Most western countries (such as Belgium) have been witnessing prominent demographic ageing. Ageing often implies declined functional capacities and hence declined capacity for travel. As travel is imperative to live independently and maintain social ties, declined capacity for travel is likely to adversely affect elderly’s wellbeing. “Ageing in place” – without relocation – is a key strategy for coping with the challenges of an ageing society. Resources of living environment are closely associated with an individual’s lifestyle, activity participation and quality of life. In order to secure travel options and enhance the wellbeing of older adults, it is important to understand the relationships between living environment, activity-travel behaviour, and wellbeing. In this project, the question of how physical and social aspects of the living environment affect activity-travel behaviour of older adults will be investigated. Furthermore, the relationships between elderly’s wellbeing and activity-travel behaviour will be explored. Finally, by identifying the key elements of living environment which maximise elderly’s wellbeing in an activity-travel context, policy interventions will be discussed for building an age-friendly society.
