The invention discloses a channelization section lane vehicle number estimation method based on front and back snapshot data, which comprises the following steps: acquiring lane level detection data entering a channelization section in real time, and updating a corresponding channelization section lane vehicle queue according to a lane number; acquiring a signal lamp display state corresponding to each lane, acquiring whether each lane allows passage at the current moment, and when the signal lamp display state is switched, updating the current passage state of the lane in real time; acquiring lane-level detection data approaching a stop line in real time, and updating a lane vehicle queue of a corresponding channelized section according to a lane number in combination with a current traffic state of the lane; traversing all lane channelized section lane vehicle queues regularly, and calculating and outputting the number of vehicles in the channelized section lane in real time according to the queue head pointer position and the queue tail pointer position. The method makes full use of data collected by an existing red light running automatic recording system, does not depend on high-construction-cost radar/thunder vision detection equipment and the like, and can output the number of vehicles on the lane of the channelized section in real time with low cost and high reliability.
本发明公开了一种基于前后抓拍数据的渠化段车道车辆数估计方法,包括:实时获取进入渠化段车道级检测数据,根据车道号更新对应渠化段车道车辆队列;获取每条车道对应信号灯显示状态,获取各车道当前时刻是否允许通行,当信号灯显示状态切换时,实时更新车道当前通行状态;实时获取接近停止线车道级检测数据,根据车道号并结合车道当前通行状态,更新对应渠化段车道车辆队列;定时对所有车道渠化段车道车辆队列进行遍历,根据队首指针位置、队尾指针位置实时计算输出渠化段车道车辆数。本发明充分利用现有闯红灯自动记录系统采集的数据,不依赖高建设成本雷达/雷视等检测设备,可低成本、高可靠的实时输出渠化段车道车辆数。
