This International Standard describes the communications reference architecture of nodes called “ITSstation units” designed for deployment in intelligent transport systems (ITS) communication networks.The ITS station reference architecture is described in an abstract way. While this International Standarddescribes a number of ITS station elements, whether or not a particular element is implemented in anITS station unit depends on the specific communication requirements of the implementation.This International Standard also describes the various communication modes for peer-to-peercommunications over various networks between ITS communication nodes. These nodes may be ITSstation units as described in this International Standard or any other reachable nodes.This International standard specifies the minimum set of normative requirements for a physicalinstantiation of the ITS station based on the principles of a bounded secured managed domain
