Bus Punctuality Control Model Based on the Phase Margin Time at Intersections

摘要:

为了提高公交准点率，提出了一种利用上游交叉口信号配时方案调控公交车辆到达下游公交站点时刻的方法.通过引入交叉口相位裕量时间，调节公交车辆实际与计划驶离上游交叉口之间的时间偏差，建立了基于交叉口相位裕量时间的公交准点控制模型；通过优化干线交叉口的公共信号周期和相位差，得到了面向准点率控制的公交计划到站时刻表制定方法.算例仿真实验结果表明，该控制模型可以提升公交到站的准点性，所确定的公交时刻表方案具有较好的控制效果.

Abstract:

To improve the bus punctuality rate, this study presented a method to control bus arrival time to the downstream bus stop by optimizing the upstream intersection signal timing scheme. The deviation between bus actual and scheduled departure time at the upstream signalized intersection was adjusted by introducing the intersection phase margin time, and the bus punctuality control model based on the phase margin time was established. The bus arrival scheduled timetable was generated via a comprehensive optimization of common cycle length and offsets along the artery. The simulation results show that the developed control model can guarantee the bus punctuality, and the bus timetable can get a good control effect.
