Peer-To-Peer (P2P) Carsharing: Exploring Public Perception and Market Characteristics in the San Francisco Bay Area

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...

Carsharing in Europe and North American: Past, Present, and Future

Shaheen, Susan
Sperling, Daniel
Wagner, Conrad
1998

Most cars carry one person and are used for less than one hour per day. A more economically rational approach would be to use vehicles more intensively. Carsharing, in which people pay a subscription plus a per-use fee, is one means of doing so. Carsharing may be organized through affinity groups, large employers, transit operators, neighborhood groups, or large carsharing businesses. While carsharing does not offer convenient access to vehicles, it does provide users with a large range of vehicles, fewer ownership responsibilities, and less cost (if vehicles are not used intensively)....

Casual Carpooling in the San Francisco Bay Area: Understanding User Characteristics, Behaviors, and Motivations

Shaheen, Susan, PhD
Chan, Nelson
Gaynor, Theresa
2016

Casual carpooling is an informal form of commuter ridesharing operating in Washington, D.C.; Houston, Texas; and San Francisco, California. In contrast to new forms of shared-use mobility, casual carpooling has been in existence for over 30 years and uses no information communication technology, and is entirely run informally by its users. Researchers have been fascinated by this phenomenon and have conducted studies in the past, but there remains a lack of up-to-date quantitative data. This study examines the motivations and behaviors of casual carpoolers in the San Francisco Bay Area to...

Shared Mobility: The Potential of Ride Hailing and Pooling

Shaheen, Susan, PhD
2018

Shared mobility with pooled rides is the linchpin for leveraging vehicle automation and electrification to reduce congestion and emissions and to create livable urban communities. The sharing of rides is older than horse-and-buggy travel. Recent innovations make sharing easier, more convenient, and more efficient. Innovative mobility services premised on pooling can lower travel costs, mitigate congestion, and reduce greenhouse gas emissions. They also offer travelers more mobility choices between the traditional bookends of auto ownership and public transit. While the realm of shared...

Online and App-Based Carpooling in France: Analyzing Users and Practices—A Study of BlaBlaCar

Shaheen, Susan, PhD
Stocker, Adam
Mundler, Marie
2017

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. These...

Understanding the Diffusion of Public Bikesharing Systems: Evidence from Europe and North America

Parkes, Stephen
Mardsen, Greg
Shaheen, Susan, PhD
Cohen, Adam
2013

Since the mid-2000s, public bikesharing (also known as ‘‘bike hire’’) has developed and spread into a new form of mobility in cities across the globe. This paper presents an analysis of the recent increase in the number of public bikesharing systems. Bikesharing is the shared use of a bicycle fleet, which is accessible to the public and serves as a form of public transportation. The initial system designs were pioneered in Europe and, after a series of technological innovations, appear to have matured into a system experiencing widespread adoption. There are also signs that the policy of...

3rd Annual Shared Micromobility State of the Industry Report

North American Bikeshare & Scooter Share Association (NABSA)
2021

NABSA is pleased to present our third annual Shared Micromobility State of the Industry Report. In 2021, the industry continued to respond to the COVID-19 pandemic with shared micromobility filling critical gaps in essential mobility. The industry continued to rebound and demonstrate tremendous resilience, with the number of systems growing past pre-pandemic levels. This report tracks that progress and the trends that are emerging in the industry. To inform this report, we have collected data across a wide variety of topics, including ridership metrics, user profiles, employment, equity,...
