Summary
This study investigates the factors contributing to the decline in traffic fatality rates among young people in the United States, specifically examining how U.S. performance compares to other developed nations across different age cohorts. While global road fatalities have decreased over the last four decades due to technological and regulatory improvements, the U.S. has underperformed relative to peers like Germany and the Netherlands. The research was motivated by the U.S. Department of Transportation’s “Zero Deaths” policy and a lack of prior research analyzing traffic safety trends by specific age groups. The authors sought to determine which countries and age groups achieved the most significant improvements to inform future policy emulation. The researchers analyzed traffic fatality data for six age cohorts—Children (0–14), Youngsters (15–17), Late Teens (18–20), Young Adults (21–24), Adults (25–64), and Seniors (65+)—across the U.S. and 15 other developed countries. Using data from selected years between 1990 and 2010, they compared both absolute fatality levels and rates of improvement. The analysis identified the best-performing country for each age group based on lowest fatality rates or highest improvement rates, verified through robust panel modeling. This benchmarking approach aimed to highlight successful strategies that could be replicated to support the U.S. goal of zero traffic deaths. The findings reveal significant divergence in U.S. performance relative to peer countries. In 1990, U.S. fatality rates were 2 to 2.5 times higher than the best-performing country; by 2010, this gap widened to 3.5 to 5.0 times. The most substantial disparity occurred among Children, where the U.S. fatality rate was 5.1 times higher than the UK’s in 2010, compared to 2.2 times in 1990. Conversely, Youngsters (15–17) showed the strongest relative improvement in the U.S., likely due to the adoption of Graduated Driver Licensing (GDL) programs. The UK emerged as the best performer for Children and Seniors, attributed in part to comprehensive educational initiatives like “Education Think.” Switzerland led improvements for Young Adults, while Sweden and Japan were highlighted for Youngsters and Late Teens, respectively. The study concludes that monitoring road safety performance by age cohort is essential for understanding population-level data and identifying effective interventions. The widening gap in fatality rates for Children and Seniors in the U.S. suggests an urgent need to explore causes and solutions, particularly by examining policies in high-performing countries like the UK. The authors argue that benchmarking against these successes is a crucial step toward achieving the ambitious goals of the Zero Vision initiative, emphasizing that age-specific strategies are necessary to address the varying risks and improvement trajectories across different demographic groups.
Key finding
US fatality rates for Children and Seniors were 3.5 to 5.0 times higher than the best-performing countries in 2010, whereas Youngster safety improvements closely tracked peer nations.
