公交车钩形转弯交叉口自适应信号控制方法

摘要
公交车钩形转弯方法可以保证禁左交叉口的公交车正常左转,对于提高交叉口通行能力、保证公交系统运行效率具有重要意义。针对该类型交叉口待行区易发生公交车排队上溯以及交叉口清空时间的浪费问题,本文基于感应信号控制逻辑,提出了三种类型检测器布设方案,建立了排队上溯检测方法、全红时间自动确定方法以及自适应信号控制流程。以沈阳市实际交叉口为例采集交通数据,在VISSIM中进行仿真评价。结果表明:在高峰期,本文所建立方法可以将车均延误降低10.8%、最大排队长度降低9.8%;在平峰期可以将车均延误降低13.1%、最大排队长度降低17.2%。
Bus hook turn method can guarantee the left turn operation of buses at the left-turn prohibition intersection.It is meaningful to improve the intersection capacity and maintain the operation efficiency of the bus system.To solve the problem of the queue bus spillovers at waiting areas and the waste of all-red clearance time at such intersection,a layout scheme of three kinds of detectors is proposed based on the actuated control logic.The queue spillover automatic detection method,the automatic determination method for all-red time and the adaptive signal control flow are developed.An intersection at Shenyang City is taken as an example and filed data are collected.Simulations and evaluations are conducted in VISSIM software.Results show that in peak time the proposed method can reduce the average vehicle delay by 10.8% and reduce the maximum queue length by 9.8%.In off-peak hour,the average vehicle delay and maximum queue length can be reduced by 13.1% and 17.2%respectively.
