Driving 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....
Commercial motor vehicle (CMV) enforcement efforts seek to make travel on public highways safer. CMV enforcement professionals secure compliance of CMV's with state laws regulating weight of commercial vehicles to protect state highways from unnecessary damage, and ensure payment of necessary registration...
Seat belt use on rural roads is especially important due to the relatively high risk for injury compared to urban areas. In the northern plains, where nearly 90% of travel occurs on rural roads, addressing this issue is particularly critical. A cohort group of 32 states was used to study seat belt use...
North Dakota's rural roads are vital social and economic connectors. These roads, however, are associated with relatively high crash injury risk. While a multitude of efforts is underway to reduce crash risk through road improvements and vehicle technology, seat belts offer an immediate and low-cost...
Seat belts are a primary motor vehicle safety device. Studies have shown that seat belts not only decrease the likelihood of being injured in a crash, they also save lives (Abdel-Aty, 2003; Yamamoto and Shankar, 2004). Because of this, seat belt use is a primary concern of traffic safety professionals....
Investigations into the effects of the addition of vertically-oriented shear spikes with fiberglass reinforced polymer rods have shown that the shear spikes increased the effective stiffness of the stringers of a full-scale timber bridge chord specimen. This was previously found to be true on dimension...
Congestion in Salt Lake City is showing an increasing trend and, as congestion reaches higher levels, benefits of the HOV lanes will also increase. It needs to be determined whether the Salt Lake Valley HOV lanes are performing effectively in terms of travel time benefits, safety and the ability to carry...
This research project, "Evaluating and Improving Pedestrian Safety in Utah," was initiated in December 2000. Two interim reports have been prepared thus far, including Facilitation of Pedestrian Crossings in 28 States and Literature Review of Pedestrian Safety Measures (Cottrell 2001) and Literature...
This paper summarizes the results of a study on direct assessment of rural user needs in Montana, North Dakota and South Dakota. The objective was to assess rural road users and providers perceptions of rural road needs. Different rural road user groups were identified to obtain a representative sample...
The objectives of this research were to determine if fly ash has an effect on the field performance of cement-treated bases, determine if cement-treated bases perform similarly to other base types, and develop pavement performance models for interstate and non-interstate roadways in the state of Wyoming.
