The invention provides a pedestrian crossing traffic accident risk assessment method. The method comprises the steps of obtaining a target position of a pedestrian crossing and coordinates of a target position of an upstream road section of the pedestrian crossing; acquiring test data of the real vehicle test process of the upstream road section of the pedestrian crosswalk; wherein the test data comprises positioning time, position coordinates and instantaneous speed; based on the target position of the pedestrian crossing and the coordinate of the target position of the upstream road section of the pedestrian crossing, screening target test data in the traffic safety influence range from the test data; and calculating a traffic accident risk index of the pedestrian crossing based on the target test data so as to evaluate a traffic accident risk level of the pedestrian crossing. The method is easy to operate, low in cost and high in reliability, and the traffic accident risk level of the pedestrian crosswalk of the road section can be evaluated only by collecting test data within the traffic safety influence range of the upstream road section of the pedestrian crosswalk of the road section.

    本申请提供了一种人行横道交通事故风险评估方法,包括:获取人行横道的目标位置和人行横道上游路段的目标位置的坐标;采集所述人行横道上游路段实车试验过程的试验数据;其中,所述试验数据包括:定位时间、位置坐标和瞬时速度;基于人行横道的目标位置和所述人行横道上游路段的目标位置的坐标,从所述试验数据中筛选出交通安全影响范围内的目标试验数据;基于所述目标试验数据,计算所述人行横道的交通事故风险指数,以评估所述人行横道的交通事故风险等级。所述方法易操作、成本低且可靠性高,能够仅通过采集路段人行横道上游路段交通安全影响范围内的试验数据,评估路段人行横道的交通事故风险等级。
