Filter by Keyword18 report(s) found with databases in the keywords field This report presents several advancements in the empirical modeling of liquefaction-induced lateral spread. It starts with a newly collected dataset of 5,560 historical lateral spread displacement vectors, a sample size over 10 times larger than the existing databases and subsurface data comprising over... A study of collisions occurring at intersections along State routes in Utah was conducted. The number of crashes, the crash severity score and, for selected locations, the crash rate were determined and "ranked" for intersections within the Utah Department of Transportation's Region 1, Region 2, Region... Advances in computers, telecommunications, and information system technologies have led to the development of a wide range of applications that can improve the efficiency and quality of service for all forms of transportation, including public transit. These developments provide additional tools to help... The objectives of the library of a Rural Transit Assistance Program (RTAP) are to promote the effective operation of public transit systems while efficiently utilizing public and private resources and to continually improve the quality and availability of resources and technical assistance to rural transit... State Highway Agencies (SHAs) in the United States use smoothness specifications to insure that they are providing the public with quality roads. Monetary incentives / disincentive policies based on the initial roughness values are used by SHAs to encourage contractors to build smoother roads. To justify... This project investigates alternate forms of dissemination for the accident information. Costs, capabilities, and compatibility are reviewed for integration of the accident database with a GIS format to allow a graphical and spatial interface. The issues being addressed by this research focus on information... This study was conducted to determine if efficiencies could be gained through the process of standardizing data storage mechanisms to permit diversity at the operating level while maintaining data compatibility for aggregation at higher levels in the organization. Transportation agencies use many computer... This report describes the Access database created to automate some of the tedious work required to process information requests from the U.S. Department of Agriculture's Ag Export Assistance program. The main functionality requested for this automation project were: (1) store present and historical ocean... This report describes the development of a Standard Modular Data Storage System. Features such as inventory data, pavement management data, and other maintenance data can be organized as modules in a common data repository. This repository can be imported into an enterprise database such as Informix.... A variety of computer tools are being used by UDOT to serve diverse maintenance management needs. Many of the tools are individually tailored for a specific purpose and lack the functionality to share data with other applications. This has resulted in the establishment of numerous databases which are... |
