城市干道协调控制配时优化模型

Urban Trunk Coordinating Control Timing Optimization Model

本文从单点交叉口信号配时出发,建立干道绿波联动信号模型,应用MAXBANND模型改进最佳相位差选取方法,优化干道协调控制信号配时方案,以西安市长安路干道小寨十字和纬二街十字协调控制为仿真实验,结果表明,此干道协调化信号配时方案,可以有效减少了交叉口时空资源的浪费,提高城市道路干道通行能力和交叉口的服务水平。

This paper starts from single-point intersection signal timing, establishes the trunk green wave linkage signal model, applies the MAXBANND model to improve the optimal phase difference selection method, and optimizes the trunk coordinating control signal timing plan. Taking Xi＇an Chang＇an Road Artery Xiaozhai Cross and Weier Street cross-coordination control as simulation experiment, the results show that this road coordination signal timing scheme can effectively reduce the waste of space-time resources at intersections and improve the traffic capacity of urban roads and the service level of intersections.
