Working conditions for employees who often operate on a 24/7/365 schedule are noted in TRB's Critical Issues in Transportation for 2024 and Beyond as something that management and labor must come to terms with in efforts to retain engaged, committed workers. This week, TRB released two publications that will help attain these workforce goals.
NCHRP Synthesis 637: Tracking Safety Leading Indicators to Improve DOT Employee Safety Performance, from TRB's National Cooperative Highway Research Program, explores issues related to safety leading indicator practices used by state departments of transportation to track and prevent occupational injuries and other incidents. It also includes findings from a survey related to safety leading indicators of practices used by state DOTs.
TR News (January-March 2025) includes articles on mitigating injury and death in work zones. It also has features on the business jet industry in the United States, how air service development supports regional economies, and ways to reduce the use of dry salt for winter pavement maintenance. This is Issue 352 and the last print edition before the magazine goes all digital.
Additionally, join conversations on workforce goals by registering for TRB's National Summit on the Future of the Transportation Workforce held June 2-4 in Westminster, CO.

New research has developed a comprehensive hazard-perception test using AI and virtual environments. A four-step process published in TRB's Transportation Research Record journal includes training an AI with superhuman performance, clustering reward scores, generalizing the test for scenario variability, and analyzing learning curves. The method improves upon traditional approaches, potentially reducing driving accidents by over 25% and offering applications for autonomous vehicles and other safety-critical industries.
Sage Perspectives has published an article detailing the findings.
