Plan your routes accordingly to avoid delays.

About Roundabouts:

The modern roundabout is characterized by the following basic principles:

  • Generally circular shape with counterclockwise traffic flow
  • Yield-at-Entry - Vehicles approaching the roundabout must wait for a gap in the circulating flow, or yield, before entering the circle
  • Slow speed environment - Through geometric curvature and deflection, the traffic is directed or channeled to the right with a curved entry path into the circulatory roadway
  • It can be more than one circulating lane
  • In some cases, right turns can bypass the circulating roadway
  • Safely accommodates cyclists and pedestrians by providing a low-speed environment
