After the Trans-European transport Networks (TEN) process which also involved EU Candidate States with the objective to deliver a European Infrastructure plan, further activities in the field of intermodal goods transport rarely head in this direction. However, the interconnection between Candidate States and Central Europe is still not sufficient, particularly as these regions are essential in connecting the Central European Countries to the Far and Middle East. Partners from former INTERREG projects such as ECO4LOG (INTERREG III C East) realized the high demand for extending the existing intermodal goods networks in Central Europe towards the accession countries of Romania and Bulgaria as well as to other countries. These countries form the gate to the Black Sea region and Greece, also in the sense of spatial development. The further integration of countries sharing borders with the EU is a central challenge for CADSES. Especially, sustainable transport relations are needed in the CADSES area to promote the further integration of a single European market. Interoperability in terms of goods is the backbone of this issue. Expected Results: The INTERIM project demonstrates with selected intermodal transport chains (rail, inland waterway and harbour-hinterland) how this integration process can be implemented with respect to intermodal market and spatial development. Experiences and conclusions from the common work can be generalised and used for implementation in other countries and other integration fields. The following results and effects are expected: - Analyses of the supply and demand side of intermodal services, - Definition of missing services, links, recommendations, - Development of new intermodal concepts and IT instruments to support further integration (intermodal integration platform, intermodal information platform for administrations), - Benchmarking and the elaboration of a multimodal action plan, - Know-how transfer, - Improvement of administrative, economic and transport structures related to spatial planning and development, - Integration of intermodal transport issues into spatial planning and regional development concepts, - Joint use of IT-based planning and information tools which might later be adapted to other countries.
