Highway Vehicle Particulate Emission Modeling Software - PART5

Note: MOBILE6.2 is EPA's most up-to-date model for estimating particulate emissions from highway vehicles.

In February 1995, the Office of Transportation and Air Quality (OTAQ) revised the particulate emission factor model, PART5, which was originally distributed in August 1995. This newest version of the PART5 model has been updated to correct the problems explained in the "PART5 User Information Sheets #1 and #2," as well a few other problems discovered since the initial release. The model and user guide are available below.
