Objective: Develop methods to characterize and mitigate harmful effects of non-exhaust (tire wear, brake wear, re-entrained road dust) motor vehicle pollutant emissions to water quality, air pollution, and environmental and…
Comparisons of alternative build and no-build scenarios in project-level air quality analyses for NEPA and conformity typically focus on comparisons of emissions and/or ambient concentrations of specific pollutants, including greenhouse…
EPA suggested in response to a comment in the last MOVES Model Review Workgroup that grade-specific drive cycle data (second-by-second speeds) be used instead of model default data (which generally…
The objective for this study would be to compile information on the state of the practice among state DOTs for using microscopic traffic simulation in support of project-level air quality…
State Departments of Transportation (DOTs) conduct project-level air quality analyses for the National Environmental Protection Act (NEPA) and to meet the requirements of the Environmental Protection Agency’s (EPA) transportation conformity…
Comparisons of alternative build and no-build scenarios in project-level air quality analyses for NEPA and conformity typically focus on comparisons of emissions and/or ambient concentrations of pollutants, namely greenhouse gases…
As the U.S. Environmental Protection Agency (EPA)’s preferred air dispersion model for refined transportation project analyses, AERMOD is used to model roadway “link” source using AREA, VOLUME, LINE, RLINE, or…
Emission factors versus speed curves generated using the MOVES3 model exhibit very anomalous behavior at higher road grades that are within the range encountered in project-level air quality analyses for…
Regulatory requirements for conducting quantitative project-level analyses for particulate matter (PM) were introduced by EPA with the release of the MOVES model in 2010. This proposed study would prepare a…
The recently completed NCHRP study (20-05 Topic 51-18 Practices for Project-Level Analyses for Air Quality) included a recommendation for the development of a template guidance document for the preparation of…
