十字路口是交通事故发生较多的地方,在红绿信号转换之际,汽车突然起步加速而发生机动车碰机动车、机动车碰自行车、机动车碰行人等交通事故,往往需要分析机动车行使时间、距离、速度等问题。还有机动车在十字路口的斑马线前进行急刹车发生碰撞事故,也需要对机动车的制动性能及刹车速度等进行鉴定。本文利用“便携式制动性能测试仪”来研究机动车起步加速特性,实验结果可以用于有关交通事故分析鉴定。
Crossroads are where traffic accidents occur more. On the occasion of the conversion of red and green signals, a sudden acceleration of the car suddenly takes place to cause traffic accidents such as motor vehicles hitting motor vehicles, motor vehicle hitting bicycles, motor vehicle hitting pedestrians, and the like, Time, distance, speed and other issues. There are motor vehicles at the crossroads of the zebra crossing emergency brake collision occurred, but also the need for vehicle braking performance and braking speed identification. This paper uses “portable brake performance tester ” to study the starting acceleration characteristics of motor vehicles, the experimental results can be used for the identification of traffic accidents.
