Controlling human mobility is thought to be an effective measure to prevent the spread of the COVID-19 pandemic. This study aims to clarify the human mobility types that impacted the number of COVID-19 cases during the medium-term COVID-19 pandemic in the Osaka metropolitan area. The method used in this study was analysis of the statistical relationship between human mobility changes and the total number of COVID-19 cases after two weeks. In conclusion, the results indicate that it is essential to control the human mobility of groceries/pharmacies to between -5 and 5% and that of parks to more than -20%. The most significant finding for urban sustainability is that urban transit was not found to be a source of infection. Hence governments in cities around the world may be able to encourage communities to return to transit mobility, if they are able to follow the kind of hygiene processes conducted in Osaka.
控制人员流动被认为是预防新冠疫情传播的一项有效措施。本研究旨在阐明在大阪都会区新冠疫情中期影响新冠病例数的人员流动类型。本研究采用的方法是分析人员流动变化与两周后新冠病例总数之间的统计关系。总之，结果表明将食品杂货店/药店的人员流动控制在-5%至5%之间，将公园的人员流动控制在超过-20%是至关重要的。对于城市可持续性而言，最显著的发现是未发现城市公共交通是感染源。因此，如果世界各地的城市政府能够遵循大阪所采取的那种卫生流程，或许就能鼓励社区恢复公共交通出行。
