Regional emissions analysis requirements are applicable for all nonattainment and maintenance areas in making a conformity determination. The regional emissions analysis forms the basis of the conformity determination and is performed to demonstrate the consistency of transportation plans and TIPs with the SIP motor vehicle emissions budgets.
- MOVES2010a Regional Level Sensitivity Analysis (December 2012) - Prepared by Volpe National Transportation Systems Center for FHWA, this document discusses the sensitivity of various input parameter effects on emission rates using MOVES2010a at the regional level. Pollutants included in the study are CO, NOx, PM2.5, and VOCs.
- Improving Vehicle Fleet, Activity, and Emissions Data for On-Road Mobile Sources Emissions Inventories (September 2011). Prepared by the University of California at Riverside for FHWA, this report investigates several modeling concepts and methodologies in the MOVES emissions model and explores new data sources and new methods for utilizing existing data sources to improve the emission inventory and analysis of on-road mobile sources.
- Advances in Project Level Analyses or (PDF , 244KB) (November 2010) - Prepared by E.H. Pechan & Associates for FHWA, this report provides research results and methods for preparing project-level emissions analyses that take advantage of the capabilities of the MOVES emissions model.
- Modifying Link-Level Emissions Modeling Procedures for Applications within the MOVES Framework (September 2010) - Prepared by Eastern Research Group, Inc. for FHWA, the primary goal of the study was to ease the transition to the MOVES model by providing both a road map for developing updated emissions inventories, as well as an analysis of the likely impacts of the transition on the emissions inventories themselves.
- Multi-Pollutant Emissions Benefits of Transportation Strategies (or PDF, 1.3 MB) (November 2006) - Prepared by ICF Consulting for FHWA, this report provides a compendium of traditional and innovative transportation-related control strategies. It identifies the emissions effects of the strategies on CO, PM10, PM2.5, NOx, VOCs, SOx, and NH3.
- MOBILE6 Implementation Experience (June 2005) - FHWA, in conjunction with the Association of Metropolitan Planning Organizations (AMPO) Air Quality Subcommittee, worked with a group of MPOs to document their experience in applying MOBILE6 in the conformity process. Thus purpose of the study is to provide an understanding of what steps these organizations took to prepare for use of the new MOBILE model and to identify potential training and technical assistance needs. Specifically, this study documents how MPOs are implementing MOBILE6, what data are being collected locally, and how data are being collected and identifies implementation issues that arose during the transition to MOBILE6.
- Emissions Benefits of Land Use Planning Strategies (or PDF, 3.1 MB) (December 2004) - Prepared by the Louis Berger Group for FHWA, this report documents what land use planning strategies are being considered for reduction of on-road mobile source emissions and how these strategies are being incorporated into various planning activities. It also documents the magnitude of the emissions benefits that were estimated and any consideration of relative cost-benefit analysis of the strategies. The report also examined the methodologies being used to measure the impacts of changes in terms of on-road moblie source emissions attributable to land use strategies and the additional research needs related to emissions benefits of land use strategies.
- Regional Emissions Analysis in Small Urban and Rural Areas (or PDF, 405 KB) (October 2004) - Prepared by ICF Consulting for FHWA, this report documents and assesses methodologies that can be used for estimating regional emissions for conformity analyses in small urban or rural areas. The report provides transportation practitioners a menu of methodologies and techniques for small urban or rural areas to consider for regional emissions analysis. The report also includes an assessment of these methodologies/techniques and highlights strengths and weaknesses of each.
- Implications of the Implementation of the MOBILE6 Emissions Factor Model on Project-Level Impact Analyses Using the CAL3QHC Dispersion Model (or PDF, 1.9 MB) (August 2004) - Prepared by ICF Consulting for FHWA, this report discusses how revisions to the MOBILE model affect the estimation of localized CO concentrations, including problems and difficulties in the interaction of MOBILE6 with CAL3QHC, as well as recommendations for addressing these issues. In addition, this report discusses how the implementation of MOBILE6 impacts screening assessment procedures.
- Transportation/Air Quality Issues in Rural Areas (April 2003) - Prepared by the Dye Management Group for FHWA, the purpose of this study was to increase understanding of how many rural areas are facing air quality issues and to identify the main causes for their exceeding air quality standards. The study focuses on transportation's contribution to the air quality problems in rural areas and how these areas are meeting certain Clean Air Act requirements related to motor vehicle emission sources.
