The invention relates to a saturated single-intersection bus signal control method based on a cooperative vehicle infrastructure system. A cloud processing center in the system obtains a vehicle data set on each road through a vehicle-mounted unit, and determines the road where queuing overflow occurs according to information in the data set. After receiving the queuing overflow response, the cloud processing center respectively calculates the time for the public transport vehicle closest to the intersection to arrive at the stop line of the intersection and the time for all queued non-priority phase vehicles before the threshold point to pass through the intersection so as to determine the maximum green time of the non-priority phase in the period; and timing optimization is carried out on each phase of the intersection, and induction signal control is implemented. According to the method, smooth passing of buses can be guaranteed in a saturated traffic state, the situation that social vehicles queue to pass through the intersection can be relieved to a certain extent, the congestion of the intersection is relieved, and passing efficiency of the intersection is improved.

    本发明涉及一种基于车路协同系统的饱和单路口公交信号控制方法。本系统中的云端处理中心通过车载单元获取每条道路上的车辆数据集,根据数据集中的信息,确定发生排队溢出的道路。云端处理中心接收到排队溢出响应后,分别计算此时距交叉口最近的公交车辆到达交叉口停车线的时间和在阈值点前的所有已排队的非优先相位车辆通过交叉口所需的时间,进而确定本周期非优先相位最大绿灯时间,对交叉口各相位进行配时优化,实施感应信号控制。本发明在饱和交通状态下既可以保证在公交车辆的顺畅通行,也可以在一定程度上缓解社会车辆排队通过交叉口的情况,缓解交叉口的拥堵,提高交叉口的通行效率。
