View AllDriving under the influence is a dangerous activity and is especially problematic in North Dakota. To curtail rates of impaired driving, it is important to examine the actions of those that have firsthand involvement with DUI prevention: prosecutors, community leaders, and law enforcement personnel.... Motorcycle use brings increased risk to the operator simply by the nature of the vehicle. When a crash occurs, the threat of injury or death is magnified by physical exposure compared to that of other vehicle occupants. Detection and gap/speed judgments by other motorists present additional hazards to... Western North Dakota continues to experience an economic boom due to energy industry expansion. Roads once used only for local access and agricultural purposes are now being used at high volumes to serve expanding oil production. The motivation for this report is a proposed new microelectromechanical systems (MEMS) sensor with applications in civil infrastructure sensing. This report analyzed the influence of three assumptions employed in the Euler-Bernoulli, Rayleigh, and Timoshenko beam theories by comparing their results to... In this study, we estimated the travel response time between the ambulance locations and the demand points and between the demand points and the hospitals. The estimation was conducted in Geographic Information Systems (GIS) by utilizing the shortest path algorithm. The demand points were randomly generated... North Dakota's rural roads provide vital social and commercial links for a widely dispersed population. The safety of these roadways is paramount in managing traffic assets to enhance the state's livability. Approximately 67% of the state's travel, in vehicle miles, takes place on rural roads. From a... Truck Crash Facts (Oct 2013, Issue Brief) Trucks are an important mode of economic connectivity in rural states like North Dakota. The size/mass difference between 80,000 pound trucks and 4,000 pound passenger vehicles, along with operational differences such as acceleration/deceleration times and turning radiuses, heighten risk for crash events. North Dakota truck injury crash incidence, in terms of injury crashes per VMT, increased 80% between 2002 and 2012. As part of a study to develop design guidelines for integral abutment bridges, a study was undertaken in which the bridge movement of the 400 South Street Bridge was surveyed for one year to quantify changes in bridge movement due to temperature variations. These quantitative bridge movements were compared... This document presents the application of the Highway Safety Manual (HSM) for rural local two-lane two-way highway segments in South Dakota. The calibration was based on three-year (2009-2011) crash data from 657 roadway segments constituting more than 750 miles of roadways. The calibration process includes... |
