Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information.
The committee responsible for this document is ISO/TC 204, Intelligent transport systems.
ISO/TR 17465 consists of the following parts, under the general title Intelligent transport systems —
Cooperative ITS:
— Part 1: Terms and definitions
— Part 2: Guidelines for standards documents
— Part 3: Release procedures for standards documents
This includes an Annex that provides examples of the way that the guidance it contains should be applied
to multi-part standards.

Introduction
As Cooperative-ITS involves many services provided using a large number of applications all
communicating with each other and sharing data, it is very likely that some standards will become
very large. This will be particularly true where a particular standard documents the requirements for a
particular service or set of applications. It is thus likely that in some instances, multi-part standards will
be required so that finding particular aspects of a standard can be made easier.
In order for users to quickly find the standard’s information that they require in multi-part standards,
this part of ISO/TR 17465 provides guidance on the common structure to be used for the parts in
these multi-part standards. This will mean that a specific number is always used for each part, so that
Architecture/Application will always be part 1, ITS-station Management will always be part 2, Security
Set will always be part 3, etc. This part of ISO/TR 17465 also describes the relations between the
different parts of these standards, e.g. the relationship between architectural elements and data sets.
The use by multi-part standards of the structure described in this Technical Report does not remove the
obligation for those creating standards to involve other Technical Committees and/or Working Groups
in the creation of a particular standard. Thus, for example, the part of the standard that describes the
provisions for protection of privacy data and requirements for security of data and data transmissions
should be created in explicit coordination with the CEN/ISO working group responsible for overall C-ITS
Security and Privacy.
The need for the involvement of other Technical Committees and/or Working Groups will depend on the
scope and contents of the multi-part standard. There might be need for this involvement to be identified
in the New Work Item Proposal from which the multi-part standard is to be created and for a template
to be created so that this is done in a consistent way for all multi-part standards.
This Technical Report is thus only for use with standards that relate to Cooperative-ITS. Its contents
need not be applied to the ISO TC 204 and CEN TC 278 standards that do not specify information
exchanges because they are not relevant to those standards (such as standards for stand-alone systems
that acquire information only from sensors).

Intelligent transport systems — Cooperative ITS —
Part 2:
Guidelines for standards documents
1 Scope
This part of ISO/TR 17465 provides guidance for the structure that is to be used in multi-part ISO/CEN
standards for particular services or applications to be included in Cooperative-ITS. The guidance in this
part of ISO/TR 17465 may also be considered for use in multi-part standards for other ITS services and
applications.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
Cooperative-ITS
C-ITS
subset of overall ITS (2.2) that communicates and shares information between ITS stations (2.5) and ITS
applications (2.3) to give advice or facilitate actions with the objective of improving safety, sustainability,
efficiency, and comfort beyond the scope of stand-alone systems
Note 1 to entry: For further details and the justification of this definition, see ISO/TR 17465-1.
2.2
intelligent transport system
ITS
transport systems in which advanced information, communication, sensor and control technologies,
including the internet, are applied to increase safety, sustainability, efficiency, and comfort
2.3
ITS application
instantiation of an ITS service (2.4) that involves an association of two or more complementary ITS-S
application processes (2.6)
Note 1 to entry: Fragments of an application may also reside in nodes that are not ITS stations (2.5).
[SOURCE: ISO 21217:2014, 3.9]
2.4
ITS service
functionality provided to users of intelligent transport systems (2.2) designed to increase safety,
sustainability, efficiency, or comfort
[SOURCE: ISO 21217:2014, 3.11]
2.5
ITS station
ITS-S
functional entity comprised of an ITS-S facilities layer, ITS-S networking and transport layer, ITS-S
access layer, ITS-S management entity, ITS-S security entity, and ITS-S applications entity providing ITS
services (2.4)
Note 1 to entry: From an abstract point of view, the term “ITS station” refers to a set of functionalities. The
term is often used to refer to an instantiation of these functionalities in a physical unit. Often, the appropriate
interpretation is obvious from the context. The proper name of the physical instantiation of an ITS-S is ITS station
unit (ITS-SU) (2.8).
[SOURCE: ISO 21217:2014, 3.12]
2.6
ITS-S application process
element in an ITS station (2.5) that performs information processing for a particular application, and
uses ITS-S service (2.7) to transmit and receive information
[SOURCE: ISO 21217:2014, 3.19]
2.7
ITS-S service
communication functionality of an ITS-S that provides the capability to connect to other nodes
[SOURCE: ISO 21217:2014, 3.37]
2.8
ITS station unit
ITS-SU
implementation of an ITS-S (2.5)
