The novel coronavirus disease (COVID-19) outbreak has put the entire world in a pandemic situation. In response, strict screening, quarantine protocols, and contact tracing have been conducted in South Korea. The purpose of this study was to examine effects of social distancing on the Public Bicycle Sharing System (PBSS) during the COVID-19 outbreak. We used the PBSS public dataset of Seoul, South Korea. Difference-in-differences (DID) analysis was used. In the DID approach, the 2 groups are distinguished based on designated year. Cases of PBSS use were observed in 2 time periods: pre- and post-strict social distancing in Seoul, Korea. Average PBSS usage per day doubled during 2019-2020 (30 697 vs 77 996, < .001). Commuters and weekend users increased during the social distancing period in 2020 compared with the same period in 2019. DID analysis showed statistically significant positive effects of high levels of social distancing on PBSS usage, commuters, weekend users, and new subscribers. In conclusion, social distancing during the COVID-19 outbreak increased outdoor physical activity. Meaningful outdoor physical activity during the COVID-19 pandemic can be safe from infection and psychologically stabilized as long as keeping meticulous physical distancing, such as hand hygiene, wearing facial masks, and surface cleaning of public resources.
新型冠状病毒病（COVID-19）爆发使全球陷入大流行状态。韩国对此采取了严格的筛选、隔离协议和接触者追踪措施。本研究旨在探讨 COVID-19 爆发期间社会隔离对公共自行车共享系统（PBSS）的影响。我们使用了韩国首尔的 PBSS 公共数据集。采用了差分法（DID）分析。在 DID 方法中，根据指定的年份将两组区分开来。在韩国首尔，观察到 PBSS 使用的 2 个时间段：严格社会隔离之前和之后。2019-2020 年期间，PBSS 的日平均使用量增加了一倍（30697 对 77996，<.001）。与 2019 年同期相比，2020 年社会隔离期间通勤者和周末使用者增加。DID 分析显示，高水平的社会隔离对 PBSS 使用、通勤者、周末使用者和新订户有统计学上显著的积极影响。总之，COVID-19 爆发期间的社会隔离增加了户外活动。只要保持细致的身体距离，如手部卫生、佩戴面部口罩和清洁公共资源表面，COVID-19 大流行期间有意义的户外活动可以安全地避免感染并在心理上得到稳定。
