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 25 roundabouts and traffic circles within the City of Tampa Several additional roundabout locations are currently in the planning, concept development or final design phases including three (3) single-lane roundabouts under the 34th Street Safety Improvement Project.
