Authors: Susan Shaheen, PhD, and Nelson Chan Published: March 2015 Abstract: Shared-use mobility includes carsharing, personal vehicle sharing (or peer-to-peer (P2P) carsharing), bikesharing, scooter sharing, shuttle services, ridesharing, and on-demand ride services. It can also include commercial delivery vehicles providing flexible goods movement. Shared-use mobility has had a transformative impact on many global cities by enhancing transportation accessibility while simultaneously reducing ownership of personal automobiles. In the context of carsharing and bikesharing, vehicles and bicycles are typically unattended, concentrated in a network of locations where the transaction of checking out a vehicle or bicycles is facilitated through information technology (IT) and other technological innovations. Usually, carsharing and bikesharing operators are responsible for the cost of maintenance, storage, parking, and insurance/fuel (if applicable). In the context of classic ridesharing (carpooling and vanpooling) and on-demand ride services, such as transportation network companies (TNCs), many of these providers employ IT to facilitate the matching of riders and drivers for trip making.

Authors: Lisa Rayle, Susan Shaheen, Ph.D., Nelson Chan, Danielle Dai, and Robert Cervero Date: November 2014 Abstract: The rapid growth of on-demand ride services such as uberX and Lyft, or “ridesourcing,” has prompted debate among policy makers and stakeholders. At present, ridesourcing’s usage and impacts are not well understood. Key questions include: how ridesourcing and traditional taxis compare with respect to trip types, customers, and locations served; whether ridesourcing complements or competes with public transit; and potential impacts on vehicle kilometers traveled. We address these questions using an intercept survey. In spring 2014, 380 complete surveys were collected from three ridesourcing “hot spots” in San Francisco. Survey results are compared with matched-pair taxi trip data and results of a previous taxi user survey. We also compared travel times for ridesourcing and taxis with those for public transit. The findings indicate ridesourcing serves a previously unmet demand for convenient, point-to-point urban travel. Although taxis and ridesourcing share similarities, the findings show differences in users and the user experience. Ridesourcing wait times are markedly shorter and more consistent than those of taxis, while ridesourcing users tend to be younger, own fewer vehicles and more frequently travel with companions. Ridesourcing, like taxis, appears to both substitute for and complement public transit; the majority of ridesourcing trips would have taken substantially longer if made by public transit. Impacts on overall vehicle travel are unclear. Future research should build on this exploratory study to further understand impacts of ridesourcing on labor, social equity, the environment, and public policy....

Authors: Susan Shaheen and Matt Christensen Date: June 06, 2014 Abstract: Shared-use mobilitythe shared use of a vehicle, bicycle or other low-speed modeis an innovative transportation solution that enables users to have short-term access to a transportation mode. In North America, shared-use mobility encompasses the submarkets of carsharing, bikesharing, ridesharing, on-demand ride services, scooter sharing, shuttle services, and other emerging industries. In October 2013, the University of California, Berkeley’s Transportation Sustainability Research Center (TSRC) hosted the inaugural Shared-Use Mobility Summit in San Francisco, California. The summit was a two-day event that facilitated a dialogue among nearly 300 participants representing close to 200 organizations. Participants included mobility providers, policymakers, governmental agencies, non-profits, technologists, academics, media, other stakeholders, and affiliated industries. One hundred and five (105) private companies attended the summit, and 62 governmental agencies were represented at the summit. Additionally, 44 academics from 17 universities participated. Of the 194 organizations represented, 26 were affiliated with carsharing, 16 with bikesharing, and 6 were associated with ridesharing and ondemand ride services or transportation network companies (TNCs). In recent years, economic, environmental, and social forces have quickly pushed shared-use mobility from the fringe to the mainstream, and its role in urban mobility has become a frequent point of discussion. The summit provided a diverse array of stakeholders the opportunity to advance the discussion by addressing key issues and helping to shape the future of shared-use mobility. This white paper, generously supported by the Rockefeller Foundation, discusses the state of the industry and trends in major shared-use mobility sectors: carsharing (including roundtrip, one-way, and peer-to-peer), bikesharing, ridesharing, and on-demand ride services (e.g., TNCs). The paper also...
