ISO/TR 14823-2 presents examples of ASN.1 coding of a Graphic Data Dictionary that has been developed with the intent of creating a common basis for transmitting encoded information for existing road traffic signs and pictograms. The coding system has been developed to be language-independent, such that data supports Intelligent Transport System (ITS) applications such as in-vehicle signage or in-vehicle information.
ISO/TR 14823-2 supports the efficient IT-centric encoding for ITS messaging to represent specific road traffic signs and pictograms, and the consistent decoding of encoded road traffic signs and pictogram data for display in ITS.
ISO/TR 14823-2 supports the translation of signs and pictograms with a similar purpose from the representation used in one country to the representation used in another country.
ISO/TR 14823-2 on ITS graphic data dictionary is useful for:
The purpose of graphic data dictionary is, in order to facilitate the data exchange between media, to catalogue graphic images like traffic signs and pictograms specified and used uniquely in each country and to assign them a certain code.
ISO/TR 14823-2 provides you with a system of standardized codes for existing signs and pictograms used to deliver traffic and traveller information (TTI). The coding system can be used to form messages to be handled by respective media systems, graphic messages on on-board units, and media system information on TTI dissemination systems (VMS, PC, PAT, etc.) (including graphic data). ISO/TR 14823-2 presents a graphic data dictionary which has been developed with the intent of creating a common basis for transmitting graphic information data that can be, irrespective of language or regional differences, decoded and understood by the users who obtain TTI service through TTI system operators such as traffic management centres, traffic information centres and value-added service providers which add value to the TTI.
ISO/TR 14823-2 Adopting unified graphic data is expected to improve the understandability of the graphic information by the user and thereby increase the convenience of TTI systems.
