The invention relates to the technical field of traffic management, and provides an intelligent network connection traffic flow stability analysis method, which comprises the following steps of: acquiring vehicle video data of vehicles running in a traffic area by using preset camera equipment, and calculating a speed variation value and an area hysteresis coefficient of the traffic area; performing framing processing on the vehicle video data to obtain a target video frame, detecting a framing sequence corresponding to the target video frame, and calculating a vehicle acceleration corresponding to the running vehicle; extracting area features corresponding to the target video frames, positioning vehicle positions of the running vehicles in the traffic area, calculating a vehicle following brake stroke corresponding to each vehicle in the running vehicles, querying vehicle response time lag corresponding to the running vehicles, and calculating a front vehicle brake stroke corresponding to each vehicle in the running vehicles; and calculating a rear-end collision risk coefficient corresponding to each vehicle in the running vehicles, and analyzing the traffic flow stability corresponding to the traffic area. The method aims at improving the accuracy of intelligent network connection traffic flow stability analysis.

    本发明涉及交通管理技术领域,提供了一种智能网联交通流稳定性分析方法,包括:利用预设的摄像设备采集交通区域内行驶车辆的车辆视频数据,计算出交通区域的速度变异值和区域滞阻系数;对车辆视频数据进行分帧处理,得到目标视频帧,检测目标视频帧对应的分帧序列,计算行驶车辆对应的车辆加速度;提取目标视频帧对应的区域特征,定位行驶车辆在交通区域内的车辆位置,计算行驶车辆中每个车辆对应的跟车刹车行程,查询行驶车辆对应的车辆反应时滞,计算行驶车辆中每个车辆对应的前车刹车行程;计算行驶车辆中每个车辆对应的追尾风险系数,分析交通区域对应的交通流稳定性。本发明在于提高智能网联交通流稳定性分析的准确性。
