United States Environmental Protection Agency Dispersion Model Source Type and Options

Project Information

Project ID:
FHWA-PROJ-20-0052
Project Abstract:

The objective of this Environmental Protection Agency and Federal Highway Administration Interagency Agreement is support research to assess whether the current dispersion models can be improved for predicting near road air quality and identify appropriate enhancements. The assessment of the various features and input specifications will ultimately promote any beneficial modifications to advance the state of the science in near road dispersion modeling. Specifically, the research activity will be used to address the following goals:

  • First, advance the capability of the beta RLINE source type to make consistent with the requirements for inclusion as a regulatory model by additional evaluation of the URBAN option when used with RLINE through the conduct of source configuration testing, among others to advance the URBAN as a beta option for RLINE.
  •  Second, through research into the implications of barriers to improve near road air quality analysis.

Project Outputs:

Incorporate the changes necessary to make sure RLINE source type when used with the URBAN option meets the requirement to be eligible as a regulatory default option in a future version of AERMOD.

Model each of the 3 SF6 tracer experiments in AERMOD including No barrier case, One barrier case and Two barrier case.

Project Outcomes/Impact:

The assessment of the various features and input specifications will ultimately promote any beneficial modifications to advance the state of the science in near road dispersion modeling.
