Truck Crash Facts (Jan 2020, 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 e...

 

The objective of this report is to provide a benchmark for elevator managers in assessing performance, and supply a source for recognizing trends in the characteristics of North Dakota elevators. This report and the statistics mailed to individual elevators are presented as a source of information for...

 

This report presents the feasibility of a novel anchor system that mitigates the end-peeling of carbon fiber reinforced polymer (CFRP) sheets used for strengthening reinforced concrete beams. Contrary to conventional anchoring methods, CFRP sheets are embedded inside the pre-grooved concrete and covered...

 

This report represents a continuation of analysis concerned with the patterns and methods of distributing grains and oilseeds from North Dakota. The collection and compilation of this type of data began in 1956-57. The objectives of this report, like prior reports, are to provide the necessary database...

 

This study developed a number of models to estimate the relationships between land use, transit ridership, household expenditures, and municipal spending, with a focus on small urban areas. First, a regression model was developed that estimated transit ridership in small urban areas as a function of...

 

The existing online mapping systems process many user route queries simultaneously, yet solve each independently, using typical route guidance solutions. These route recommendations are presented as optimal, but often this is not truly the case, due to the effects of competition users experience over...

 

Reinforced concrete bridge wall piers constructed using older codes perform inadequately during strong earthquakes; deficiencies include short reinforcement lap splices, insufficient steel reinforcement ratios in the longitudinal and transverse direction, and inadequate seismic detailing. Three half-scale...

 

While the automobile industry is rapidly transitioning towards automation, the transit industry in the United States has recently begun investigating automation in transit operations. Multiple U.S. transit agencies have been experimenting with various automation technologies in transit vehicles. Examples...

 

In Wyoming, most county paved roads were built decades ago without following minimum design standards. However, the recent increase in industrial/mineral activities in the state requires developing an efficient pavement management system (PMS) for local paved roads. The new PMS which is currently being...

 

Fourteen Thin Lift Treatments (TLTs) in Utah's Department of Transportation (UDOT) Region 2 were evaluated over a five-year period in order to assess their performance. Surface distress data was quantified using Pavement Condition Indices (PCIs), and Remaining Service Life (RSL) were estimated following...
