Transit Signal Priority Optimization under Arterial Signal Coordinated Control Conditions

Arterial signal coordinated control system and transit signal priority strategy are widely used for decreasing delay and improving the level of service in the urban areas, therefore, transit signal priority (TSP) optimization under arterial coordinated control condition needs to be focused on for improving urban traffic efficiency. This paper develops an arterial signal coordinated control method regarding TSP scenarios considering passenger delay and transit schedule adherence simultaneously, and a passenger-based MAXBAND graphic method is proposed to a generate coordinated control plan. Consequently, a test arterial segment of Nanjing (in China) is simulated by the VISSIM software platform to evaluate and analyze the performance of the proposed optimization method in decreasing delay and improving system reliability. The results illustrate that the proposed optimization model presents promising outcomes in transit signal priority under signal coordinated control conditions compared with traditional coordinated optimization methods.
