为了进一步验证基于Pc-Crash的车人碰撞事故再现仿真的有效性,针对一例典型的具有视频监控的小汽车与行人的碰撞事故案例,分别采用Pc-Crash软件仿真和视频图像测量技术进行车速计算,所获得的事故车辆车速基本一致。结果表明,基于Pc-Crash的车人碰撞事故再现仿真结果是可靠的、有效的;当事故现场痕迹信息不足时,Pc-Crash依然可以充分依靠事故现场所能取得的有限的痕迹信息,获得一个较为可信的结果,证明该软件具有良好的实用性。
To further test the effectiveness of the method used to reconstruct a vehicle-pedestrian accident scene based on Pc-Crash simulation, a real vehicle-pedestrian accident case recorded by freeway surveillance video was introduced and the crash speed was estimated. The speed of the vehicle was calculated by PC-Crash simulation and video image processing technique respectively. The results show that the speed of the vehicle simulated by PC-Crash was consistent with the speed calculated by the video image processing technique. The reliability and feasibility of the vehicle-pedestrian collision reconstruction was further veriifed. A reliable result could also be obtained by Pc-Crash simulation when the trace information was inadequate. This paper demonstrates that the accident scene reconstruction based on the Pc-Crash simulation is instructive for accident investigation.
