A test architecture for V-2-X cooperative systems field operational tests

In recent years, several research projects have discovered the potential of Intelligent Transport Systems (ITS) and have developed corresponding demonstrators for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication, which act as proof of concepts. This paper provides the required test infrastructure to go beyond a pure proof of concept by enabling the validation of a complete V2X communication system that covers V2V and V2I communications plus the interconnection of vehicles and backend systems known as Vehicle-to-Business (V2B) communication. We present an integrated test architecture that allows not only the evaluation of vehicular communications on test tracks but moreover paves the way for conducting real life Field Operational Tests (FOT) with thousands of vehicles based on state-of-the-art broadband wireless access technologies. In addition, this paper presents the selection procedure applied for the identification of hardware and software components required for realizing the V2X system based on a predefined set of Use Cases (UCs).
