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 paper 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. The authors conducted a study of the response to the EV carsharing concept in a senior community in Northern California, between Winter 2009 and...

One-Way Carsharing's Evolution and Operator Perspectives from the Americas

Classic roundtrip carsharing has been documented as a strategy to reduce car ownership and vehicle miles/kilometers traveled in urban areas. The expansion of carsharing and other forms of shared-use mobility have led to a growing interest in understanding the latest models. In recent years, one-way carsharing has gained momentum across the globe with 18 operators providing services in ten countries worldwide. One-way carsharing does not require its users to return the vehicle to the same location from which it was accessed (in contrast to roundtrip carsharing). Users typically pay by the...

Evolution of E-Mobility in Carsharing Business Models

Carsharing continues to grow worldwide as a powerful strategy to provide an alternative to solo driving. The viability of electric vehicles, or EVs, has been exam-ined in various carsharing business models. Moreover, new technologies have given rise to electromobility, or e-mobility, systems. This paper discusses the evolution of e-mobility in carsharing business models and the challenges and opportunities that EVs present to carsharing operators around the world. Operators are now anticipating in-creased EV proliferation into vehicle fleets over the next 5-10 years as technology,...

Generic time- and method-interdependencies of empirical impact-measurements: A generalizable model of adaptation-processes of carsharing-users' mobility-behavior over time

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. However, the quantification of this potential is complex, and few studies have analyzed the fundamental impacts of the chosen measurement-methodology on the results of...

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. We review both...

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. The authors examine the policy context and regulatory arena in which ITS technologies are...

Conformity Policy: Air Quality Impact Assessment for Local Transportation Projects

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. The Conformity Rule requires that transportation planning agencies apply transportation demand and emission models to demonstrate that transportation...

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. Yet each has its...

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. The authors describe the difficulties and challenges that were faced in the project, which ultimately led to the...
