Reliable v2x communications for safety-critical intelligent transport systems

In the future intelligent transport systems (ITS) the reliability and precision of the cooperative and autonomous vehicles are of the utmost importance. For such systems vehicle-to-vehicle and vehicle-to-infrastructure (V2X) communications is safety-critical component of ITS. Many mobility and convenience applications of ITS require the V2X bidirectional communications mode. This paper focuses on evaluating reliability of bidirectional communication channels with redundant equipment and periodical sessions of communication with test during communication sessions and with additional periodical test in the pauses between communication sessions. The optimal periodicity of channel monitoring is defined.
