Roundabout

Definition:
A roundabout is an intersection of three or more roads where traffic must go around a center island, rather than traveling straight across. Entering traffic must yield to vehicles already in the roundabout.
Roundabouts reduce the likelihood and severity of collisions by reducing traffic speeds and minimizing T-bone and head-on collisions. For pedestrians, roundabout traffic comes from one direction instead of three, making it easier to see approaching cars and trucks.
Benefits:
- Reduces the likelihood and severity of collisions by promoting slower vehicle speed.
- Eliminates high severity crashes associated with left turn movements.
