METHOD FOR DETERMINING ROAD TRAFFIC ACCIDENT FACTORS USING VIDEO RECORDING

机译:视频记录确定道路交通事故因素的方法

摘要

FIELD: physics.;SUBSTANCE: to calculate a car speed before the accident, a video recording from the monitor is used, performed at the RTA place, the car movement recorded on video for a time equal to t=1 s is taken into account. The formula is used for determining the speed of the car V=S*Lp.o/Lo.m*t, where V - the car speed in real time, S - the car way fixed on the monitor at the car movement for 1 s, Lp.o - the actual overall car length fixed on the monitor, or the actual distance between the light posts fixed on the monitor, Lo.m - the overall length of the same car measured on the monitor, or the distance between the same light posts on the monitor, respectively, t - the time interval of the car way fixed on the monitor equal to 1 s.;EFFECT: increasing the accuracy of determining the RTA factors.;2 dwg
