车流量的的交通信号灯控制模式和仿真

The Traffic of the Traffic Lights Control Model and Simulation

在使用压力传感器实时采集交通路口各方向车流量数据的基础上,提出了一套自动周期自动交通灯比例时长和固定周期自动交通灯比例时长相结合的智能交通控制方案,即根据车流量的实际情况,自动调节信号周期和红绿灯配时比例,以尽量减少道路交通路口的车辆滞留,实现交通灯的智能化控制;使用MATLAB编制了仿真程序,对方案进行了仿真实验,结果显示:平均车辆延误时间比传统的固定配时方案以及采用模糊算法或改进的模糊算法方案都低。该方案不受时间和地域影响,对所有交通路口均能达到最优化的交通灯控制。

Based on the traffic flow data collected by the pressure sensor, we presented a set of intelligent traffic light control scheme,that is,according to the actual traffic sittution,it can adjust the signal cycle and traf^c light proportion automatically to minimize the vehicles stay in the intersrtyion and carry the point of intelligent traf^c control. A maflab simulation code has been developed to calculate the average delay time of this scheme.results show thar the average delay time is not only smaller than the traditional fixed-time scheme,and also smaller than the scheme using fuzzy algorithm or improved fuzzy algorithm. Moreover, this scheme can be used in all traffic seeyion and all traffic situations.
