Hyperspectral remote sensing is an emerging field with many potential applications in the observation, management, and maintenance of the global transportation infrastructure. This report describes the development of an affordable framework to capture hyperspectral images and models to classify the images....
Trucks are a vital part of the logistics system in North Dakota. Recent energy developments have generated exponential growth in the demand for truck services. With increased density of trucks in the traffic mix, it is reasonable to expect some increase in the number of crashes. Analysis shows however...
Transportation agencies use a variety of methods to evaluate the condition of pavements and the characteristics of their use. Methods range from in-pavement sensors to ride quality characterizations that require specially instrumented probe vehicles. However, the extensive labor, specialized training...
The sharp increase in travel volumes, shift in traffic mix, and large increases in crashes have transformed the traffic environment in the oil region of western North Dakota. Roads once used for local access and agricultural purposes now regularly serve the energy sector. Oil companies, workers, commercial...
Concrete has been used in dams, bridges, and highway pavements in which freeze-thaw process and cyclic loading are considered as important factors affecting its mechanical behavior during its service life. Damage caused by frost expansion is a primary concern when designing concrete structures in cold...
This report presents a research examining the feasibility of creating an integrated structural health monitoring and impact/collision detection system for bridges in remote cold regions, where in-person inspection becomes formidable. The research report includes a theoretical analysis of the impact event...
Older drivers are overrepresented in motor vehicle crash fatalities. As the U.S. population continues to age, this problem will grow. Health care providers (HCPs) are in a position to provide their older patients with education which may prevent further motor vehicle fatalities. Rural older adults are...
Many Native American tribal governments are lacking in emergency preparedness, a part of the emergency management cycle where planning for disasters happens. These governments need assistance planning for future disasters. Federal, and state governments, along with other agencies and organizations, have...
North Dakota currently designs roads based on the AASHTO Design Guide procedure, which is based on the empirical findings of the AASHTO Road Test of the late 1950s. However, limitations of the current empirical approach have prompted AASHTO to move toward the new mechanistically based pavement design...
The sharp increase in travel volumes, shift in traffic mix, and large increases in crashes have transformed the travel environment in the oil region of western North Dakota. Roads once used for local access and agricultural purposes now mostly serve expanding oil production. Oil companies, workers, commercial...
