基于Synchro的绿波协调与行人二次过街协同控制

摘要

为了达到同时降低主干道上机动车与次干道上行人延误的目的，提出了一种基于Synchro的绿波协调与行人二次过街的协同控制方式：首先，在理论上分析了交叉口处机动车的非对称放行与行人二次过街的相位设置；其次，建立了机动车、行人的时间延误模型，并且结合Synchro的功能提出了控制参数的优化方法及流程。以秦皇岛市河北大街西段为例进行了仿真实验，在交叉口间距不等、双向流量不均匀、行人过街距离较长的条件下，本方法较传统方法能进一步提高对机动车与行人的服务水平。%To reduce the delay of vehicles and pedestrians simultaneously,a synergic control method of green wave coordinate control is proposed.This method of asymmetric signal phase setting for vehicles can correspond to the behavior of the pedestrian twice crossing at intersections.A model is built to evaluate the time delay of vehicles and pedestrians,and to optimize the control parameters in the model by synchro.The western section of Hebei avenue of Qinhuangdao is an example in simulation experiment.The result shows that on the general condition the new method can improve the level of service of vehicles and pedestrians simultaneously better than the traditional method.
