Mode choice modelling and prediction: the Tasman Bridge case study

Considerable research effort in the transport field over the past decade has been directed towards the development of planning techniques which more accurately reflect the travel behaviour of individuals. A range of behavioural travel choice modes (ie, trip generation, car ownership, destination choice, mode choice) have been developed. However, the application of behavioural models in Australia has been limited and, consequently, there is little local operational experience with these techniques. One recent application has been associated with the tasman bridge, Hobart, Tasmania. The collapse (1975) and reopening (1977) of the bridge necessitated an assessment of the likely impact on transport mode usage, particularly for peak period travel and travel choice models were developed to assist in the prediction of mode/ route changes. This report documents the experience of developing, applying and validating the mode/ route choice models and cities issues of general relevance to the use of travel choice analysis techniques in Australia.
