Activity schedules are based on what kinds of activities are persued and how much time is spent for them within the given time. For trip purpose to meet individual's needs, his activity schedule and travel behavior depend on the significant elements such as the kind of activities pursued and the amount of time spent for them. The study examines relationship between social-economic characteristics and weekend travel behavior, and analyzes the factors affecting on activity duration time under the concept of activity-based analysis. Hazard rate models are applied for analysis on activity duration times. Not for simple activity time, duration time considering the sequence of activities is studied by the competing risk model, indicating that the choice and time of current activities depend on the nature and duration of the activities performed previously. The study shows the potential that the competing risk model is one of methods for activity-based analysis, which can inquire into characteristics of individual's activity duration and timing sequence. Also, the study allows to assess the assumed effects of socio-demographic variables on the timing and choice of activities. In future, methodologies for predicting the impact of individual attributes on daily activity-pattern and for analyzing sensitivity on activity transition should be developed.
