The nature of the peak period travel behaviour and the influence of peak spreading policies are a growing concern for transportation planners. Current models are often lacking in their ability to adequately represent trip flexibility with respect to departure time choice for the car-based commute. There is a need to improve forecasting models to better represent the temporal element of travel choice. This is emphasised by the findings of the UK Standing Advisory Committee on Trunk Road Assessment who report that peak spreading is an important behavioural reaction to changes in road capacity, second only to changes in route. This paper outlines research into the development of a departure time change model based on Australian data. It presents the approach and results of an on-line survey and subsequent choice model development as it is applied to a policy-based test scenario.
