Abstract
Urban public transit is an important solution for narrowing the mobility gap between captive riders and choice riders and to address issues of social equity. An equitable transit system essentially could meet the needs of transit dependents and maximize the scope of public transit services. To acquire a better understanding of transit equity, we use Lorenz curves and the GINI coefficient to measure the relative supply of public transit to the population and employ the spatial overlay method to analyze the matching degree of transit supply and demand in Guangzhou, China. The findings show that there are obvious and unequal differences between the levels of transit service in the internal zones. The spatial coverage rate and number of stop services of the outer city are significantly less than that of the inner and middle city. Eighty percent of the population shares only 36.7% of the public transit supply in Guangzhou. Most communities of low-supply and high-need public transit are distributed contiguously in the eastern Baiyun and southern Huadu districts. This distribution pattern is beneficial to the transit agency, which could improve the supply in these areas to avoid the risk caused when a large number of residents lack access to public transit services. The results could serve as an excellent foundation for planning the handling of spatial gaps in the Guangzhou public transit supply.
Highlights
Vitality, a significant indicator for measuring a city, lies in spatial accessibility
If Guangzhou in its entirety is evaluated, only 34.76% of Guangzhou is within a walk catchment for public transit
This paper adopts the method of public transit supply construction, associates measures of social needs used in existing studies, and applies the method on a community scale to discuss the spatial differentiation of transit access of communities related to residents’ needs
Summary
A significant indicator for measuring a city, lies in spatial accessibility. The growth of the population and the expansion of urban space in a mega-city determines two main issues that must be solved during the pursuit of sustainable development: intensive land use and the transformation of urban spatial structures from the single-center pattern to the multi-center one. Urban transport networks play a guiding role in forming urban spatial structures and land use patterns [2]. The transportation problems of the big cities in China are serious, which are mainly manifested in traffic congestion, air pollution, and low travel efficiency [3]. Faced with a huge transport demand and overall transportation problems, China’s large cities must implement public transit strategies, make them a priority, and establish a public-transit-oriented land use pattern to achieve the goal of urban sustainable development [4,5]
