Peer-to-Peer Car Sharing

OTREC is conducting a study of the launch of peer-to-peer car sharing in Portland by car sharing company Getaround. Peer-to-peer car sharing differs from traditional car sharing services in that the fleet is composed of privately owned vehicles made available by community members for others in the community to rent.  As part of a Federal Highway Administration (FHWA) grant, the study aims to understand the impact of the service on travel behavior. 

Selected car owners and renters in Portland, Oregon, are participating in the study by sharing information about their experience with Getaround.  OTREC is gathering data from Getaround trip information and participant surveys.  We want to be able to understand a number of factors about how peer-to-peer car sharing affects the travel behaviors and opportunities of both vehicle owners (those who are renting out their personal cars) and vehicle renters, including: 

  • How does the service impact participants' decisions about car ownership? 
  • Are transportation options and access improved as a result of car sharing? 
  • What are the factors that influence where and when participants choose to drive? 

Along with FHWA and Getaround, the City of Portland Bureau of Transportation and Oregon Department of Transportation are partners in this project, focusing on project and contract administration and management. You can learn more about the study, and find out about participating, here:
