The purpose of this article is to advance empirical sustainability-evaluations of carsharing-systems. Carsharing, a frequently cited example of a product–service system (PSS), is currently morphing from a niche into a mainstream mode of transportation. Carsharing has the potential to provide a more sustainable mobility-option compared to private car usage, for example by reducing the overall motor-vehicle traffic in cities.

Good Practices for Local Governments and Private Companies Driving Change Together in Urban Mobility: Lessons Learned from One-Way Carsharing

Transforming urban mobility requires integrating public with private services into a single transportation system. Local governments and private companies face the challenge of how to coordinate themselves. An emblematic example is one-way carsharing (shared use of a fleet of vehicles that are typically free-floating throughout an urban area). Surprisingly, good practices for public and private players driving this change remain relatively undocumented. This paper proposes a systematic and balanced public-private approach to foster transportation innovation management.

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

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.

Conformity Policy: Air Quality Impact Assessment for Local Transportation Projects

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

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

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.

Pooled Cars

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.

Carsharing: Niche Market or New Pathway?

The premise of carsharing is simple.  Households access, as needed, a fleet of shared-use vehicles.

Dynamics in Behavioral Adaptation to a Transportation Innovation: A Case Study of Carlink–A Smart Carsharing System

Susan Shaheen, PhD
1999

Most trips in U.S. metropolitan regions are drive-alone car trips, an expensive and inefficient means of moving people. A more efficient system would allow drivers to share cars. Such a system is often less convenient for travelers, but convenience can be enhanced by deploying “smart” technologies in concert with shared-use vehicles and transit.
