PROJECTING THE DEMAND FOR OHIO RIVER BASIN WATERWAY TRAFFIC BY CORRELATION AND REGRESSION

The techniques used in projecting future commodity movements on the waterways of the Ohio River Basin and the manner in which these projections were assigned to the navigation projects in the region are presented. Historical data on commodity movements were collected and computer coded. Economic factors and associated projections that have some possible relation to commodity movements were selected, and a set of projected values was obtained for each commodity group by use of simple and multiple regression techniques. Recent trends in port-to-port commodity movements in conjunction with commodity group projections were then used to construct future origin-destination matrices for each commodity group. Finally, by using a traffic assignment program originally developed for urban transportation system modeling, a set of direction-specific and commodity-group-specific tonnages was assigned to each navigation project in the Ohio River Basin. /Author/
