Transportation Sector Demand Module of the National Energy Modeling System: Model Documentation

The Transportation Sector Demand Module of the National Energy Modeling System (NEMS) is a computer-based energy demand model of the U.S. transportation sector. The NEMS Transportation Sector Demand Module encompasses a series of semi-independent submodules and components that address different aspects of the transportation sector. The primary purpose of the comprehensive module is to provide projections of transportation energy demand by fuel type, including motor gasoline, distillate, jet fuel, and alternative fuels such as ethanol and compressed and liquefied natural gas (CNG/LNG). The module also projects selected intermediate values necessary to determine energy consumption. These elements include estimates of passenger travel demand by light-duty vehicles, air, and mass transit; estimates of the energy requirements to meet this demand; projections of vehicle stock and the penetration of new technologies; and estimates of the demand for truck, rail, marine, and air freight transport that are linked to projections of industrial output, international trade, and energy supply. The NEMS Transportation SectorDemand Module consists of four submodules representing a variety of travel modes that are different in design and utilization but share the same ultimate purpose: to convey passengers and freight. The four submodules include: Light-Duty Vehicle (LDV), Air Travel, Freight Transport (heavy truck, rail, and marine), and Miscellaneous Energy Demand.
