Demonstration of Separate Section Standards for Expressway High-intensity Interchange Group Intersections

文章结合南京至马鞍山高速公路江苏段扩建工程,对高密集互通群立交路段分离式断面标准进行论证,从分析老路现状的拓宽改造条件入手,综合考虑高密互通群路段的断面方案,高密集互通群立交改造方案,高密集互通群立交交通适应性等方面因素,得出了功能清晰、服务水平高、交通运行均衡性良好、工程经济合理的扩建方案。

This paper combines the expansion project of the Jiangsu section of the Nanjing-Maanshan Expressway to demonstrate the separation section standard of the high-intensity intercommunication group crossing section.Starting from the analysis of the widening and transformation conditions of the old road,the comprehensive consideration of the section scheme of the high-density intercommunication section is highly dense.Inter-community group interchange transformation plan,highintensity inter-communication group interchange traffic adaptability and other factors,resulting in clear function,high service level,good traffic operation balance,and reasonable economic and economic expansion plan.
