Quantitative Study on Relationship between Regional Spatial Structure and Regional Intercity Rail Transit Network

The regional spatial structure and traffic system have the time and space interactive relationship. In this paper, a new graph is described for the relationship between regional spatial structure and regional intercity rail transit network. Taking Wuhan urban agglomeration as an example, the quantitative relationship between the spatial structure and the intercity rail transit network is analyzed. Study results: (1) The main economic relation intensity network and the intercity rail transit network have a correlation. (2) The economic relation intensity between cities is strongly related to the passenger volume. (3) The economic relation intensity and the intercity rail transit construction schedule also have a high correlation. Therefore economic relation intensity is the foundation of regional intercity rail traffic network layout.
