The Federal Motor Carrier Safety Administration awarded North Carolina State University $843,619 on December 1, 2025, under the Motor Carrier Safety Assistance High Priority Activities Grants and Cooperative Agreements program (CFDA 20.237) to evaluate North Carolina's T.R.A.F.F.I.C. (Together Reducing Accidents Fatalities Fatigue Interstate Corridors) program's impact on commercial motor vehicle crashes, speeds, and weight violations.

The project will assess the effectiveness of high-visibility CMV enforcement through nine structured tasks, including retrospective and prospective data analyses. Work includes deploying speed sensors, collecting crash and weight data, and comparing outcomes across treatment and control corridors using Bayesian methods. Findings will inform enforcement strategies and multi-state efforts to improve CMV safety.

Performance runs through September 30, 2028, with work conducted in North Carolina. The source indicates the applicant's original three-year project duration exceeded the prescribed two-year performance period, resulting in a pro rata reduction of $73,635 from the total award amount.

The proposed project will evaluate north carolina's together reducing accidents fatalities fatigue interstate corridors (T.R.A.F.F.I.C.) program's impact on CMV crashes, speeds, and weight violations to inform similar enforcement efforts. The project will evaluate the effectiveness of high-visibility CMV enforcement program through a series of nine structured tasks, including retrospective and prospective data analyses. Also, the project involves deploying speed sensors, collecting crash and weight data, and comparing outcomes across treatment and control corridors using bayesian methods. The findings will guide enforcement strategies and inform future multi-state efforts to improve CMV safety. Reduction narrative ($73,635): the prescribed period of performance is two years; however, the proposed project is three years in duration, ending in september 2028. Thus, the applicant agreed to a pro rata reduction by 1/3.
