Full title and description

Intelligent transport systems — Traffic and travel information (TTI) via Transport Protocol Experts Group, generation 2 (TPEG2) — Part 22: OpenLR location referencing (TPEG2-OLR). This technical specification defines the logical data format and toolkit structure for OpenLR™ location references to be carried in the TPEG2 location referencing container (TPEG-LRC), enabling map-independent location referencing for traffic and travel information exchange.

Abstract

ISO/TS 21219-22:2017 specifies the logical data format of OpenLR location references, general requirements for the method, and the structure of the TPEG toolkit for OpenLR location referencing (OLR). It describes supported location types (linear, point, area), building blocks of the logical format, data format rules, physical coordinate representations and optional additional data for robust transmission of location information from centres to receivers such as in-vehicle systems and mobile devices.

Scope

This technical specification defines the OpenLR logical location reference format and the corresponding TPEG2 toolkit (TPEG2-OLR) intended for embedding OpenLR references into TPEG2 service data. It covers supported location types (linear, point, area), requirements for maps and location generation, the logical data format and building blocks, rules for data formatting, and physical representations of geo-coordinates used for traffic and travel information exchange. The toolkit is designed to support dynamic, map-independent transfer of location information between a sending centre and receiving devices.

Key topics and requirements

• Definition of OpenLR logical data format and its building blocks (location reference point, path data, offsets, etc.).
• Supported location types: linear (routes), point (POIs or specific locations) and area locations.
• Rules and constraints for generating map-independent location references and their physical coordinate representations (absolute and relative).
• Toolkit structure and integration into the TPEG2 location referencing container (TPEG-LRC) for transport of location references in TTI messages.
• Requirements for map data quality and additional optional data to improve decode robustness on receiver side.

Typical use and users

Implementers of traffic and travel information systems, TPEG service providers, map and navigation vendors, OEMs building in-vehicle information systems, telematics providers and application developers who need to encode and transmit location references in a map-independent way. Typical uses include broadcasting traffic events, travel alerts, route-based information and location-specific services to in-vehicle units, mobile apps and third‑party receivers.

Related standards

ISO/TS 21219-22:2017 is part of the TPEG2 (ISO/TS 21219) family of specifications. Related parts include ISO/TS 21219-1 (introduction and numbering/versions), ISO/TS 21219-7 (location referencing container, TPEG2-LRC), ISO/TS 21219-23 (roads and multimodal routes) and ISO/TS 21219-24 (light encryption), among other TPEG and TTI standards; earlier TPEG/TII location referencing work is also found in ISO/TS 18234 series. These documents together define service frameworks, containers and supporting toolkits for TPEG2 traffic and travel information exchange.

FAQ

Q: What is this standard?

A: ISO/TS 21219-22:2017 is a technical specification defining the OpenLR location referencing logical format and the corresponding TPEG2 toolkit (TPEG2-OLR) for embedding OpenLR references into TPEG2 traffic and travel information messages.

Q: What does it cover?

A: It covers the structure and rules for OpenLR logical location references (linear, point and area locations), requirements for map data and location generation, the logical data format building blocks, physical coordinate representations, and the toolkit packaging for use within the TPEG2 location referencing container.

Q: Who typically uses it?

A: Traffic and travel information service providers, TPEG implementers, map and navigation system vendors, telematics and OEM developers — any party that needs to encode and transmit map-independent location references for TTI distribution to receivers such as in-vehicle systems and mobile applications.

Q: Is it current or superseded?

A: The document was published in June 2017 (first edition). According to ISO’s published lifecycle information it was reviewed and confirmed as current (review status) in a subsequent five‑year review.
