The directional development of intermodal freight corridors in relation to inland terminals

This paper examines the spatial development of freight infrastructure, developing a conceptual model that draws attention to the directional development of intermodal corridors in relation to inland terminals. Two concepts of vertical control of the development process are proposed in this paper, beginning with Inside-Out, whereby inland intermodal terminals seek greater integration with their sea ports, often driven by public body intervention. By contrast, Outside-In development is displayed by the conscious use of an inland node as a tool for sea port actors (whether port authorities or terminal operators) to expand their hinterland and capture discretionary cargo.One of the key distinctions between the two models is the role played by different government approaches to the development of inland terminal facilities. Therefore three national examples are discussed: Sweden, where the public sector is directly involved in development; Scotland, where the private sector is left to develop terminals but government encourages the process through spatial planning and modal shift funding; and the USA, where the national government has traditionally taken little action.The primary contribution of this paper is the research agenda developed out of the conceptual model above, which should be applied to additional case studies in future work. Arising from the conceptual model and the examination of the role of public bodies is a debate on the role of regulation. However the subject of regulation is only touched upon in this paper, therefore more research is required on the government’s role in infrastructure planning and regulation in order to determine the best approach in this policy area
