对轨道交通环线布设位置和换乘效果的探讨

Exploration on the Location and Transfer Effect of Loop Line for Rail Transit

研究目的:城市轨道交通环线是轨道交通线网中的一种线形,本文通过梳理国内外环线布设案例,对轨道交通环线的效用进行分析,重点对棋盘型路网城市中轨道交通环线换乘功能进行理论方面的探索,以期全面认识城市轨道交通环线的功能,供城市轨道交通线网规划参考。研究结论:城市轨道交通环线设置与城市总体规划、城市空间形态、城市轨道交通线网的形态密切相关,其互动关系可概况为:(1)环线布置在城市中心,有做大城市CBD的作用;(2)环线布置在城市外围,具有对趋心外围客流的分流作用;(3)在棋盘型路网城市中,环线的换乘功能不优于棋盘型线网;(4)该研究成果有利于增强轨道交通环线应用的合理性。

Research purposes： The loop line is a kind of the urban rail transit network. In this paper, through summarizing the urban rail loop link layout cases in domestic and foreign, the author analyzes the utility of loop link, focuses on the exploration of the theory on the transfer effect of the loop link in the city of chessboard type road network. It can help us to understand the rail transit loop link with a comprehensive view. Research conclusions：The location of the urban rail transit loop link is closely related with the overall urban planning, city spatial form, city rail transit network forms. The interactive relationship of both contains three sides ： （ 1 ） When the loop link is located in center of the city, it can help the CBD more powerful and prosperous. （2） When the loop link is located in outside of the city, it can help diverting the passengers who need come to the center. （3） In the city of chessboard type road network, the transfer effect of loop link is not better than the grid rail transit network. （4）The results of the research are conductive to enhance the rationality of rail traffic loop applications and can provide some references for the urban rail transit network planning.
