Cooperative Intelligent Transport Systems
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

International
Harmonization


Harmonization between SDOs

May 2013

C

ITS standarisation, testing and procurement

12


ISO
/ CEN work jointly together and aim on
international harmonization with other SDOs and
stakeholders.


EU/US task force Harmonization Task Groups
HTG1 and HTG3 checked available standards
from various SDOs and presented
recommendations on harmonization. A set of
reports is publicly available.


There are liaisons between major SDOs on the
issue of message sets (BSM, CAM, DENM, SPAT,
...) and the usage of Local Dynamic Map (LDM).

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 pre
-
requisite for successful procurement.

station management

Several management issues are identified:


Local station management including interference and
channel congestion management (
ISO 24102

)


Access technology management (
ISO 21218
)


Remote station management (
ISO 24102

(

Path and flow management (

Management of service advertisement (
ISO 24102
-

)


Management service access points (
ISO 24102

)


Early implementations do not need to implement all of this.
Management standards are continuously extended.

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!

Standards Releases


Standards release 1 for C

C
-
ITS standarisation, testing and procurement

27


The
definition of a
Release 1

for
C
-
ITS at CEN, ETSI
and
ISO started. It is expected that a
Release



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.

ETSI Release 1 for C

28

In April 2013 ETSI TC ITS approved the ETSI Release
1 for C
-
ITS. This release is understood as a "list of
standards", which


is not complete (as a set)


refers partly to non
-
completed standards


does not define conformance profiles for equipment


does not provide guidelines of usage


refers to standards which are identified to be
unfortunate (see report from EU/US HTG 1&3)


refers to standards which are covered by IPRs
