The current project studies transport mode choice using a multidisciplinary approach by combining a theory from social psychology (Theory of Material Possession) and a theory from urban planning (Urban structure and transport interaction). Fuzzy set theory and more specifically, fuzzy set qualitative analysis, is used as the analytical method of the project.

The sample consists of commuting students and academic staff in, mainly, four universities of Athens. The analysis was split into two main themes. The first studied transport mode choice through the agent while the second through urban structure. For the latter, the analysis was further split into two groups: the effects of residential location and the effects of workplace location. Throughout the analysis students and workers formed two separate groups.

The results indicate that there is a strong relation between instrumental reasoning and transport mode choice. From the perspective of urban structure, it was found that it has a strong influence on almost all modes of transport. Several typologies of urban structure were identifies which contribute to the use of different modes. These are often mutually exclusive. For instance car use is cause by not low density, medium distances to centre and long distances to rail while public transport use by high density, medium distance to the centre and not long distance to rail.
