Network Evolution-based Planning Model for Intercity Railway Network within Urban Agglomeration

HUANG Chao;LIU Su;LV Ying;School of Transportation and Logistics,Southwest Jiaotong University;China Railway First Survey & Design Institute Group Co.Ltd.;  
Intercity railway network plays an important role in the integration of urban agglomeration, and reasonable planning is of great significance on the basis of urban agglomeration spatial structure. This paper,based on network evolution, takes node importance and economic contact intensity as major parameters of network evolution, and a planning model of the intercity railway network of urban agglomeration is constructed, under the comprehensive consideration of social economy of the specific urban agglomeration.With the analysis of technical performance and constraints of the intercity railway network, evolution mechanism and evolution algorithm are present. At last, the Chengdu-Chongqing urban agglomeration is taken as a case to validate the planning model. The result shows that this model is reasonable and efficient,and provides an important guidance on the intercity railway network planning.
