An understanding of variability in travel behavior is essential for both analytical and operational processes. Conventional methods rely on interpersonal variability from one-day data. However, it has been found that the intrapersonal variability may constitute a substantial proportion in the total variability. The availability of electronic toll collection (ETC) opens possibilities to collect multiday individual data. This paper uses the multiday ETC data on Tokyo Metropolitan Expressway in 2010- 2011 to examine the interpersonal and intrapersonal variability of the daily travel behavior. This long term data can be used to observe the effects of the day and the month to these two types of variability.
