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... 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 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... As the population grows and travel demands increase, alternative interchange designs have become increasingly popular. The diverging diamond interchange is an alternative design that has been implemented in the United States. This design can accommodate higher and unbalanced flow and improve safety at... Improving roadway safety on Indian reservations requires a comprehensive approach. Limited resources, lack of crash data, and few cross-jurisdictions coordination has made it difficult for Native American communities to address their roadway safety concerns. A methodology to improve roadway safety has... Engineering economic analyses (EEA) apply economic methodologies to engineering problems for decision-making support. When conducting an EEA, interest and inflation rates are the two critical factors. Using inappropriate values for interest and inflation rates could affect decision-making, such as unfairly... The trucking industry continues to contribute significantly to the economy of the United States. The surface transportation system has been a critical component for the movement of goods and services by the trucking industry across the country. Recent decades have seen substantial growth in freight miles... |
