3 / 19 Background populations of western world are aging by 2030 almost every third European will be 60 years or older (United Nations, 2007) affects almost every aspect of our lives incl. transport sector today mobility rates and car use of the elderly are smaller than the ones of younger individuals but mobility rates and private car use of older people expected to increase due to lifestyle changes and growing car availability decreasing number of captive riders of public transport negative environmental and safety implications e.g. Rosenbloom (2001).

4 / 19 Consequences measures required that offer more environmentally- friendly alternatives to the private car, still meeting mobility and accessibility needs mobility needs and requirements of the elderly have been research in the last years (e.g. EU projects MOBILATE, SIZE) but most results refer to the whole group of the elderly however seniors are a heterogeneous group with differentiating life styles, needs and requirements 1 need for a more differentiated approach 1 BASt & DVR (2000).

Segmentation approaches of the elderly Käser, 2004Hildebrandt, 2003Kirchmair, 2005Jansen et al., 2001 Segmen- tation according to: variety and frequency of activities socio- demographic and household variables (e.g. age, driving license) life-style variables (e.g. consumer behaviour, leisure time activities) life-style variables (leisure time activities, TV programme, furnishing) Groups / Types Group I (17,7%): low variety and frequency Group II (50,0%): medium variety, small-high frequency Group III (30,5%): high variety, medium- high frequency Group IV (0,5%): low variety, high frequency Workers (11%) Mobile widows (29%) Granny flats (4%) Mobility impaired (12%) Affluent males (39%) Disabled drivers (5%) Demanding consumption- oriented (22%) Conservative wollowers (15%) Expense-oriented innovators (11%) Economical solitaries (11%) Risk-avers traditionals (19%) Sensation- seeking Actives (22%) Indifferent Type (34%) Sensation- seeking Type (19%) Intellectual Type (18%) Refusing Type (15%) Calm life style type (14%) 5 / 19

6 / 19 Evaluation of different approaches different kind of segmentation approaches have specific pros and cons and are relevant for different fields of application 1 not applied for the group of seniors until now: segmentation approach that regards mobility-related attitudes advantages 1 : higher relation to mobility behaviour than life styles and socio-demographic types offer better starting points for interventions than behaviour based and socio-demographic approaches 1 Hunecke, Haustein, Böhler, & Grischkat (in press).

Conclusions Mobility management for the elderly has to recognise the heterogeneous requirements and attitudes of this group. The presented approach defines relevant subgroups, which can serve as target groups for specific measures. Segments mobility behaviour cannot be explained by socio- demographic and infrastructural differences alone but also requires the consideration of mobility-related attitudes. Car availability is not necessarily required for a high amount of leisure time mobility if access to PT is available: three segments with the highest amount of leisure time activities show above average shares of eco-friendly modes (foot, bike, or public transport); none of them uses the car above-average good public transport service can help to enhance mobility of older people and contribute to a high quality of life 18 / 19
