has 13 active working groups:
WG1: Architecture
WG3: ITS data base technology
WG4: Automatic vehicle and equipment identification
WG5: Fee and toll collection
WG7: General fleet and freight management
WG8: Public transport / emergency
WG9: Integrated transport information, management and
control
WG10: Traveler information systems

Intelligent Transport Systems (ITS)
WG11: Route guidance and navigation systems
WG14: Vehicle / roadway warning and control systems
WG16: Wide area communications / protocols and interfaces
WG17: Nomadic devices
WG18: Cooperative systems
• Several working groups work jointly together with WGs
from CEN TC278.
• TC204 is in the process of being re-structured
• ISO TC204 is THE global leading advocate for
standards on technologies improving safety, security,
efficiency and comfort of the world's transportation
system

Cooperative Intelligent Transport Systems
Cooperative ITS (C-ITS) is a subset of ITS in which
information is communicated and shared between
ITS station applications to facilitate actions and
decisions that improve ITS safety, sustainability,
efficiency and comfort beyond that achievable by
stand-alone systems.

Other SDOs
ETSI TC ITS, founded December 2007 upon an initiative of
members of ISO TC204 WG16, is focused on a slice of CITS promoted by the Car-to-Car Communications Consortium,
i.e. on car-centric communications and applications for road
safety and traffic efficiency.
IEEE 1609 working group is working on usage of 802.11(p) in
vehicular environment (US DSRC, WAVE). This is a sub-set
of C-ITS with a similar target as ETSI TC ITS.
SAE is specifying message sets (BSM) for US DSRC.

Cooperative Intelligent Transport Systems
C-ITS is the technical topic of
• mandate M/453 "Standardization mandate
addressed to CEN, CENELEC AND ETSI in the
field of information and communication
technologies to support interoperability of cooperative systems for intelligent transport in the
European community" of the European
Commission
• EU (EC DG INFSO) / US (DOT/RITA) task force on
harmonization in standardisation (results of harmonization
task groups 1 and 3)

Research activities - Technologies
Some examples of EU projects on basic
technologies:
• CVIS and COOPERS implemented and validated
first versions of ITS standards from ISO TC204
WG16 (CALM).
• ITSSv6 works on IPv6 in the ITS station
• SAFESPOT worked on vehicular networks for road
safety
• GeoNet worked on geo-dissemination of
information in C-ITS.

Research activities - Support
Supporting EU projects:
• COMeSafety is in support of European Community
wide implementation and deployment of C-ITS,
effective EU-US and international cooperation,
and deployment preparation.
• iCarSupport sets out to convince the public at
large that ITS technologies and applications are an
investment for Europe’s future
• eCoMove works on cooperative mobility systems
and services for energy efficiency

Research activities - Framework
Further EU projects:
• FRAME is to provide a minimum stable framework
architecture necessary for the deployment of
integrated and inter-operable ITS within the
European Union.
• FOTsis is a large scale field testing of the road
infrastructure management systems needed for
the operation of close-to-market cooperative I2V,
V2I & I2I technologies.

Industry initiatives towards harmonization
• Six major infrastructure suppliers announced
their joint work towards a common set of standards
for Cooperative Mobility services.
• European vehicle manufacturers announced a
Memorandum of Understanding on Cooperative
ITS (C-ITS).
However these two big groups have very different
basic requirements.
Harmonization between these groups is a prerequisite for successful procurement.

Standards release 1 for C-ITS
• The definition of a Release 1 for C-ITS at CEN,
ETSI and ISO started. Release 1 aims on
identifying a set of standards which "fit together"
allowing development of conformant
implementations by selection of those standards
required for a specific conformance profile.
However ETSI is solely working on an ETSI Release
1, ignoring standards from CEN and ISO. Comparing
the current "official" ETSI proposal and a proposal
made by CEN/ISO experts, almost no overlap is
given.

Link applications to communications in a
global context
PT1601 is drafting two CEN/ISO Technical Specifications:
• TS 17419 "Co-operative systems — Classification and management
of ITS applications in a global context“
• TS 17423 "Co-operative systems - ITS application requirements for
selection of communication profiles"
related to C-ITS management (system enabler!) which will be
upgraded to EN/ISO standards.
PT1601's scope includes International Harmonization and
recommendations to the EC (on required registries and
infrastructure services).

ITS-S reference architecture (ISO 21217)
The ITS-S is defined as a
Bounded
Secured
Managed
Domain.
There are many other stations
used in ITS already today, which
are not following the principles of
BSMD.
Nevertheless
communications
between ITS-SUs = BSMEs and
other ITS station units has to be
possible.

Communications and applications in C-ITS
• Communications standards are already well developed and
available.
• Application and message set standards are in the process of
being developed.
• Essential (management) functionality of an ITS-SU, which
goes beyond the functionality of existing systems, is identified
but not yet fully standardized. Globally unique identifiers are
in the process of being identified, and will be subject of
registration.
"Simple" implementations (more or less silo-based) with
restricted functionality are possible based on existing C-ITS
standards, however the aspect of "trust" is not yet sufficiently
supported in standards and in the infrastructure (PKI).

Comm. profile selection (TS 17423)
In an ITS-SU, applications do not need to know about available communications
tools. Applications only present functional requirements.

Conformance and interoperability testing
ISO and CEN selected ETSI to develop test suites and test platforms. For
a number of communication standards from ISO and ETSI, and for
message set based applications from ETSI test suites already exist.
STF 455 funded by the EC under mandate M/453 currently is extending the
C-ITS test platform at ETSI to include the test suites for ISO base
standards of communication protocols.
Such a test platform is a prerequisite for conformance testing and
certification of equipment.
A demonstration is planned for the ITS world congress in Japan in autumn
2013. This test platform will be available from 2014 on for plug-tests.
Please provide your implementation of FNTP, FSAP, IICP and ISO 21218
asap to STF 455!

Procurement of C-ITS equipment
Conclusions
In a first procurement phase (in about three to five years from
now) the following C-ITS scenario is feasible:
• Single-hop roadside to vehicle communications using FSAP
over FNTP and 5,9 GHz. Short sessions similar to EFC
sessions and local information dissemination (e.g. SPAT at
intersections)
• Single-hop vehicle-to-vehicle communications using BSM /
CAM / DENM over FNTP and 5,9 GHz.
• Vehicle-to-infrastructure communication (and vice versa)
using IPv6 over cellular technology.
• Ordinary hot-spot communications with non-moving
stations.
• Local dynamic map (LDM) usage.

Procurement of C-ITS equipment
Conclusions
Geo-dissemination of information to remote destinations will
be efficiently reliable with IPv6 over cellular technology once
the cellular networks are prepared for this.
Geo-dissemination of information over narrowband channels
such as those at 5,9 GHz (GeoNetworking) with multiple
hops is very unlikely to be possible due to restrictions
imposed by the communication channel.

Procurement of C-ITS equipment
Conclusions
C-ITS will use several different communication technologies,
including
• ad-hoc (single-hop) communications (5,9 GHz, 63 GHz, ...)
• cellular networks (LTE, ...)
• Internet (IPv6)
The C-ITS architecture has the capability to finally cover all
application areas with mobility requirements (moving stations
– wireless communications).
There is one world and only one C-ITS!
