A Person-Based Adaptive Traffic Signal Control Method with Cooperative Transit Signal Priority (Master’s thesis)

Tag: Adaptive Signal Control, Cooperative ITS, Traffic Simulation

  • In my master’s thesis, I proposed a Person-based Adaptive traffic signal control method with Cooperative Transit signal priority (PACT). In PACT, not only do Road-Side Units (RSUs) perform signal optimization, but also On-Board Units (OBUs) provide in-vehicle speed advisory to reduce delays. The interaction between RSU and OBU is conducted second-by-second, which has high adaptability to traffic variations.

  • A study of integrating speed advisory into Transit Signal Priority (TSP) to reduce bus delays and enhance energy consumption performances. A real electric bus route in Tainan City, Taiwan is used for the case study. Intersection layout and traffic related parameters are established in microscopic traffic simulation software SUMO (Simulation of Urban Mobility) to verify the effectiveness of the proposed model.
