Comparison of Urban Rail Transit Service Population Among Beijing,Shanghai,Guangzhou,Shenzhen,Chengdu,and Tokyo
In order to investigate the relationship between rail transit services, population distribution, and urban functional layout, this paper takes Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu, and Tokyo, Japan as the research objects. The spatial characteristics of the population covered by urban rail transit in six cities are compared based on distance and time as the basis of circle division, and their coupling rela-tionship with urban functional layout is discussed. Furthermore, the relationship between rail transit opera-tion and the population covered in six cities is quantitatively analyzed in terms of transportation capacity. The results indicate that the population coverage of rail transit is decreasing radially, and the proportion of population covered by rail transit to the total population in the region is below 10％in five Chinese cities outside the 15 km circle, while it is above 20％in Tokyo. The main functional areas of the five Chinese cit-ies are concentrated in the city center, while the main functional areas of Tokyo are relatively scattered but still have a higher coverage rate of rail transit, which has a more significant role in supporting the spatial structure of the city. The transportation capacity of six urban rail systems show a positive correlation with the population covered by rail transit from an overall perspective. The correlation of Tokyo rail transit is re-flected in the matching of supply and demand through more flexible routing organization and capacity allo-cation.
