2005

Transit accounts for just two percent of total travel in the U.S. One reason for low ridership is limited access; many individuals either live or work too far from a transit station. In developing transit connectivity solutions, researchers often employ a range of study instruments, such asstated-preference surveys, focus groups, and pilot programs. To better understand response to one innovative transit solution, the authors employed a number of research tools, including: a longitudinal survey, field test, and pilot program. The innovation examined was a commutercarsharing model, called...

Reducing Greenhouse Emissions and Fuel Consumption: Sustainable Approaches for Surface Transportation

Lipman, Timothy E.
2007

Climate change is rapidly becoming known as a tangible issue that must be addressed to avoid major environmental consequences in the future. Recent change in public opinion has been caused by the physical signs of climate change–melting glaciers, rising sea levels, more severe storm and drought events, and hotter average global temperatures annually. Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity, accounting for approximately 14 percent of total anthropogenic emissions globally and about 27 percent in the U.S.Fortunately...

Dynamics in Behavioral Response to Fuel-Cell Vehicle Fleet and Hydrogen Fueling Infrastructure

Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity. It accounts for approximately 14% of total anthropogenic emissions globally and about 27% in the United States. Growing concern regarding the impacts of climate change and greenhouse gas emissions has led to innovations in automotive and fueltechnology. However, behavioral response to the newest transportation technologies, such as hydrogen fuel cell vehicles (FCVs) and fueling infrastructure, is not well understood. This paper examines the results of an exploratory F-Cell...

North American Carsharing: A Ten Year Retrospective

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: An Exploratory Study

Susan Shaheen
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...

Carsharing's Impact on Household Vehicle Holdings: Results from a North American Shared-Use Vehicle Survey

2010

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 carownership. 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 oncarsharing’s impacts on household...

Bikesharing in Europe, the Americas, and Asia: Past, Present and Future

Growing concerns over global motorization and climate change have led to increasing interest in sustainable transportation alternatives, such as bikesharing (the shared use of a bicycle fleet). Since 1965, bikesharing has grown across the globe on four continents including: Europe, North America, South America, and Asia (including Australia). Today, there are approximately 100 bikesharing programs operating in an estimated 125 cities around the world with over 139,300 bicycles. Bikesharing’s evolution is categorized into three generations: 1) White Bikes (or Free Bike Systems); 2) Coin-...

How Public Education on Ecodriving Can Reduce Both Fuel Use and Greenhouse Gas Emissions

2012

Ecodriving, the concept of changing driving behavior and vehicle maintenance to impact fuel consumption and greenhouse gas (GHG) emissions in existing vehicles, has gained recent prominence in North America. One ecodriving strategy involves public education through Internet-based information dissemination. This paper presents the results of a controlled stated-response study conducted from June to December 2010 with approximately 100 University of California, Berkeley faculty, staff, and students, assessing the effectiveness of static ecodriving web-based information. A comparison of the...

Exploring the Future of Integrated Transportation Systems in the United States from 2030 to 2050: Application of a Scenario Planning Tool

Intelligent transportation systems (ITS) have primarily focused on systems management. To further improve connectivity and safety in the future, ITS might embrace a more holistic planning approach. While the future of ITS remains an open question, its evolution is closely linked to how the world evolves on many dimensions, social, political, economic, legal, and environmental. In this paper, the authors present results from four expert workshops. These consisted of an initial steering committee workshop (February 2011), two expert scenario-planning workshops (June 2011), and a final...

Evaluating the Public Perception of a Feebate Policy in California through the Estimation and Cross-Validation of an Ordinal Regression Model

Understanding the roots of policy perception can be critical for informing the design and implementation of innovative public policies; Feebates is one such innovative policy and in the context of new vehicles can be designed to offer buyers a rebate for the purchase of low-emission vehicles and a fee for the purchase of high-emission vehicles; Because feebates is a policy that directly impacts the consumer, understanding the dynamics of public perception, support, and opposition is important; This study explores the public perception of a feebate policy within California and evaluates the...
