汽车交通事故碰撞速度多值问题的研究

Multi-Value Problem of Collision Velocity in Motor Vehicle Accident

交通事故碰撞速度的判断是事故再现的重要内容之一。由于交通事故的复杂性和各干扰因素出现的偶然性，通常在事故现场可能找到若干个能用于再现事故的证据，需要专家去判断取舍。本研究提出一个综合评判计算方法，来推算碰撞速度，可以避免按单一方法计算，因参数选择或计算错误所起的影响，并可间接校验某些事故现场遗留痕迹的真伪，剔除个别含有假象的证据。

The judgement of motor vehicle collision velocity is an important problem in traffic accident reconstruction.Because of the complexity and the contingency of the interference factors,there are several proofs at accdent spots which can be used to reconstruct the accident 3on the other hand, every expert may take his method or different proofs to calculate the collision velocity.This paper presents the comprehensive decision-making method for calculating the collision velocity.This method uses all proof on' the spots by means of different formulae, so that it can avoid the effects of only one calculating method or choice of parameters or calculating errors on the judgement of collisiong velocity.And the proofs with falseness can be rejected by the comprehensive decision-making method.
