A Unified Framework for Roadway Safety

A Unified Framework for Roadway Safety

How can transportation professionals determine which safety strategies to prioritize? The Unified Framework for Safe System Implementation brings decades of safety research together to help agencies make more informed decisions. By connecting exposure, severity, and crash likelihood to different roadway contexts, the framework offers a practical way to prioritize strategies across planning, policy, design, and operations.

Meeting the Deadline Isn’t the Same as Solving the Problem

Meeting the Deadline Isn’t the Same as Solving the Problem

New state requirements are changing how cities approach truck route planning, but meeting a deadline doesn’t necessarily resolve conflicts between freight movement and neighborhood needs. See how Jurupa Valley used truck data, community input, and clear evaluation criteria to rethink its truck network, meet California’s AB 98 requirements, and reduce truck traffic exposure in sensitive areas.

Understanding AI’s Role in Transportation Safety

Understanding AI’s Role in Transportation Safety

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.

New NCHRP Toolkit Helps Agencies Build Safety Into Everyday Decisions

New NCHRP Toolkit Helps Agencies Build Safety Into Everyday 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.

Announcing Safety Multipliers

Announcing Safety Multipliers

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.

The City That Knows How to Say Yes

The City That Knows How to Say Yes

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.
