行车视距是指停车视距、超车视距、会车视距和错车视距的总称。汽车行驶时,驾驶人员从看到前方路面上的障碍物或迎面来车起,至采取措施(停车、超车、会车、错车)避免与障碍物或迎面来车相撞止所行驶的距离。与汽车行驶速度、障碍物种类、路面状况有关。'各国的技术标准规定了不同车速下的最短停车视距和超车视距,近似地取会车视距和错车视距为停车视距的两倍。在这个距离内,凡高于1.2m的阻碍司机视线的物体都要清除。
The driver's sight distance is the importance factor of guaranteeing the traffic safety. The different kinds of roads line shape(including straight line ,horizontal curve, vertical curve) correspond to different sight distance.
驾驶员行车视距是保证行车安全的重要因素,各种道路线形(包括平直线形、平曲线形、纵曲线形)分别对应不同的行车视距。
