Filter by Keyword144 report(s) found with analysis in the keywords field Since 1980, over 200 new local or regional railroads have been established in the United States, mostly through the sale of light-density lines by Class I carriers. With these new additions, this sector of the railroad industry now numbers over 400 strong. Collectively, these firms operate over 40,000... 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... This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the effect of construction Profilograph Index (PI) values on long-term roughness measurements of concrete pavements. The objectives of this study were to determine if increased... 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... The GEOTRANS (GEographical Optimizer for TRANSportation) is an implementation of a GDSS for rural transportation. Algorithms and specialized data structures were developed to accomplish accurate and efficient solutions of a suite of network flow optimization models for use in GEOTRANS. The design of... The information needed to plan and operate transit services for people with disabilities is little known to transit agencies and also difficult to obtain. This report is based on a study that was undertaken to determine the travel patterns and transportation needs of people with disabilities, and also... A research study was conducted to investigate the potential application of Intelligent Vehicle/Highway Systems (IVHS) technologies for reducing accidents on rural roads. After studying existing technologies, their present application to transportation, and approaches to identifying predominant accident... This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the factors influencing the determination of a subgrade resilient modulus value. The objectives of this study were to first, investigate the importance of several fundamental... 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... This study examines consolidation of road services by local governments, and explores the optimal mix of roads for rural counties. A methodology for measuring economies in the provision of local road services is presented. This methodology is unique in two ways; 1) it better accounts for relevant variables... |
