Abstract
The authors present estimates of air pollution costs from various types of motor vehicles in the Los Angeles region. The costs are dominated by mortality from particulate matter, including that formed from gaseous emissions through secondary reactions. The best estimate for the air pollution cost of the average car on the road in California in 1992 is $0.03 per mile, falling to half that amount in the year 2000. A typical heavy-duty diesel vehicle is much more costly. The cost estimates are sensitive to the assumed value of life, to the measured health effects of particulates, and to assumptions about road dust. (Author/publisher).
