Estimating drilling locations plays an important role in forecasting truck trips derived by hydraulic fracturing oil development for long-range transportation planning. Predicting drilling locations among more than 7,000 oil drilling lands shows a random pattern with uncertainty. Twenty-year multi-period...
Because of the importance of safety, and the potential benefits for both the general public and the commercial vehicle industry of improving safety, the main goal of this project is to identify those commercial vehicle-related technologies that, through successful adoption, have had a positive impact...
Secondary rail market prices for guaranteed grain service provide insight regarding U.S. rail service available to grain shippers. This analysis investigates alternative market information that may enhance indicators offered to gauge current and expected rail grain service levels. Regression analysis...
In this research the feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated. The study consisted of modifying the GLWT to handle 15.2 cm (6-in.) cores, obtaining asphalt pavement cores from several test sites throughout Wyoming, collecting rut...
This report describes a study to evaluate the use of subgrade resilient modulus for the design of flexible pavements. The objectives of this initial study were to: a) investigate the relationship between resilient modulus and R-value, and b) develop a predictive equation for resilient modulus based on...
