Inspection/maintenance cost effectiveness was modeled by having an example fleet of one million vehicle (gasoline light-duty vehicle only) participate for five years in a hypothetical I/M program starting in 1983. The design of the hypothetical I/M program was typical of programs now being implemented. Total costs were determined by adding together repair costs and inspection costs for the five year period, then subtracting fuel savings attributable to the I/M program for the five year period. Inspection and repair costs were estimated using data from currently operating and planned programs. Emission reductions were obtained using MOBILE 2 (EPA's model for predicting the emission behavior of a fleet of vehicles with and without I/M) to estimate the masses of HC and CO emissions that would be removed during the five year period by the hypothetical I/M program.
