Texas-Specific Drive Cycles and Idle Emissions Rates for Using with EPA's MOVES Model : Final Report

The U.S. Environmental Protection Agency's (EPA) newest emissions model, MOtor Vehicle Emission Simulator (MOVES), uses a disaggregate approach that enables the users of the model to create and use local drive schedules (drive cycles) in order to perform an accurate analysis. However, only the national average drive schedules are currently included in the default database of the model. Furthermore, the cold start and idling emissions and activity data of heavy duty diesel trucks (HDDVs) that are included in the MOVES model are based on a very limited number of data sources even though they are very important components of the total on-road mobile source emissions inventory. This report provides local drive cycles emissions rates for heavy-duty diesel trucks. The report also compares estimated emissions from MOVES for a sample of vehicles to real-world in-use emissions measurements. Furthermore, the technical and tactical issues of integrating the results of this study into MOVES for formal emissions analyses purpose are investigated and recommendations provided based on the findings.
