State departments of transportation (DOTs) conduct project-level air quality analyses to comply with the National Environmental Policy Act and meet transportation conformity rule requirements where applicable. DOTs are interested in a rigorous and systematic model review and update process for regulatory dispersion models to ensure the models generate credible results.
NCHRP Research Report 1058: Assessing Air Pollution Dispersion Models for Emissions Regulation, from TRB's National Cooperative Highway Research Program, presents state-of-the-art methods and analytical approaches for project-level air quality modeling by reviewing eight air quality models in use for transportation project analyses.
Supplemental to the report are Appendix A, Appendix B, Appendix C, Appendix D, Appendix E part 1a, Appendix E part 1b, Appendix E part 1c, Appendix E part 2, Appendix F, Appendix G, and a PowerPoint presentation of the research results.
