摘　　要：车人碰撞事故再现已成为国内外研究热点,提高结果可信性为事故再现的核心。根据事故再现所需痕迹将再现方法分为6类,即"行人抛距"、"车辆制动距离"、"行人损伤"、"车辆变形"、"其他"以及"仿真"。通过分析各类方法的优缺点,提出可综合利用这些方法获得客观、可信的事故再现结果。然后探讨提高车人碰撞事故再现结果可信性的新发展方向:开发国产、高精度的事故再现软件,研究事故再现结果的不确定性问题,以及研究痕迹间关系在事故再现中的应用。而其中仿真所得事故再现结果的不确定性问题、车人碰撞事故再现区间不确定优化方法以及事故现场痕迹间关系为值得期待的新研究内容。Vehicle-pedestrian accident reconstruction, the crux of which is to enhance the reliability of reconstruction results, is a research hotspot in accident reconstruction field now. All methods in vehiclepedestrian accident reconstruction were divided into six categories, which are “Throw Distance”, “Braking Distance”, “Pedestrian Injury”, “Vehicle Deformation”, “Other Traces” and “Simulation”. The advantages and disadvantages of all these categories were analyzed. Further more, an idea to use all cate- gories to obtain reliable results was given. Finally, in order to enhance the reliability of reconstruction resuits, the development direction of vehicle-pedestrian accident reconstruction technique, which are to develop more accurate reconstruction softwares, to study uncertainty of accident reconstruction results and to study relationships between traces, were pointed out. And topics, which are uncertainty of simulation resuits, interval-based uncertain optimization methods of vehicle-pedestrian accident reconstruction and relationships between traces, are worth expecting.
