A roundabout is a type of circular intersection that, in the proper context, provides for safer, more efficient, and less expensive intersection operations. Roundabouts are a proven traffic calming countermeasure that help reduce the frequency of severe and fatal accidents when compared to conventional stop-controlled or signalized intersections. The key characteristics of a roundabout are:
- Counterclockwise flow around a center island
- Vehicles entering the roundabout yield to traffic already circulating in the roundabout
- Vehicles circulating in the roundabout travel at lower speeds (15 - 25 MPH)
There are over 30 roundabouts and traffic circles within the City of Tampa
