The invention discloses an urban intersection pedestrian-vehicle collision probability calculation method, which comprises the following steps: firstly, collecting intersection information, then calculating equivalent traffic flow density, calculating the number of arriving vehicles, and calculating the probability that an adventure pedestrian passes through an intersection and falls into an accident possible area; judging whether there is an obstacle that influence the sight of the traffic participant at the intersection, if there is, calculating an influence factor under the condition that there is the obstacle, calculating the permutation and combination of vehicles in the accident area range and the permutation and combination of vehicles in the accident possible area, and finally calculating the pedestrian-vehicle collision probability; and if there is no obstacle, calculating the permutation and combination of the vehicles in the accident area range and the permutation and combination of the vehicles in the accident possible area without calculation of the influence factor under the influence of obstacles, and finally calculating the pedestrian-vehicle collision probability.According to the invention, the intersection safety situation can be evaluated, and a decision basis is provided for intersection rectification and management.

    本发明公开了一种城市交叉路口人车碰撞概率计算方法,首先收集交叉路口信息,然后计算等量车流密度,计算到达车辆数,计算冒险型行人穿越交叉口落在事故可能区域的概率;然后判断交叉路口是否有障碍物影响交通参与者视线,有有障碍物则计算有障碍物情况下的影响因数,计算车辆在事故区域范围内的排列组合,车辆在事故可能区域内的排列组合,最后计算人车碰撞概率;无计算无障碍物影响下的影响因数,计算车辆在事故区域范围内的排列组合,车辆在事故可能区域内的排列组合,最后计算人车碰撞概率。本发明可以评价交叉路口安全现状,为交叉路口整改、管理提供决策依据。
