The CONVERGE project – A systems network for ITS
share
Various German and European research projects created several isolated solutions for intelligent transportation systems (ITS) infrastructure. As a matter of fact, a lot of those solutions are temporary. The backend architecture provided by those systems is mostly focused on only supporting test and evaluation of topics in the context of vehicular based application and communication. There have been a couple of research projects, which have evaluated the different communication paths between ITS roadside or central stations and vehicle stations. The current approach of the research community is to combine multiple ways of communication to provide the greatest benefit. Two of the most promising technologies are cellular communication and Car-to-Car communication. As there have already been research projects which evaluate the possibilities of one of those communication paths, few research projects have evaluated how those paths could complement each other. The structure of the Car2X Systems Network will be based on the Internet, in which different and independent participants are working equally together over standardized interfaces and protocols. However, the Car2X Systems Network needs some special solutions, as the concepts of the Internet are not entirely applicable to the requirements of the ITS world. Especially the strict security and privacy considerations of ITS environments are not or only insufficiently addressed in current state-of-the-art internet services. Furthermore, network requirements like Quality of Service needs also to be considered. Thus, the Car2X Systems Network aims to provide open, standardized, secure and interchangeable interfaces for each possible participant of the ITS environment.
