Abstract

Cycling behavior is affected by various factors, including infrastructural and environmental factors. While bike infrastructure and air quality may have effects on cycling, their joint impacts were less known. The present study examined yearly changes in public bike-sharing (PBS) usage across 423 neighborhoods in Seoul, South Korea between 2018 and 2021. We quantified how concurrent changes in the number of PBS rental stations and ambient PM_2.5 concentration levels influenced PBS usage patterns using a statistical method, namely, a variant of difference-in-difference method. The results showed that the relative rates of changes in the PBS usage (i.e., rental frequencies) for 1 μg/m³ increase of PM_2.5 and one bike station expansion are −0.168 (95 % CI; −0.188, −0.149) and 0.024 (95 % CI; 0.019, 0.029), respectively. We also found that adult cyclists aged over 50 years old are more sensitive to poor air quality than younger age groups. Our analysis suggests that improvements of PBS infrastructure and cleaner air quality are both positively associated with increased PBS usage.

期刊介绍： Cities offers a comprehensive range of articles on all aspects of urban policy. It provides an international and interdisciplinary platform for the exchange of ideas and information between urban planners and policy makers from national and local government, non-government organizations, academia and consultancy. The primary aims of the journal are to analyse and assess past and present urban development and management as a reflection of effective, ineffective and non-existent planning policies; and the promotion of the implementation of appropriate urban policies in both the developed and the developing world.
