BS PD CEN ISO/TS 17425:2016 specifies the In-Vehicle Signage service and application that delivers In-Vehicle Signage information to ITS stations (vehicle ITS stations or personal ITS stations devices)concerning road and traffic conditions, qualified by road authorities/operators, in a consistent waywith road authority's/operator's requirements, in the manner that is coherent with the informationthat would be displayed on a road sign or variable message sign (VMS).
NOTE A Variable Message Sign is also named dynamic message sign. Both terms are considered assynonyms and can be used interchangeably. In the text below, only variable message sign and its abbreviatedterm VMS are used.This Technical Specification defines the following:
- the In-Vehicle Signage service and the In-Vehicle Signage application that instantiates this ITSservice;
- the requirements to be fulfilled by the In-Vehicle Signage service;
- the requirements for using functions provided by the ITS station facilities layer supporting the useof the In-Vehicle Signage service;
- the ITS-S application processes in the different ITS station, that instantiate the In-Vehicle SignageITS service.
This Technical Specification also specifies: the sets of communication requirements and objectives(profiles) using the methods defined in ISO/TS 17423 to select the level of performance (best effort orreal-time, etc.), confidence and security (authentication, encryption, etc.) for each communication flowbetween ITS stations in the scope of the In-Vehicle Signage service.This Technical Specification defines the selection of relevant functions and procedures provided by theITS station facilities layer (ISO/TS 17429) and defines the message structure, content, syntax, atomicelements to be used by the In-Vehicle Signage application.
NOTE This application is colloquially called "In-Vehicle Signage".The In-Vehicle Signage service includes the on-board information management. This managementensures contextual coherence of the end-user ITS service (e.g. vehicle characteristics, message priority,etc. avoiding amongst others things the presentation of conflicting information to end-users).The production of information supporting the In-Vehicle Signage application, its qualification, and itsrelevance are out of the scope of this Technical Specification.This Technical Specification does not specify the design of in-vehicle Human Machine Interfaces (HMI), but it does specify requirements that such interfaces shall be capable of supporting in order to permitthe correct dissemination and use of information provided by the In-Vehicle Signage service.
