In Dutch policy-making, there is a growing emphasis on embracing a broad definition of welfare, transcending traditional economic metrics and encompassing all facets valued for a good life, both presently and for future generations, as well as on a global scale. This perspective, called brede welvaart in Dutch, is referred to as broad prosperity in this research. Despite the widespread belief in the importance of policy integration for fostering considerations of broad prosperity in mobility policy, the governance of this integration remains ambiguous. This thesis aims to address how governance structures can effectively ensure that broad prosperity principles are utilised in mobility policy-making, particularly through integration with urban development policy-making.
Adopting a qualitative multiple-case study approach, this research systematically investigates the intricate interplay between policy integration in mobility and urban development, broad prosperity considerations, and the resulting policy-making process. Literature review and expert interviews are combined to formulate a conceptual framework for distinguishing broad prosperity policy-making from conventional policy-making and measuring policy integration. A thorough analysis of the decision-making process in mobility plans for the cases Zeeburgereiland, Binckhorst, Valkenhorst, and Merwedekanaalzone is executed through document analysis and stakeholder interviews. This information together with results from focus groups in which workable governance approaches are discussed, provide an answer to the main research question: How should the governance of mobility and urban development be organised to enable a broad assessment of welfare in policy-making?...
