公交信号优先控制的应用研究

公交信号优先以公交车流为控制目标,通过选择交通控制策略和设置相关参数,控制交通信号灯,减少公交车辆在路口的等待时间,提高公交车辆的运行优先级。详细介绍了公共交通信息与优先系统PTIPS的系统框架、通讯方式、主要功能、控制策略,并且分两类:基于信息反馈的动态优先;基于历史数据调查研究以及各种算法、理论推导的静态优先。详细阐述了各种控制策略的原理和适用情况。最后采用浦东张江有轨电车工程的实际应用情况作为示例,以动态优先策略为基点,各种检测设备的信息反馈为基础,较好地实现针对单辆有轨电车的优先放行。

The Application of Transit Signal Priority in Zhangjiang

The goal of Transit Signal Priority is to control the Bus flow by choosing the traffic controlling strategies and set the parameters of the systems. It can switch the traffic lights and reduce the waiting time that spends when they cross a crossroad.The algorithm will promote the priorities of buses when the situations of the traffic are not so good.This paper introduces the frame of the system of PTIPS,the modes of communication,the main function of the system and the controlling strategies.There are two c...
