The diverging diamond interchange (DDI) and the continuous flow intersection (CFI) represent significant innovations in roadway design, offering superior operational performance and enhanced safety compared with conventional signalized ramp terminals and intersections. This study conducts a comprehensive...
Truck platooning, a technology where connected and automated trucks travel in closely linked convoys, promises significant reductions in fuel consumption and emissions. However, these long convoys present a major safety hazard on existing roadways, particularly on rural two-lane undivided highways. On...
The statewide driver traffic safety survey provides baseline and longitudinal metrics for the Highway Safety Division and others to use in understanding perceptions and self-reported behaviors related to focus issues. A core set of questions addresses nationally agreed upon priorities, including seat...
The present study examines the impact of autonomous vehicles (AV), driverless vehicles (DVs), and other on-board safety technology (OBST) on safety and safety culture in an operational environment. Data were gathered utilizing survey and interview methodologies to gather qualitative data from survey...

North Dakota’s seat belt use study provides statistically reliable data from a field survey of driver and right front-seat passenger seat belt use. This data can be used to develop generalizations, comparative analyses, and recommendations. This National Occupant Protection Use Survey (NOPUS) is based...
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...
The preservation of road safety in snowy regions during the winter season is of paramount significance due to the presence of perilous meteorological circumstances, such as snowstorms, which can result in escalated vehicular collisions and subsequent roadway closure. In the present investigation, our...
Early research suggested protected left-turn signalization had clear safety benefits over permissive left-turn signalization. Yet, subsequent research on when and where to use protected left-turn signalization focused more on vehicle delay and throughput than on safety. Based on such studies, it would...
Extreme wind conditions can be a formidable foe to both highway and driver safety. Strong gusts increase the likelihood of wind-induced vehicle crashes, especially for high-sided vehicles (i.e., semi-trucks) in the United States. Current understanding of wind loads on high-sided vehicles comes mostly...
