长大纵坡路段事故多发，为研究事故多发路段的事故致因机理，对长大纵坡段的驾驶行为进行基础研究。通过利用激光检测仪，选取长大纵坡段进行交通检测，提取相关检测数据进行分析处理。通过对长大纵坡段车辆速度特性、车辆位置等进行分析发现，长大纵坡段小型车速度上升较快并持续保持高速运行，长大纵坡段大型车速度上升相对缓慢，并在速度上升到一定范围之后，制动保持在自身认为相对安全的速度行驶，长大纵坡段大小型车速度差较大，并且随着速度的增加车辆更加趋于行车道中间行驶，存在较大的追尾事故隐患。

Accidents on long and steep downgrades occurred Frequently.To study the principle of the cause of the accident,a basic research on driving behavior of long and steep downgrades was carried out.Select long and steep downgrades to detect traffic character by using laser detector,and then extract the relevant test data to analysis and processing,the analysis results on long and steep downgrades vehi-cle speed and vehicle location displayed that the small car segment velocity increased rapidly and contin-ued to maintain high-speed operation.Large vehicle segment speed is relatively slow,after the velocity rise to a certain range,the braking measures maintain itself driving with considered relatively safe speed. Velocity difference is large on long and steep downgrades section,and with the increase in speed the vehicle tend to driving more closer to the middle of the lane,which is a big happening probability of rear collision accidents.
