To evaluate alternative modes for distributing commodities to markets, the relevant distribution system must be identified. The basis for choice between modes for a specific commodity movement will be based on total system costs, including line-haul transport, transfer and storage, and such items as the value of time in transit. System evaluation should also consider transport capacity and competitive sources of commodity supply to serve the market under study. For specific movements, suitable data on commodity flows and transportation costs will generally not be available to most investigators. Recognizing that most traffic moves on the basis of current rates, not costs, modeling of transportation distribution systems will be imperfect. Problems in identifying system components and satisfying data requirements are examined.
