Driving & Traffic


A roundabout is a circular intersection which connects two or more roads. Traffic circulates in a counter-clockwise direction, yielding to traffic already in the roundabout.

Roundabout Benefits

  • Safety - Fewer points of conflict and slower speeds decrease the risk of serious car crashes or injury.
  • Volume - In comparison to traffic lights, roundabouts make left hand turns more efficient.
  • Efficiency - With fewer stops and less delays than a traffic light or stop sign, roundabouts allow high volumes of traffic to travel through the area.
  • Environmental impact - Roundabouts are more environmentally friendly as they eliminate maintenance and electricity costs affiliated with traffic signals. Additionally, fewer delays help reduce the level of fuel consumption and car emissions wasted at stop lights.
