Available in PDF, EPUB and Kindle. Book excerpt: This report documents the objectives, analytical approach and development of the National Energy Modeling System (NEMS) Transportation Model (TRAN). The report catalogues and describes the model assumptions, computational methodology, parameter estimation techniques, model source code, and forecast results generated by the model. The NEMS Transportation Model comprises a series of semi-independent models which address different aspects of the transportation sector. The primary purpose of this model is to provide mid-term forecasts of transportation energy demand by fuel type including, but not limited to, motor gasoline, distillate, jet fuel, and alternative fuels (such as CNG) not commonly associated with transportation. The current NEMS forecast horizon extends to the year 2010 and uses 1990 as the base year. Forecasts are generated through the separate consideration of energy consumption within the various modes of transport, including: private and fleet light-duty vehicles; aircraft; marine, rail, and truck freight; and various modes with minor overall impacts, such as mass transit and recreational boating. This approach is useful in assessing the impacts of policy initiatives, legislative mandates which affect individual modes of travel, and technological developments. The model also provides forecasts of selected intermediate values which are generated in order to determine energy consumption. These elements include estimates of passenger travel demand by automobile, air, or mass transit; estimates of the efficiency with which that demand is met; projections of vehicle stocks and the penetration of new technologies; and estimates of the demand for freight transport which are linked to forecasts of industrial output. Following the estimation of energy demand, TRAN produces forecasts of vehicular emissions of the following pollutants by source: oxides of sulfur, oxides of nitrogen, total carbon, carbon dioxide, carbon monoxide, and volatile organic compounds.

Available in PDF, EPUB and Kindle. Book excerpt: The attachments contained within this appendix provide additional details about the model development and estimation process which do not easily lend themselves to incorporation in the main body of the model documentation report. The information provided in these attachments is not integral to the understanding of the model's operation, but provides the reader with opportunity to gain a deeper understanding of some of the model's underlying assumptions. There will be a slight degree of replication of materials found elsewhere in the documentation, made unavoidable by the dictates of internal consistency. Each attachment is associated with a specific component of the transportation model; the presentation follows the same sequence of modules employed in Volume 1. The following attachments are contained in Appendix F: Fuel Economy Model (FEM)--provides a discussion of the FEM vehicle demand and performance by size class models; Alternative Fuel Vehicle (AFV) Model--describes data input sources and extrapolation methodologies; Light-Duty Vehicle (LDV) Stock Model--discusses the fuel economy gap estimation methodology; Light Duty Vehicle Fleet Model--presents the data development for business, utility, and government fleet vehicles; Light Commercial Truck Model--describes the stratification methodology and data sources employed in estimating the stock and performance of LCT's; Air Travel Demand Model--presents the derivation of the demographic index, used to modify estimates of personal travel demand; and Airborne Emissions Model--describes the derivation of emissions factors used to associate transportation measures to levels of airborne emissions of several pollutants.

Available in PDF, EPUB and Kindle. Book excerpt: Texas National Energy Modeling Project: An Experience in Large-Scale Model Transfer and Evaluation reports on the Texas National Energy Model Project (TNEMP) experience. The TNEP was tasked with providing an independent evaluation of the Energy Information Administration's (EIA) Midterm Energy Forecasting System. It also provided recommendations to the Texas Energy Advisory Council concerning the maintenance of a national modeling system by the Council to evaluate Texas impacts within a consistent national modeling framework. The book provides all of the summary material documenting the entire experience, sequentially, from beginning to end. It first lays out the purposes of TNEMP, the organizational structure for the study, and an explanation of the evaluation criteria used to guide the model critiques. It summarizes in some detail the important findings of each of the 11 studies contained in Part II published under a separate cover. It presents the National Advisory Board's assessment of the integrity of the evaluation project, their views of important outcomes of the TNEMP experience, and important recommendations to TNEMP and EIA. The final chapters contain an overview reply by EIA and a summary of a workshop held at the end of the project to discuss substantive issues raised by TNEMP.
