道路交通事故再现模拟分析系统的研究

本文研究开发了道路交通事故再现模拟分析系统。基于现实世界中事故形态千差万别的特点，采用人工智能技术、使用不同于其它系统的参数子集建立模型，根据特定事故形态特点进行模型假设。采用虚拟现实技术，以Opengl接口开发了三维动画演示模块，在虚拟世界中演示车辆运动，允许用户改变场景元素。系统中还开发了车辆技术参数数据库。并用此系统对实际的事故进行了模拟分析，与PC－CRASH系统的结果进行了对比，结果基本一致。

A Study on Simulation and Analysis System of Accident Reconstruction

A simulation and analysis system of accident reconstruction is developed in this paper. Considering the great difference between accident types, the technique of artificial intelligence is used to develop the models, which rely on different parameter subsets from those adopted in other systems. And the model assumption is based on the characteristics of the given accident type. The demonstration module of three-dimensional animation is developed using the technique of virtual reality and OpenGL interface. The vehicle motion is demonstrated in the virtual world, and the scene elements can be easily changed to fit the real scene. A vehicle parameter database is also developed, and a real accident case is analyzed and simulated with both this system and PC-CRASH. The result of this system basically agrees with that of PC CRASH system.
