The Fairfax Alcohol Safety Action Project (ASAP) was begun in 1971 as one of 35 federally-funded demonstration projects, designed to implement and evaluate a comprehensive community alcohol countermeasures program. The Fairfax ASAP was approved for three years and funded with $2.1 million in an attempt to confront and aemliorate the community's drunk driving problem. In order to measure the impact of the Fairfax ASAP on fatal, injury, and property damage crashes after two full years of project operations, crash data from the ASAP years (1972, 1973, and 1974) were compared with data from pre-ASAP years. In addition, actual crash data were compared with the predictions that were developed through analysis of statistical trends and projections. During the years of ASAP operations, as shown by these data, fatal crashes and fatalities have been steadily reduced. The total number of accident fatalities has decreased from 100 in 1971 to 85 in 1972, to 78 in 1973, and to 62 in 1974. In addition, the data show a significant difference in the projected injury crashes and the actual injury crashes. The actual number was reduced from 1973, and is well below the projected number of injury crashes. In four categories of measurement--fatal crashes, fatalities, injury craches, property damage crashes--three were held below projections during the three year period of ASAP operations. This may be compared to a similar area in Virginia which was used as a control. No ASAP has been in operation. In the same three year period, none of the four measures showed a significant reduction below the projected figures, thus indicating the favorable impact of the ASAP program in the Fairfax area. Comparative data for fatal, personal injury, and property damage accidents are presented in Table A-1. Further evidence of the effectiveness of the ASAP program can be found in the results of a series of special roadside surveys designed to measure the extent of the drinker/drivers' threat to highway safety. The first night-time survey, conducted before ASAP countermeasures were fully operational, revealed that, on the average, the number of drivers passing a road checkpoint who were legally intoxicated was 4.2% of the driving population, on a random basis. The third survey, completed in the fall of 1973, indicated that at that time only 2.7% of the drivers in the sample were legally drunk, a decrease of 35%. The fourth survey, completed in the fall of 1974, indicated that at that time 4.5% of the drivers in the sample were legally drunk. (The 1971 figures were weighted to the 0.10% BAC level; thus, the 4.2% figure was not calculated at the old 0.15% level.)
