Practice of Urban Rail Transit Network Planning in Transboundary National New Areas: A Case Study of Guian New Area

This study analyzed two important issues that should be paid attention to in the planning of urban rail transit network across city administrative boundaries based on the case of rail transit network planning in Guian new area.The two issues are how to determine the planning scope and how to develop a mode of rail transit rationally.The network planning was out of the restrictions on administrative divisions.The viewpoint of large Guiyang metropolitan area rail transit network guiding Guian new area development was proposed from the perspective of regional integration.To effectively strengthen the quick connection between the Guian new area and Guiyang,and to guide the development of the internal district of Guian new area,as well as to realize the goal of integration of Guian,the constructions of the two networks in Guian new area,including city express line through the core area and general urban line network,were proposed.
