Abstract
Three methodological techniques are used to explore the impact of DWI (driving while impaired) programming in the State of New Jersey. The programs consisted of a community-wide Task Force whose membership was drawn from local police agencies, alcohol treatment facilities, and public schools, an intensified public education and information campaign, and the use of roadside sobriety checkpoints. The first technique used cross-sectional data from 21 counties to examine fatalities and accidents. The second technique used pooled cross-sectional county data in a covariance model to examine program effects over time. The third technique relied upon intervention analysis, a form of time series, to ascertain the effects of the programs in one county.
