Principles of the Formation of Physical and Functional ITS Architectures

The article discusses the requirements for the construction of the physical and functional architecture of intelligent transport systems (ITS), taking into account the experience of the development of equipment and technologies in the field of ITS, cooperative systems and highly automated vehicles. The article reflects the basic principles of building the functional and physical architecture of ITS. When developing ITS architectures, the structure of ITS construction is considered, where the integration platform includes modules of ITS complex subsystems. The architectures should reflect the parts related to information security, as well as ensuring the interaction of ITS with external information systems and the national network of ITS. For a clearer understanding of the structure of ITS in architectures, the level of the information and telecommunications network is considered, which is the link between the instrumental subsystems of ITS and the element base of ITS.
