Transport costs seen through the lens of residential self-selection and mobility biographies

This position paper places transport costs in a longitudinal, life-course oriented perspective. It argues that travel behaviour and the choice of residence may be considered two intertwined decision frameworks made by individuals/households that in turn can be understood within the broader context of mobility biographies. The interrelations between mobility biographies and transport costs are on multiple levels. Firstly, they refer to different types of cost, including user costs, costs for transport provision and external costs. Secondly, mobility biographies and, specifically, residential self-selection may be affected by transport (user) costs, while at the same time they work as input factors for transport costs on all cost levels. The paper outlines these thoughts and discusses the consequences for spatial planning and transport planning. It suggests a strong planning system in which guidelines for travel and residential choice are set by public planning organisations rather than by the market. This is likely to help spare future households increasing transport costs, and costs for transport provision and external costs will be reduced as well. Further, it argues for a shift away from the happiness debate and towards the notion of dignity in transport studies.
