By the year 2030, 57 million people will be over the age of 65 in the United States. Baby boomers drive approximately 17% more than other age groups and are active well past retirement. This article examines electric vehicle (EV) carsharing (short-term vehicle access) as a future alternative to vehicle ownership for older adults living on fixed incomes in a gated community to provide reduced-cost mobility and eliminate vehicle maintenance hassles.

Identification and Prioritization of Environmentally Beneficial Intelligent Transportation Technologies

Susan Shaheen, Ph.D, Troy Young, Ph.D, Daniel Sperling, Ph.D, Daniel Jordan, Ph.D, Thomas Horan, Ph.D
1998

This report presents a literature review on the energy and environmental impacts of Intelligent Transportation Systems (ITS) technologies, a presentation of the development of deployment/modeling scenarios, and a description of the modeling effort. The two-fold objective of this project was to: 1) identify those ITS technologies and systems that have positive environmental effects, and 2) rank order those technologies according to their energy and emission benefits and net reduction in VMT.

Car Sharing and Mobility Management: Facing New Challenges with Technology and Innovative Business Planning

Conrad Wagner and Susan Shaheen
1998

Based on the authors’ experience and knowledge of technical developments, several important factors for implementing carsharing in the future are recommended. The authors emphasize how carsharing organizations (CSOs) can be incorporated into multimodal mobility services by adopting new business strategies and advanced technologies. The authors identify exemplary CSOs that have already taken strides towards developing their organizations into intermodal mobility service providers.

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

Most automobiles 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.

Conformity Policy: Air Quality Impact Assessment for Local Transportation Projects

Randall Guensler, Ph.D, Susan Shaheen, Ph.D, Francisca Mar, Cameron Y. Yee
1998

The Conformity Rule, adopted in November 1993, by the U.S. Environmental Protection Agency (USEPA) under the requirements of Section 17(c)(4) of the Clean Air Act, establishes strict procedures for determining conformity of transportation plans to state air quality management plans. Conformity requirements apply to all transportation plans, programs, and projects, funded or approved under title 23 U.S.C. or the Federal Transit Act.

New Mobility: Using Technology and Partnerships To Create More Efficient, Equitable, and Environmentally Sound Transportation

1998

Land development and personal vehicle travel continue to outpace population growth. Efforts to manage this growth and the adverse impacts associated with it have been mostly ineffective. Promising technology solutions include telecommunications (telecommuting, electronic commerce, teleconferencing); small personal vehicles (electric bikes and neighborhood vehicles); and new “smart” transport modes (carsharing, “smart” paratransit). These technology-based options have the potential to be environmentally and economically superior to today’s car-dominated system.

Identification and Prioritization of Environmentally Beneficial Intelligent Transportation Technologies: Modeling Effort

Susan Shaheen, Ph.D, Troy Young, Ph.D, Daniel Sperling, Ph.D, Daniel Jordan, Ph.D, Thomas Horan, Ph.D
1999

This report deals with a project that involved a review of the environmental impacts of Intelligent Transportation Systems (ITS). The final phase of the project involved the development of a model that would be capable of quantifying the short-term environmental impacts of ITS applications along a typical transportation corridor. The report presents a model database with the modifications necessary to manipulate the data into a form suitable for use with INTEGRATION V2.0.

CarLink: A Smart Carsharing System

Susan Shaheen, PhD
1999

In this paper, the author outlines and summarizes the research stages of the CarLink I field test. The author also introduces the concept of transit-based “smart” carsharing and discusses how carsharing systems, such as CarLink, could change the way households use transportation, as well as reduce traffic congestion, air pollution, and government spending.

A Short History of Carsharing in the ’90s

Susan Shaheen, PhD, Daniel Sperling, and Conrad Wagner
1999

Updating a prior carsharing publication, this paper provides an extensive background to the international history of carsharing up to 1999, highlighting the reasons for which some organizations flourished and others faltered. Experiences of worldwide carsharing organizations (CSOs) are used to assess which factors are favorable to attaining innovative and economically viable operations and other organizational goals. The future prospects of international CSOs are explored based on trends in services offered, partnership management, and advanced technologies.

Pooled Cars

Susan Shaheen, PhD
1999

A condensed version of a previous paper, “A Short History of Carsharing in the 90s.” This paper provides an overview of North American, Asian, and European carsharing organizations and European innovations and advanced technologies. This paper also reflects on the lessons learned from international experiences. The author concludes with a list of conditions and recommendations for strategies that could be instrumental to carsharing success.
