TRANSPORT FLOWS IN THE STATE OF INDIANA: COMMODITY DATABASE DEVELOPMENT AND TRAFFIC ASSIGNMENT, PHASE 1. FINAL REPORT

Identification of the nature and volume of traffic on Indiana's roads, railroads, and waterways is important in terms of setting priorities for capital investments. This study's goal was the creation of a database that would include the flows of manufactured goods, major grains, and coal along the state's transport networks, which would also be defined in digital form by the study. Transport networks for the highway, railway and waterway sectors were defined for the study using a combination of original and existing digital networks. Nodes were defined for each county of Indiana and for other areas around the United States. Average shipment lengths were derived from existing data sources. Traffic production and attraction data for grains and coal or estimates for manufactured goods, and the average shipment lengths were used in a fully constrained gravity model to generate flows between Indiana's counties, as well as between those counties and the remainder of the United States. A modal split model based on commodity and shipment length was used to separate the traffic into the highway, rail, and waterway modes. An all-or-nothing traffic assignment algorithm was used to assign traffic to the networks. The study indicates that the rail sector's major traffic in the state is east-west and west-east. The highway sector is also important in such flows, but dominates the north-south and south-north commodity flows. For the highway sector, translating the commodity specific bushels and tons into comparable motor carrier equivalents, adding these together, and mapping the same illustrates the dominance of selected highways for the goods examined.
