Combined Interface for Project Level Air Quality Analysis

The U.S. Environmental Protection Agency (EPA) developed the computer program, Motor Vehicle Emissions Simulator (MOVES), to model carbon monoxide (CO), coarse particulate matter (PM10), fine particulate matter (PM2.5), and mobile source air toxics (MSATs) emissions. The model can also perform greenhouse gas emissions analyses. Forty-nine states use MOVES while California uses EMission FACtors (EMFAC) model to estimate vehicle emissions. Project level analyses may also require the use of dispersion models such as CAL3QHC, CAL3QHCR, or AERMOD. Running these dispersion and emissions models require a high level of technical expertise. With the complexity of the models, the associated requirements/guidance, and the computer programs developed, many state DOTs are finding it technically challenging to perform air quality analysis or review analyses completed by consultants. Practitioners need a combined interface to input data on a step-by-step basis, select dispersion or emission models, run the models, and process the outputs. The objective of this project is to develop a combined user-friendly interface for air quality practitioners to run: (a) EPA approved public domain emission and dispersion models for carbon monoxide and particulate matter, and (b) public domain emission models for mobile source air toxics and greenhouse gases. The interface will be applied by practitioners to conduct and review project level transportation air quality analyses.
