O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY Prototype Database Development Involves: 1) Data Collection, Data Fusion, Commodity Flow Estimation and Traffic Routing for 5 Agricultural Commodities: Corn Wheat Soybeans Apples Processed Poultry 2) Development of Origin-Destination-Commodity-and-Mode Specific Freight Rates and Transit Times to go with these Movements And 3) Identification of Data Problems That Need to Be Fixed
