Multimodal Traffic at Isolated Signalized Intersections: New Management Strategies to Increase Capacity

New ideas are explored for managing multimodal traffic on isolated approaches to signalized intersections. Strategies are proposed that both segregate distinct modes along the approach, and more effectively resolve the disruptive capacity-reducing conflicts that arise between through moving and turning traffic traveling in adjacent lanes. This report examines the intermodal conflicts that occur at a signalized intersection, develops an analysis framework for determining the maximum flows that these intersections can serve, proposes strategies to increase these maximum flows for all modes, and applies and tests the above ideas to a real intersection approach.
