Travel behavior models typically assume that people base their travel choices on time and cost considerations and do not account sufficiently for qualitative factors that affect the choice. Travel choices are however more likely to be motivated by a desire to maintain or enhance travel wellbeing. In addition to time and cost, travelers value factors such as reliability, comfort, convenience, safety, etc. Thus, travel well-being is a broader concept that encompasses generalized cost. While there have been numerous studies that have measured some travel wellbeing in one form or another (happiness, stress, satisfaction, liking), most of these studies have been cross-sectional. Yet, well-being is a dynamic process, and measurements of well-being could produce different answers depending on the moment in time at which it is measured, such as under habitual or non-habitual travel conditions. Our aim is to assess these dynamics in travel well-being and to develop a modeling framework that captures the relationship between wellbeing and travel behavior.
