Enabling journeys from door-to-door is an essential part of attracting people towards public transport and away from the private car. Facilitating such journeys requires comprehensive and integrated planning across modal and spatial boundaries. Public transport governance, however, is often constrained by fragmented, multi-level structures and regulatory barriers that limit the ability of responsible organisations to provide a seamless user experience. Sharing experiences between cities in different countries can accelerate learning processes and facilitate the development of more effective organisational structures and regulatory frameworks. The aim of this paper is to analyse how organisation and regulation can support (or hinder) door-to-door mobility. This is done by mapping the roles, responsibilities and relationships between actors who coordinate and collaborate on the design of public transport networks and tariff systems in the context of multimodal networks in Malmö/Lund in Sweden, Copenhagen in Denmark, Berlin in Germany and Trondheim in Norway. Information is gathered through stakeholder workshops in each country. Key regulatory and organisational challenges are identified and national differences between cases are discussed. Examples of structures and mechanisms that support multimodal integration and coordination in each country are also provided.
