摘要
由于城市人口增多,车辆堵塞的问题愈加严重,需要研究出有效的城市停车标志交叉口交通信号灯智能控制方法,针对当前方法仍然存在的车辆堵塞问题,提出了一种基于对称性换道规则的信号灯智能控制方法。上述方法利用停车标志交叉口交通信号灯变换时间的取值对车流密度、车流速度和车流流量的函数进行控制,在控制上述函数的同时建立了城市停车标志交叉口交通信号灯模型,将交通信号灯模型按照对称性换道条件进行换道操作,通过信号灯信号更新的方法,实现对城市停车标志交叉口交通信号灯的智能控制。仿真结果表明,提出的基于对称性换道规则的信号灯智能控制方法极大的缓解了城市车辆的交通堵塞问题。
With the increase of urban population, the problem about vehicle congestion becomes more serious. It is necessary to research an effective method to intelligently control the traffic light at intersection with urban parking sign. This paper focuses on a method to intelligently control signals based on symmetrical lane-change rule. The above method used the value of conversion time of traffic light at the intersection with stop sign to control the functions of vehicle density, traffic velocities and vehicle flow. Moreover, this method established a model of traffic light at the intersection with urban parking sign while controlling above functions, and then the method changed the lane of model of traffic signal based on the condition of symmetrical lane change. Finally, we realized the intelligent control for traffic signal at the intersections with urban parking sign through updating signal. Simulation results show that the intelligent control method of signal based on symmetrical lane-changing rule greatly ease the traffic pressure.
