Abstract
This paper formulates a departure time choice model based on a time allocation model and analyzes it with empirical data. Data on urban rail commuters are used for empirical analysis. The model assumes continuous time choice in which an individual maximizes his/her utility under the constraints of time and monetary budgets. As our model explicitly incorporates the utilities stemming from sleeping hours and in-home or out-of-home leisure, the individuals preference of these activities can be analyzed directly. For example, the results of empirical analysis show that married individuals obtain higher marginal utility from sleeping time. Additionally, our survey included the SP survey about the dynamic fare system. The results of empirical analysis show that the fare level at the arrival time or at the time of starting work influence the individuals marginal utility with respect to the schedule delay of arrival, starting work, and sleeping.
