The Emission Control Technology Division (ECTD) of EPA has generated heavy-duty transient engine and chassis cycles representative of the truck operational data collected during the CAPE-21 survey. This report summarizes the considerations and decision process used in arriving at the final vehicle categories for which heavy-duty transient cycles were developed. Statistical comparisons between various operational parameters were primarily relied upon in selecting the valid category combinations. It was possible to reduce the original number of vehicle categories from 28 to 9 for engine cycles and from 28 to 5 for chassis cycles.
