The COVID-19 pandemic and the resulting economic recession have negatively affected many people's social, and psychological health. Parks may have ameliorated the negative effects of the pandemic by creating opportunities for outdoor recreation. At the same time, other public activities were restricted due to the risk of disease transmissions. In our study, we seek to improve our understanding of how the COVID-19 pandemic impacts park visitations by performing a longitudinal study based on the aggregated telecommunication data. To do so, we introduce a novel approach based on the Gravity Model to understand, quantify and model the relationship between distance and the visitation patterns. Particularly, we aim to find out how the park visitation behavior changes post-pandemic and how this change of visitation varies for different socio-economic groups of visitors. Our results show that the park visitation pattern in Washington state (U.S.A) obeys the gravity law. Moreover, we show that, although parameters of the model may vary, the gravity model can still accurately estimate the visitation after applying socio-economic and spatial filters.
