基于PC-Crash的人—车碰撞事故再现结果误差分析

Error Analysis of Reconstruction of Traffic Accidents between Pedestrian and Car on the Basis of PC-Crash

基于PC-Crash软件研究车辆与行人碰撞交通事故的三维再现结果的误差来源和影响因素。结合实际案例的模拟过程,通过不断调整参数以达到理想的准确度,分析出对模拟结果影响较大的关键参数,为以后的再现研究提供指导和借鉴,同时验证使用PC-Crash再现人车碰撞事故的可行性与准确性。

On the basis of PC-Crash,the sources and factors of error in the three-dimensional reconstruction of traffic accidents between vehicles and pedestrians are analysed.With the simulation of a real case,the key factors which affect the results greatly will be found out through continuous modifications of parameters to reach an ideal accuracy.This article can provide guidance and reference to the future research of reconstruction,and verify the feasibility and accuracy of using PC-Crash to reconstructure the accidents between vehicles and pedestrians.
