Since early March 2020, the COVID-19 pandemic has had significant impact on traffic across the United... Regular inspection and maintenance of culverts are critical to ensure the safe functioning of transportation infrastructure systems, preventing injuries, loss of life, and significant financial damage. Various state departments of transportation (DOTs) and the American Association of State Highway and... This report documents the effort to develop a practical relation between the cracking tolerance index and portions of the dynamic modulus curves of asphalt mixtures. A review of practices used to create asphalt mixtures dynamic modulus master curves, based on NCHRP reports and other relevant literature... The statewide driver traffic safety survey provides baseline metrics for the Highway Safety Division and others to use in understanding perceptions and self-reported behaviors related to focus issues. A core set of questions addressed nationally agreed upon priorities, including seat belts, impaired... Precipitation-induced landslides pose risks to humans through property damage, disruption of infrastructure, injury, and loss of life. These risks may be altered by climate change, as changes in vegetation cover and associated root cohesion might lead to a change in areas susceptible to landslides. We... 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... The objective of this research is to compare the level of public transportation services provided in North Dakota to those of surrounding states. The study focuses on North Dakota, South Dakota, Montana, Wyoming, Nebraska (excluding the Omaha metro area), and Minnesota (excluding the Twin Cities metro... A survey of farm operators in the Central Plains Region, including Illinois, Indiana, Iowa, Kansas, and Nebraska, was conducted to gather information about transportation of crops, the inventory and characteristics of farmer-owned truck fleets, and on-farm storage capacity. The objective of the study... Truck crashes on steep downgrades caused by excessive brake heating is an ongoing concern for the Wyoming Department of Transportation (WYDOT). Crashes resulting from brake failure on downgrades cause a devastating toll on lives and property. To counter such crashes, WYDOT initiated a research project... |
