There have been previous Bureau of Transport and Regional Economics (BTRE) aggregate estimates and forecasts of interstate freight. A start was made last year on disaggregate road interstate freight estimates with a publication entitled State-to-state origin-destination (OD) time series. This paper adds new disaggregate rail and coastal shipping state-to-state OD pair freight series and derives new OD pair interstate freight forecasts to 2030-31. These estimates are important because capital city to capital city data has dried up, whereas annual interstate freight estimates can be derived from the Survey of motor vehicle use (SMVU) for road, from rail companies for rail, and from the BTRE for coastal shipping.
