标题:车祸中如何估算车辆的速度？
正文:
杭州发生的富家子弟撞人案后，对于发生车祸时的改装车辆的车速，前后不一。在网上查找了一下，找到了这篇关于车祸中计算车辆撞人时的速度估算或计算论文。有心的人可以翻译一下，初步看了，专家最后给出的结论基本符合，不是很离谱。因为影响车祸事后测算车速的因素很多，所以专家给出的速度基本可以接受。下面是几篇关于估算方法的英文文章摘要，附链接。车辆与行人相撞：对行人的影响和预测的验证模型Vehicle–pedestrian collisions: validated models for pedestrian impact and projection Abstract: The most important factor in pedestrian injuries from vehicle collisions is the impact velocity. In cases where the impact configuration can be ascertained, the most common method nowused to determine vehicle speed involves the pedestrian projection distance. The more traditional method of using tyre brake marks is losing applicability as ABS braking systems becomemore common.The two most common impact configurations are wrap projection and forward projection, these being determined by the vehicle/pedestrian geometry and the initial conditions of the impact. In thispaper, two models are presented for pedestrian forward and wrap projection impacts. These models are predicat
