The invention discloses a mountain road driving safety early warning method based on edge-cloud collaboration, which comprises the following steps of: dividing a road into a plurality of road section intervals, and obtaining the position data, historical accident data and historical risk index data of each road section interval; according to the position data, the historical accident data and the historical risk index data, constructing a road section driving risk assessment model of each road section interval; acquiring real-time position information and real-time risk index data of a vehicle; acquiring a road section driving risk assessment model of the current road section according to the real-time position information; inputting the real-time risk index data into the road section driving risk assessment model of the current road section to obtain a real-time driving risk accident rate; and generating an early warning instruction according to the real-time driving risk accident rate. The mountain road risk source is fully considered, the driver and vehicle risk data are considered at the same time, a closed-loop mountain road risk assessment system is formed, and the operability is high.

    本发明公开了一种基于边云协同的山区公路行车安全预警方法,包括如下步骤:将道路划分为多个路段区间,获取每个路段区间的位置数据、历史事故数据和历史风险指标数据;根据所述位置数据、历史事故数据和历史风险指标数据,构建每个路段区间的路段行车风险评估模型;获取车辆的实时位置信息和实时风险指标数据;根据所述实时位置信息,获取当前路段的路段行车风险评估模型;将所述实时风险指标数据输入当前路段的路段行车风险评估模型,得到实时行车风险事故率;根据所述实时行车风险事故率生成预警指令;本申请充分考虑了山区公路风险源,同时考虑了驾驶员及车辆风险数据,形成了闭环的山区公路风险评估体系,可操作性强。
