SOUTH DAKOTA: ASAP ANALYTIC STUDY NO. 1 - 1976. AN ANALYSIS OF TOTAL PROJECT IMPACT

The study assesses the contribution of the South Dakota Alcohol Safety Action Project to highway safety by meeting its ultimate objective of reducing the frequency of alcohol related fatal and injury crashes. Selected accident subsets that are more commonly alcohol involved were used as proxy measures for alcohol related crashes. Significant declines in both drift and level were found in total, nighttime and weekend injury crashes. The corresponding fatal crash subsets were not sensitive measures due to small monthly frequencies, however all of these series exhibited slight negative drifts over the operational period. The BAC distributions of drivers involved in fatal crashes, drivers arrested for DWI, or drivers stopped in roadside surveys provided little evidence of a decline in the frequency of alcohol impaired driving.
