摘要
高速公路互通立交是连接高速公路与高速公路、高速公路与低等级道路的重要枢纽,互通立交的路线视距是立交构建的关键影响因素之一,构建合理的路线视距长度可在节省公路初始投资的前提下,让驾驶员在行驶过程中有足够的视距作出变速或变道等预判操作,从而有效减少交通事故的发生。文章分析并计算了匝道、分流区域和合流区域的安全视距长度,旨在为高速公路互通立交的构建和通行安全提供参考。
Expressway interchange is an important hub connecting expressway and expressway,expressway and low-grade road.The route sight distance of interchange is one of the key factors affecting its construction.Constructing a reasonable route sight distance length can allow drivers to have sufficient sight distance to make prediction and operation such as speed change or lane change during driving on the premise of saving initial investment,thus effectively reducing the occurrence of traffic accidents.This paper analyzes and calculates the safe sight distance length of ramp,diversion area and confluence area,aiming to provide reference for the construction and traffic safety of expressway interchange.
