Abstract
The decision process of human travel-activity schedule has been studied with the data obtained by the person-trip survey of Nagoya region in 1981. Since people in urban area behave within the limited time and space, the model is formulated with three stage nested logit model: lower level represents the choice of locations and duration of discretionary activities; and middle and upper level the choice of travel-activity patterns which are classified by number of trips and times of tentative home-return. Three submodels are applied to workers' travel-activity schedules within available time and space each of before and afterward of their work. The calibration caused good results and the measure of goodness-of-fit indicates very high consistency.
