Introduction
Intelligent Transport Systems (ITS) are systems to support transportation of goods and humans with information and
communication technologies in order to efficiently and safely use the transport infrastructure and transport means (cars,
trains, planes, ships). Elements of ITS are standardized in various standardisation organisations, both on an international
level at e.g. ISO TC204, and on regional levels, e.g. in Europe at ETSI TC ITS and at CEN TC278.
The present document specifies the architecture of communications in ITS (ITSC) supporting a variety of existing and
new access technologies and ITS applications. The term ITSC denotes communications protocols, related management
and additional functionality. The present document is arranged as a tool-box, i.e. conformance with the present
document does not require to implement the whole functionality illustrated and partly specified in the present document.
ITSC is to a large extent independent from specific communication technologies and specific ITS applications. The
ITSC architecture is intended to be an open systems architecture, i.e. an architecture that is open and not proprietary.
Activities related to the scope of the present document are e.g. the European projects:
• COMeSafety (http://www.comesafety.org),
• COOPERS (http://www.coopers-ip.eu),
• CVIS (http://www.cvisproject.org),
• FRAME (http://frame-online.net),

- WG18, jointly developing standards with CEN TC278 WG16 on cooperative systems,
• IEEE 802.11 [i.1] /p and 1609 WAVE,
other research projects.
ITS applications make use of wireless communications:
• Communications between mobile ITS stations (vehicles), and between mobile ITS stations and fixed ITS
stations (roadside installations), with single-hops or multiple hops between the source and destination ITS
stations.
• Access to public and private (local) networks including the global Internet.
• Infrastructure and satellite broadcast.

1 Scope
The present document specifies the global communication architecture of communications for Intelligent Transport
Systems (ITSC). This version of the present document is dedicated to the road transport context.
The present document on the ITSC architecture specifies mandatory and optional elements and interfaces of ITSC.
Some elements of ITS applications, especially those directly related to ITSC, are also considered.
The present document is enabling different implementation architectures as presented in the informative annex B.

Introduction
Intelligent Transport Systems (ITS) are systems to support transportation of goods and humans with information and
communication technologies in order to efficiently and safely use the transport infrastructure and transport means (cars,
trains, planes, ships). Elements of ITS are standardized in various standardisation organisations, both on an international
level at e.g. ISO TC204, and on regional levels, e.g. in Europe at ETSI TC ITS and at CEN TC278.
The present document specifies the architecture of communications in ITS (ITSC) supporting a variety of existing and
new access technologies and ITS applications. The term ITSC denotes communications protocols, related management
and additional functionality. The present document is arranged as a tool-box, i.e. conformance with the present
document does not require to implement the whole functionality illustrated and partly specified in the present document.
ITSC is to a large extent independent from specific communication technologies and specific ITS applications. The
ITSC architecture is intended to be an open systems architecture, i.e. an architecture that is open and not proprietary.
Activities related to the scope of the present document are e.g. the European projects:
• COMeSafety (http://www.comesafety.org),
• COOPERS (http://www.coopers-ip.eu),

ITS applications make use of wireless communications:
• Communications between mobile ITS stations (vehicles), and between mobile ITS stations and fixed ITS
stations (roadside installations), with single-hops or multiple hops between the source and destination ITS
stations.
• Access to public and private (local) networks including the global Internet.
• Infrastructure and satellite broadcast.
