The invention discloses a method and system for evaluating side collision accident risks, and relates to the field of traffic safety evaluation. The invention discloses a method for evaluating side collision accident risks. The method comprises the following steps: calculating conflict distances between world coordinates and potential conflict point coordinates at a plurality of moments when two conflict objects pass through an intersection; calculating conflict time of the two parties of the conflict object passing through the potential conflict point coordinates according to the conflict distance and the driving speed; analyzing according to the condition that different objects preferentially pass through the potential conflict point, and calculating the collision time of multiple moments in one conflict; the minimum value of the collision time of the multiple moments is obtained and used for evaluating the side collision accident risk. According to the method, the problems that the side collision accident risk analysis of the intersection is inaccurate, the difficulty requirement is high, and time and labor are consumed during manual calculation of video track related data are solved.
本发明公开了一种评价侧撞事故风险的方法及系统,涉及交通安全评价领域。一种评价侧撞事故风险的方法,包括以下步骤:计算冲突对象双方通过交叉口时多个时刻的世界坐标与潜在冲突点坐标的冲突距离;根据冲突距离与行驶速度计算冲突对象双方通过潜在冲突点坐标的冲突时间;根据不同对象优先通过所述潜在冲突点的情况进行分析,计算一次冲突中多个时刻的碰撞时间;得到多个时刻的碰撞时间的最小值用以评价侧撞事故风险。本发明解决了人工计算视频轨迹相关数据时,对交叉口的侧撞事故风险分析不准确,难度要求高且耗时耗力的问题。
