Abstract:
Aiming at the current structural contradictions between supply and demand in the planning, construction, and operation of urban rail transit (URT), the degree of imbalance between the demand for URT passenger flow and the network supply in major cities were evaluated in China in 2025. Firstly, a tiered method of URT supply potential and a transport demand analysis model was proposed based on tiered supply potential on the basis of the entropy theory and traffic demand analysis method, to predict the quantified and hierarchical supply potential of URT and the passenger demand intensity. Secondly, based on the per capita density and passenger flow intensity indicators, URT was classified. Finally, the 14 typical large cities in China were selected as research samples to verify the rationality of the method and the feasibility of the model. The results show that 60% of highpotential cities are prone to supply surplus, which is related to the low share rate of URT passenger flow caused by the urban polycentric space and the high passenger flow intensity. Among them, Guangzhous excessive passenger flow intensity and the small network scale of the Xian have led to the illusion of surplus supply. 60% of the mediumpotential cities and 75% of the lowpotential cities are undersupplied, which is related to the serious jobhousing imbalance and the low network density and passenger flow intensity. As of 2025, the samples will be divided into five types, based on the changes of population density and passenger flow. Among them, Beijing is a highdensity and highintensity city, with good network operational benefits. Guangzhou, Chongqing, and Nanjing are highdensity and mediumintensity cities. Tianjin, Shenzhen, Shenyang, Changchun, and Dalian are mediumdensity and highintensity cities. Xian and Shanghai are mediumdensity and highintensity cities. The supply and demand of these four types of cities are more coordinated and balanced. Highdensity and lowintensity cities, such as Hangzhou, Chengdu and Wuhan, should reevaluate the scientific nature of the road network layout and rapidly the demand for passenger flow. 5 tabs, 2 figs, 25 refs.
