Transportation Energy Futures Series: Effects of Travel Reduction and Efficient Driving on Transportation: Energy Use and Greenhouse Gas Emissions

Abstract

This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a U.S. Department of Energy (DOE)-sponsored multi-agency project initiated to identify underexplored strategies for abating greenhouse gases and reducing petroleum dependence related to transportation. The project was designed to consolidate existing transportation energy knowledge, advance analytic capacity-building, and uncover opportunities for sound strategic action.Transportation currently accounts for 71% of total U.S. petroleum use and 33% of the nation's total carbon emissions. The TEF project explores how combining multiple strategies could reduce GHG emissions and petroleum use by 80%. Researchers examined four key areas -lightduty vehicles, non-light-duty vehicles, fuels, and transportation demand -in the context of the marketplace, consumer behavior, industry capabilities, technology and the energy and transportation infrastructure. The TEF reports support DOE long-term planning. The reports provide analysis to inform decisions about transportation energy research investments, as well as the role of advanced transportation energy technologies and systems in the development of new physical, strategic, and policy alternatives.In addition to the DOE and its Office of Energy Efficiency and Renewable Energy, TEF benefitted from the collaboration of experts from the National Renewable Energy Laboratory and Argonne National Laboratory, along with steering committee members from the Environmental Protection Agency, the Department of Transportation, academic institutions and industry associations.

Numerous transportation strategies are directed at reducing energy use and greenhouse gas (GHG) emissions by changing the behavior of individual drivers or travelers. These behavioral changes may have the effect of reducing travel, shifting travel to more efficient modes, or improving the efficiency of existing travel. This report reviews and summarizes the literature on relationships between these strategies and transportation-related energy use and GHG emissions. ContractThe primary objectives of this report are to examine how changes to travel behavior can reduce transportation energy use and discuss the potential for federal actions t...

Estimated Bounds and Important Factors for Fuel Use and Consumer Costs of Connected and Automated Vehicles

“…How this could be implemented and how many users would be willing to share rides are very uncertain. Brown et al (2014) cited a review of ridesharing programs (Porter et al 2013) and estimated that ridesharing could reduce total VMT by as much as 12%. Porter et al noted that historically, ridesharing programs have had little impact on VMT.…”

“…Porter et al noted that historically, ridesharing programs have had little impact on VMT. However, they further observed that according to the FHWA, average vehicle occupancy was about 1.6-1.7 persons and less than 1.1 persons for work trips, and concluded that ridesharing could potentially reduce VMT by a large amount (FHWA 2011, Porter et al 2013.…”

Um procedimento baseado na acessibilidade para a concepção de Planos Estratégicos de Mobilidade Urbana: o caso do Brasil

“…Caracterização da mobilidade sustentável e seus atributos A medição tradicional da mobilidade ressalta, principalmente, a quantidade de viagens, valorizando modalidades mais rápidas, e, consequentemente, o uso de automóveis (Litman, 2015 d. Justa socialmente: apresenta qualidade de serviço para todos e se realiza com tempos aceitáveis, principalmente, nas viagens a trabalho e ao ensino, proporcionando condições das pessoas desfrutarem outras atividades e oportunidades, fundamentais para a qualidade de vida e o bem estar social (Welch & Mishra, 2013); e. Verde: pressupõe o compromisso com viagens baseadas em meios de transportes amigáveis ambientalmente, com energia limpa e em condições focadas na redução da poluição atmosférica, sonora, das emissões de gases de efeito de estufa (Porter et al, 2013).…”

Modelling Travel Demand Management Measurements towards Travel Behaviour with Psycho-Social, Trip Chain Attributes and Quality of Life: A Conceptual Paper

“…Travel choice and mode are more often than not influenced by travel time and cost [26]. The costs perceived by users have monetary or out-of-pocket costs and the value of time spent travelling [27].…”
