干线道路共线设计研究

摘要:

干线道路共线是指两条或两条以上道路在一定长度范围内共同敷设路线,涉及到多系统、多层级的廊道及节点问题。规划、建设实践中,共线模式逐渐从“被动为之”演变为“主动而为”,是城市交通可持续发展解决方式之一。本文分析国内外干线道路共线案例,并依据空间形态和连接条件差异,对共线形式进行分类和梳理。对于道路共线设计,从功能定位、系统结构、横断面布置、车道数设计、端部连接方式、交通管理措施等方面进行简要分析,并提出共线系统结构分析和共线影响范围特征路段定义。

Abstract:

Sharing corridor designing for arterial roads is defined as integrating two or more arterial roads into a definite corridor in a limited section, which involves multi-systematic and multi-level problems connected with both junctions and corridor. In recent practices of planning and building, sharing corridor designing is shifting from a passive mode to a positive mode and becoming one of solutions for durable urban transportation developing mode. Delivering and analyzing projects involved sharing corridor layout of roads throughout the world, the writer gives definitions for different sharing corridor layout. Furthermore, a brief analysis of sharing corridor designing is focused on function definition, framework, cross section, lane calculation, junction planning and traffic management. Lastly a special architecture and characteristic sections for sharing corridor designing were developed.
