Overview
CEN ISO/TS 18234-11:2013 - TPEG1 Location Referencing Container (TPEG1-LRC) specifies how location referencing is signalled within TPEG1 (Traffic and Travel Information) binary messages. It establishes the method for indicating which specific location referencing method is used by TPEG1 applications that require detailed location information (for example TPEG1-RTM, TPEG1-PTI, TPEG1-TEC, TPEG1-PKI). The Technical Specification describes the TPEG1-LRC structure and how it can reference both internal methods (e.g., TPEG1-LOC defined in Part 6) and external location referencing schemes.
Keywords: TPEG1-LRC, ISO/TS 18234-11:2013, location referencing, TPEG, TTI, intelligent transport systems.
Key Topics
- Signalling location methods: Defines how a TPEG Message indicates which location referencing scheme is in use (dynamic or pre-coded references).
- Location Referencing Container (LRC): The container format that encapsulates the selected location referencing method and payload for use by TPEG applications.
- Supported methods: Document lists and structures for multiple methods (examples included in the specification): DLR1, Korean Node‑Link, TMC, TPEG Location, VICS Link, ETL, GLR.
- Message components: Defines generic component IDs and specific reference types such as TPEGLocationReference, DLR1LocationReference, TMCLocationReference, KoreanNodeLinkLocationReference, etc.
- Binary coding and SSF: Annex A defines binary Syntax, Semantics and Framing (SSF) data types used by the container; the standard uses the byte‑oriented TPEG data stream model.
- Interoperability focus: Enables services and client devices to parse and resolve location details consistently across different TPEG1 applications and bearers.
Applications
- Navigation systems & in‑vehicle infotainment: Deliver precise event locations to routing engines and map displays.
- Traffic information broadcasters & service providers: Encode and transmit road events and travel information using standardized location references.
- Telematics & fleet management: Integrate TTI data into fleet tracking and route optimization workflows.
- Map vendors & location data integrators: Map external location referencing methods into internal GIS representations.
- Traffic control centres and ITS integrators: Use TPEG1-LRC to ensure client devices and downstream applications interpret reported locations reliably.
Who uses it: ITS engineers, TPEG implementers, telematics providers, automotive OEMs, digital radio/television broadcasters, and navigation/mapping vendors.
Related Standards
- ISO/TS 18234‑1..10 (TPEG1 series) - especially:
- Part 2: Syntax, Semantics and Framing (TPEG1‑SSF)
- Part 4: Road Traffic Message (TPEG1‑RTM)
- Part 5: Public Transport Information (TPEG1‑PTI)
- Part 6: Location referencing applications (TPEG1‑LOC)
- Part 9: Traffic Event Compact (TPEG1‑TEC)
This specification is essential when implementing interoperable TPEG1 traffic and travel information services that require precise, standardized location referencing for client devices and navigation systems.
