From: Multiscale heterogeneous optimal lockdown control for COVID-19 using geographic information
Visualization of the lockdown policies for different types of activity sites and for five representative subregions in the Phoenix MSA. Higher values correspond to lockdowns that are more restrictive. The populations of the five representative subregions, listed in decreasing order, are: Phoenix (\(1.67 \times 10^{6}\)), Mesa (\(5.46 \times 10^{5}\)), Chandler (\(2.67 \times 10^{5}\)), Tempe (\(1.82 \times 10^{5}\)), and Cave Creek (\(6.20 \times 10^{3}\)). For all activity sites, we observe that the average lockdown value is higher for subregions with larger populations. We also note that the lockdown value is significantly higher for certain activity sites due to their large demand rates.
