The invention discloses a self-adaptive traffic control method based on vehicle trajectory data, which relates to the technical field of traffic control, and comprises the following steps of: receiving traffic system log data in advance, at least comprising analyzing and acquiring signal lamp state information of a current road section; according to the signal lamp state information of the current road section, acquiring trajectory information of at least two vehicles; detecting a traffic flow arrival rate proportion in the traffic flow direction of the current road section based on the trajectory information of the two vehicle motions; and optimizing the traffic control scheme according to the obtained traffic flow arrival rate proportion. The method comprises the following steps: determining a plurality of phases in at least candidate traffic control schemes and a green time ratio corresponding to each phase. The traffic control scheme is optimized according to the current vehicle state information, the signal timing scheme of the intersection is optimized in real time, the delay of the vehicles is effectively reduced, and the delay balance of all directions of the intersection can be ensured.

    本发明公开了一种基于车辆轨迹数据的自适应交通控制方法,涉及交通控制技术领域,包括以下步骤:预先接收交通系统日志数据,其中至少包括解析获取当前路段信号灯状态信息;根据当前路段信号灯状态信息,获取至少两个车辆运动的轨迹信息;基于两个车辆运动的轨迹信息,检测当前路段交通流方向上的交通流量到达率占比;根据获取的交通流量到达率占比进行优化交通管制方案,包括:确定至少候选交通管制方案中的若干相位以及每个相位对应的绿信比。本发明根据当前车辆状态信息,进行优化交通管制方案,不仅实时优化交叉口的信号配时方案,有效地减少车辆的延误,而且还能确保交叉口各个方向的延误均衡。
