Introduction to Roundabouts Roundabouts are circular intersections designed to enhance traffic flow and improve safety. They differ significantly from traditional intersections, where vehicles stop at traffic lights or stop signs. In a roundabout, vehicles yield to those already circulating, creating a continuous flow of traffic that can effectively minimize delays and reduce congestion. This unique design is especially useful in busy urban settings like Leeds, where efficient traffic management is critical. The primary purpose of roundabouts is to facilitate smoother movements of vehicles while lowering the potential for accidents. Studies have shown that roundabouts can reduce the number of severe
