摘　　要：汽车安全性受人员、车辆和环境等因素的影响,导致交通事故的成因复杂,给交警事故定责增加诸多困难。为了给事故调查分析提供技术支撑,基于Unreal Engine 4(UE4)开源仿真引擎,开发了交通事故再现仿真平台。平台基于惯性导航原理,建立事故轨迹数学模型,并结合事故车辆汽车事件数据记录系统(Event Data Recorder,EDR)中存储的事故数据,实现事故过程再现仿真。结果表明,交通事故再现仿真平台通过读取汽车事件数据记录系统数据,能够快速实现交通事故再现仿真,为交通事故再现分析提供了有利的仿真工具。Traffic accidents are influenced by various factors including personnel,vehicles,and the environment,resulting in complex causes and challenges in determining accident responsibility for traffic police.To support accident investigation and analysis,this study developed a traffic accident simulation platform using the Unreal Engine 4(UE4)open-source simulation engine.By employing the principles of inertial navigation,the platform establishes a mathematical model for accident trajectories and integrates accident data stored in the Event Data Recorder(EDR)of the involved vehicles to reproduce and simulate the accident process.The results demonstrate that the traffic accident reproduction simulation platform efficiently reproduces and simulates traffic accidents by extracting data from the vehicle's event data recording system,providing a valuable tool for accident reconstruction analysis.
