Occasional Paper 42

From July 1977 to June 1978, the Bureau of Transport Economics (BTE) conducted the National Travel Survey (NTS). This was a major survey of nonurban travel in Australia. This Paper discusses the sources of bias and errors in the NTS data and presents a method of adjusting the statistical results for non-response bias. The general design of the NTS is evaluated in the light of the practical experience gained from its operation. Finally, the Paper presents a range of tabulations summarising some of the more important and interesting results derived from the NTS data. These results have been adjusted for statistical non-response bias and have been calculated to apply to the population.
