基于优化的线性路口自适应交通数控研究

Research Based on Linear Adaptive Optimal Control Traffic Intersection

对线性路口提出了一种基于优化的控制模型。结合外点罚函数法和模式搜索法对路口各方向的绿灯时间进行调整。仿真研究表明提出的控制模型可以提高交叉路口的车辆通行能力,减少了车辆的延误,达到了交通信号优化的目的。

A optimization control model is proposed at linear intersection.It use exterior penalty function and pattern search algorithm to ad just the time of green light in intersection.The simulation experiment indicates that the proposed controlling model in this paper can improve the traffic capacity of intersection and reduce the delay time of vehicle and achieving the purpose that the traffic signal is optimized.
