既有高速公路增设枢纽设计研究

Research on the Design of Adding Hubs to the Existing Expressways

以太原西北二环高速公路清徐南枢纽为例,介绍了在新增枢纽与既有互通净距不足的情况下,综合考虑互通功能、交通流优化、工程规模、旧路改造强度等因素,比选得出合理的枢纽方案。

Taking Qingxu south hub of Taiyuan northwest second ring expressway as the example,the comprehensive consideration of interflow function,traffic flow optimization,project scale,old road reconstruction intensity and other factors is introduced under the condition of insufficient clear distance between the new hub and the existing interchange and the reasonable hub scheme is obtained through the comparison and selection.
