论文摘要
这项研究调查了COVID-19的感染病例和两个非强制性锁定对东京都市地区人类流动性的影响。利用每小时5亿美元的每小时人口的数据5亿美元的牢房及其城市级别的居留性，我们表明，当感染病例增加时，长途旅行或前往拥挤的地方的旅行会大大减少。尽管第二个锁定效果较差，但两个锁定的结果也相同。因此，日本的非强制性锁定以与感染病例增加的方式影响流动性。这意味着他们被接受为有签约Covid-19的风险的人的警报触发因素。
This study investigates the influence of infection cases of COVID-19 and two non-compulsory lockdowns on human mobility within the Tokyo metropolitan area. Using the data of hourly staying population in each 500m$\times$500m cell and their city-level residency, we show that long-distance trips or trips to crowded places decrease significantly when infection cases increase. The same result holds for the two lockdowns, although the second lockdown was less effective. Hence, Japanese non-compulsory lockdowns influence mobility in a similar way to the increase in infection cases. This means that they are accepted as alarm triggers for people who are at risk of contracting COVID-19.
