It has to be shown, that and how the general model for reference systems and transformations defined in the standard VSS 671941 is practically be applied. This goal can be divided in three parts:

• To analyze and precisely describe practical realizations of the reference system and transformation types given by the general model according the standard VSS 671941 by means of practical data exchange processes and the use of real data. This task has to take into account the data exchange processes between all the concerned systems and organizational units across all levels of the traffic management, e.g., if automatically recorded traffic events in reference system X have to be distributed by radio and therefore need to be transformed in a reference system Y. To achieve this, transformations between reference systems have to be analyzed for data according to the standards (like GDF, Alert C, TPEG,...) of significant applications of intelligent transportation systems (ITS). With this step, the interoperability of reference systems will be demonstrated, i.e. in practice as well there exist transformations between reference systems of linear (like RBBS) , planar (like Swiss coordinates) and topological type (like TMC, RADEF).
• To explain the possibilities and limitations of model-driven approach for the automation of coordinate transformations between different spatial reference systems and topology systems. In this step, the adequate algorithms for the semantic transformation should be integrated.
• To link this research with the international standards (ISO 14,825 GDF ISO 19111 Coordinate reference system, ISO 19,148 Linear Reference Systems, ISO 17572 1,2,3 ITS location referencing according VSS 671941)

Furthermore the project is aimed to propose the basics for the future standards 671941-1 and 671941-2.
