摘要
改扩建成为解决我国早期修建的高速公路通行能力不足、服务水平下降的关键手段之一。论文以高速公路改扩建工程施工区为研究对象,根据高速公路改扩建施工区长度计算模型,论证施工区中警告区、过渡区、缓冲区、工作区、终止区长度划分,从而保障交通运行效率、交通运行安全、施工进度等,为同类高速公路改扩建工程施工区长度划分提供借鉴。
Reconstruction and expansion has become one of the key means to solve the problem of insufficient traffic capacity and declining service level of expressways built in the early stage of our country.This paper takes the construction area of expressway reconstruction and expansion project as the research object.According to the calculation model of the length of the construction area of expressway reconstruction and expansion,it demonstrates the length division of warning area,transition area,buffer area,work area and termination area in the construction area.So as to ensure the traffic operation efficiency,traffic operation safety,construction progress,etc.,and provide reference for the length division of construction area of similar expressway reconstruction and expansion projects.
