This paper describes research to explore the habitual and repetitive patterns of travel behaviour for improving travel demand modelling. The data used in this research are from two Australian panels from which GPS data were collected. The trips recorded by the GPS were initially classified into tours. A tour classification was then applied that grouped the tours into one of twelve tour types and the number of repetitions of each tour type within the time period of data collection were then determined. Having determined how often a particular tour type was repeated over a week or longer, the tours were then described in terms of certain tour characteristics as the initial means to search for identical patterns of travel from one day to the next. To determine if a particular tour type was repeated more or less identically on more than one occasion, the tour type repetitions were described by a coefficient of variation for each of tour travel time, tour distance, tour activity time, and total duration (time) of the tour. From this it was determined that there is relatively little repetition of tours from one day to the next, raising serious questions about the assumptions of repetitiveness that underlie almost all travel demand models.
