Abstract:

To identify the spatial difference of the synergy degree of urban development level and rail transit passenger flow and the impact of urban development elements on rail transit passenger flow in different space areas, this paper introduced Moran's I describing the characteristics of spatial agglomeration and proposed an evaluation methodology of urban development level around rail transit stations. The study used the spatial agglomeration character of both urban development level and rail transit passenger flow as the synergy degree judgment standard and divided the study objective into several station groups. The Geographically Weighted Regression (GWR) model was utilized to evaluate spatial correlation of urban development level and rail transit passenger flow, as well as the impact of urban development elements on rail transit passenger flow. The case study shows that urban development level has significant impact on rail transit passenger flow in the area with high degree of coordination of these two parameters. The impact degree of urban development elements on rail transit passenger flow is as follows: the density has larger impact on rail transit passenger flow, followed by the convenience of transport interchange, the diversity of urban functions, and the compactness of development.
