A BEHAVIORAL ANALYSIS OF EPA'S MOBILE EMISSION FACTOR MODEL
This paper examines the behavioral and stochastic aspects of modeling emission reductions from vehicle inspection and maintenance (I/M) programs. Forecasts of emission reductions from such programs have been modeled by the use of the Environmental Protection Agency's MOBILE Model, the EPA's computer model for estimating emission factors for mobile sources. The paper examines the structure of this model and reviews the way behavior of drivers, mechanics and state regulatory authorities is incorporated in the current generation of the model. Particular focus is aimed on assumptions about vehicle repair under I/M, compliance with I/M requirements, and the impact of test measurement error on predicted I/M effectiveness. Also included are some preliminary comparisons of the model's outcomes to results of the I/M program in place in Arizona. Finally, some sensitivity analyses are performed to determine the most influential underlying parameters of the model.
