Magic Roundabout (Swindon) compromised safety. As a result, it is now planned to be converted back. Magic Roundabout (Swindon) The Magic Roundabout in Swindon, England, was constructed in 1972 and is a ring junction consisting of five mini-roundabouts arranged around a sixth central, anticlockwise roundabout. Located near the County Ground, home of Swindon Town F.C., its name comes from the popular children's television series "The Magic Roundabout". In 2009 it was voted the fourth scariest junction in Britain. The roundabout was constructed according to the design of Frank Blackmore, of the British Transport and Road Research Laboratory. Traffic flow around the larger, inner
Roundabout roundabout arms perpendicularly, well outside the circle. A pedestrian island allows pedestrians and cyclists to cross one lane at a time. The capacity of a roundabout varies based on entry angle, lane width, and the number of entry and circulating lanes. As with other types of junctions, operational performance depends heavily on the flow volumes from various approaches. A single-lane roundabout can handle approximately 20,000–26,000 vehicles per day, while a two-lane design supports 40,000 to 50,000. Under many traffic conditions, a roundabout operates with less delay than signalised or all-way stop approaches. Roundabouts do not stop all entering vehicles, reducing
