Abstract

In order to determine the sensitivity of each parameter in the car and pedestrian accident reconstruction system, nine parameters were extracted by PC-Crash software, and the orthogonal test was designed. The sensitivity ranking of parameters affecting the stop position of car and pedestrian was obtained by grey relational analysis, and according to whether the ranking results are used or not, a real car-pedestrian collision accident were reconstructed twice to verify the credibility and reliability of test results. The results show that parameters that have a significant impact on the reconstruction results are the vehicle speed, pedestrian speed, steering angle of car steering wheel during collision, the direction of the car in collision, and the friction coefficient between human body and the ground, and that by adjusting these parameters in a targeted manner, the final position error of each participant can be significantly reduced, and the speed of accident reconstruction and its fitting degree with the actual accident can be improved. © 2019 China Safety Science Journal
