Analysis on the Horizontal and Vertical Alignment Indexes of Expressway and Their Influence on Driving Safety
In order to ensure the quality of expressway route design,this paper summarizes the classification methods and selection principles of horizontal and vertical alignment indexes,and discusses the selection methods of horizontal alignment and vertical alignment indexes in combination with the current specifications.At the same time,an expressway is taken as the research object and divided into several evaluation units,and the driving safety of the curved slope section is analyzed.The research results can provide theoretical guidance for similar projects.
