车辆到车辆（V2 V）和车辆到基础设施（V2 I）通信多年来一直是研究和开发主题。今天，技术进步提供了所需的通信带宽，并允许车载设备的串行生产。该研发项目simTD（安全智能移动-测试场德国）旨在使用100多辆汽车在真实的生活中测试V2X技术。因此，这是第一个进行现场试验的V2X项目，有足够数量的车辆来实现显著的评估结果。现场试验并不是唯一的事情，这使得simTD独一无二：主要项目目标不是测试技术，而是评估真实的环境中的合作应用，包括基础设施，特别是交通中心，以完全集成到这些应用中。因此，还设计和实施了一个新的合作交通中心，需要新的技术方法来科普新的功能和非功能要求，例如从大量移动探头不断流入的信息。本文介绍了在SIMTD的交通中心的一般系统架构所采取的方法。然后，它将重点放在特定的问题领域，如位置引用或协作环境中的软件部署。simTD中的要求导致了一种新的“混合”系统架构，并使得有必要选择一种全新的方法来在交通中心侧进行位置参考。
Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication has been a research and development topic for many years now. Today technological improvements offer the required communication bandwidth and allow serial production of in-car-equipment. The R&D project simTD (safe & intelligent mobility – test field Germany) aims to test V2X technology in real life with more than 100 vehicles. It is thus the first V2X project conducting a field trial with a sufficient number of vehicles to achieve significant evaluation results. The field trial is not the only thing, which made simTD unique: the main project goal is not to test technologies, but to evaluate cooperative applications in real environment including infrastructure and especially the traffic centre to be fully integrated into these applications. Therefore a new cooperative traffic centre was designed and implemented as well, requiring new technical approaches to cope with new functional and non-functional requirements, like information constantly flowing in from a high number of moving probes. This paper presents the approach taken in simTD concerning the general system architecture of the traffic centre. It then focuses on specific problem areas, like location referencing or software deployment in a cooperative environment. Requirements in simTD have led to a new “hybrid” system architecture and made it necessary to choose a completely new approach for location referencing on the traffic centre side.
