This paper presents the findings from a travel behaviour survey that was conducted on a congested commuting corridor in Brisbane. Drivers' responses to travel information from a variety of sources are analysed and presented. The paper also presents a number of discrete-choice models that were formulated to analyse the impacts of socio-economic, context and information variables on individual behaviour and the propensity to change route and adjust travel patterns. The results from these models clearly indicate that en-route prescriptive, predictive and quantitative real-time delay information is most effective in influencing drivers to change their routes. The results reported in this paper provide a useful insight into the factors influencing travel behaviour and route choice along the corridor. Furthermore, the behavioural models describing drivers' route choice decisions will also provide road authorities with a valuable tool to design and evaluate effective traveller information strategies aimed at influencing travel behaviour, reducing congestion and enhancing the performance of the road network.
