信息交互环境下公交信号优先控制仿真与评估

摘要
在信号控制交叉口,公交车需要与社会车辆竞争通行权.为提升公交车辆的服务质量,交通控制系统会在交叉口给予公交车辆一定的优先通行权,以保障其准点率.本研究在信息交互环境下建立单点交叉口公交车信号优先控制策略,以交叉口总体人均效益最大化为目标,兼顾公交车辆能耗、舒适性等因素,根据不同到达模式提出了公交车单点交叉口信号实时优先控制方法.并借助VISSIM仿真软件进行信号优先控制方案的验证,在不同背景交通流条件下,可以使交叉口人均延误降低13.21%,20.06%和25.27%,公交车车辆运行速度分别提升11.15%,12.16%和13.94%.
Buses usually have to compete their right of way with city cars at intersections.To promote the service quality of bus,the signal control system may provide a signal priority to bus at intersections so as to ensure the punctuality of bus.Based on the information interaction environment,this paper researches on the model of signal priority of bus in isolated intersection.This method aims at benefit maximization per capita of bus and other road users,and provides different signal priority control scenarios which are red truncation,green extension and green light phase insertion for different bus arrival modes.The lateness,energy efficiency and passengers' comfort of bus,and community vehicles' efficiency are also considered.Finally,a numerical simulation is conducted by modeling in VISSIM a representative signalized intersection with bus.The results indicate that the proposed method reduces average passenger delay by 13.21%,20.06%,25.27%and improves travel speed of bus vehicles by 11.15%,12.16%,13.94% comparing to existing signal control scenarios.
