In the research project simTD (Safe Intelligent Mobility – test area Germany) the car-to-x communication (i.e. the communication between vehicles among each other and the communication between vehicles and infrastructure) is implemented and tested, and the benefit for a safer mobility is demonstrated via different applications. The project started in September 2008 and is scheduled to take four years.
Essential aims of the project are:
- an increase of traffic safety and an improvement of the potential of the traffic networks through the application of car-to-x communication
- the validation of the individual functionalities based on car-to-x communication
- the definition and test of validation metrics for new technologies
The project requires a wide range of technical equipment: short range and cellular radio communication of accordingly equipped vehicles, intelligent outstations with radio interfaces, and a new test centre, where all the data is collected, are set up.
On behalf of the Hessian regional road construction authority the Heusch/Boesefeldt GmbH develops the software for the test centre in Rödelheim. The approach taken is a combination of the service-oriented architecture via ESB (Enterprise Service Bus) with a data-centred architecture via data distributor and a relational data base.
In the project, Heusch/Boesefeldt uses the Open-Source-Product FUSE ESB which, apart from other standards, also supports OSGi. As the basic data service the Heusch/Boesefeldt product GeoDyn2®, using the open source data base management system PostgreSQL, is applied.
In addition, the use of GeoDyn2® also allows the realisation of a hot standby functionality for the test centre.
The graphical user interface was realised by applying web technologies. A standard web browser utilizing JavaScript acts as client.
In milestone 4 „Subsystems are available“, in which the basic functionalities of the subsystems were to be introduced to the ministries and the bodies running the project, the new test centre was presented on schedule. Here the car-to-car as well as the car-to-infrastructure communication via short range radio communication and cellular radio were demonstrated. The results were evaluated very positively by the reviewers.
