Carsharing and Station Cars in Asia: Overview of Japan and Singapore

Matt Barth, Susan Shaheen, PhD, Tuenjai Fukuda, and Atsushi Fukuda

In recent years there has been significant worldwide activity in shared-use vehicle systems (I.e., carsharing and station cars). Much of this activity is taking place in Europe and North America; however, there has also been significant activity in Asia, primarily in Japan and Singapore. This paper examines the latest shared-use vehicle system activities in both of these countries, beginning with an historical review followed by an evaluation of their current systems. Overall there are several well-established systems in Japan (approximately 18 systems, 150 vehicles, 3000 members)...

Carsharing Continues to Gain Momentum

Susan Shaheen, PhD

With auto ownership and fuel costs rising, people everywhere are seeking alternatives to private vehicle ownership. Carsharing (or short-term vehicle rentals) provides such an alternative through hourly rates and subscription-access plans, especially for individuals and businesses in major cities with good access to other transportation modes, such as transit and carpooling. The principle of carsharing is simple: individuals gain the benefits of private vehicle use without the costs and responsibilities of ownership. People involved in this typically join an organization that...

Growth in Worldwide Carsharing: An International Comparison

Susan Shaheen, PhD and Adam Cohen

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, it did not become popularized until the early 1990s. For nearly 20 years, there has been growing worldwide participation in carsharing. Today, carsharing operates in approximately 600 cities around the world, in 18 nations, and on four continents. Malaysia is operating a carsharing pilot, with a planned launch in 2007. Another...

Carsharing and the Built Environment: Geographic Information System-Based Study of One U.S. Operator

Tai Stillwater, Patricia Mokhtarian, and Susan Shaheen, PhD

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...

North American Carsharing: A Ten-Year Retrospective

Susan Shaheen, PhD, Adam Cohen, and Melissa Chung

Carsharing organizations (or short-term auto use) provide members access to a fleet of shared vehicles on an hourly basis, reducing the need for private vehicle ownership. This paper reflects a ten-year retrospective of carsharing in Canada and the United States (U.S.), including resultsfrom a 2008 operator survey. Since 1994, a total of 50 carsharing programs have been deployed in North America - 33 are operational, and 17 are defunct. As of July 1, 2008, there were 14 active programs in Canada and 19 in the U.S., with approximately 319,000 carsharing memberssharing over 7,500 vehicles in...

Demand for Carsharing Systems in Beijing, China

Susan Shaheen, PhD and Elliot Martin

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...

Impact of Carsharing on Household Vehicle Holdings: Results from a North American Shared-use Vehicle Survey

Elliot Martin, Susan Shaheen, PhD, and Jeffrey Lidicker

Carsharing has grown considerably in North America during the past decade and has flourished within metropolitan regions across the United States and Canada. The result has been a new transportation landscape, which offers urban residents an alternative to automobility without car ownership. As carsharing has expanded, there has been a growing demand to understand its environmental impacts. This paper presents the results of a North American carsharing member survey (N = 6,281). The authors establish a “before-and-after” analytical design with a focus on carsharing’s impacts on...

Carsharing Parking Policy: Review of North American Practices and San Francisco, California, Bay Area Case Study

Susan Shaheen, PhD, Adam Cohen, and Elliot Martin, PhD

Carsharing provides users access to a shared vehicle fleet for short-term use throughout the day, reducing the need for private vehicles. The provision of on-street and public off-street parking dedicated to carsharing is an important policy area confronting public agencies. As of July 2009, approximately 377,600 individuals were carsharing members in North America in about 57 metropolitan areas. Seventeen jurisdictions, one state (California), and eight public transit operators in North America have formal and informal carsharing parking policies, pilot projects, and proposed...
