In MOBILE5, adjustments were made to the basic exhaust emission estimates to account for the effects of area wide average trip speeds using speed correction factors developed from a number of driving cycles with varying average speeds. For MOBILE6 EPA has adjusted for differences in driving behavior versus roadway (facility) type and aggressive driving effects as well as average speed. EPA has developed new facility-specific inventory driving cycles, based on “real world” representative driving studies, and tested vehicles using these cycles to address these purposes. This report describes the analysis of the new driving cycle data and presents the resulting speed correction factors used in MOBILE6 for the gasoline passenger car and light duty gasoline truck classes.
