This map shows roundabout intersections in California. For this map, roundabouts are circular intersections with yield control on entry and parking prohibited in the intersection. All other circular intersections are considered to be traffic circles. Roundabouts are further classified as Multi-Lane, Single-Lane, and Neighborhood types. The first two categories refer to the number of circulating lanes. Neighborhood roundabouts are single-lane roundabouts with painted, instead of raised, splitter islands.To submit a roundabout location or provide comments, please contact Dave Stanek at firstname.lastname@example.org.
