Analysis of commuters' responses to travel information: Implications for ATIS deployment in Brisbane

The provision of real-time travel information is recognised as a potential strategy for influencing traveller behaviour on trip mak-ing, route and mode choices and times of travel. Understanding travellers' response to this information is therefore critical to the design and implementation of effective ITS strategies such as mobile or fixed advanced traveller information systems (ATIS). This paper presents some initial results from a travel behaviour survey that was conducted on a congested commuting corridor in Bris-bane. Commuters' responses to travel information from a variety of sources are analysed and presented. A number of probit models being 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 are also presented. The results obtained from this study provide a useful insight into the factors influencing travel behaviour, route choice and departure time decisions. These results also provide a much needed database that can be used for current research projects on modelling dynamic driver behaviour and evaluating the impacts of traveller information systems. These models will provide road authorities with a valuable tool to design and evaluate effective ATIS strategies aimed at influencing travel behaviour, reducing congestion and enhancing the performance of the road network
