城市快线建设合理性分析与建设思路探讨

Analysis of the Rationality of Building City Express and Discussion on Construction Ideas

仅有短站间距轨道交通系统不能称其为完善的轨道交通系统,而当前城市轨道交通系统普遍缺失“城市快线”。“城市快线”是对城市轨道交通系统的重要补充,构建完善的城市轨道交通系统,是深入实施“交通强国”战略、打造新时代中国“轨道上的城市”的新举措,必将引领世界城市轨道交通建设步入新阶段。本文根据国内14座拥有三条以上地铁线路城市统计数据,通过对单程通勤距离、线网负荷强度分析,提出建设城市快线的必要性;对中低运量轨道交通不同制式技术参数进行对比,证明中低运量磁浮交通系统最适合与现有地铁系统相互搭配、互为补充,从而构建新时代完善的城市轨道交通系统。

The system of rail transit with only short station spacing cannot be called a perfect rail transit system,and the current urban rail transit system generally lacks the"City Express"The"City Express" is an important complement to the urban rail transit system.Building a perfect urban rail transit system is a new measure to deeply implement the strategy of wtransportation power"and build China's"city on railsM in the new era,and will surely lead the construction of world urban rail transit into a new stage.In the article,according to the statistics of 14 cities with more than three subway lines in China,the necessity of building city express is put forward mainly through the analysis of one-way commute distance and network load strength.By comparing the technical parameters of the diflerent systems of medium-and low-volume rail transit,it is shown that the medium-and low-volume maglev transportation system is best suited to match and complement the existing subway system,so as to build a perfect urban rail transit system in the new era.
