Summary

This report presents the first outcomes evaluation of Minnesota’s Toward Zero Deaths (TZD) initiative, a multidisciplinary traffic safety program established in 2003. The TZD framework integrates Enforcement, Education, Engineering, and Emergency Medical and Trauma Services to reduce roadway fatalities and serious injuries. The study addresses the need to measure the effectiveness of regionalized traffic safety efforts, which involve state and local agencies, academia, judicial systems, and advocacy groups. The evaluation focuses on five established TZD regions in Minnesota, analyzing data from the 2011 calendar year against a baseline period of 2006–2010. The primary research question assesses whether coordinated regional partnerships and strategic interventions have led to statistically significant reductions in crash rates and injuries. The methodology employs statistical comparisons using paired t-tests to evaluate changes in fatal and serious injury crashes, fatalities, and serious injuries. The baseline data represents the annualized mean from 2006 to 2010, compared against 2011 data. Statistical significance was defined at a p-value of 0.10 or lower (90% confidence interval). The evaluation grid links regional strategic goals—specifically targeting seatbelt use, driver impairment, speeding, and distraction—to specific metrics. The report details partnership activities, including the implementation of County Road Safety Plans, enforcement grants, and community awareness campaigns, to contextualize the statistical findings. The findings indicate substantial progress in traffic safety outcomes. Since the establishment of TZD in 2003, statewide fatalities dropped by 44%, significantly deviating from pre-2003 trends that projected 713 deaths in 2011. Regionally, the Southeastern Minnesota TZD Region demonstrated significant reductions across all key metrics: a 29% reduction in fatal crashes, a 40% reduction in serious injury crashes, and a 29% reduction in traffic-related fatalities. Specific behavioral improvements included a 50% reduction in unbelted fatalities, a 42% reduction in impairment-related fatal crashes, and a 56% reduction in distraction-related fatal crashes. Similar positive trends were observed in other regions, with statistical significance confirming that these reductions were consistent and profound rather than random fluctuations. The significance of this evaluation lies in establishing a causal link between regional maturity, partnership participation, and traffic safety outcomes. The report concludes that higher levels of county participation in traffic safety grants and the completion of County Road Safety Plans are strongly associated with positive safety outcomes. While impaired and distracted driving remain persistent challenges, the data supports the efficacy of the TZD model. The authors recommend expanding outreach for grants and safety plans to further enhance regional participation. This evaluation serves as a foundational benchmark for future analyses, highlighting the importance of structured, multi-agency collaboration in achieving the goal of zero traffic deaths.

Key finding

Statewide traffic fatalities dropped 44% since 2003, and higher levels of regional participation in traffic safety grants and plans are strongly associated with positive traffic safety outcomes.
