Evaluation of Innovative State and Community Alcohol Projects: Breath Alcohol Testing Program Effectiveness, Impact and Transferability

摘要

Breath Alcohol Testing (BAT) programs in Albuquerque and Santa Fe, New Mexico are evaluated in regard to effectiveness, impact, and transferability of the special DWI enforcement squads and their use of BAT Mobiles. Squad activity effectiveness is measured with DWI arrests. Univariate time series analysis verifies that department DWI arrests generally double. Crashes are analyzed for impacts resulting from the BAT programs. Multiple time series analysis applied to Wednesday through Saturday Night (7:00 p.m. - 5:00 a.m.) Fatal and Injury (WSNFI) crashes, their complements and comparison series, crashes per travel exposure measured by fuel sales, show many impact forms. Albuquerque WSNFI abruptly fell 21 percent three months into BAT programs operations and gradually approach a 69 percent reduction or greater if the overall 1 percent per month trend continues. The repeat of the BAT program effectiveness and impact in Santa Fe implies concept transferability.
