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.
