Bicycle-transit integration is important for improving the efficiency and sustainability of public transportation systems in urban areas. Urban greenness around metro stations is an important factor affecting the use of cycling to or from metro stations. However, the evidence for the association between urban greenness and cycling behaviors is inconclusive. In addition, few studies have been conducted in developing countries, such as China, which has a long tradition of cycling, although the proportion of cycling as a transportation mode is declining. This study aimed to explore the relationship between eye-level greenness and cycling use around metro stations in Shenzhen, China, based on free-floating bicycle data and street-view image data. It focused on the effect of eye-level greenness on cycling frequency near metro stations. The results indicate that eye-level greenness was positively associated with cycling frequency on weekdays and on weekends within three buffer sizes around metro stations (500 m, 1000 m, and 1500 m). The effect of eye-level greenness on cycling frequency was greater on weekends than on weekdays. Our findings suggest that providing sufficient and visible greenery along streets and cycling lanes around metro stations may promote cycling use and bicycle-transit integration.
