View AllInnovative lane management offers the opportunity to levy fees for the premium road space. Express Lanes in Utah offer road users reduced journey times for a fee. The Utah Department of Transportation (UDOT) has converted the High Occupancy-Vehicle (HOV) lanes on Interstate 15 (I-15) from 600 North Street... Seat belt use is an important aspect in the safety of newly licensed teen drivers. Yet, crash statistics suggest that belt use rates are well-below the desired 100 percent rate. Belts were used by only 73 percent of teen drivers in injury crashes on rural Cass county roads during recent years. Educating... Seat belt use is an important factor in teen safety because 3 of every 4 unintentional deaths among ND teens results from a crash. Yet, crash statistics suggest that seat belt use is well-below the desired 100% rate. Seat belts were used by only 73% of teen drivers in injury crashes on rural Cass county... The analysis describes world trade in containers by country, through time, by importers and exporters, and by port areas. In addition, it includes an analysis of containerization of cargo. Specifically, we used the data to analyze the extent that cargos that traditionally were shipped in bulk, have become... For North Dakota teens, three of every four deaths are from motor vehicle crashes. Injury crash records for teen drivers were studied to gain insight regarding driver, vehicle, and road factors for public safety policy and program discussions. Results show 14-year-old drivers are three times more likely... 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. Untreated native soil with high swell potential has been identified by the Colorado Department of Transportation as one of the major contributing factors in the development of premature longitudinal cracking and other pavement distresses in Colorado (Ardani et al. 2003). Unique regional factors such... The impetus of this research is to meet the growing need for accurate and practical methods to support traffic analysis in work zones. This research examines the application of two classes of traffic analysis models, macroscopic sketch analysis and microscopic traffic simulation, to work zones. The research... This report represents a continuation of analysis concerned with the patterns and methods of distributing grains and oilseeds from North Dakota. This series began with the analysis of 1956-57 data and was published in Agricultural Economics Reports 15, 17, 44, 56, and 86 and Agricultural Experiment Station... High Performance Steel (HPS) is a superior material with higher yield strength, improved weldability, greater levels of toughness, and improved weathering resistance that can lead to more economical bridges than conventional steel bridge designs. AASHTO Load and Resistance Factor Design (LRFD) provisions... |
