研究目的:城市轨道交通环线指的是线路构成的-个环形,列车在其上环形运行的交通线。由于轨道交 通系统的特殊性,其环线与道路环线的差别较大。本文通过对环线功能的分析,结合苏州总体规划及居民出 行分布、现状轨道交通线网,对苏州轨道交通规划是否设置环线进行分析与探讨,供苏州轨道交通规划参考。
研究结论:(1)就适应苏州总体规划角度来看,苏州市域将形成“-心两轴-带”的城镇空间结构,中心城 区规划形成“-心两区两片”构成的“T型”城市空间结构,设置内、外环线均不适宜,其要实现的功能与苏州 实际情况不相符;(2)在棋格网为主的前提下适度增加L型,S2型线路,可提高线网的可达性;(3)城市轨道交 通线网是否采用环线应结合城市总体规划进行深人论证,以确保规划的合理性;(4)本研究结论可以作为城 市轨道交通线网规划环线设置与否的参考。
Research purposes:Urban Rail Transit link refers to a line consisting of a ring,trains run on the ring. Because of the special nature of rail transport system,it is different from the road link. In this paper, through the analysis of the link function,combined with the general plan and trip distribute in Suzhou,the link of the Suzhou rail transportation planning is analyed and discussed. It can provide the references for planning of Suzhou rail transit.
Research conclusions:(1)Acorrding to the Suzhou General plan,Suzhou City will form the urban spatial structure which is“one center, two axes,one region",the central city will plan to form a urban spatial structure composed of “one center, two districts,two regions" which is”T-type n,internal and external link are not suitable for Suzhou,the functions to be achieved and Suzhou’s actual situation does not match. (2) Based on the checkerboard type road,L or S2 line are proposed to increase in the mainly trip direction,in order to improve the accessibility of the line network. (3)The setting link of city rail transit network should be in-depth discussion combined the general plan,to ensure that the planning of rationality. ( 4)The research conclusions can be used as urban rail transit network planning for link set or not.
