Health Impacts of COVID-19 through the Changes in Mobility

Abstract

Understanding the wider effects of the COVID-19 pandemic on public health is needed to respond sufficiently to the impacts and facilitate recovery. We studied the secondary health impacts of COVID-19 through the changes in transportation using a ripple effect mode. Three ripples are defined to reflect the impacts of COVID-19 on (1) transportation and the systems behind it, (2) transportation-related health risk factors, and (3) public health. COVID-19 impacts on transportation are synthesized through six areas: transportation demand, transportation mode, traffic safety, land use and built environment, transportation jobs, and transportation equity. These changes are further associated with decreased transportation-related air pollution, greenhouse gases, noise, heat, and stress. Higher rates of road casualties were observed in the area of COVID-19. Social exclusion and limitations in accessibility to healthcare and healthy food were identified as negative consequences of changes in transportation. There are uncertainties in the rate of active transportation (i.e., walking and cycling) and related crashes that require further investigation. The findings of this study uncover the complex and relatively unknown impacts of COVID-19 on public health through changes in transportation.
