The invention relates to the field of traffic transportation, and provides a road risk assessment method and device, electronic equipment and a storage medium, and the method comprises the steps: segmenting a plurality of to-be-assessed road segments with unique road segment identifiers, and obtaining a plurality of basic road segments with basic road segment labels; counting vehicle event indexes of each basic road section based on the vehicle event information; determining a risk coefficient of each basic road section based on the vehicle event index of each basic road section; and after the basic road sections are combined to obtain a plurality of continuous road sections, the risk degree of each continuous road section is determined. Different unique road section identifiers are set for roads in different directions, and the risk degrees of the roads in different directions in the same area are calculated, so that the risk assessment accuracy is improved; the risk coefficients of the basic road sections obtained through segmentation are calculated and then combined, the risk coefficients of the continuous road sections are obtained, compared with a risk assessment method of an area block, the risk continuity is better, the continuous geographic road sections can be displayed on a map, and the risk road sections are visually displayed.
本发明涉及交通运输领域,提供一种道路风险评估方法、装置、电子设备及存储介质,对多个具有路段唯一标识的待评估路段进行分段,得到具有基础路段标签的多个基础路段;基于车辆事件信息,统计各基础路段的车辆事件指标;基于各基础路段的车辆事件指标,确定各基础路段的风险系数;对各基础路段进行合并得到多个连续路段后,确定各连续路段的风险程度。通过给不同方向的道路设置不同的路段唯一标识,计算相同区域内不同方向的道路的风险程度,提高风险评估的精确度;对分段得到的基础路段计算风险系数后进行合并,得到连续路段的风险系数,相比于区域块的风险评估方法,风险连续性更好,并且可以以连续的地理路段展示在地图上,直观显示风险路段。
