The invention discloses an intersection self-adaptive control method in an Internet of Vehicles environment, which comprises the following steps: firstly, calculating the initial green light clearing duration of a lane based on the lane queuing length at the end of a phase red light, and then obtaining the initial green light duration of the phase; then calculating the number of vehicles arriving and joining in a queue within the phase initial green light duration based on the lane vehicle arrival rate, and recalculating the queue emptying green light duration and the phase green light duration of each lane; and finally updating the lane time headway and vehicle arrival rate parameters. The method is simple and reliable, can adapt to the traffic flow change trend in real time in the Internet of Vehicles environment, reduces unnecessary vehicle delay, and improves the traffic efficiency of the intersection.
本发明公开了一种车联网环境下的交叉口自适应控制方法,该方法首先在相位红灯结束末基于车道排队长度计算车道初始清空绿灯时长,而后得到相位初始绿灯时长;然后基于车道车辆到达率计算相位初始绿灯时长内到达并加入排队的车辆数,重新计算各车道排队清空绿灯时长及相位绿灯时长;最后更新车道车头时距和车辆到达率参数。本发明简单可靠,在车联网环境下能够实时适应交通流变化趋势,降低不必要的车辆延误,提高交叉口的通行效率。
