For older persons, everyday mobility is an important aspect of living an independent and self-determined life. Especially with increasing age most of the everyday ways in urban areas are covered by foot. The more severe is the fact that older pedestrians are among the most vulnerable road users. This is the starting point of the research group FANS aiming for developing a pedestrian assistance system for older road users. Therefore, it is necessary to understand the difficulties older pedestrians encounter. In order to do so, everyday mobility of this group will be conceptualized using the Constraints Approach by Hägerstrand and the Theory of Structuration by Giddens. Currently, two focus groups have been carried out that have been analyzed according to Hägerstand's and Gidden's considerations. Hereinafter, the category system that has been derived from the theoretical considerations will be presented and an outlook will be given.
