We examined the efficacy of three Driving While Intoxicated (DWI) programs in New Jersey from 1980 through 1985, using covariance analysis of county data. Road blocks, the major component of the Strike Force program, were associated with a drop of 10-15 per cent in the single vehicle nighttime crash rate and showed a relatively stable effect over time. DWI Task Force, an education program, was associated with a 6-10 per cent total decline in the crash rate and declining impact over time. SOBER, another education program, was associated with a small effect in the first year and little or no effect thereafter.
我们运用县数据的协方差分析，研究了1980年至1985年新泽西州的三种酒后驾车（DWI）项目的成效。路障是打击行动项目的主要组成部分，它使单车夜间撞车率下降了10%至15%，且随着时间推移效果相对稳定。酒后驾车特别工作组是一个教育项目，它使撞车率总体下降了6%至10%，且随着时间推移影响逐渐减弱。清醒项目是另一个教育项目，它在第一年有较小影响，之后影响甚微或没有影响。
