Transitioning from Reactive Planning to a Fast Loop

During the core "Problem Identification" phase of THSP development, SHSOs are required to analyze statewide data to identify where crashes are happening, who is involved and why, and to prioritize funding accordingly. Traditional crash data limit this process due to a small sample size, particularly on rural and local roads, where fatal crashes are too infrequent. This means that statistically reliable patterns can’t be established until multiple years of data are accumulated.

TRA identifies dangerous conditions with highly granular geographic and behavioral precision. SHSOs can use hotspot analysis to isolate corridors where risks are occurring now. For example, if TRA identifies a sudden, localized spike in risk at a specific location, the SHSO can immediately prioritize that corridor in the THSP for grant funding and deploy the most appropriate intervention to help prevent crashes from happening.

Distracted driving is a primary target for behavioral highway safety grants, yet it is chronically under-reported due to its reliance on self-reporting or officer observation post-crash. This makes it incredibly difficult for SHSOs to set accurate benchmarks for anti-distraction programs using traditional data.

Speed management is a foundational element of road safety. Traditionally, highway safety professionals conduct speed studies by deploying pneumatic road tubes, while law enforcement officials use radar equipment at a single location for a limited time. In both cases, a brief, localized snapshot of driver behavior is captured.

Federal regulations require SHSOs to engage in meaningful public participation and engagement (PPE), with particular attention given to road users and communities that are overrepresented in crash data. This includes vulnerable road users (VRUs) such as school-age children.

Because the THSP covers three years, the roadway environment will change significantly over the life of the plan. Multi-year construction projects and temporary detours introduce sudden changes to road geometry and traffic flow that legacy crash data will miss entirely.

Intersections are complex, high-conflict zones that may require the use of engineering, education and/or enforcement strategies to improve their safety. To break down the silos between behavioral programs (funded through the National Highway Traffic Safety Administration) and infrastructure (funded through the Federal Highway Administration), SHSOs can bridge the gap between why a project is constructed and how it should be used to advance safety.

A key requirement of the THSP is the submission of an Annual Grant Application, which includes evaluating the effectiveness of funded countermeasures year-over-year. In the traditional "Slow Loop," data delays make it impossible to determine in real-time whether an intervention deployed in year one of the plan is effective by year two.
