  • Systems for converting an existing traffic intersection into an intersection having a roundabout, and related methods
    Patent number: 9004808
    Abstract: A system for converting an existing traffic intersection into an intersection having a roundabout traffic control feature includes a center island framework, one or more splitter island frameworks, and one or more diverter frameworks. The frameworks are secured to the road surface, and fill material is added to free spaces defined in the frameworks to thereby form a center island, one or more splitter islands, and one or more diverters. The system allows a roundabout to be implemented into an existing intersection on a temporary or semi-permanent basis, in a minimal amount of time and without requiring significant construction at the site of the intersection.
