考虑停靠时间波动的快速公交车速与路口信号协同优化
|
摘要
为了减少因公交停靠时间波动对车路协同控制造成错失绿灯或红灯时段到达的不利影响,提出了一种基于决策树模型的考虑快速公交系统(bus rapid transit,BRT)停靠时间波动的优先控制方法。该方法主要通过路段车速引导、驻站控制和信号配时调整使BRT进行进站前路段和完成上下客之后路段的两阶段决策引导。由实例可以得到:本文的控制方法相比现实中的不停车通过率提高40%、通过交叉口的平均延误降低20 s;对比不考虑停靠时间波动的不停车通过率提高20%、通过交叉口的平均延误也降低9 s。可见本文的控制方法能提高车路协同控制的可靠性。
In order to reduce the adverse effect of bus parking time fluctuation on vehicle road cooperative control,which may result in missing the green light or reaching the parking line at red light. A priority control method was proposed which based on a decision tree model and considering the bus fluctuation of dock. The method is mainly guided by the speed guidance of the road,the station control and the adjustment of the signal timing to make the BRT carry out the two stage decision guidance of the front section of the station and the following sections.Through the instance can be obtained: compared with the original control strategy,the control strategy of this article is adjusted to increase the non-stop traffic rate by 40% and the average delay through the intersection is reduced by20 seconds. In comparison with the strategy of time fluctuation optimization,the non-stop rate of this strategy is increased by 20% and the average delay time of crossing the intersection is reduced by 9 s. The results show that the control method can improve the reliability of vehicle road cooperative control.
