This study was designed to be a resource for producers, shippers, and exporters seeking to diversify their markets through IP shipments. Included are examples of markets for IP grains, trends for containerized movements of grain, and general logistical information to provide a base for understanding...
Traffic control alternatives associated with reconstruction projects on a rural interstate have been investigated in this research. Slab replacement projects, milling/resurfacing projects, and traffic controls in the vicinity of interstate ramps were analyzed. The recommendations obtained from a national...
In this study, the researchers evaluated the performance of asphalt mixes prepared using the Marshall mix design method and the Superpave level one mix design method. The Georgia Loaded Wheel Tester and the Thermal Stress Restrained Specimen Tester were used to test the rut-resistance and low-temperature...
This research developed a methodology to optimize roadway access intersection design using an expert system to guide design in accordance with published criteria, a graphical multi-criteria evaluation system, which revealed marginal impacts of changing design parameters across three objective functions...
This paper estimates railroad and truck shipment costs for several major commodities and illustrates how public data and analytic tools can be used to analyze multimodal trade-offs and efficiencies.
Some North Dakota counties are facing a shortage in quality gravel. Other counties may experience the same problem in the near future. Gravel pits in the state are scarce and counties consume substantial amounts of gravel for a large portion of their roads. Obtaining gravel from distant sources leaves...
The results of an erosion control testing study are presented in this report. The purpose of the study was to compare the performance of selected erosion control products under simulated rainfall and sunlight conditions in terms of soil loss reduction and vegetation growth. A total of 19 materials--11...
The goal of the present study is to improve the effectiveness of highway safety inspections of motor carriers. This project evaluates the differences, if any, between violations found during the two broad classifications of inspections (anticipated or spontaneous). The data used are taken from all the...
The overall objective of this study was to complete a comparative analysis of firms and economic development specialists' attitudes about the importance location factors in North Dakota, South Dakota, and Nebraska. Results indicated that overall, state and local taxes ranked first, infrastructure ranked...
This project included two laboratory studies and analytical work dealing with T-beams comprised of a concrete flange connected to a wood beam plus plywood sheathing. Based on the experimental results of tests of 72 slip specimens and 4 full-scale layered T-beams, the mechanical behavior of different...
