山区高速公路长大纵坡路段安全设计要点探究

Key Points of Safety Design of Large Longitudinal Slope Section of Mountain Expressway

分析目前山区高速公路大长纵坡路段交通事故频发的原因,结合西昌至宁南高速公路工程可行性研究项目,主要从公路路线设计方面提出降低长大纵坡路段事故率的安全措施。希望通过相关措施的提出,力求降低山区高速公路大长纵坡路段交通事故的发生率。

This paper analyzes the causes of frequent traffic accidents in the large and long longitudinal slopes of mountainous expressway at present. Combined with the feasibility study project of Xichang Ningnan expressway project, it mainly puts forward safety measures to reduce the accident rate in the long and long longitudinal slopes from the road route design. We hope to reduce the incidence of traffic accidents in large and long longitudinal slope sections of mountain expressway through relevant measures.
