This paper reports the application of a traffic light assistant service based on cooperative ITS (C-ITS) standards in European cities. The service delivers Green Light Optimal Speed Advisory (GLOSA) and a time to green service to Audi drivers. the functional possibilities will be shown using this data in a modern connected car. This pre-series deployment comprises several hundreds of intersections in Verona, Berlin, and Garmisch-Partenkirchen. This implementation is the next step in a development line starting with R&D projects involving traffic signal control such as travolution-ingolstadt.de [2] and finalizing in a potential series product service. Applying SAE J2735 [1] Signal Phase and Timing (SPAT) and Map Data (MAP) messages in a real operational environment proved the feasibility of the chosen processing architecture and revealed technical and operational challenges to be mastered. The paper also explains why in this pre-series deployment transition the service is using C-ITS technology, but not DSRC as carrier medium due to commercial and organizational constraints of the operational setting. Furthermore it depicts the requirements of the communication from the automotive view.
