According to a new study by professors Michael Morrisey of the University of Alabama- Birmingham and David Grabowski of Harvard Medical School, the rate of traffic fatalities in the U.S. falls as gas prices rise.

The study of traffic statistics and gas prices during the period ranging from 1985 to 2006 theorized that as fuel costs rise, more people drive slowly in order to converse fuel consumption and choose not to drive unless it is necessary, resulting in fewer drivers on American roadways and fewer motor vehicle accidents. Morrisey and Grabowski's data analysis found that for each 10% increase in average U.S. gas prices, the number of traffic fatalities among all drivers fell by 2.5% and the number of auto accident deaths among drives aged 15-17 fell by 6%.

Morrisey also noted that as fuel costs are now over 60% higher on average than in 2006, the most expensive year covered by the study, he expects that the number of deaths resulting from auto accidents may fall by as much as 1000 per month from 2006 numbers.

Morrisey and Grabowski's study was presented at a meeting of the American Society of Health Economists in Raleigh-Durham, N.C. Automobile accidents in the United States result in over 40,000 deaths annually.
