Filter by Keyword104 report(s) found with design in the keywords field Soils are an important component of any transportation structure. To improve the engineering properties of these soils, compaction requirements are included in virtually all transportation construction specifications. Field observations indicate however, that soils at near-freezing temperatures may require... This document is the second in a series of three manuals produced for the South Dakota Department of Transportation. It is intended for use by county superintendents and other county roadway agency personnel within the State of South Dakota for the efficient selection of maintenance, rehabilitation... Manuals of instruction are important engineering tools because they provide the necessary information to perform important design procedures and calculations correctly and accurately. The objective of this project was to develop a computer-based manual of instruction by implementing tools and techniques... 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 primary objective of this research was to establish statistically valid mathematical models that can explain the variations in accidents as a function of geometric variables. Engineers and planners will be able to use these models to examine the sensitivity of accident rates to any of the independent... In this research, criteria were developed for designating and evaluating scenic loop tours based on roadway conditions, scenic beauty, number of local communities, population, and anchor attractions. Two existing scenic loop tours in Wyoming -- the Cheyenne and Oregon Trail Loop Tour and the Bighorns... Often in traditional design procedures, a designer sketches results which are based on computer applications and transmits this information via hardcopy to a drafter, who reenters it into a CAD system. The inefficiencies are clear and an obvious opportunity exists for productive gain. Recent work by... This documentation includes detailed information on each subroutine used to draw the entities supported by UWGRAPH. These descriptions include the definitions of the arguments, an example of the subroutine usage, and a graphical illustration of the arguments. Compilation instructions are included for... This study was initiated by the Bridge Branch of the Wyoming Transportation Department to provide direction in optimizing CAD usage. Critical issues in managing computing resources in a design operation are staffing, maintaining, and financing a highly dynamic system. Managing such a system properly... Often, a traditional design procedure is used wherein a designer sketches results which are based on computer applications and transmits this information via hard copy to a drafter, who re-enters it into a CAD system. The inefficiencies are clear and an obvious opportunity exists for productive gain.... |
