Shared mobility and urban form impacts: a case study of peer-to-peer (P2P) carsharing in the US

Susan Shaheen, PhD, Elliot Martin, PhD, and Mikaela Hoffman-Stapleton

This paper advances the understanding of peer-to-peer (P2P) carsharing within the broader context of shared mobility and its connection to the built environment in the US through a survey conducted in 2014 (n = 1,151). Eleven per cent of respondents used carpooling/ridesharing more, and 19% avoided a vehicle purchase due to P2P vehicle access in urban areas. Nevertheless, P2P carsharing has the potential to operate in a range of land-use environments and could be an important strategy to further deemphasize car ownership. Additionally, as the deployment of automated vehicles (AVs) is...

Chapter 13 - Sharing strategies: carsharing, shared micromobility (bikesharing and scooter sharing), transportation network companies, microtransit, and other innovative mobility modes

Susan Shaheen, PhD, Adam Cohen, Nelson Chan, and Apaar Bansal

Shared mobility—the shared use of a vehicle, bicycle, or other mode—is an innovative transportation strategy that enables users to gain short-term access to transportation modes on an “as-needed” basis. It includes various forms of carsharing, bikesharing, scooter sharing, ridesharing (carpooling and vanpooling), transportation network companies (TNCs), and microtransit. Included in this ecosystem are smartphone “apps” that aggregate and optimize these mobility options, as well as “courier network services” that provide last mile package and food delivery. This chapter describes...

Peer-to-peer (P2P) carsharing is an innovative approach to vehicle sharing in which vehicle owners temporarily rent their personal automobiles to others in their surrounding area. P2P carsharing belongs to the larger sharing economy, an economic model premised on the notion of collaborative consumption as opposed to ownership. This study examines current public perception of P2P carsharing and potential market characteristics through an intercept survey conducted in the San Francisco Bay Area. Three hundred respondents from 14 locations in San Francisco (N=150) and Oakland (N=150) were...
