ISO TC204 WG3 and ISO TC204 WG18 DT3 agreed on a joint approach towards development of a globally applicable C-ITS data dictionary containing data types that describe real issues of which instantiations are valid at a given location and at a given time.
This is the first attempt for harmonizing legacy data definitions with new C-ITS data definitions as needed in the Local Dynamic Map (EN ISO 18750), and in the publish-subscribe mechanism (CEN ISO 17429)..
