This British Standard is an adoption of an ISO standard. You can access the ISO version here.
Intelligent transport systems are revolutionizing the way we travel and commute. A series of standards are in place to support intelligent transport systems. ISO 21219 is a series that discusses standards for traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2). TPEG2 comprises many parts that cover introduction, rules, toolkit and application components. TPEG2 is built around UML modelling and has a core of rules that contain the modelling strategy covered in ISO 21219‑2, ISO 21219‑3 and ISO 21219‑4 and the conversion to two current physical formats: binary and XML.
ISO 21219-6 specifies the stucture of the Message Management Container (MMC) which is used by all TPEG applications to provide information about the handling of messages on the TPEG client side.
The MMC holds administrative information allowing a decoder to handle the message appropriately. This information is not aimed at the end user. The MMC is a toolkit and not a stand-alone application but is included by TPEG applications.
ISO 21219-6 on TPEG2-MMC for traffic and travel information is useful for:
TPEG technology, its applications and service features are designed to enable travel-related messages to be coded, decoded, filtered, and understood by humans and by agent systems. Hierarchically structured TPEG messages from service providers to end-users were designed to transfer information from the service provider database to an end-user’s equipment.
ISO 21219-6 is based on the Traveller Information Services Association (TISA) specifications. TISA set about the development of a new TPEG structure that would be UML-based. This has subsequently become known as TPEG Generation 2. TPEG2 provides an innovative approach and is able to support many new features, such as dealing with applications having both long-term, unchanging content and highly dynamic content, such as parking information.
Message Management Container concept in ISO 21219-6, is applied to the grouping of all message elements including message management information of a TPEG-Message together in one place. The message management container (MMC) toolkit includes two basic mechanisms for message management such as monolithic message management and multipart message management, which are described in ISO 21219-6. ISO 21219-6 guidelines allow you to provide users with relevant messages based on long-term as well as dynamic data.
