The unsustainability of current trends in daily mobility and the need to manage travel demand constitute the background of this article, which focuses on the notions of attitudes and mode choice behavior. In this context, an approach to the study of their mutual relationship is put forward and exemplified by the discussion of an attitude dimension, "social mixing and secessionism in daily mobility", focused on the propensity to share space with strangers during travel. The author then presents the results of an exploratory empirical study, carried out on a sample of college students in Milan in 2010 and aimed at testing the existence and the internal structure of the construct. While the complexity of the attitude dimension will probably require further studies, the results confirm the heuristic potential of the proposed theoretical framework.
