  1. Regional Routing Model Review: A) Data Fusion Efforts and Issues Frank Southworth Oak Ridge National Laboratory Oak Ridge, TN 37831 NETS Program Review December 12, 2005 Washington DC

  2. 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

  3. Commodity Production Estimates/Reports by County (O-C) Input-Output Model-Based Consumption Estimates, by County/Port (D-C) Annual tons shipped by by truck (O-D-C-M) On-site Consumption Conversion to County-to-County Shipments Annual tons shipped by by water & rail (O-D-C-M) O-D-C-M tons shipped annually between US Counties/Ports Truck Dray Model Traffic Route Assignments (O-D-M-R) transit times, distances Shipper generalized cost (utility) functions (O-D-C-M) NETS Shipper Mode/Route /Market Choice Models Computed Flows, Costs and Benefits Creation of a Base Case (CY 2002) STB Station-to-Station Rail Shipments USACE Domestic Dock-to-Dock & Foreign Port-to-Port Waterway Shipments ORNL Multimodal Transportation Network O-D-C Rates Data: USACE/TVA (water) STB (rail) USDA, Other (truck)

  4. Estimated U.S. Corn Production and Consumption by County, 2002

  5. Waterway Rate Mapping Examples Data Issue: Rates Needed for Western Rivers

  6. National Highway Network Database Global Seaways Network Database Intermodal, Truck, and Ports Terminals Databases National Rail Network Database National Waterway Network Database Operational Waterways Network Database Operational Rail Network Database Combines Inland , Coastal, Great Lakes & Trans-Oceanic Links Unified North American Multimodal Freight Network Southworth & Peterson, 2000

  7. North American/Trans-Oceanic Multimodal Freight Network

  8. An Intermodal Terminal Representation

  9. direction of travel transfer terminal rail line haul Railroad #2 Railroad #1 interline truck dray Route cost = modal line-haul travel costs + intra-terminal transfer costs + inter-carrier (interlining) costs + truck drayage costs origin destination “cost” = function (freight rate + transit time) Example of costs associated with a truck- rail intermodal movement

  10. Examples from Locating Waterway Docks along Navigable Rivers Data issue: Not all docks are geo-coded (and which side of the river are they on?)
