Abstract

The demand for urban public transport is closely associated with the built environment, as analysed at both the city and neighbourhood levels. Although neighbourhood-level built environments have been studied thoroughly, city-level factors have received less attention. In this study, a machine learning framework is developed to explore the influence of multilevel factors on public transport commuting. A case study of 79 cities in mainland China reveals: (1) The highest accuracy was achieved by incorporating individual socioeconomic and commuting characteristics, and neighbourhood- and city-level built environments. (2) The cumulative importance of built environment factors exceeds 50%, with approximately half contributed by city-level variables. (3) All level factors exhibit nonlinear effects, with some variables displaying threshold effects. (4) Cities are classified into five distinct groups based on city-level variable effects. These findings highlight the necessity of incorporating multi-level factors into planning practices and targeted policy recommendations for different types of cities.
