles to move through intersections without having to stop at traffic signals or stop signs. This design minimizes delays, as vehicles can yield to oncoming traffic and proceed when it is safe, promoting a smooth and uninterrupted movement of vehicles. This is particularly beneficial in reducing congestion and improving overall efficiency on the road.

In contrast, while other factors like turning movements and speed limits may be influenced by the presence of a roundabout, the primary goal remains the facilitation of continuous traffic flow. Parking availability is not a function of roundabout design, which further emphasizes the distinction between maintaining unimpeded traffic movement and managing space for parked vehicles.
