Barriers to the Increased Adoption of Fuel Efficiency Technologies in the North American On-Road Freight Section Roeth, M., Kircher, D., Smith, J., Swim, R. 7/29/2013 Reports

North American Council for Freight Efficiency, Cascade Sierra Solutions, Eugene, Oregon

Analysis of market barriers to the widespread adoption of off-the-shelf efficiency technologies, including limited availability, lack of credible information about benefits, and uncertainty about the length of payback period.

ORNL Operations Best Practices Guide: Idle Reduction Curran, S., Settles, K; Keel-Blackmon, K. 3/15/2013 Brochures & Fact Sheets

Oak Ridge National Laboratory, Oak Ridge, Tennessee; East Tennessee Clean Fuels Coalition, Knoxville, Tennessee

The Oak Ridge National Laboratory Sustainable Campus Initiative, working with the local DOE Clean Cities program, has created an idle reduction guide that explains the benefits of reducing idling. Included in the guide is a collection of vehicle manufacturer recommendations that will help improve vehicle fuel economy and reduce tailpipe emissions.

Transportation Energy Futures Series: Freight Transportation Modal Shares: Scenarios for a Low-Carbon Future Brogan, J. J.; Aeppli, A. E.; Beagan, D. F.; Brown, A.; Fischer, M. J.; Grenzeback, L. R.; McKenzie, E.; Vimmerstedt, L.; Vyas, A. D.; Witzke, E. 3/1/2013 Reports

Cambridge Systematics, Cambridge, Massachusetts and Argonne National Laboratory, Argonne, Illinois

Truck, rail, water, air, and pipeline modes each serve a distinct share of the freight transportation market. The current allocation of freight by mode is the product of technologic, economic, and regulatory frameworks, and a variety of factors -- price, speed, reliability, accessibility, visibility, security, and safety -- influence mode. Based on a comprehensive literature review, this report considers how analytical methods can be used to project future modal shares and offers insights on federal policy decisions with the potential to prompt shifts to energy-efficient, low-emission modes. There are substantial opportunities to reduce the energy used for freight transportation, but it will be difficult to shift large volumes from one mode to another without imposing considerable additional costs on businesses and consumers. This report explores federal government actions that could help trigger the shifts in modal shares needed to reduce energy consumption and emissions. This is one in a series of reports produced as a result of the Transportation Energy Futures project, a Department of Energy-sponsored multi-agency effort to pinpoint underexplored strategies for reducing GHGs and petroleum dependence related to transportation.

Medium Truck Duty Cycle Data from Real-World Driving Environments: Project Final Report Lascurain, M.B., Franzese, O., Capps, G., Siekmann, A., Thomas, N., LaClair, T., Barker, A., Knee, H. 11/1/2012 Reports

Oak Ridge National Laboratory, Oak Ridge, Tennessee

Since the early part of the 20th century, the US trucking industry has provided a safe and economical means of moving commodities across the country. At present, nearly 80% of US domestic freight movement involves the use of trucks. The US Department of Energy (DOE) is spearheading a number of research efforts to improve heavy vehicle fuel efficiencies. This includes research in engine technologies (including hybrid and fuel cell technologies), lightweight materials, advanced fuels, and parasitic loss reductions. In addition, DOE is developing advanced tools and models to support heavy vehicle research and is leading the 21st Century Truck Partnership and the SuperTruck development effort. Both of these efforts have the common goal of decreasing the fuel consumption of heavy vehicles. In the case of SuperTruck, a goal of improving the overall freight efficiency of a combination tractor-trailer has been established. </p><p>This Medium Truck Duty Cycle (MTDC) project is a critical element in DOE's vision for improved heavy vehicle energy efficiency; it is unique in that there is no other existing national database of characteristic duty cycles for medium trucks based on collecting data from Class 6 and 7 vehicles. It involves the collection of real-world data on medium trucks for various situational characteristics (e.g., rural/urban, freeway/arterial, congested/free-flowing, good/bad weather) and looks at the unique nature of medium trucks' drive cycles (stop-and-go delivery, power takeoff, idle time, short-radius trips). This research provides a rich source of data that can contribute to the development of new tools for FE and modeling, provide DOE a sound basis upon which to make technology investment decisions, and provide a national archive of real-world-based medium-truck operational data to support energy efficiency research. The MTDC project involved a two-part field operational test (FOT). For the Part-1 FOT, three vehicles each from two vocations (urban transit and dry-box delivery) were instrumented for the collection of one year of operational data. The Part-2 FOT involved the towing and recovery and utility vocations for a second year of data collection.
