In compact urban environments, public open spaces (POSs) are limited but important places for people’s exercise, recreation, and social activities. The quality of POS is an essential element in measuring the quality of life of urban residents. This study investigates determinants of POS use applying a longitudinal modeling approach using passively solicited data assembled by Baidu heat map. A generalized linear mixed model (GLMM) has been applied to examine the association between POS use and features of the built environment, POS, and socio-demographics while adjusting the confounding effect of various time-varying factors. The results suggest: (1) compact urban environment features are positively associated with POS use; (2) proximity to POS is positively correlated with POS use; (3) substitutional amenities, such as gyms and other POSs, are negatively correlated with POS use; (4) POS visitor density is higher in smaller POSs; (5) females and well-educated people are more likely to visit POSs; and (6) temperature and special events are significantly associated with POS use over time. These results indicate that to better increase POS use, decision-makers may place more POSs in compact urban environments, promote the access to POSs, and improve the quality of small POSs through urban design.
