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...
This report is the response to the North Dakota Legislature's request for a study of the transportation infrastructure needs of all counties, townships and tribes in the state. In 2019, the North Dakota Legislature advanced HB 1066 which had a provision for funding distributions to non-oil producing...
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...
During area-wide episodes of poor air quality, people may reduce their transportation-related emissions by driving less, reducing their exposure to emissions by walking/bicycling less, or going about their lives as usual. These three reactions have different consequences for transportation, health, and...
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...
An efficient and safe transportation system is essential to communities during the long-term recovery period after earthquakes. A disrupted transportation network due to infrastructure damage or failure affects the functionality of the traffic system and poses increased traffic safety risks. A rational...
The rapid increase in traffic volume and heavy vehicle loads is causing accelerated deterioration of pavement infrastructure worldwide. This research investigates the impact of overweight and dynamic axle loads on pavement performance, employing advanced weigh-in-motion (WIM) systems and machine learning...
Transportation planning, traffic monitoring, and traffic safety analysis require detailed information about pedestrian volumes, but such data are usually lacking. Fortunately, recent research has demonstrated the accuracy of pedestrian volumes estimated from push-button data contained within high-resolution...
Reliable intersection-traffic data are essential for transportation planning, operations, and safety. The City of Bismarck relies on targeted short counts, which is the predominant, albeit outdated, type of intersection traffic data collection. The city recently updated its signalized intersection equipment...
