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

2 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

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

4 O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY Estimated U.S. Corn Production and Consumption by County, 2002

5 O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY Waterway Rate Mapping Examples Data Issue: Rates Needed for Western Rivers

6 O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY National Highway Network Database National Rail Network Database National Waterway Network Database Global Seaways Network Database Operational Waterways Network Database Intermodal, Truck, and Ports Terminals Databases Unified North American Multimodal Freight Network Southworth & Peterson, 2000 Operational Rail Network Database Combines Inland, Coastal, Great Lakes & Trans-Oceanic Links

7 O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY North American/Trans-Oceanic Multimodal Freight Network

8 O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY An Intermodal Terminal Representation

9 O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY Route cost = modal line-haul travel costs + intra-terminal transfer costs + inter-carrier (interlining) costs + truck drayage costs Railroad #1 Railroad #2 origin destination interline transfer terminal rail line haul truck dray direction of travel cost = function (freight rate + transit time) Example of costs associated with a truck- rail intermodal movement

10 O AK R IDGE N ATIONAL L ABORATORY U. S. D EPARTMENT OF E NERGY 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?)
