2016

Car2go is currently the largest carsharing operator in the world, with a presence in nine countries and nearly 30 cities. It operates as a one-way instant access carsharing system within a pre-defined urban zone. Members can find an unoccupied parked vehicle, access it immediately, and use it to meet their local travel needs. As long as the vehicle is parked within the operating zone, users...

Transit-Based Smart Parking in the San Francisco Bay Area, California: Assessment of User Demand and Behavioral Effects

Rodier, Caroline J.
Shaheen, Susan A.
Eaken, Amanda M.
2005

This paper presents early findings from an application of advanced parking technologies to increase effective parking capacity at a transit station during the first half of 2004 in the San Francisco Bay Area (CA). It begins with an extensive review of the literature related to transit-based smart parking management systems to illustrate the range of system configurations and their potential travel, economic, and environmental effects. Two important conclusions from this review are: (1) lack of parking spaces at transit stations may be a significant constraint to transit use and (2) pre-...

Understanding Carsharing Risk and Insurance Claims in the United States

2016

Carsharing offers consumers short-term access to vehicles, which facilitates better mobility and reduces the need for personal vehicle ownership. Carsharing does not require consumers to have automobile insurance. Instead, carsharing operators insure their members and are responsible for the risks and liabilities associated with vehicle use. Carsharing operators are burdened with obtaining cost-effective insurance under a usage model that lacks massive actuarial data and analysis. This study analyzes 28 operator years of trips and claims data from six carsharing operators in the United...

Shared Mobility and Urban Form Impacts: A Case Study of Peer-to-Peer (P2P) Carsharing in the US

Shaheen, Susan

Hoffman-Stapleton, Mikaela
2019

This paper advances the understanding of peer-to-peer (P2P) carsharing within the broader context of shared mobility and its connection to the built environment in the US through a survey conducted in 2014 (n = 1,151). Eleven per cent of respondents used carpooling/ridesharing more, and 19% avoided a vehicle purchase due to P2P vehicle access in urban areas. Nevertheless, P2P carsharing has the potential to operate in a range of land-use environments and could be an important strategy to further deemphasize car ownership. Additionally, as the deployment of automated...

Demand for Carsharing Systems in Beijing, China: An Exploratory Study

Shaheen, Susan A.
Martin, Elliot
2010

Rising auto ownership in China brings significant urban and environmental challenges. Since China is still in the early stages of motorization, there are opportunities to introduce alternatives to personal vehicle ownership. The authors conducted a survey with 800 Beijing residents, collecting data on transportation patterns, automobile ownership, environmental attitudes, and carsharing response. Fifteen of those participants were selected to complete an in-depth questionnaire discussing how they would use carsharing services. This paper assesses the potential for carsharing systems within...

Growth in Worldwide Carsharing: An International Comparison

Shaheen, Susan A.
Cohen, Adam P.
2007

Carsharing (or short-term auto use) provides a flexible alternative that meets diverse transportation needs across the globe while reducing the negative impacts of private vehicle ownership. Although carsharing appeared in Europe between the 1940s and 1980s, the concept did not become popularized until the early 1990s. For nearly 20 years, worldwide participation in carsharing has been growing. Today, carsharing operates in approximately 600 cities around the world, in 18 nations and on 4 continents. Approximately 348,000 individuals share nearly 11,700 vehicles as part of organized...

Chapter 12: Shared Micromobility Policy and Practices in the United states

Shaheen, Susan
2021

Shared micromobility has the potential to offer communities an array of individual and community benefits, such as increased mobility, greater environmental awareness, and increased use of active transportation and non-vehicular modes. With careful planning and public policy, micromobility can also enhance accessibility and quality of life in cities. This chapter dis-cusses the growth of shared micromobility, its impacts on users and communities, and policy considerations for managing the potential adverse impacts of shared micromobility on curbspace management. This chapter is...

Shared Ride Services in North America: Definitions, Impacts, and the Future of Pooling

Shaheen, Susan
Cohen, Adam
2018

Shared ride services allow riders to share a ride to a common destination. They include ridesharing (carpooling and vanpooling); ridesplitting (a pooled version of ridesourcing/transportation network companies); taxi sharing; and microtransit. In recent years, growth of Internet-enabled wireless technologies, global satellite systems, and cloud computing - coupled with data sharing – are causing people to increase their use of mobile applications to share a ride. Some shared ride services, such as carpooling and vanpooling, can provide transportation, infrastructure, environmental...
