交叉口配时方案实时优化与仿真系统研究

为了充分利用交叉口的时空资源,缓减拥挤,根据单交叉口的实时检测器数据,基于优化模型和仿真模型,以均衡交叉口的交通压力目标,开发了一款交叉口配时方案实时优化与仿真系统,来对配时方案中的周期、绿信比、相序进行动态优化.实测结果表明,与传统定时信号控制方式相比,优化后的交通信号配时控制效果更好,车辆平均延误时间更少.

Real-Time Optimization and Simulation System of Intersection Timing Scheme

In order to take full advantage of time and space resources of intersection and alleviate conges-tion, according to the data of a single real-time detector intersection and based on optimization and simulation models, an optimization and simulation system is developed to dynamically optimize the period, green ratio and phase sequence of timing scheme in hope of balancing the traffic pressure. The experimental results show that compared to conventional timing signal control, the proposed traffic signal timing has better control effect and less average vehicle delay.
