Time is an important aspect of the activity patterns of individuals. An activity pattern can be described by means of a time-space diagram (H~igerstrand, 1970), that describes, for each moment within a given time interval, the location and type of activity of an individual. These time-space patterns are the result of various decisions and events experienced by that individual. In this paper, we will focus on the time dimensions of the space-time activity patterns of individuals. More specifically, we will focus attention on the allocation of time to a number of out-of-home activities. Other aspects, such as the timing and scheduling of activities are outside the scope of this paper
