REPRESENTING INDUSTRY AND POPULATION STRUCTURE FOR ESTIMATING FREIGHT FLOWS

This paper presents and demonstrates a method for representing the urban industrial structure and predicting the annual usage rate of commodities by industry and by firm size. It also describes a scheme for grouping industries in sectors and treating the interindustry linkages between these sectors logically. Predictions are made in such a way that they will be consistent between commodities and between industries. Computations are simple and feasible using data that exist for any area in the U.S. The approach should be a powerful tool in attacking the problems of urban and regional structure, industry interaction, and various other areas as well as serving as a basic input to freight-demand forecasting.
