What is ISO/TR 14823-2 – ITS graphic data dictionary about?
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.
Who is ISO/TR 14823-2 – ITS graphic data dictionary for?
ISO/TR 14823-2 on ITS graphic data dictionary is useful for:
- Transport authorities
- Traffic management and information centres
- Traffic and traveller information system operators
- Public transport centres
- IT and telecommunication firms
- Tech developers / Software programmers
- Regional Transport Offices
- Transport and safety management industries
- Organizations that manage road transport and highways
Why should you use ISO/TR 14823-2 – ITS graphic data dictionary?
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.
