A testing framework for Intelligent Transport Systems

Experimental deployment of Cooperative Intelligent Transportation Systems have been undertaken these last years. But a real deployment is lower than expected. One reason is the lack of complete validation techniques which handle the whole system. The aim of this paper is to present a complete framework able to test each component involved in a C-ITS and which is able to check the interoperability of all components. This framework ensures the conformance testing of all the C-ITS components regarding their specifications (mainly the communication protocols which ensure the interoperability over various layers) as well as the interoperability testing of these components in order to guarantee their correct functioning where they perform together. This framework has been used with mobile ITS stations and fixed ITS stations provided by different vendors. Many test series have been undertaken. C-ITS development is not quite mature, then many bugs have been detected thanks to the execution of test cases. The design of this framework and its use have shown that a deployment of an actual C-ITS is still a difficult task. The use of our framework has underlined that some standard specifications (either protocols or test case specifications) need to be improved.
