This paper describes a methodology for the analysis of multiday travel-activity patterns in which each multiday travel-activity pattern is characterized as a set of daily travel-activity pattern types. This approach facilitates identification of general weekly travel-activity pattern types as well as examination of the relationships between weekly travel-activity behavior and the hypothesized determinants of that behavior. This methodology is an extension of one developed previously by the author for analysis of daily travel-activity patterns. The methodology is applied to a sample of 112 weekly travel-activity patterns of employed people. The paper develops and examines a number of hypotheses concerning weekly and daily travel-activity patterns and their determinants. The empirical results show that general classes of weekly travel-activity behavior can be identified and that these classes of behavior are related to particular individual and household sociodemographic characteristics. The results also show that, for employed people, daily travel-activity pattern type selection is independent of the day-of-the-week, although there appear to be some specific day-of-week differences in the data used in this research. Further, the empirical results do not reject the hypothesis that the selection of daily travel-activity behavior in a two-stage process (selection of weekly behavior followed by conditional selection of daily behavior), is not influenced by socio-demographic characteristics beyond their impact on selection of the weekly pattern type.
