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

This Technical Report provides an informative ‘framework overview’ of Cooperative Intelligent
Transport Systems (C-ITS). It is intended to be used alongside ISO 17427-1, ISO/TR 17465-1 and other
parts of ISO 17465, and ISO 21217. Detailed specifications for the application context will be provided
by other ISO, CEN and SAE deliverables, and communications specifications will be provided by ISO,
IEEE and ETSI.
Introduction
Intelligent transport systems (ITS) are transport systems in which advanced information,
communication, sensor and control technologies, including the Internet, are applied to increase safety,
sustainability, efficiency, and comfort.
A distinguishing feature of ‘ITS’ are their communication with outside entities.
Some ITS systems operate autonomously, for example, ‘adaptive cruise control’ uses radar/lidar and/or
video to characterize the behaviour of the vehicle in front and adjust its vehicle speed accordingly. Some
ITS systems are informative, for example, ‘Variable Message Signs’ at the roadside, or transmitted into
the vehicle, provide information and advice to the driver. Some ITS systems are semi-autonomous, in
that they are largely autonomous, but rely on ‘static’ or ‘broadcast’ data, for example, GNSS (3.9) based
‘SatNav’ systems operate autonomously within a vehicle but are dependent on receiving data broadcast
from satellites in order to calculate the location of the vehicle.
Cooperative Intelligent Transport Systems (C-ITS) are a group of ITS technologies where service provision
is enabled by, or enhanced by, the use of ‘live’, present situation related, dynamic data/information from
other entities of similar functionality [for example, from one vehicle to other vehicle(s)], and/or between
different elements of the transport network, including vehicles and infrastructure [for example, from the
vehicle to an infrastructure managed system or from an infrastructure managed system to vehicle(s)].
Effectively, these systems allow vehicles to ‘talk’ to each other and to the infrastructure. These systems
have significant potential to improve the transport network.
A distinguishing feature of ‘C-ITS’, is that data is used across application (3.1)/service boundaries.
ISO/TR 17465-1 provides a summary definition of C-ITS as a ‘subset paradigm of overall ITS that
communicates and shares information between ITS stations to give advice
