Abstract
The influence of the built environment on the integration of dockless bike-sharing (DBS) with metro stations has been a persistent concern for urban transportation planners. However, empirical evidence regarding the spatial and temporal heterogeneity of the nonlinear relationships between the built environment and DBS-metro integrated use remains limited. Taking Beijing as a case study, this study employs an extreme gradient boosting (XGBoost) model to elucidate the intricate associations between the built environment and hourly DBS-metro integrated use, considering distinct functional areas (i.e. residential, mixed-use, and public management and service area) during five temporal periods (i.e. weekday peak, weekday non-peak, weekday nighttime, weekend daytime, and weekend nighttime). The results confirm significant spatiotemporal variations in the nonlinear relationships within specific functional areas and time periods, revealing key influential variables. Sky view availability consistently emerges as a pivotal factor across all areas and time periods. In residential functional areas, bus stop density and pedestrian space significantly drive nighttime integrated use, while in mixed functional areas, road congestion index, metro ridership density, and distance to the city centre dominate during weekday morning peaks. Public management and service areas show pronounced effects of metro ridership and population density during weekend daytime and nighttime. The findings provide insights that can inform equitable urban planning strategies and foster a more accessible transportation system.
