“Eyes on the Street”: The Impact of Tennessee's Emergency Cellular Telephone Program on Alcohol-Related Fatal Crashes

Abstract

Using longitudinal data drawn from Tennessee's Fatality Analysis Reporting System (FARS) and a multiple time-series research design, the authors assessed whether an emergency cellular telephone program, established on April 1, 1995, reduced alcohol-related fatal crashes. Maximum-likelihood results revealed a 2.5 percent decline in the alcohol-related fatal crash rate on roads serviced by the program. No significant change in the monthly percentage of fatal crashes attributed to drunk drivers was observed on roads where the program was not implemented. Emergency cellular telephone programs show promise as an effective and relatively inexpensive means for improving highway safety.
