Matrix Design Group, Inc. has extensive experience in the planning, design, and construction of modern roundabouts throughout the Denver/Front Range area. The implementation of modern roundabouts in the western United States has progressed rapidly over the last decade with growing support by state and local DOTs who are beginning to favor their capacity, flexibility, and unique problem solving capabilities.
Although roundabouts are not appropriate in all locations, they do possess clear advantages over conventional intersection design in specific applications. Roundabouts can be superior in their ability to lower accident frequency and severity, process high left-turn volumes, solve unique geometric layout problems, improve safety, provide traffic calming, and create opportunities for landscape design.
Most general design and layout criteria are provided in the June 2000 Federal Highway Administration Roundabouts publication (“The Federal Guide”). Matrix uses RODEL v 1.0 roundabout software for detailed planning as well as intersection capacity and delay calculations for new roundabout design.
