A 'Compilation of Air Pollutant Emission Factors' (AP-42) reports data on atmospheric pollutants for which sufficient data exist to establish realistic emission estimates. The highway mobile source emission factors presented in this Supplement to the 4th edition of AP-42 (EPA, Sept. 1985) are based on EPA's MOBILE4 emission factor model (EPA, 1989), and provide emission factors for eight vehicle types and the highway vehicle fleet as a whole for a variety of different conditions (e.g., calendar year, average speed, temperature, fuel volatility, and operating modes). The supplement also discusses the algorithms used in MOBILE4 to estimate such emission factors.
