AN EVALUATION OF THE DEPARTMENT OF TRANSPORTATION'S ALCOHOL SAFETY ACTION PROGRAM

An evaluaton of 35 Alcohol Safety Action Projects (ASAPs) was conducted by the Department of Transportation, National Highway Traffic Safety Administration, between 1971 and 1976. Nighttime (8 p.m. to 8 a.m.) fatal crashes were used as the criterion measure in lieu of alcohol-related crashes; roadside surveys of the blood alcohol content (BAC) of drivers were used as an intermediate measure of project impact. A time series analysis was used to evaluate changes in the nighttime fatal crash levels of the ASAPs and of 11 comparison sites. Of the 35 ASAPs examined, 12 sites had significant crash reductions during their demonstration period. The reductions associated with the ASAP program varied from 15% to 66% of the baseline nighttime fatal crash level. In none of the comparison sites associated with these 12 ASAPs was there a significant reduction in nighttime fatal crashes. Eight of the 12 ASAP sites with significant reduction in nighttime fatal crashes also conducted roadside surveys of drivers' BAC levels. As a group, these 8 showed a significant reduction in the proportion of drivers with illegal BAC levels (is greater than or equal to 10%). Eleven of the 23 ASAP sites that did not have a significant reduction in nighttime fatal crashes also conducted surveys. As a group these 11 did not show a significant reduction in the proportion of drivers with illegal BACs (is greater than or equal to 0.10%). /Author/
