The invention discloses a highway tunnel secondary traffic accident monitoring and early warning method and system, and belongs to the technical field of traffic information. The method comprises the following steps: receiving accident report data, and positioning an accident area based on the accident report data; acquiring accident information of the accident area, and processing and analyzing the accident information to obtain an accident analysis result; and obtaining accident early warning information based on the accident analysis result, and updating the accident early warning information based on the real-time accident information to realize secondary traffic accident monitoring and early warning. According to the invention, based on the accident reporting information, the accident area is quickly locked, and the monitoring camera data of the accident area is called. By processing data of the monitoring camera, a high-resolution image is obtained and is used for recognizing a license plate number and a vehicle speed of a vehicle subsequently. The congestion duration is predicted, accident early warning is carried out on the rear coming vehicle through the electronic display screen in the congestion range, the vehicle slows down and moves slowly, and secondary accidents are reduced.

    本发明公开了一种高速公路隧道二次交通事故监测预警方法及系统,属于交通信息技术领域。方法包括:接收事故上报数据,基于事故上报数据进行事故区域定位;获取事故区域的事故信息,对事故信息进行处理分析,得到事故分析结果;基于事故分析结果得到事故预警信息,并基于实时的事故信息对事故预警信息进行更新,实现二次交通事故监测预警。本发明基于事故上报信息,快速锁定事故区域,调取事故区域的监控摄像头数据。通过对监控摄像头数据进行处理,得到高分辨率图像,用于后续对车辆进行车牌号以及车速进行识别。通过对拥堵时长进行预测,并通过拥堵范围内的电子显示屏对后方来车进行事故预警,减速缓行,减少二次事故的发生。
