Title:

On-Demand Ridesourcing Has Reduced Per-Capita Vehicle Registrations and Gasoline Use in U.S. States

Abstract:

On-demand mobility services have the potential to influence vehicle adoption, travel patterns, and environmental outcomes, but there is limited knowledge on whether and to what extent these changes occur in practice. The authors examine the relationship between Uber/Lyft market launch dates in U.S. cities and per-capita vehicle ownership, use, and emissions at the state level for the period 2005-2015. Specifically, they develop a difference-in-difference econometric model using data on new vehicle registrations and vehicle distance traveled from the Department of Transportation; Uber and Lyft entry timing in U.S. cities; and emissions estimates from the Environmental Protection Agency. The authors find that, on average, a state’s per-capita vehicle registrations are 2.8% lower during the first two years following entry and 4.6% lower afterward than if on-demand mobility services had not entered the state. During the examined period, this represents an average decrease of 3.5% overall. On average, vehicle registrations reduce 0.05% for every 1% of the state’s population that gains access to on-demand mobility services. The authors do not find statistically significant effects of market entry on vehicle miles traveled, but entry is associated with statistically significant decreases in the emissions of ammonia (2.5%), nitrogen oxides (3.1%), and volatile organic compounds (4.1%).
