驾驶员正常的反应过程是:发现物体、做出判断、采取行动,一般约为2.5秒。车速为72公里/小时,如果司机的视力为1.2,则实际视力将下降至0.7,车速为100公里/小时,人的视野仅为45度。因此,如果在高速路上喜欢开快车,车速为120公里/小时,人的反应距离为83米,加上车辆制动和惯性滑行等因素,有效反应距离实际要超过百米。若达不到这个距离,遇到 The driver’s normal reaction process is: discover objects, make judgments, take action, usually about 2.5 seconds. The speed of 72 km / h, if the driver’s vision is 1.2, the actual vision will drop to 0.7, the speed of 100 km / h, the human eye is only 45 degrees. Therefore, if you like to drive fast on the highway, the speed is 120 km / h, the reaction distance of 83 meters, plus vehicle braking and coasting and other factors, the effective response distance actually more than 100 meters. If you can not reach this distance, encountered
