FREIGHT CAR DEMAND INFORMATION AND FORECASTING RESEARCH PROJECT. PHASE II
Freight car demand information and forecasting systems have become increasingly important to the centralized car distribution procedures that have developed in the railroad industry. During Phase II, a forecasting system was developed which incorporated the recommended features from Phase I (report dated March 1975). The objective of Phase II was to test the accuracy of the recommended system in practice and to determine the feasibility of implementation. Several conclusions were reached, including: (1) Car order information, field forecasts, and loadings information can be obtained and a forecasting system developed at a relatively low cost. (2) The resulting forecasting system can forecast a composite measure of demand at an 80 to 95 percent accuracy rate on a week-to-week basis. This report documents these conclusions and others and presents the results of the various forecasting approaches developed.
