The first objective of this project was to evaluate the literature to gain a better understanding of the safety implications of commercial motor vehicle (CMV) operations by deaf and hard of hearing drivers. The second objective was to identify and document procedures and recommendations that can be safely...
Considering traffic safety concerns and challenging driving conditions on Interstate 80 in Wyoming, the United States Department of Transportation (USDOT) and Federal Highway Administration (FHWA) selected an I-80 400-mile freeway corridor as one of the three sites in the United States to develop, test...
Tribal communities recognize the need to improve roadway safety. A five-step methodology has been developed by the Wyoming Technology Transfer Center (WYT2/LTAP) to improve roadway safety on reservations. This methodology was initially implemented on the Wind River Indian Reservation (WRIR), which led...

Federal and state transportation agencies set goals related to surface transportation system performance. The variability in factors influencing design criteria (e.g., driver performance, road conditions, and vehicle performance) is often large and is addressed implicitly by using "conservative" values....
This study evaluated the approach-level safety performance of left-turn phases at signalized intersections, including permissive, protected-permissive (PPLT), protected indications, and flashing yellow arrow (FYA). Data collection included exact dates of traffic signal changes, high-resolution datasets...
The 24/7 Sobriety Program is an intervention strategy mandating that impaired driving offenders remain sober as a condition of bond or pre-trial release. The goal is to monitor the most at-risk offenders in North Dakota and require that these individuals remain sober in order to keep roadways safe from...
The State of Wyoming road network is characterized by heavy truck traffic. In 2015, truck traffic was approximately 22% of vehicle miles traveled (VMTs) along all routes in Wyoming, according to the WYDOT Annual Traffic Report. The heaviest truck traffic exists along I-80 with about 47% truck VMTs. Trucks...
