ITS Canada's Architecture and Standards Committee

  • U.S. Department of Transportation (US DOT)

  • ITS Standards Program

    ITS standards are industry-consensus standards that define how system components operate within a consistent framework, which is the National ITS Architecture. The program is working toward the widespread use of standards to encourage the interoperability of ITS systems.

  • Traffic Management Data Dictionary (TMDD)

    The Traffic Management Data Dictionary and Message Sets for External Traffic Management Center Communications Standards work together to provide a high level of interoperability among regional and local systems/centers, providing consistent names, definitions, and concepts similar to spelling and parts of speech to the word-like ãdata elementsä. The TMDD enables concepts from traffic management to be defined and used in the same way by different systems and centers, while also providing for the use of locally unique data elements to recognize the individuality of each system or center.
    • ICDN – ITS Cooperative Deployment Network
    • International Telecommunications Union – ITU
    • NTCIP – National Transportation Communications for ITS Protocol

      NTCIP is a joint standardization project of AASHTO, ITE and NEMA, with funding from the FHWA. Those new to the NTCIP should download The NTCIP Guide, which describes the protocol family and helps with implementing compliant devices.



    • ISO – International Organization for Standardization

      A network of national standards institutes working in partnership with international organizations, governments, industry, business and consumer representatives to provide a bridge between public and private sectors.
