The Australian Bureau of Statistics (ABS) has produced the Survey of Motor Vehicle Use (SMVU) since the early 1970s. It has been the principal source of our understanding of the growth in the freight task over the years. However, there have been two major periods of methodological adjustment that complicate the use of the data in computing growth rates in road freight (one in 1998 and one in 2001). The Bureau of Transport and Regional Economics (BTRE) has recently completed an exercise in adjusting past SMVU freight data to make it comparable to the current survey methodology. This paper details these adjustments, and then uses the ‘cleaned‘ data to look at the implied growth rates for road freight into the future.
