MOBILE2 is a computer program that calculates emission factors for hydrocarbons, carbon monoxide, and oxides of nitrogen for highway motor vehicles. The program uses the calculation procedures described in the Compilation of Air Pollution Emission Factors: Highway Mobile Sources, (EPA 460/3-81-005, PB 81-238305), to calculate emission factors for eight individual vehicle types in three regions of the country. These emission estimates depend upon various conditions, such as ambient temperature and vehicle usage. MOBILE2 can estimate emission factors for any calendar year between 1970 and 2020. Various groups have tried to characterize the accuracy of the MOBILE2 emission factors model by comparing its emissions results to air quality measurements during the 1970-1980 period. This report shows that such comparisons are sensitive to the input assumptions used to generate the emission results.
