| Content Summary | This paper presents a person-based traffic responsive signal control system for transit signal priority on conflicting transit routes. A mixed integer nonlinear program is formulated that minimizes the total person delay at the intersection while assigning priority to the transit vehicles based on their passenger occupancy. The mathematical formulation consists of an improvement to previous formulations in that it ensures global optimality for undersaturated traffic conditions in reasonable computational time for real-time applications. The system has been tested at a complex signalized intersection located in Athens, Greece, which is characterized by multiple bus lines traveling in conflicting directions. Testing includes cases with deterministic vehicle arrivals at the intersection as well as software in the loop simulation tests that incorporate stochasticity in the vehicles’ arrivals. The results reveal that the proposed person-based traffic responsive signal control system reduces total person delay at the intersection and effectively provides priority to transit vehicles even when perfect information about the auto and transit arrivals at the intersection is not available. | en |
