The problem-solution-oriented method, capable of evaluating various measures reflecting future social needs and diversified values, will be the mainstream of the next generation transportation demand forecasting method. The activity-based researches have been explored from the viewpoint of. such problem solution. Of particular concerns in this paper are time use patterns involving non-workdays activity and travel behaviors. Using the activity diary survey conducted as a supplementary survey of the fourth person trip survey in Kei-Han-Shin metropolitan areas, a model of time allocation in a non-workday. which the time duration for each of eight types of activity is estimated subject to a time budget constraint, was developed. The proposed model was also examined concerning its validity as a transport-policy evaluation tool.
