• Abstract:
  This report is one of a group of research reports sponsored by the Federal Highway Administration (FHWA) through State Departments of Transportation (DOTs) in a partnership to test two new source types within the AERMOD modeling regime (Version 21112): RLINE and RLINEXT. The Environmental Protection Agency (EPA) published a final rule revising the agency's Guideline on Air Quality Models (Appendix W to 40 CFR Part 51) which made AERMOD the preferred model for refined transportation project analyses beginning in January 2020. New algorithms within AERMOD are intended for this purpose. These include RLINE (Research Line) and RLINEXT (Research Line Extended) and were developed through efforts of the EPA's Office of Research and Development (ORD). RLINEXT includes the ability to model noise barriers along the roadway as well as depressed sections.
