The invention discloses a traffic accident risk real-time assessment method and system, and relates to the technical field of traffic conflicts. The method comprises the following steps: acquiring vehicle data and road data of a road section to be evaluated, and analyzing traffic flow characteristics according to the vehicle data and the road data; determining a road section traffic safety state according to the traffic conflict condition of the to-be-evaluated road section; calculating traffic conflict risk evaluation indexes according to the traffic flow characteristics, calculating the correlation of the traffic conflict risk evaluation indexes, further calculating the importance of the indexes, carrying out sorting, and obtaining an evaluation index set according to a sorting result; constructing a traffic risk assessment model by using the evaluation index set and the road section traffic safety state; and processing the real-time data of the to-be-assessed road section by using the traffic risk assessment model to obtain a risk assessment result. According to the invention, real-time and accurate assessment of the traffic accident risk probability is realized.

    本发明公开了一种交通事故风险实时评估方法及系统,涉及交通冲突技术领域。该方法包括步骤:获取待评估路段的车辆数据和道路数据,根据车辆数据和道路数据分析交通流特性;根据待评估路段交通冲突情况确定路段交通安全状态;根据交通流特性计算交通冲突风险评价指标,计算交通冲突风险评价指标的相关性并进一步计算指标重要性进行排序,根据排序结果得到评价指标集;利用评价指标集和路段交通安全状态构建交通风险评估模型;利用交通风险评估模型对待评估路段的实时数据进行处理,得到风险评估结果。本发明实现了交通事故风险概率实时且准确的评估。
