Abstract:

This paper developed a method to assess the appropriateness of urban structure via evaluating the accessibility of public transportation. Through a validated accessibility index, it combined the physical setting of urban environments with the residents' satisfactions toward public transportation. Taking Beijing as an example, this paper first analyzed the influencing factors of the accessibility of public transportation from three perspectives including public service, local development status, transportation and road construction. Then, it built a hierarchical logistic regression model of satisfaction. It was found that the satisfaction of people varied spatially, with the marginal effect of within the 5th Ring Road being lower than that outside the 5th Ring Road. The connectivity to the main places of the city by public transportation, and the density of bus stops within a distance of 800 m were found to have significantly affected the satisfaction of people toward public transportation. In addition, people of different attributes valued differently. The results had implications for improving the transportation environment of Beijing. (1) At present, the investment of public transportation should focus on the areas in the built-up areas inside the 5th Ring Road rather than the suburban areas. (2) It is socially desirable that the 800-m-service areas of bus stops cover the whole city; and according to the function of various areas, the optimal density of bus stops should be different. (3) The connectivity to the main function nodes of the city by public transportation should top the agenda on the planning of bus lines, as it can substantially improve the efficiency of public transportation system and the satisfaction of the people. (4) The spatial distribution of the people with different attributes such as age and income should be taken into account when local public transportation policies are made.

Key words: urban structure, satisfaction, public transportation, accessibility, connectivity
