摘要
由于汽车-行人碰撞事故现场勘测精度低、占道时间长,信息采集误差大,造成过程再现与真实事故过程不符,通过采用数字化重构和计算机仿真技术进行交通事故现场重构和过程再现,对重大车人碰撞事故重要参数和发生过程进行再现,为交警部门事故鉴定和责任认证提供科学依据。通过交通事故实际案例现场重构和仿真结果表明:重构现场图与事故现场吻合度大于95%,事故再现结果偏差不超过10%,再现结果能够与交通事故现场勘测相吻合,为事故现场重构与过程再现提供了新途径。
The car-pedestrian impact accident scene investigation has a low precision,long time of occupying road,and big information acquisition error.As a result,the process reappearance does not match the real accident process.The use of the digital reconstruction and computer simulation technology carries out the traffic accident scene reconstruction and the process reappearance,which rebuilds the important parameters and the process of the significant traffic accident.It can provide a scientific basis to identify accident and authenticate responsibility for the traffic police department.The scene reconstruction and simulation result of the actual traffic accident case show that：Actual cases through the accident scene reconstruction and simulation results that：it is more than 95 percent that the reconstruction result of the scene coincides with the accident scene,the deviation of the accident reconstruction result does not exceed 10 percent,and the reappearance result is a nice match for the accident scene investigation data.That provides a new way for the accident scene reconstruction and process reappearance.
