Filter by Keyword135 report(s) found with roads in the keywords field The study demonstrated that short lines could achieve greater cost savings if they were to increase their density (revenue ton miles per mile) and their size (mile of road). Size is an important criterion that a short line must examine when evaluating the purchase of a new section of track. However... This study provides a snapshot of truck/rail container intermodal shipping into and out of North Dakota. The study revealed the benefits of intermodal transportation including lower overall transportation costs, increased economic productivity and efficiency, reduced congestion and burden on over-stressed... This report presents results of an investigation into the practice and legal issues of Road Safety Audits and Road Safety Audit Reviews (RSAs and RSARs). These safety analysis approaches focus on identifying safety issues of proposed projects (RSA) and existing roadways (RSAR). In the United States... The objectives of this research were to determine if fly ash has an effect on the field performance of cement-treated bases, determine if cement-treated bases perform similarly to other base types, and develop pavement performance models for interstate and non-interstate roadways in the state of Wyoming. This study examines the cost implications of mergers and competition over existing rail lines by testing for the condition of cost subadditivity. That is, can industry output be provided at a lower cost by one firm than by more than one firm? Future customer demands, service availability, and industry investment decisions will shape the modal marketing decisions of the grain marketing sector. The Delphi survey technique is used to engage a cross-section of grain industry experts in sharing opinions regarding future trends for service, investment... An economic engineering model was developed to estimate start-up and operating costs of an intermodal facility located on a short line railroad. The model developed in this study has many useful features. Costs can be estimated for different equipment configurations and sizes of facilities. Sensitivity... This project was initiated to develop and select advanced computer programs to improve roadway hydraulic and hydrologic design tools available for use by UDOT engineers and consultants. The development and selection of such computer software that utilizes engineering analysis along with interactive graphics... While SafeStat was designed to prioritize carriers for monitoring and compliance reviews, the ISS was designed to prioritize carriers for roadside inspection. However, both algorithms use similar data to define a relatively unsafe carrier. It would be beneficial if there could be one uniform motor carrier... Six major railroads provided the Transportation Technology Center Inc. (TTCI) with defective rail that had been removed from service. The rail, which contained a variety of defects, was placed into a gauntlet track at the Transportation Technology Center (TTC). This paper is the assessment of those six... |
