Medium Truck Duty Cycle Data from Real-World Driving Environments: Project Final Report

The U.S. Department of Energy (DOE) is spearheading a number of research efforts to improve heavy vehicle fuel efficiencies (FEs). 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 (21CTP) and the SuperTruck development effort. 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. This Medium Truck Duty Cycle (MTDC) Project is a critical element in DOE’s vision for improved heavy vehicle energy efficiency. It involves the collection of real-world data 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 [PTO], idle time, short-radius trips) to provide a rich source of data that can contribute to the development of new tools, to provide DOE a sound basis upon which to make technology investment decisions, and to provide a national archive of real-world-based medium-truck operational data to support vehicle energy efficiency research.
