A Person-Based Adaptive Traffic Signal Control Method with Cooperative Transit Signal Priority

Real-time traffic signal control has long been a critical way to improve congestion. Transit Signal Priority (TSP) is seen as cost-effective reduce travel time variability. Most of the previous studies develop real-time systems on vehicle basis, which unable efficiently provide preferential treatment transit vehicles. Person-based systems, transform delay computation units from passenger, have proposed try address this limitation. However, their models, optimizing plan cycle-by-cycle, cannot rapidly respond variations. This study proposes Adaptive method with Cooperative priority (PACT). In PACT, not only do Road-Side Units (RSUs) perform optimization, but also On-Board (OBUs) in-vehicle speed advisory delays. The interaction between RSU and OBU conducted second-by-second, high adaptability Experiments are performed based real data via simulation platform SUMO. results indicate that PACT can delays both bus passengers auto at signalized intersection. Compared preoptimized plans, show each passenger vehicles experiences 33%–70% decreases in delays, 3%–29% 80%–98% when occupancy weight factor relatively large, showing potential extending performing preemption.
