Full title and description

Intelligent transport systems (ITS) — Location referencing for geographic databases — Part 2: Pre-coded location references (pre-coded profile). This international standard defines a pre-coded Location Referencing Method (LRM) used to represent, encode and exchange pre-coded location references for transport and traffic information systems, including logical and physical format guidance for several traffic messaging protocols.

Abstract

The ISO 17572 series specifies Location Referencing Methods (LRMs) for describing locations within geographic databases for use by encoder and decoder systems in ITS applications. ISO 17572-2:2018 specifies the pre-coded profile: the structure and components of pre-coded location references, which components are mandatory or optional, and their characteristics. The document also provides logical formats (for example VICS link locations) and TPEG/ALERT-C physical format specifications (including formats for ETLs and Korean node-link ID references) in its annexes. The standard defines requirements for physical formats but does not mandate a single physical implementation format.

Scope

ISO 17572-2:2018 specifies the pre-coded location referencing method (pre-coded profile) for intelligent transport systems. It defines the logical structure of pre-coded location references, their mandatory and optional components, coding rules and examples, and the requirements for physical formats. The standard includes annexes that give logical and physical format specifications for a range of traffic information exchange mechanisms — notably a logical format for VICS link locations and TPEG physical formats for ALERT‑C (TMC), ETLs and Korean node‑link identifier references.

Key topics and requirements

• Definition and data model for pre-coded location references (LRM components and relationships).
• Specification of mandatory versus optional elements for pre-coded references and encoding rules.
• Logical format examples (e.g., VICS link location logical format in an annex).
• TPEG physical format specifications for ALERT‑C (TMC) location references and ETLs (annexes covering encoding details).
• Support and encoding rules for Korean node‑link identifier references (annexes).
• Requirements and guidance for implementing physical formats without mandating a single wire/byte-level format.
• Guidance aimed at interoperability between mapping/geographic databases, traffic message protocols and ITS services.

Typical use and users

ISO 17572-2 is used by ITS implementers who need consistent, interoperable methods to reference locations in traffic and transport data exchanges. Typical users include traffic and transport authorities, ITS product vendors, telematics and navigation system manufacturers, map and GIS data providers, TMC/TPEG service providers, and integrators implementing traffic message encoding/decoding and backend distribution systems.

Related standards

ISO 17572 is a multi‑part series. Closely related parts include ISO 17572-1 (general requirements and conceptual model — revised versions exist within the series) and ISO 17572-3 (dynamic location references / dynamic profile). The standard is developed under ISO/TC 204 (Intelligent transport systems) and is commonly used alongside other ITS message and traffic information standards and national/local location referencing schemes.

FAQ

Q: What is this standard?

A: ISO 17572-2:2018 is the part of the ISO 17572 series that specifies the pre-coded location referencing method (pre-coded profile) for intelligent transport systems, including logical and physical format guidance for several traffic messaging protocols. It was published in September 2018 (Edition 3).

Q: What does it cover?

A: It covers the definition, structure and encoding rules for pre-coded location references used with geographic databases and ITS message systems. It includes logical format specifications (e.g., VICS link location) and TPEG physical-format annexes for ALERT‑C, ETLs and Korean node‑link ID references, plus requirements for physical formats.

Q: Who typically uses it?

A: Traffic authorities, ITS product developers, navigation and telematics vendors, map/GIS data providers, TPEG/TMC service operators and systems integrators who need standardized, interoperable location referencing for traffic and transport information.

Q: Is it current or superseded?

A: ISO 17572-2:2018 replaced earlier editions (for example 2015). As published in September 2018 (Edition 3) it is the authoritative pre-coded profile in the ISO 17572 series; users should check national/adopted versions or later ISO revisions to confirm current status before procurement or implementation.

Q: Is it part of a series?

A: Yes — ISO 17572 is a multi-part series on location referencing for geographic databases. Key companion parts are ISO 17572-1 (general requirements and conceptual model) and ISO 17572-3 (dynamic location references / dynamic profile).

Q: What are the key keywords?

A: location referencing, pre-coded location reference, LRM, ITS, TPEG, ALERT-C, VICS, ETL, node‑link ID, geographic database, traffic messaging, encoding
