Investigating the Effect of Traffic Signals on Transit Reliability

This study investigates the influence of traffic signals and Transit Signal Priority (TSP) on the evolution of transit reliability using stochastic simulations. The analyses reveal that traffic signals tend to deteriorate transit reliability and that TSP could counter the deterioration of transit reliability. The variation of dwell time and the scheduled headway are identified as two major factors that would influence the effects of traffic signals and TSP. Possible explanations are provided. These insights would shed some light on the optimization of transit service
