Description:
This research outlines a proposed Heavy-Duty Diesel Vehicle Modal Emission Modeling Framework (HDDV-MEMF) for heavy-duty diesel-powered trucks and buses. The heavy-duty vehicle modal modules being developed under this research effort, although different, should be compatible with the structure within MOVES. In the proposed HDDV-MEMF, emissions from heavy-duty vehicles are predicted as a function of hours of on-road operation at specific engine horsepower loads. Hence, the basic algorithms and matrix calculations in the heavy-duty diesel vehicle modeling framework should be transferable to MOVES. The specific implementation approach employed by the research team to test the model in Atlanta is somewhat different, in that an existing GIS-based modeling tool is being adapted to the task. The new model implementation is similar in general structure to the previous modal emission rate model known as the Mobile Assessment System for Urban and Regional Evaluation (MEASURE) model.
Sponsored by the U.S. EPA, this exploratory framework is designed to be applied to a variety of policy assessments. The model can be used to evaluate policies aimed at reducing the emission rates from heavy-duty vehicles as well as policies designed to change the on-road operating characteristics to reduce emissions.
