Modeling Impact of Near-Side Bus Stop on Transit Delays at Transit Signal Priority Enabled Intersections

Transit Signal Priority (TSP) changes traffic signals for incoming transit vehicles to facilitate their movements through intersections. Many researchers have observed that near-side bus stop with upstream detection decreases transit benefits from TSP. However, little theoretical work has been done for estimating transit vehicle delay introduced by near-side bus stops. In this research, the interactions between transit vehicles and traffic signals under certain TSP configurations are studied. A theoretical model is developed to estimate the corresponding delays introduced by a near-side bus stop at TSP-enabled intersections. Simulation tests are conducted to verify the modeling results. The model and simulation results indicate that TSP may actually increase transit delays under certain conditions at intersections with near-side bus stops. The model also reveals that green extension may not be a suitable TSP treatment at intersections with a near-side bus stop because it may significantly increase transit vehicle delays under certain conditions.
