Bike Share's Impact on COVID-19 Transmission and Bike Share's Responses to COVID-19: A case study of Washington DC
share
Due to the wide-ranging travel restrictions and lockdowns applied to limit the diffusion of the SARS-CoV2 virus, the coronavirus disease of 2019 (COVID-19) pandemic has had an immediate and significant effect on human mobility at the global, national, and local levels. At the local level, bike-sharing played a significant role in urban transport during the pandemic since riders could travel outdoors with reduced infection risk. However, based on different data resources, this non-motorized mode of transportation was still negatively affected by the pandemic (i.e., relative reduction in ridership). This study has two objectives: 1) to investigate the impact of the COVID-19 pandemic on the numbers and duration of trips conducted through a bike-sharing system – the Capital Bikeshare in Washington, DC, USA; and 2) to explore whether land use and household income in the nation's capital influence the spatial variation of ridership during the pandemic. Towards realizing these objectives, this research looks at the relationship between bike sharing and COVID-19 transmission as a two-directional relationship rather than a one-directional causal relationship. Accordingly, this study models i) the impact of COVID-19 infection numbers and rates on the use of the Capital Bikeshare system and ii) the risk of COVID-19 transmission among individual bike-sharing users. In other words, we examine i) the cyclist's behavior as a function of the COVID-19 transmission evolution in an urban environment and ii) the possible relationship between the bike share usage and the COVID-19 transmission through adopting a probabilistic contagion model. The findings show the risk of using a bike-sharing system during the pandemic and whether bike sharing remains a healthier alternative mode of transportation in terms of infection risk.
