The invention relates to the technical field of road early warning, in particular to an early warning method based on key operating vehicle track and ETC portal data fusion, which comprises the following steps: acquiring dynamic data and static data of key operating vehicles; based on the vehicle dynamic data, judging and outputting the driving information of the abnormal driving vehicle; according to the driving information of the abnormal driving vehicle, whether an accident occurs and accident grade information are judged through an operation driver risk evaluation model; and when the accident is judged to occur, the operation driver risk evaluation model compares and matches the accident result information with the dynamic data and the static data of the vehicle to obtain the information of the corresponding abnormal driving vehicle, and finally determines suspected accident early warning and overspeed accident early warning. According to the invention, various accidents of key operating vehicles can be pre-judged and pre-warned, and the traffic event handling efficiency is improved.
本发明涉及公路预警技术领域,具体涉及基于重点营运车辆轨迹与ETC门架数据融合的预警方法,包括获取重点营运车辆动态数据和静态数据;基于所述车辆动态数据,判断输出异常行驶车辆的行驶信息;根据异常行驶车辆的行驶信息,通过运营驾驶人风险性评估模型判断是否发生事故以及事故等级信息;当判断会发生事故时,运营驾驶人风险性评估模型将事故结果信息与车辆动态数据和静态数据比对匹配,得出对应异常行驶车辆信息后,最终确立疑似事故预警和超速事故预警。本发明实现对重点营运车辆各类事故进行预判预警,提升交通事件处置效率。
