  • Emission Reduction Policy Evaluation

Researchers perform evaluations for Georgia’s Enhanced Vehicle Inspection and Maintenance (I/M) Program as well as analyze the air quality benefits derived from this and other emission reduction programs. The unique efficiency evaluation methodology developed by the group includes statistical analysis of multi-year accumulated on-road remote sensing data, evaluation of potential air quality impacts associated with current Environmental Protection Agency (EPA) policies, statistical modeling of utilization rates of different types of I/M stations, comparison of on-road emission measurements with existing EPA software models such as the Mobile Source Emission Factor Model (MOBIL6) and Motor Vehicle Emission Simulator (MOVES).
