信号灯交叉路口的实时控制模型

A Real-Time Controlling Model for Signiged-Intersections

提出了一个交叉路口交通的实时信号控制方法,它以车流密度作为控制目标来寻找最优的绿灯时间。交叉路口各进入段均装设车辆检测器,并仿真动态车流,以预测下一个信号周期内各停车线处的密度分布。具有仿真精度高,控制实时性好的特点。

This paper shows a scheme for intersection traffic real-time sign-controlling, by which the most optimized green-time can be achieved during a sign period. The optimized objection is traffic density. A loop-dector is requested for each approach,and the dynamic flow is simulated. So that it is possible for predicting the density disbrution during the next period. The model is characterized by real simulation and real-time.
