| 摘 要： | 从两车刮擦交通事故的实际现象出发，分析了各种相对速度情况下，一辆车的车身凸起刮擦另一辆车的轮胎胎侧表面所遗留的刮擦痕迹。提出了基于胎侧表面擦痕估计交通事故车速的新方法，推导出根据这类痕迹估计两车相对速度的公式，给出了在交通事故处理中应用的实例。

| Abstract: | Based on the actual sideswipe collision traffic accident with variou s relative speeds of two vehicles, the scraped marks on tire sidewall of a vehic le made by the protrusion of another vehicle body are analyzed. A new method to estimate the relative speed of two vehicles based on scratched marks is put forw ard with calculation formulae deduced. The method is illustrated by a real traff ic accident example. |
