District Department of Transportation Transit Priority Design

KAI is leading the transit signal priority system (TSP) design for up to 109 signalized intersections, along four corridors within the District. The project goals include an assessment of up to 130 intersections along four corridors, signal timing modifications for transit signal priority, and detailed design at the selected intersections for TSP equipment. The design will include signal timing modifications, traffic controller assessment and parameter modifications, priority equipment designs, and wiring.
