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.

A system for converting an existing traffic intersection into an intersection having a roundabout traffic control feature, the intersection being formed at the junction of a plurality of road sections, each road section extending between road edges, and a road surface defined by the road sections and the intersection, the system comprising:
- a center island framework configured for positioning in a generally central location of the intersection, and for vehicle traffic to move around, the center island framework defining a plurality of center island free spaces configured to receive fill material, the center island framework including a plurality of mounting brackets configured for securing the center island framework to the road surface,
- a splitter island framework configured for positioning near the junction of a road section and the intersection, and to guide vehicle traffic from the road section into the intersection and from the intersection into the road section, the splitter island framework defining a plurality of splitter island free spaces configured to receive fill material, the splitter island framework including a plurality of mounting brackets configured for securing the splitter island framework to the surface.
A method for converting an existing traffic intersection into an intersection having a roundabout traffic control feature, the intersection being formed at the junction of a plurality of road sections, each road section extending between road edges, and a road surface defined by the road sections and the intersection, the method comprising:
- securing a center island framework to the road surface in a generally central location of the intersection, the center island framework defining a plurality of center island free spaces;
- filling the center island free spaces with fill material to form a center island;
- securing a splitter island framework to the road surface near the junction of a road section and the intersection, the splitter island framework defining a plurality of splitter island free spaces;
- and
- filling the splitter island free spaces with fill material to form a splitter island.
