ALCOHOL SAFETY ACTION PROJECT--CITY OF PHEONIX. ANNUAL REPORT 1975. SECTION II. AN ANALYSIS OF TOTAL PROJECT IMPACT
The Project is comprised of a series of integrated countermeasures directed toward the apprehension and rehabilitation of problem drinkers who drive. Major activities during 1975 included: increased DWI enforcement; adjudication of DWI offenders through a quasi- diversionary program; a variety of rehabilitation options, with referrals based on severity of clients' drinking problem; legislative and regulatory activities in support of desirable alcohol-related legislation; a public information and education effort; Project evaluation by an in-house research unit; and Project administration carried out directly under the City Manager's office. The report describes these activities in detail, and charts the ASAP system process from arrest through final disposition of the DWI case. Nine tables of key countermeasure performance data are also included. The principal focus of this analytic study is on analysis of motor vehicle crashes as the ultimate performance measure by which Project impact can be determined. Results indicated a decreasing trend in both injury and total crashes during the Project's operational period. Fatal crashes appeared to be relatively unchanged; however, their characteristically low monthly frequency renders this impact measure relatively insensitive to the effects of traffic safety interventions. While it cannot, therefore, be concluded that the Phoenix ASAP has achieved its crash reduction objectives, it is nonetheless encouraging that in every case in which crash trends differed between baseline and operational periods, the change was in the direction predicted by the hypothesis of Project impact. Blood Alcohol Concentration (BAC) distributions of fatally injured drivers are also examined, comparing baseline and operational periods as a proxy measure indicative of indirect Project impact. Results failed to demonstrate a reduction in BAC readings, indicating that ASAP intervention did not have a positive effect. Finally, profiles of fatal accident incidents, drivers and pedestrians are presented for crashes taking place during the Project's operational period. Differences between alcohol-related (A/R) and other crashes are also examined. A/R drivers were more likely to be male, non-Caucasian, between 20 and 29 years of age and in the laborer occupational category. Differences with the "sober driver" profile were statistically significant and generally confirm expectations based on previous national research.
