The article investigates the question, whether and in how far the travel behaviour of the former GDR inhabitants and the former FRG inhabitants has equalled since the years after the German reunification. A person-group specific analysis shows that the major differences still consist only in the elderly of age 60 and above. This is mainly due to the much slower process of motorization within this age group in the former GDR. In the younger age groups the adaption of the travel behaviour has almost been achieved; mainly as a consequence of the fast motorization process since 1990 in these age groups. Where differences are still valid, this stems firstly from worse supply conditions, especially with public transport, but also with road infrastructure, as can be seen by an overall lower system speed in the former GDR. A panel analysis shows, that the dynamics in terms of transport specific life style changes is far more relevant in the former GDR than former FRC. This is linked with higher mobility in the persons with such changes. These changes will probably come to an end once the economic development will have stabilised and the cohort with the biggest behavioural differences will gradually decrease.
