行人过街的上下游信号交叉口协调控制方法研究

本文以长春市亚泰大街部分路段为例,提出了行人过街的上下游信号交叉口协调控制的设计方案.利用控制优化理论,对上下游交叉口进行信号配时参数优化,通过调节交叉口间的相位差来控制车流到达人行横道的时间,从而达到在人行横道前方安装“信号灯“的作用.通过这个“虚拟信号灯“减少人车的冲突,从而达到减少车辆延误,提高行人安全的作用.最后论文利用设计方案与现有状况对比,结果显示了该设计思想的可行性和实用性.

Street Pedestrian Crossing on the Downstream Signal Coordination Itersection Control Method

This paper,taking changchun City Co.Sections of mainstreet as an example,dosigns control of the inter section of pedestrian crossing the street on the downstream signal cordination;adjusting difference to control the time of pedestrian crossing the street,consequently,signal lamp can build in the street.By using this signal lamb,the conflicts can be reduced,therefore,dallyinp over can be reduced and safety obtained.At last,the comparison between the design and present situation is introduced feasibly and practically.
