本申请公开了一种智慧隧道交通运行管控方法、设备及介质,方法包括:通过隧道中的路侧设备获取指定检测位置的隧道交通运行图像并确定隧道交通运行图像对应的车辆运行数据;针对每个车道,将车道中每个车辆的所处地理位置作为节点,将车道中任一车辆与其前一车辆之间的车距作为边构建车道的交通运行链;根据车道中任一车辆与其前一隧道出口之间的路段间距及车辆数量并基于预设的最小行车间距确定车道的车辆数量阈值;根据隧道的光亮强度数据对车道的车辆数量阈值进行补偿得到车道对应的标准交通运行链;确定交通运行链的总边数与标准交通运行链的总边数之间的差值并根据差值确定车道是否发生拥堵,实现对隧道交通运行的智慧管控。
The invention discloses a smart tunnel traffic operation management and control method and device, and a medium. The method comprises the steps of obtaining a tunnel traffic operation image of a specified detection position through a roadside device in a tunnel, and determining vehicle operation data corresponding to the tunnel traffic operation image; for each lane, taking the geographic position of each vehicle in the lane as a node, and taking the vehicle distance between any vehicle and the previous vehicle in the lane as a side to construct a traffic operation chain of the lane; determining a vehicle number threshold value of the lane based on a preset minimum driving distance according to the road section distance between any vehicle in the lane and the exit of the previous tunnel and the vehicle number; compensating a vehicle number threshold value of the lane according to the brightness intensity data of the tunnel to obtain a standard traffic operation chain corresponding to the lane; and determining a difference value between the total edge number of the traffic operation chain and the total edge number of the standard traffic operation chain, and determining whether the lane is jammed or not according to the difference value, thereby realizing intelligent management and control of tunnel traffic operation.
