Validating a model of short and long-term dynamics of activity-travel behavior: Descriptive analysis results

This paper focuses on the descriptive analyses of stated adaptation data that have been collected to validate a dynamic model of activity-travel behavior. This model aims at predicting the dynamic responses to various exogenous and endogenous changes. Specifically, due to various reasons, it is possible that an individual’s expectations deviate from his/her activity-travel experiences. This discrepancy is defined as stress and can trigger an endogenous, self-improvement process, which may result in short or even long-term adaptations. In this paper, descriptive analyses results will be presented regarding the socio-demographic characteristics, the aspirations and the activity-travel patterns of the respondents. Finally, inertia and the tendency to stick to habitual behavior, as well as the short and the long-term adaptations that they have decided, are examined in detail.
