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

Introduction
This part of ISO/TR 17465 provides the definition of the term “Cooperative-ITS” (or “C-ITS” in its
abbreviated form), and contains descriptions of C-ITS from several perspectives. It is anticipated that
“C-ITS” will replace “cooperative systems” in all relevant ITS standards published after September 2012.
Although the concept of cooperative-TS is easy to understand, its implementation can be complex because
of the need to provide several services using many applications, all potentially communicating with each
other and sharing data in a structured manner (cf. OSI data communication model). As such, the set of
standards required to implement a service will beneficially be composed of several parts. In order that
users can easily find the standards information that they require, ISO/TR 17465-2 provides the outline
of the common structure to be used for these multi-part standards, and a detailed description of the
reference standards to be used for the creation of each part and the content of each part. ISO/TR 17465-
3 will describe the “release” procedure to be adopted for future Cooperative-ITS-related standards.

Intelligent transport systems — Cooperative ITS —
Part 1:
Terms and definitions
1 Scope
This part of ISO/TR 17465 provides a definition of the term “Cooperative-ITS”. It is anticipated that
“Cooperative-ITS” will be used in place of “cooperative systems” in all relevant ISO/CEN standards in the
intelligent transport systems (ITS) domain. This definition is consistent with and heavily relies on the
1)
concept of an “ITS station” as specified in ISO 21217.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
cooperative-ITS
DEPRECATED: cooperative systems
subset of overall ITS that communicates and shares information between ITS stations and ITS applications
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: See 4.2 for further details.
Note 2 to entry: As an alternative to a “subset”, Cooperative-ITS could be viewed as a “paradigm” in overall ITS.
2.2
cooperative-ITS environment
communications environment that enables ITS stations to communicate with other ITS stations
supporting sharing of data between ITS applications using whatever communications networks are
available at their current locations and, if necessary, to seamlessly switch between networks as their
locations change
2.3
intelligent transport system
transport system in which advanced information, communication, sensor, and control technologies,
including the Internet, are applied to increase safety, sustainability, efficiency, and comfort
2.4
ITS application
instantiation of an ITS service that involves an association of two or more complementary ITS-S
application processes
Note 1 to entry: Fragments of an application can also reside in nodes that are not ITS stations.
[SOURCE: ISO 21217:2014, 3.9]

2.5
ITS service
functionality provided to users of intelligent transport systems designed to increase safety, sustainability,
efficiency, and/or comfort
[SOURCE: ISO 21217:2014, 3.11]
2.6
ITS station
functional entity comprised of an ITS-S facilities layer, ITS-S networking & transport layer, ITS-S access
layer, ITS-S management entity, ITS-S security entity, and ITS-S applications entity providing ITS services
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).
[SOURCE: ISO 21217:2014, 3.12]
2.7
ITS-S application process
element in an ITS station that performs information processing for a particular application, and uses
ITS-S service to transmit and receive information
[SOURCE: ISO 21217:2014, 3.19]
2.8
ITS-S service
communication functionality of an ITS-S that provides the capability to connect to other nodes
[SOURCE: ISO 21217:2014, 3.37]
2.9
local dynamic map
entity consisting of LDM data objects, services and interfaces for manipulating these LDM data objects
2)
[SOURCE: ISO/TS 18750:— , 3.3]
2.10
wireless communication platform
combination of hardware and software that provides facilities to enable data to be communicated by
wireless transmission
2.11
wireless Internet platform
combination of hardware and software that provides facilities that enable devices to use wireless
communications to access the Internet and the services available from it
2.12
bounded secured managed domain
ITS station providing elements of trust
3 Symbols and abbreviated terms
API application programme interface
BSMD bounded secured managed domain

4 Cooperative-ITS
4.1 General
Cooperative-ITS (C-ITS) is the terminology to be used in place of “cooperative systems” in new ITS-
related standards produced by ISO, ETSI, CEN, and other ITS standards development organizations.
The definition of cooperative-ITS in Clause 3 was developed through collaboration between ISO, ETSI,
CEN, and representatives from other standards development organizations, and can be found in a similar
version in the “Joint CEN and ETSI Response to Mandate M/453” dated 15 April 2010.
C-ITS is a subset of ITS in which ITS station units applying the principles of a bounded secured managed
domain (BSMD) communicate and share information with each other to assist or enable service provision,
and station units used in ITS that do not apply these BSMD principles of trust provide information to
each other in an interoperable manner to offer advice and/or facilitate actions. The objective of C-ITS is
to improve safety, sustain
