主辅灯信号系统的辅灯信号控制方法的研究

The Method of the Auxiliary Light Signal Control in The Main-auxiliary Light Signal System

城市道路人行横道是除交叉口外的重要的交通冲突区域,协调人行横道处的机动车流和行人过街等非机动车流的行为冲突具有重要意义。针对目前人行横道行人过街组织方式存在的弊端,采用基于行人过街请求的主辅灯信号联动控制策略控制人行横道交通行为。首先提出了主辅灯信号系统的辅灯控制方法原理;其次研究基于行人过街请求和主灯控制器信号配时的信号控制策略,实现满足行人过街请求前提下的车辆通行最优化控制方法;最后设计一种行人过节请求的辅灯控制器,通过设计相应功能模块,实现辅灯信号控制策略。模拟实验方案结果表明:在不同信号状态下触发行人过街请求信息,辅灯控制策略模型能够准确输出的辅灯信号的配时方案,在实施该信号控制策略后,车辆通过交叉口和辅灯人行横道区域的通行效率明显增加。

he pedestrian crossing is the important Traffic conflict area besides the intersection, the method of coordinating the traffic conflict of motor and non-motor has Important significance. In view of the method of organizing pedestrian to cross street is Imperfect now, we use the main-auxiliary light signal linkage strategy base on request of pedestrians crossing street. firstly, this paper propose a method of the auxiliary light signal control in Main-Auxiliary light signal system ;then researching the control strategy of the auxiliary light base on the request of pedestrians crossing street to allow the most vehicle passing the road; designing a auxiliary light signal controller which contain several module to achieve to generate the signal timing Scheme. the result of the Simulation Experiment demonstrates that the control model of the auxiliary light signal could generate the signal timing Scheme Accurately, the vehicle Traffic efficiency has been Improved between area of the intersection and pedestrian crossing.
