Query: Understanding the Relationship between Social Distancing Policies,
  Traffic Volume, Air Quality, and the Prevalence of COVID-19 Outcomes in Urban
  Neighborhoods   In response to the COVID-19 pandemic, governments have implemented policies
to curb the spread of the novel virus. Little is known about how these policies
impact various groups in society. This paper explores the relationship between
social distancing policies, traffic volumes and air quality and how they impact
various socioeconomic groups. This study aims to understand how disparate
communities respond to Stay-at-Home Orders and other social distancing policies
to understand how human behavior in response to policy may play a part in the
prevalence of COVID-19 positive cases. We collected data on traffic density,
air quality, socio-economic status, and positive cases rates of COVID-19 for
each zip code of Salt Lake County, Utah (USA) between February 17 and June 12,
2020. We studied the impact of social distancing policies across three periods
of policy implementation. We found that wealthier and whiter zip codes
experienced a greater reduction in traffic and air pollution during the
Stay-at-Home period. However, air quality did not necessarily follow traffic
volumes in every case due to the complexity of interactions between emissions
and meteorology. We also found a strong relationship between lower
socioeconomic status and positive COVID-19 rates. This study provides initial
evidence for social distancing's effectiveness in limiting the spread of
COVID-19, while providing insight into how socioeconomic status has compounded
vulnerability during this crisis. Behavior restrictions disproportionately
benefit whiter and wealthier communities both through protection from spread of
COVID-19 and reduction in air pollution. Such findings may be further
compounded by the impacts of air pollution, which likely exacerbate COVID-19
transmission and mortality rates. Policy makers need to consider adapting
social distancing policies to maximize equity in health protection.
