2015

Business carsharing (or corporate carsharing) is a form of carsharing that enables commercial businesses to reduce or eliminate private vehicle eets typically maintained for business purposes. It may provide exclusive-use vehicles to clients that are shared among employees and departments or it may offer shared vehicles where the client accesses the vehicles as part of a larger carsharing eet (i.e., employees use the same vehicles that are shared by individuals and/or other business members) (Shaheen and Cohen, 2012).

2014

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...

2014

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

Susan Shaheen, PhD and Matt Christensen
2014

Shared-use mobilitythe shared use of a vehicle, bicycle or other low-speed modeis 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...

In the past ten years, passenger and goods movement transportation systems have evolved rapidly. Shared mobility providers are filling gaps in service and creating new markets for delivery; vehicle fleets continue to electrify; and pooled services are increasing vehicle occupancy. The uptake of innovative pooled services, as well as automation, promise to continue the trend of transformative change. As the private sector continues to advance, there is a great need for institutional flexibility in managing and coordinating all users of transportation infrastructure, particularly on...

Shared-ride services—transportation modes that allow riders to share a ride to a common destination—include various forms of ridesharing (carpooling and vanpooling); ridesplitting and taxisplitting; and microtransit. With the proliferation of smartphones and mobile Internet, it has become more convenient to share rides. Shared-ride services are having a transformative impact on many global cities by increasing vehicle occupancy through smartphone apps.

This chapter examines the characteristics and practices of ridesharing users in France. In May 2013, the authors surveyed members of BlaBlaCar, the largest online and app-based carpooling service in France, to analyze the sociodemographic characteristics and usage patterns of the respondents. The survey results identify correlations between socio-demographic characteristics and usage elements. Notably, users with a lower income level are more inclined to be passengers, while higher income users employ carpooling mainly as drivers. Students are shown to be more frequent users as well...
