C-ITS SIM as a tool for V2X communication and its validity assessment

Nowadays, when new technologies are being developed and people are looking for smart solutions, the field of automation and digitization grows faster and faster. The demand on the telecommunications is increasing in economy, healthcare as well as in the transportation. The transportation systems are facing the challenge of smart infrastructure, autonomous vehicles, and its connectivity. The requirements for these systems lie mainly in safety, interoperability and sustainability, especially in the area of cooperative transport systems (C-ITS).This article focuses on a possible approach to test and evaluate C-ITS, threats that have to be ruled out in future, possibilities to ensure connectivity among the vehicles and infrastructure in C-ITS.For these purposes, Czech Technical University in Prague (CTU) and its laboratory Certilab develop special procedures based mainly on the C-ITS SIM tool. This tool ensures validation and verification of C-ITS messages and its interoperability among all equipment. This paper also reviews the already developed applications and proposal of the functionalities that should be implemented for the testing as well as the examples of real usage of the developed tool in testing the communication of C-ITS messages.
