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...
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...
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...
Train-pedestrian conflicts result in a substantial number of serious and fatal injuries annually. Signs indicating safe and permissible behaviors near railroad rights-of-way are commonly relied upon to mitigate collisions. However, the effectiveness of these signs in preventing accidents depends on the...
Winter storms significantly increase crash risk and disrupt travel, especially under extreme conditions. Gusty winds, heavy moisture, and low temperatures can quickly make travel dangerous in the Northern Plains. This study was aimed at understanding winter truck crashes, given the prominence of commercial...
Public education and outreach activities increase the effectiveness of work law enforcement does to prevent large truck-involved crashes. This demonstration project was conducted through two components including a primary education program and a complimentary education program designed to be executed...
