IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://webapp.etsi.org/IPR/home.asp
).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Intelligent
Transport System (ITS).
The present document is in support of early implementations. ETSI TC ITS welcomes feedback in order to facilitate
future revisions.

Date of latest announcement of this EN (doa): 31 December 2010

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
),
