人流ビッグデータで見たCOVID-19流行後のグリーンインフラや観光地利用の変化 (Human mobility flow dataset reveals changes in green infrastructure and tourist attractions use by people before and during the COVID-19 pandemic) in Japanese

Journal of The Japanese Institute of Landscape Architecture, 2022

Due to the COVID-19 pandemic, various behavioral restrictions and behavioral changes have been required worldwide, and people's movements have changed significantly. In this study, we investigated how the usage patterns of citizens and tourists changed before and after the COVID-19 pandemic in six representative public parks and tourist attractions in Kanazawa City depending on the purpose of their maintenance, internal facilities, and location. For the analysis data, we used location data recorded by the GPS built into the smartphones of individuals who stayed in Kanazawa City during the first half of May in each of 2019, 2020, and 2021. The results showed that the number of visitors, time of use, and place of estimated residence differed greatly among the six study sites. In particular, the number of visitors (especially tourists from outside the prefecture) at tourist attractions decreased remarkably in 2020 during the pandemic compared to 2019 before the pandemic. On the other hand, the number of visitors increased in the seaside comprehensive park, and the time of use by nearby residents changed in the riverside park, indicating that the pandemic created new patterns of green space use.
