Abstract: Investigating the relationship between transportation system and urban spatial expansion is an important starting point for revealing interactions between transportation and economic growth. Existing studies in development economics and transportation economics frequently used indicators such as transportation investment and operating mileage of railways and highways to reflect the level of development of traffic infrastructure. These indicators can well demonstrate the investment and construction scale in relation to transportation system as well as well fit the inherent requirement of economic models, yet they are insufficient in reflecting the operation level and efficiency of transportation facilities and their spatio-temporal differentiation. Taking the Wuhan Urban Agglomeration (WUA) as an example, this paper extracted urban land area information and road network in 2000 and 2010 using Landsat imageries through the application of remote sensing and GIS technology. It investigates the spatio-temporal pattern, relationship and driving mechanism of accessibility as well as transport dominance and urban spatial expansion with the application of isochrone overlay and index classification methods. The results indicate that an interdependent and bi-directional relationship exists between transportation system and urban spatial expansion. The transportation system plays an important role in supporting and promoting economic growth and agglomeration of population and industry, which are intrinsically related to spatial expansion of urban land, through direct impacts, external effects as well as multiplier effects. Correspondingly, urban spatial expansion stimulates and ensures the improvements in the quantity and quality of transportation system. Unbalanced distribution of the transportation system is contended to be an important factor causing increased regional economic disparity. The policy implications are that, the government should attach more attention to formulating differentiated transportation development strategies and improving the integrated transportation system in the metropolitan area, which may facilitate accelerated economic growth and reducing regional economic disparities.
