Abstract:

Both land use allocation and transportation system play important roles in urban system. As they influence each other, analysis of their correlation is of great significance for spatial planning and development decision-making of Chinese urban areas. In this research, centrality is selected because of its advantage in describing the accessibility of urban road network. From the perspective of street centrality, using multiple centrality assessment model and kernel density estimation method, this study analyzed the spatial distribution and transit-oriented characteristics concerning different types of urban functional land use in the central area of Beijing city. From the statistical and spatial characteristics of each street centrality and the map of urban land use kernel density, it is found that the global closeness centrality shows the monocentric pattern clearly, while the global betweenness centrality and straightness centrality are both polycentric, with a relatively strong polycentricity for the global straightness centrality. The global street centrality is significantly correlated with functional areas of residential, commercial and service facilities, and administration and public services, while its relationships with other functional land use areas are relatively weak. In the meantime, street centrality has little correlation with the urban mixed land use, which indicates that the accessibility, convenience and other advantages of road network have no significant influence on the urban mixed land use in Beijing central city. Under the influence of bid rent of land price and residents' housing choices, the global street centrality is more related with the residential area than the areas of commercial and service facilities and administration and public services. In such a context, this means that it is more transit-oriented for residential area, which is different from the situation in the American and European cities. Furthermore, under the influence of residents' travel habits, the areas of residential, commercial and service facilities have the closest relationship with global betweenness centrality, but administration and public services areas have the closest relationship with global straightness. The aforementioned results imply that street centrality can capture the spatial distribution of urban functional land use and provide a valuable guidance for transportation and land use planning.
