Despite lower user costs, only 20% to 40% of transportation network company (TNC) users select a pooled, or shared, ride option. Why are existing TNC users not selecting the pooled option or using TNCs to connect to public transit, and what role do built environment features and incentives play in their decision? This study explores the factors that influence TNC user decisions through a multi-method approach comprising photovoice small group discussions and a workshop. Between March 2021 and May 2021, 15 San Francisco Bay Area TNC users shared photographs they took of TNC pick-up...

The use of carsharing vehicles over a period of 16 months in 2006-07 was compared to built environment and demographic factors in this GIS-based multivariate regression study of an urban U.S. carsharing operator. Carsharing is a relatively new transportation industry in which companies provide members with short-term vehicle access from distributed neighborhood locations. The number of registered carsharing members in North America has doubled every year or two to a current level of approximately 320,000. Researchers have long supposed that public transit access is a key factor driving...

Over the past three decades, carsharing has grown from a collection of local grassroots organizations into a worldwide industry.

The next generation of shared-use vehicle services could overcome such expansion barriers as capital costs and land use by incorporating new concepts like personal vehicle sharing. Personal vehicle sharing provides short-term access to privately-owned vehicles. As of May 2012, there were 33 personal vehicle sharing operators worldwide, with 10 active or in pilot phase,...
