Urban agglomeration has become the new normal of urbanization in China. As an important condition to promote regional growth, the reliable operation of urban agglomeration transportation has a significant impact on the formation and development of urban agglomeration. This study used multi-scale research methods to explore the spatial heterogeneity of urban agglomeration transportation. Firstly, the transportation (including infrastructure, transportation volume) of Guanzhong Plain urban agglomeration was selected as the research object. And with the help of weighted average travel time and reachability coefficient, we analyzed the traffic topological characteristics of the composite network composed of highway and railway. Meanwhile, we used ArcGIS software to analyze the spatial distribution and centrality characteristics of transportation stations. Thenafter, based on the urban space economic linkage model and the ArcGIS radial flow module, the temporal and spatial evolution characteristics of the traffic flow in the Guanzhong Plain urban agglomeration were discussed. Finally, according to the analysis results, we studied the heterogeneity characteristics of grade, structure and function of Guanzhong Plain urban agglomeration and put forward some suggestions for future development.
