题目： Exploring the built environment impacts on Online Car-hailing waiting time: An empirical study in Beijing 期刊： Computers, Environment and Urban Systems volume DOI ： https://doi.org/10.1016/j.compenvurbsys.2024.102205 01 摘要 Waiting time is a critical metric for evaluating the quality of online car-hailing services, with studies indicating a close association between Online Car-hailing waiting time (CWT) and the urban built environment (BE). Points of interest (POI) data is widely utilized to characterize the built environment. However, quantifying the proper combination or spatial relationships between different types of POIs to capture the functional features of the built environment within a region poses a challenge. This paper proposes a framework for analyzing built environment characteristics based on a semantic probabilistic topic model utilizing Latent Dirichlet Allocation, demonstrating that integrating the building area of POIs along with the travel activit
