基于运行速度的山区高速公路长大纵坡路段安全设计研究

Study on Safety Design of Large Longitudinal Slope Section of Mountain Expressway based on Operation Speed

随着国民经济水平的不断提高,山区高速公路的建设数量有所上升。但因受到地势、地形等相关因素的影响,车辆在山区高速公路行驶的过程中易出现交通安全事故。本文主要对长大纵坡路段的安全设计方法进行研究,探究提高山区高速公路安全性能的有效措施。

With the continuous improvement of the national economic level,the number of highway construction inmountain areas has increased.However,due to the terrain,terrain and other related factors,leading to vehicles in themountain expressway in the process of traffic safety accidents prone to occur.In this paper,the safety design methodof the long longitudinal slope section was studied,and the effective measures to improve the safety performance of thehighway in mountainous area were explored.
