CEN ISO/TS 19321:2015

This TS specifies the In-Vehicle Information (IVI) data structures that are required
by different ITS services (e.g. In-vehicle Signage such as Contextual Speed, Road
Works Warning, Vehicle restrictions, lane restrictions, Road Hazard Warning, Rerouting)
to transmit information between ITS Stations (I2V).
The information will be specified in terms such as content / data elements and
data structures.
A general data structure that is future proof and extensible will be specified. A
split into sub-structures will be done.
The data structures are to be specified as communications agnostic. The TS needs
to identify groups of potential communication services (e.g. broadcast) such as
existing delivery mechanisms used by e.g. TPEG, DATEX II.
This Technical Specification will not provide the communication protocols.
