A meta-theory for travel-related choices

• We propose a multidisciplinary meta -theory for travel and travel-related choices. • Includes motivations, decision-making paradigms. • Includes the type of travel choice, personal characteristics, and context factors. • Helpful for a comprehensive theoretical underpinning of travel behaviour studies. In this paper we propose a meta -theory for travel and travel-related choices (MTTC). The meta -theory envisions that travel choices are based on five building blocks: (1) travel motivations (regarding whether to travel or not in the first place, and regarding the choice of specific alternatives associated with the main decision to travel), (2) the decision-making paradigm , (3) the type of travel choice , (4) personal characteristics , and (5) context factors . After explaining each of these building blocks, the paper offers a conceptual model that links them. It closes with some suggested avenues for future research. The MTTC helps researchers to explicitly underpin their methodological choices. In addition, we conclude that there is much heterogeneity with respect to the combinations of the five building blocks of the MTTC, and allowing for this heterogeneity improves our understanding of travel (-related) choices.
