Major Transport Safety Study Reveals Diverging Trends Across Americas
A comprehensive analysis of transport safety performance across 35 countries has revealed both significant progress and concerning regressions in key safety indicators, according to reports published in Scientific Reports. The study employed a hybrid machine learning-enhanced multi-criteria decision-making model to evaluate countries’ performance across multiple safety parameters between 2010 and 2020.

Sources indicate that the research methodology demonstrated high reliability through V-measure coefficients, confirming the robustness of k-means clustering with graph-based techniques for transport safety assessment. The findings provide policymakers with unprecedented insights into the complex dynamics of transport safety performance across the hemisphere.
Top Performers and Notable Declines
According to the analysis, Antigua and Barbuda (AG), Barbados (BB), and Saint Vincent and the Grenadines (VC) achieved the highest overall safety scores among the nations studied. Analysts suggest these countries excelled due to strong performance across multiple indicators, including alcohol-related traffic deaths, seat belt usage, helmet compliance, and road network density.
The report states that Uruguay (UY), Argentina (AR), and Belize (BZ) also showed significant advancements in transportation safety. However, several countries experienced notable regressions, with Saint Kitts and Nevis (KN), Jamaica (JM), Saint Lucia (LC), and Grenada (GD) displaying the most significant declines in overall achievement scores.
Critical Safety Indicators Show Mixed Results
The study evaluated numerous Safety Performance Indicators (SPIs) categorized across five dimensions: fatalities (A), road user behavior (B), infrastructure (C), socioeconomic factors (D), and policy enforcement (E). The findings reveal a complex picture of progress and challenges across these domains.
Analysts suggest that behavioral indicators showed particularly concerning trends. Seatbelt usage in both front and rear seats, along with helmet compliance, displayed regressive patterns in multiple countries. Peru (PE) experienced significant declines in rear seatbelt usage, while Saint Vincent and the Grenadines (VC) saw deterioration in front seatbelt compliance.
Infrastructure indicators presented a more positive outlook, with twenty-eight nations reporting improvements in road paving percentages. The Bahamas (BS), Antigua and Barbuda (AG), Uruguay (UY), and Barbados (BB) showed the most notable progress in this critical area of benchmarking transportation infrastructure quality.
Socioeconomic Factors and Enforcement Drive Improvement
The report indicates that socioeconomic indicators, particularly urban population growth and GDP per capita, improved in 29 states, with The Bahamas (BS) and Antigua and Barbuda (AG) experiencing the most significant growth. These factors are crucial as they influence governments’ ability to allocate resources for transport safety infrastructure, reflecting broader economic developments that can impact public safety investments.
Policy enforcement emerged as another area of substantial progress, with twenty-seven states reporting improvements across speed limit laws, drunk driving laws, seat belt laws, and helmet use laws. The most significant enhancements were observed in Antigua and Barbuda (AG), Uruguay (UY), and The Bahamas (BS), suggesting that strengthened legal frameworks are contributing to safety improvements.
Regional Grouping Reveals Diverse Strengths and Weaknesses
The study employed geographical grouping to facilitate peer learning and targeted improvement strategies. According to the analysis, top-ranking countries within each group did not necessarily outperform others across all indicators, highlighting unique national strengths and improvement opportunities.
In Group 1, Grenada showed particular strength in specific fatality indicators, while Barbados excelled in infrastructure metrics. The findings demonstrate how diverse factors can influence safety outcomes across different national contexts.

Group 2 analysis revealed that Canada and the United States exhibited high scores in behavioral and policy-related indicators, suggesting strong institutional frameworks. Meanwhile, countries in Group 3 displayed varied performance, with the Dominican Republic standing out in certain fatality indicators and Uruguay performing well in enforcement factors.
Implications for Policy and Future Safety Improvements
The comprehensive assessment provides invaluable insights for transportation authorities and policymakers seeking to reduce traffic fatalities and injuries. According to researchers, the findings highlight the urgent need for countries to strengthen transport safety measures, expand road network density, and address behavioral factors contributing to road accidents.
Analysts suggest that the benchmarking approach enables countries to identify specific areas for improvement and learn from peers facing similar challenges. This is particularly relevant given the political and economic transformations occurring across the region that may impact transportation safety priorities and resource allocation.
The report emphasizes that even high-performing countries have opportunities for improvement through shared learning. The findings underscore the importance of continuous monitoring and adaptation of transport safety strategies, with the methodology providing a robust framework for ongoing assessment similar to standards used in scientific evaluation across multiple disciplines.
As transportation systems continue to evolve with new technologies and changing patterns, this research provides a critical baseline for measuring progress and guiding interventions. The recognition of such achievement in safety performance, while not equivalent to military honors like the Victoria Cross, represents significant progress in protecting citizens and creating safer transportation networks across the Americas.
