Coordinated Control Method of Bus Signal Priority and Speed Adjustment Based on Stop-Skipping

Abstract

There is an inherent coupling relationship between the time when buses arrive at the station and the time when they arrive the intersection, and it is essential to study the relationship as a whole to maximize the benefits of company operations and passenger services. In this study, a coordinated control method of signal priority and speed regulation in the stop-skipping mode at peak hours is proposed. First, the decision result of stop-skipping is obtained based on the historical passenger flow data. On this basis, the signal-priority decision is made for each vehicle in combination with the signal period and the arrival time of the intersection, and coordinated control is carried out in combination with the speed adjustment. The result of the genetic algorithm shows that cooperative control and prevention can minimize the passenger delay time and enterprise operation cost. The conclusions obtained in this research lay a theoretical foundation for company operation and signal-priority triggering mechanism.

“…Lee and Wang also proved the enhancing effect of providing advisory speed to PT vehicles in passenger delay reduction [26]. In a passenger-based ATSP developed by Zhou et al, speed adjustment of PT vehicles was deployed to minimize the PT passenger time cost caused by delay time at stops and intersections [27]. Using V2I communications, Zeng et al developed a strategy in which the data on general traffic and PT vehicle arrivals are fed into the model to minimize passenger delay at intersection level [28].…”
