1 INTERMODAL FREIGHT TRANSFER FACILITY DATABASE

2 INTERMODAL SURFACE TRANSPORTATION EFFICIENCY ACT (ISTEA) OF 1991 Commitment to a National Intermodal Transportation System that links every point to all the other points People and goods can move at reasonable speed and economical cost Effective connections and coordination between and among modes are important and frequently the weakest links in the Nation s s Transportation s s Systems System productivity and gains can be achieved by improving intermodal connections

3 1998 ORNL DATABASE Flat file Customers and Facilities are treated the same Rail is the primary modal coverage, no Air data included No contact information provided Approximate lat longs for Facilities (refer to metadata) Maximum of two modes per record No differentiation of commodities & cargo Does not support multiple commodities, cargo & directionality associations Commodity is not always included

4 PROJECT OBJECTIVES To develop an intermodal freight transfer facility database that: Responds to users needs Is representative of the involved transportation modes Is spatially accurate Can be periodically updated and enhanced

5 DATA SOURCES Web Publications (hardcopy & electronic formats) Government agencies Referrals (metadata) Direct inquiries Current BTS data

6 INTERMODAL FACILITY Criteria used to identify and/or process a facility: Is the focal point for freight transfers Must: be intermodal commodity data include physical address or geographic coordinates

7 DATA PREPARATION & Data scrubbing VALIDATION Removal of duplicates and invalid data Data geocoding High spatial accuracy for facility Spatial QC

8 FACILITY DATABASE Facility Commodities Shipment Type Dir.

9 COMMODITY TYPE Code Description of Commodity 1 Live Animals And Fish 2 Cereal Grains 3 Other Crops 4 Animal Feed, Pet Food, And Products Of Animal Origin 5 Meat, Fish, And Preparations 6 Milled Grain Products And Preparations And Bakery Products 7 Other Prepared Food Stuffs 8 Alcoholic Beverages 9 Tobacco And Manufactured Tobacco Substitutes 10 Monumental Or Building Stone

10 SHIPMENT TYPE Code Description of Shipment Types 100 General cargo "anything other than bulk" 110 Manufactured 120 Semi-manufactured 130 Package goods 200 Breakbulk cargo 210 Food and kindred products 220 Lumber and logs in the rough 230 Metal products -- primary and finished 240 Machinery 250 Motorized and other vehicles, including parts

11 COMPARISON 2002 Relational database Differentiation of Customers and Facilities Representative of several transportation modes: Rail, Ports, Trucks & Air Easily validated -Contact information provided Accurate lat longs for Facilities (12-40m) provided by geocoding with detailed street data Support more than 2 mode per facility & customer Differentiation of commodities and cargo Commodity information is required Multiple commodities (required), cargo & directionality associations 1998 Flat file Customers and Facilities are treated the same Rail is the primary modal coverage, no Air data included No contact information provided Approximate lat longs for Facilities (refer to metadata) Two modes per record No differentiation of commodities & cargo Commodity is not always included Does not support multiple commodities, cargo & directionality associations

23 FUTURE DIRECTIONS Potential new phases: Expand on motor carriers and trucks Intramodal facilities from previously processed sources Transportation networks and intermodal facilities
