Time-Series Clustering for Home Dwell Time during COVID-19: What Can We Learn from It?

Abstract: In this study, we investigate the potential driving factors that lead to the disparity in the time-series of home dwell time in a data-driven manner, aiming to provide fundamental knowledge that benefits policy-making for better mitigation strategies of future pandemics. Taking Metro Atlanta as a study case, we perform a trend-driven analysis by conducting Kmeans time-series clustering using fine-grained home dwell time records from SafeGraph. Furthermore, we apply ANOVA (Analysis of Variance) coupled with pos… Show more

“…Following the work by X. Huang, Li, Lu, et al (2020), representativeness is defined as the ratio between the median daily device count and the CBG's population (from the American Community Survey [ACS] 2020;2014-2018. As shown in Figure 3, the representativeness of one MSA differs from that of another, with the Dallas MSA (Figure 3D) showing the highest representativeness and the San Francisco MSA (Figure 3K) showing the lowest.…”

“…Following the design by X. Huang, Li, Lu, et al (2020), we included and recoded twenty-one demographic and socioeconomic variables from five major categories: (1) economic status; (2) race and ethnicity; (3) gender, age, and household type; (4) education; and (5) transportation. Numerous studies have proven that these variables are, to some degree, associated with participation in out-of-home activities (Kuppam and Pendyala 2001;Farber and P aez 2009;Morency et al 2011).…”

“…These are important factors to be taken into account since the Centers for Disease Control and Prevention specifically highlights via its famous 6-feet-15-minutes rule for a close contact 23 . While recent studies have considered the distribution of trips by dwell time 24 and crowd density based on non-residential square footage 25 at certain trip destinations, these have been studied in isolation as time series trends but not as a comprehensive measure of exposure.…”
