The effectiveness of urban mobility restriction policies on the spatio-temporal pattern of COVID-19 incidence in Balikpapan City

Abstract

In 2020, the first year of the Covid-19 pandemic provided a valuable experience for city policymakers. As one of the epicenters of Covid-19 in East Kalimantan, Balikpapan City has also made various efforts to suppress the transmission of Covid-19, mainly focused on minimizing the urban mobility rate. This study was conducted to track the effectiveness of policies applied to the number of Covid-19 active cases in Balikpapan City. This study performs the Spatio-temporal Getis-Ord Gi* statistic to determine the characteristics of changes in the concentration of the Covid-19 active cases and calculate the correlation of the time data. The results showed that during the first year of pandemic and application of the travel restriction policy, hotspots were always formed in the potential economic sub-districts, which became the business center of Balikpapan City. In addition, the implementation of significant travel restriction policies has a strong correlation with the tendency to decrease the active case number of COVID-19 in each policy issue date.
