Use of Innovative Intersection Designs for Improving Mobility and Reducing Roadway Traffic Congestion

Traffic engineers, their partner agencies, and developers increasingly have to consider the use of innovative intersection designs, including single-point urban interchanges, Michigan U, Super Streets, continuous flow intersections, to mitigate the congestion problems at conventional intersections. An innovative intersection is generally defined as any at-grade design concept that is able to reduce the number of traffic signal phases at the main intersection, thereby increasing the efficiency and capacity of the intersection and improving progression at the corridors. It is important to understand the applicable conditions for such intersection designs and how they are performing in terms of operations, safety, and their general public acceptance. The proposed research project is to systematically investigate the operational and design issues in the implementation of such innovative designs and to evaluate the operational benefits of these intersection designs. The outcome of the project will provide tools and guidelines for appropriately selecting the right locations and cost-effectively implementing of different types of innovative intersection designs.
