Recent studies show the importance of key events during life course to change individual travel behaviour and thus to implement travel demand measures. This paper aims to better understand the influence of university graduation as a supposed key event on travel mode choice. Furthermore the interest of using an integrated mobility service package during this key event as an alternative to car ownership is examined. Integrated mobility service packages are a combination of a monthly tram ticket, a carsharing-membership, bicycle services, a long-term railway ticket, delivery services, reduced fees on taxi-driving and on car rental in one offered package. The empirical study had three main goals: (i) We analysed if university graduation can indeed be considered a key event for changing mobility behaviour; (ii) which individual and structural characteristics are important to accept integrated mobility services and (ii) which design for an “ideal” integrated mobility service package is needed to be an alternative to car ownership. Four qualitative focusgroups with fifteen graduates of the University of Leipzig were conducted and analysed by qualitative content analysis. The results show that integrated mobility services might be an important tool to influence daily travel mode choices, especially in the examined life passage. Furthermore, five main interrelated individual and structural characteristics could be identified among the interested interviewed persons. In all, four main components build the „ideal“ integrated mobility service package: a monthly tram-ticket, a longterm railway ticket with fifty percent reduction, a carsharing-membership and bicycle services. For the analysed group, integrated mobility service packages can be considered an alternative to car ownership but also to replace a second car in the household.
