AI is giving transportation safety practitioners new ways to analyze data, detect near misses, and respond to risk before crashes happen. Real-world examples from Bellevue, WA and San Bernardino, CA show where AI-supported technology is delivering value—and where human judgment remains essential for turning data into responsible safety decisions.
Making streets safer takes more than individual projects. Our new Safe System approach toolkit, developed through NCHRP Research Report 1181, helps agencies integrate safety into policies, budgets, design standards, and land use decisions. Explore practical tools, real-world case studies, and new IIHS Safe System success stories that show how agencies are turning safety into standard practice.
What do San Francisco’s Van Ness BRT, New York’s congestion pricing, and Arlington’s intersection program have in common? Each pulls all three Safe System levers at once. We call that pattern a safety multiplier.
What does it take for a city to say “yes” without giving up control? This perspective argues for a conditional, public-minded yes, one grounded in clear standards, evidence, and measurable outcomes, with AVs as one example of a much broader governance challenge.
