路段人行横道二次过街感应式信号控制算法设计

Design of Pedestrian Crosswalks Twice Crossing Inductive Control Algorithm

在现有感应控制二次过街系统中,道路两边以及安全岛按钮控制多为分开控制,没有相互协调,行人在安全岛等待时间过长易导致违章过街等问题。在一次过街感应控制算法基础上,结合二次过街相关理论、机动车与行人延误机理以及行人过街信号配时理论,提出"人行绿波"协调思路,对路段二次过街感应控制算法进行设计,并应用Vissim软件进行仿真验证,结果显示设计感应控制算法能有效地降低行人和机动车延误。

To solve the problem that button controls of road sides and the safety island are mainly separate and no mutual coordination.in the pedestrian twice crossing induction control system.It makes the waiting time too long and easily cause pedestrian violation.Based on the inductive signals control algorithm of crosswalks,pedestrian crosswalks twice crossing inductive control algorithm is designed by the relative theory of twice crossing,the delay mechanism of inductive signals control between vehicles and pedestrian,the theory of signals timing while crossing and the suggested coordinate control thinking of＂the pedestrian green wave＂being integrated on the basis of it.It verifies the designed inductive control algorithm,by using Vissim traffic simulation software.According to the simulation results,the designed inductive control algorithm can effectively reduce the delay of pedestrians and vehicles.
