摘要
随着高速公路建设的快速发展,人们对互通立交的行车安全提出了新的要求,作为影响互通立交行车安全的行车视距得到了较为广泛的研究。文章首先阐述了关于立体交叉线路视距的相关规定,对于影响行车视距的因素进行了分析,确定了高速公路互通立交的行车视距指标,最后提出了高速公路互通立交视距优化对策,旨在为类似项目提供一定的理论参考。
With the rapid development of expressway construction,people put forward new requirements for driving safety of interchanges.The driving sight distance that affects the driving safety of interchanges has been widely studied.This paper first expounds relevant regulations on the sight distance of interchange lines,analyzes the factors that affect the driving sight distance,determines the driving sight distance index of expressway interchange,and finally puts forward optimization countermeasures of the sight distance of expressway interchange,aiming at providing some theoretical reference for similar projects.
