Full title and description

Intelligent transport systems — Localized communications — Communication protocol messages for global usage. This standard specifies localized message formats and related APDUs (Service Advertisement Message, Service Response Message) and basic procedural requirements intended for use in ITS localized communications environments.

Abstract

ISO 16460:2021 defines the Localized Message (LM) format (an NPDU for networking/transport layers without routing), the Service Advertisement Message (SAM) and the Service Response Message (SRM) APDUs to be carried in an LM, and associated basic procedural requirements. The specification relies in part on normative references to IEEE 1609.3 and is intended to be complemented by context-specific procedures and SAP descriptions (for example for ITS stations per ISO 21217 or for WAVE devices per IEEE 1609.0).

Scope

This document specifies message formats and basic procedures for localized communications used in Intelligent Transport Systems (ITS). It covers the LM data-unit structure and the APDUs for service advertisement and responses (SAM and SRM), together with the minimal procedural requirements necessary to support those exchanges. Complete application procedures and service access point (SAP) definitions are out of scope and must be provided according to the specific ITS context (for example an ITS station per ISO 21217 or WAVE device contexts per IEEE 1609.0).

Key topics and requirements

• Definition of the Localized Message (LM) NPDU format for non-routed transport of communications.
• Specification of Service Advertisement Message (SAM) APDU structure for announcing services.
• Specification of Service Response Message (SRM) APDU structure for acknowledging SAMs.
• Basic procedural requirements for exchanging SAM and SRM within LM messages.
• Normative referencing and interoperability considerations with IEEE 1609.3 (WAVE networking/transport protocols) and contextual linkage to ISO 21217 (ITS station reference architecture) and IEEE 1609.0.

Typical use and users

Implementers and integrators of intelligent transport systems, automotive and roadside equipment manufacturers, ITS solution architects, test laboratories and certification bodies, and standards bodies working on ITS communications profiles will use this standard to design and validate localized communications message formats and basic exchange procedures.

Related standards

ISO 16460:2021 updates and replaces earlier technical-specification work under ISO/TS 16460:2016. It is intended to be used alongside IEEE 1609.3 (WAVE networking/transport), IEEE 1609.0 (WAVE architecture), and ISO 21217 (ITS station reference architecture) when defining full operational procedures and SAPs.

FAQ

Q: What is this standard?

A: ISO 16460:2021 is an international standard that specifies localized communications message formats (LM, SAM, SRM) and basic procedures for use within Intelligent Transport Systems.

Q: What does it cover?

A: It covers the NPDU-format Localized Message (LM), the APDUs for Service Advertisement (SAM) and Service Response (SRM), and related basic procedural requirements; it does not define full application-layer procedures or SAP specifications, which must be supplied per the intended ITS context.

Q: Who typically uses it?

A: ITS equipment manufacturers, system integrators, testing and certification bodies, ITS planners and standards developers use this standard to ensure consistent localized-message handling and basic service advertisement/response behaviours.

Q: Is it current or superseded?

A: ISO 16460:2021 is the current published International Standard (published April 2021); it succeeded ISO/TS 16460:2016, which was withdrawn when the 2021 International Standard was published.

Q: Is it part of a series?

A: It relates to a family of ITS standards and technical specifications (for example ISO 21217 for ITS station architecture and IEEE 1609.x WAVE standards) and should be used in conjunction with those documents for complete implementations.

Q: What are the key keywords?

A: Localized Message (LM), Service Advertisement Message (SAM), Service Response Message (SRM), ITS, WAVE, IEEE 1609.3, message format, localized communications.
