The invention discloses a traffic safety early warning analysis method and device. The method comprises the steps: obtaining the traffic data of a target region in a preset time period and the feature data of a target object; and determining a plurality of primary influence factors, a plurality of secondary influence factors and evaluation scores of the plurality of secondary influence factors on the basis of dynamic and static angles in combination with the data, then determining the importance degree of each level of influence factor, calculating to obtain a traffic safety early warning degree, and generating a traffic safety early warning analysis result. According to the invention, the problem that accurate traffic early warning prompt cannot be provided for a user in the prior art is solved, the traffic accident risk of an intersection can be evaluated more systematically, comprehensively and visually, and traffic early warning prompt can be carried out accurately; and by judging a matrix, the importance degree of each index is determined, the safety risk of the intersection can be quantitatively represented, and accurate risk early warning can be carried out on pedestrians and vehicles on branches.
本发明公开了一种交通安全预警分析方法及装置,其中,该方法包括:获取目标区域在预设时间段的交通数据及目标对象的特征数据;基于动态静态角度,结合上述数据,确定多个一级影响因子、多个二级影响因子及多个二级影响因子的评价分数,继而确定各级影响因子的重要程度,计算得到交通安全预警度,生成交通安全预警分析结果。通过实施本发明,解决了现有技术中存在的无法为用户提供准确的交通预警提示问题,能够更加系统、全面、直观地评价路口的交通事故风险,精准进行交通预警提示;通过判断矩阵,明确各指标重要程度,可以对路口安全风险进行定量化表征,进而对支路行人和车辆进行准确风险预警。
