We analyzed time-series changes in people's purpose-specific mobility characteristics owing to the COVID-19 pandemic in the Tokyo area of Japan, where only legally non-binding requests for self-restraint were enforced. A multiple regression analysis was conducted with the objective variable being the mobile population in the Tokyo area per 500 m square grid estimated from mobile spatial statistical data for 2 years from 10/01/2019 to 9/30/2021. This study period ranges from pre- to mid-pandemic. The explanatory variable was the number of buildings by type per 500 m square grid obtained from building statistical data to determine behavioral changes by mobility purpose. The analysis revealed that self-restraint was sustained until the middle of the COVID-19 pandemic in the Tokyo area regardless of the purpose of mobility and whether a state of emergency was declared.
我们分析了由于 COVID-19 疫情在日本东京地区实施的仅具有法律约束力的自我约束请求，人们的特定目的移动特征的时间序列变化。使用从 2019 年 10 月 1 日至 2021 年 9 月 30 日的移动空间统计数据估计的每 500 米平方网格的东京地区移动人口作为因变量，对多回归分析进行了分析。本研究期间包括大流行前到中期。解释变量是每 500 米平方网格的建筑类型数量，从建筑统计数据中获得，以确定按移动目的的行为变化。分析表明，无论移动目的和是否宣布紧急状态，东京地区的自我约束都持续到 COVID-19 大流行中期。
