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.

CONVERGE项目-ITS的系统网络

德国和欧洲的各种研究项目为智能交通系统（ITS）基础设施创建了几个隔离的解决方案。实际上，许多解决方案都是临时的。这些系统提供的后端体系结构主要集中在仅支持基于车辆的应用程序和通信环境下的主题测试和评估。有几个研究项目评估了ITS路边或中央站点与车辆站点之间的不同通信路径。研究社区的当前方法是将多种交流方式结合起来，以提供最大的收益。两种最有前途的技术是蜂窝通信和车对车通信。由于已经有研究项目评估了这些交流路径之一的可能性，因此很少有研究项目评估过这些路径如何相互补充。Car2X Systems Network的结构将基于Internet，其中不同且独立的参与者通过标准化的接口和协议共同努力。但是，Car2X Systems Network需要一些特殊的解决方案，因为Internet的概念并不完全适用于ITS世界的要求。尤其是在当前最新的互联网服务中，ITS环境的严格安全性和隐私考虑并未得到解决或仅仅得到了解决。此外，还需要考虑诸如服务质量之类的网络要求。因此，
