Cost-effectiveness of Automobile Inspection/maintenace Programs

The study presents conclusions in two areas:

Cost-effectiveness: The cost of emission reduction ranges from $580 to $2,048 per ton for hydrocarbons and from $30 to $203 per ton for carbon monoxide. The choice of a figure within this range depends on assumptions concerning the value of owner time, incremental maintenance and repair costs, the prior existence of a safety inspection program, and the control technology used on the automobile. Most importantly, the choice depends on the methodology used to calculate the cost-effectiveness ratio.

Fuel economy: Estimates of inspection/maintenance benefits for 1980 and earlier automobiles range from zero to four percent for failed vehicles. For 1981 and later model years, estimates run as high as a 15 percent gain when a failed vehicle is repaired. Fuel economy is a key factor in inspection/maintenance cost-effectiveness; even a very small percentage gain can more than make up for all other inspection/maintenance program costs.
