Filter by Keyword9 report(s) found with databases in the keywords field 1 - 9 of 9 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... 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 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... This project is dedicated toward creating an annual information base on short line and regional railroads. Three years of collection and analysis of this data is complete, with another year in process. In this report, techniques for collecting short line information by mail and electronically are discussed.... 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... |
