摘要
路段行人过街信号控制已成为城市交通信号控制不可或缺的环节,如何充分利用好路段行人过街信号灯,在保障行人过街安全前提下最大限度降低信号灯对路段机动车通行能力和通行效率的负面影响.本文通过对不同类型行人过街信号控制方式的分析,提出了干线协调中的行人固定式请求控制算法流程,总结了城市混合交通环境下行人一次过街、行人二次过街及行人二次连续过街与上下游路口协调控制的设计,缓解了行人过街等候时间和机动车通行效率相冲突的问题.
Pedestrian signal control on roadway segments has become an indispensable part of urban traffic signal control.It’s big challenge to make full use of the signal lights of pedestrian crossing and reduce the adverse impact of it on traffic capacity and operation efficiency without affecting the safety of pedestrian crossing if possible.Based on the analysis of different types of pedestrian crossing signal control methods,this paper puts forward the pedestrian fixed request control algorithms which are used in coordination signal control for arterial roads,and summarizes the design scheme of one-step pedestrian crossing,two-step pedestrian crossing,and two-step continuous pedestrian crossing with respect to the upstream and downstream intersections and crossings under urban mixed traffic environment.These designs are considered to alleviate the conflict between waiting time of pedestrian crossing and vehicle traffic efficiency.
