The paper is an attempt to critical discuss of the evolution of transport planning notion in the research literature - including the geographical one. The author presents key points of this discipline and reviews the difficulties associated with qualitative research on mobility - a field usually characterized by rational behavior prompted by external factors and economic factors. The social sciences suggest that mobility results in outcomes driven by social and psychological needs. The author suggests that geography is an important element of the interdisciplinary approach needed to analyze transport behaviors in both qualitative and quantitative terms. Finally, the author discusses space syntax theory and its applicability in research on the effects of geographic space on mobility.
