What is ISO 21219-2 - TPEG2-UMR about?
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 21219-2 specifies rules for the creation and extending of Transport Protocol Experts Group (TPEG) application UML models. The rules are intended to ensure that TPEG application UML (Unified Modelling Language) models can be interpreted unambiguously for conversion to physical format representations.
TPEG application UML models that are defined according to these rules can be used for automatic generation of TPEG standards and for automatic generation of TPEG application physical format descriptions.
ISO 21219-2 also specifies the preferred structure of TPEG application specifications. The TPEG abstract data types and the set of TPEG tables of common use are specified in this document.
Who is ISO 21219-2 - TPEG2-UMR for?
ISO 21219-2 on transport protocol experts group, generation 2 UML modelling rules for traffic and travel information (TPEG2-UMR) is useful for:
- IT firms / software engineers involved in TTI programming
- Traffic and safety management systems
- Intelligent transport implementers and installers
- Broadcast management industries
- Transport authorities
Why should you use ISO 21219-2 - TPEG2-UMR?
Seamless communication between systems across varied platforms facilitates intelligent transport systems. 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 21219-2 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 innovative approach and being 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. ISO 21219-2 provides you with design principles that that need to adhere to when building and upgrading TPEG applications. Correct designs permit applications to be upgraded and extended over time, providing new features to new decoders, and yet permit existing decoders to continue to operate.
ISO 21219-2 introduces you to rules for creating TPEG specification documents using TPEG compliant UML models. ISO 21219-2 guidelines help commuters and travellers access transport information that makes commuting more convenient. This is a step towards increasing the overall efficiency of communities, from a larger perspective.
