The invention provides a risk score determination method and device for a road area, electronic equipment and a medium, and belongs to the technical field of rail transit, and the method comprises the steps: carrying out the clustering of accident sample points, and obtaining a clustering category; determining a boundary region based on the sample point convex hull and the width of the target road region; when the boundary region is a rectangular region, combining the boundary region based on the region minimum distance and the linear fitting error to obtain a risk region, and when the boundary region is a circular region, taking the boundary region as the risk region; and determining a risk score of the risk region based on the unit area sample number and the unit distance sample number. According to the invention, the boundary area is determined through the sample point convex hull and the width of the target road area, so that the boundary area better fits the target road area, and the accuracy of risk area scoring is improved. By merging the boundary areas, the risk area is obtained, and the method can adapt to more road scenes.

    本发明提供一种道路区域的风险评分确定方法、装置、电子设备及介质,属于轨道交通技术领域,所述方法包括:对事故样本点进行聚类,得到聚类类别;基于样本点凸包和目标道路区域的宽度,确定边界区域;当边界区域为矩形区域时,基于区域最小距离和线性拟合误差,对边界区域进行合并,得到风险区域,当边界区域为圆形区域时,将边界区域作为风险区域;基于单位面积样本数和单位距离样本数,确定风险区域的风险评分。本发明通过样本点凸包和目标道路区域的宽度确定边界区域,使边界区域更加贴合目标道路区域,有利于提高对风险区域评分的准确性。通过对边界区域进行合并,得到风险区域,能够适应更多的道路场景。
