Filter by Keyword18 report(s) found with databases in the keywords field 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.... This report describes the different programming functions used now and discusses future programming issues. 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 objective of the Short Line Railroad Database (SLRD) system is to provide a partial, if not a complete solution. It attempts to set up a framework for establishing and maintaining a standard database for Class II and Class III railroads that would serve as a Personal Computer (PC) data system with... This project examines the feasibility of developing a model from other data to ascertain the likelihood of a certain safety rating. This would enable efforts to be concentrated on the motor carrier firms with the least probability of achieving a Satisfactory rating and reduce the need to visit every... The railroad industry uses a variety of information and data sources to present planners and decision makers with the best environment facilitating the decision process. The management of this information and its environment is vital to ensure that decision makers have an operational framework allowing... The purpose of this report is to describe the R-1 database and a series of programs written to manipulate the data files. These programs were used in a recent research project to generate a time-series database of railroad expense, investment, and operating data. The time-series database was used to... The development and use of transportation databases is an essential prerequisite to transportation and marketing analysis. In few other disciplines are the databases so scattered and uncoordinated as in the field of transportation. Yet, there are few disciplines which are so data-dependent, particularly... |
