摘　　要：为实现城市道路资源优化配置,在LabVIEW软件平台上对基于独立交叉口的自适应交通控制系统进行了仿真研究。该系统以交通信号灯对车辆的行与停进行管制,同时根据各路段实时车流量与道路饱和率进行自适应变化,调整交通信号灯的运行周期,并修正各交通方向上绿信比,以提高交叉口单位时间通车率。测试结果表明,该仿真系统运行稳定,满足仿真研究的设计需求,可以为城市交通监测控制提供理论参考和城市交通组织管理提供决策依据。To achieve the optimal allocation of urban road resources,a simulation research of self-adaptive traffic control system based on independent intersections in the LabVIEW software platform has been carried out.This system controls run and stop of the vehicle by its traffic lights ,makes self-adaptive changes according to current traffic flow and saturation rate of various roads,adjusts the running cycle of traffic lights,and corrects green light ratios of all directions,improves the efficiency of the intersection in unit time.Test results show that,this simulation system runs stability,achieves the design requirement of the simulation research,can provide theoretical references to urban traffic monitoring and controlling and decision bases to urban transport organization and management.
