• Authors: Xiaojian Zhang, Xiang Yan, Zhengze Zhou, Yiming Xu and Xilei Zhao
• Abstract summary: This study applies an explainable-machine-learning-based analytical framework to identify the key factors that shape ridesourcing demand. The importance of built environment varies across spatial contexts, and it collectively contributes the largest importance in predicting ridesourcing demand for airport trips. Ridesourcing demand is usually most responsive to the built environment changes for downtown trips, followed by neighborhood trips and airport trips.

• Abstract: The growing significance of ridesourcing services in recent years suggests a need to examine the key determinants of ridesourcing demand. However, little is known regarding the nonlinear effects and spatial heterogeneity of ridesourcing demand determinants. This study applies an explainable-machine-learning-based analytical framework to identify the key factors that shape ridesourcing demand and to explore their nonlinear associations across various spatial contexts (airport, downtown, and neighborhood). We use the ridesourcing-trip data in Chicago for empirical analysis. The results reveal that the importance of built environment varies across spatial contexts, and it collectively contributes the largest importance in predicting ridesourcing demand for airport trips. Additionally, the nonlinear effects of built environment on ridesourcing demand show strong spatial variations. Ridesourcing demand is usually most responsive to the built environment changes for downtown trips, followed by neighborhood trips and airport trips. These findings offer transportation professionals nuanced insights for managing ridesourcing services.

  We show that intrinsic rewards should depend on the agent's information about the environment, remaining to the representation of the information. We show that invariance under congruent Markov morphisms and the agent-environment interaction, uniquely constrains intrinsic rewards to concave functions of the reciprocal occupancy. This framework provides important constraints to the engineering of intrinsic reward while integrating foundational exploration methods into a single, cohesive model.

  Greater distance to the urban centres is associated with increased spatial variability of bus use. Greater separation of trip origins and destinations from the subcentres reduces both spatial and temporal variability. Lower and higher road density is associated with higher spatial variability of bus use especially in morning times.
