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. The term shared mobilityincludes various forms of carsharing, bikesharing, ridesharing (carpooling and vanpooling), and on-demand ride services. It can also include alternative transit services, such as paratransit, shuttles, and private transit services, called microtransit, which can supplement fixed-route bus and rail services. With many new options for mobility emerging, so...

TRB’s E-Circular 210: Multimobility and Sharing Economy: Shaping the Future Market Through Policy and Research Multimodal explores the results of a workshop that focused on new developments in the shared-mobility sphere, the use of smartphones in pushing the goal of shared mobility forward, and on rural and suburban mobility problems. It also raised the issue of equity for paratransit options in relation to innovative transportation modes and touched on strategies that could foster an environment of increased inclusion. Automated vehicles also were considered at the workshop, namely...

Researchers at the Transportation Sustainability Research Center (TSRC), UC Berkeley in partnership with Zipcar conducted a survey to better understand the impact that carsharing has on college member travel behavior, vehicle holdings and driving, quality of life, and transportation expense savings. The survey design was conducted as a joint effort among TSRC, Zipcar, and university representatives. The college/university carsharing market is a unique environment for both carsharing users and operators. Due to the particular living arrangements and travel needs of college members,...

Peer-to-peer (P2P) carsharing employs privately owned vehicles made temporarily available for shared use by an individual or members of a P2P carsharing network. Expenditures, such as insurance, are generally covered by the P2P operator during the access period. In exchange for providing the service, operators keep a portion of the usage fee. Members can access vehicles through a direct key or combination transfer from the owner or through operator-installed technology that enables “unattended access.” Although P2P carsharing is more commonplace in the United Kingdom, Netherlands,...

Shared mobility services have now become firmly integrated into urban transportation systems across the globe. Carsharing, bikesharing, ridesourcing or transportation network companies (TNCs), and other systems now offer urban travelers access to transportation services that had long been previously only possible through personal vehicle ownership. Carsharing is arguably the pioneer mode of the sharing economy, given it ushered in a new way of thinking and access to the private automobile in the 20th century. Since its North American inception in Montreal in...
