The Future of Roadway Safety
Transitioning from Reactive Planning to a Fast Loop
A practical framework for modernizing the THSP with real-time, behavior-based data.
The transition to the Triennial Highway Safety Plan (THSP) requires a fundamental shift in how State Highway Safety Offices operate. Developing an effective THSP depends on accurate and timely problem identification—but today’s planning processes rely on fragmented systems and delayed data.
This report explains how SHSOs can move from a reactive “Slow Loop” to a proactive “Fast Loop” using Telematics Risk Analysis (TRA).

WHAT'S INSIDE
Eight Guiding Principles for Integrating TRA into the THSP
An actionable blueprint for identifying problems, selecting countermeasures, allocating funds, and evaluating impact — with real-world examples from state agencies.
Telematics Risk Analysis (TRA) is the key to making this shift possible. TRA uses physics and AI-based tools to measure patterns of risk on the road. Unlike traditional traffic safety data systems that rely on historical trends, TRA analyzes roadway behaviors, such as phone handling, speeding, hard braking, and aggressive cornering as they are happening. This anonymized, aggregated information is then combined to form predictive safety indicators and assess risk.”
