Transport integration of TERN is a fundamental pre-requisite for SE Europe regional cohesion and development. On the other hand, ITS applications are key tools to support efficient infrastructure management and traveller information on TERN. In order to maximise benefits out of ITS deployment, SEE-ITS aims at stimulating co-operation and interoperability between isolated ITS applications so as mobility is supported seamlessly throughout TERN motorways, secondary and urban/periurban road networks, as well as with their interfaces to other modes, such as surface public transport, ports and inland waterways. SEE-ITS will develop an institutional and technical framework through which SEE organisations and countries can harmonise ITS specifications and define generic collaboration model based on acceptable scenarios. Furthermore, the project will execute focused pilots to assess the scenarios, perform impact analysis, benefit by the ITS industry participation in the project and deliver a Regional Framework, a User Forum and a long term plan for viable future investments.
