支路不同红线宽度对比分析

Comparative analysis of different red line widths of branch roads

目前国家及交通行业相关规范针对支路红线宽度的要求是14~20 m,取值范围较为宽泛,设计人员在实际规划设计工作中,在确定支路红线宽度时往往不知所措,红线宽度的设置存在较大的随意性。从道路断面功能的角度分析了不同红线宽度的支路功能差异,作为红线宽度选取的重要依据;规划设计人员可根据支路所属片区的交通出行特征,选取适宜的道路红线宽度。本研究对于实际工作中确定支路红线宽度具有较为重要的指导意义。

At present,the relevant national and transportation industrial specifications for the width of the branch road red line are 14~20 m,with a wide range of values.Designers are often at a loss when determining the width of the branch road red line in the actual planning and design work,and the setting of the width of the red line is quite arbitrary.From the perspective of the functions of different road sections,this paper analyzes the functional differences of branch roads with different red line widths.As an important basis for selecting the width of the red line,the planning and design personnel can select the appropriate width of the red line according to the traffic characteristics of the area to which the branch road belongs.This study has a more important guiding significance for determining the width of branch road red line in practical work.
