Cooperation ISO TC204 WG16 and ETSI TC ITS STF422
The demonstration of efficient cooperation between ISO TC204 WG16 (making base standards for communications in ITS) and ETSI TC ITS (making test suites for the ISO standards) reached the important milestone of finishing all work on both the ISO base standards and the ETSI test standards. As both sets of standards are cross-linked together by mandatory references, simultaneous publication is needed.
ISO CS got the revised drafts of the base standards for DIS ballot. The DIS ballot stage is sufficient for ETSI considering the required availability of a standard used in a mandatory reference. ETSI TC ITS is going to approve the test suites next week at the plenary meeting in Sophia Antipolis.
The work of ETSI TC ITS STF 422, who developed the test suites, was presented in Melbourne together with a vision of next steps, i.e. to validate these test suites at ETSI CTI.

ISO / ITU joint work
Based on a resolution of ISO TC204 approved at the Tampa meeting in October 2011 experts from ISO TC204 WG16 followed an invitation from ITU to have a meeting in Geneva in order to learn about possible contributions from ITU on the development and promotion of communication standards for ITS / C-ITS.
This meeting was a purely informative meeting without the power to have any decisions on behalf of ISO TC204. In order to speed up the process, Dr. Fischer from ESF GmbH was asked to provide information on the actual status of communication standards for ITS achieved since the Tampa meeting. You can download his informal report here.
ETSI STF 422 (Test suites for CALM Fast protocols) in Doha / Qatar
The next ETSI ITS workshop which aims on presenting latest results from CEN TC278 and ETSI TC ITS developed under mandate M/453 is scheduled for February 7th through 9th 2012 in Doha / Qatar.
The leader of STF 422, Dr. Fischer from ESF GmbH, gave a presentation on Conformance and interoperability testing of C-ITS protocol implementations compliant with standards from ETSI, CEN and ISO in Session 5 "Managing the five senses of ITS" on the extension of an existing ITS test platform at ETSI, which was originally designed to allow for conformance test of the ETSI ITS communication standards and application standards.
The extension will broaden the scope of testing at ETSI by supporting communications and applications standards from all SDOs working in the domain of C-ITS. A technical focus will be on the ISO CALM-specific efficient upper tester access, which constitues a standardized access for "no additional cost".

Software Implementations of CALM communication standards for C-ITS
ESF GmbH is going to provide software implementations of the set of "kernel standards" out of the Basic Set of Communication Standards (ISO CALM) for Co-operative ITS.
These software implementations are intended to be used as a basis to develop a test bed for C-ITS standards based on the concept of the Bounded Secured Managed Domain.
The purpose of this planned test bed is not just to allow for conformance test of communication protocols developed at ISO, but to support testing for C-ITS in general.
International Relations
Joint approach US / EU towards ITS!
Liaison agreement between ISO TC204 and ETSI TC ITS!
Cellular Networks
4th generation cellular networks are becoming potential candidates for road safety and traffic efficiency, complementing the functionality of ad-hoc access technologies 5,9 GHz and IR.
ETSI and CEN have started work items on LTE for Co-operative ITS.
On 6th of May 2011, DG MOVE from the European Commission informed about Studies - Intelligent Transport Systems. One of the essential documents presented there is the Final Report related to the ITS Action Plan, action area 4 "Integration of the vehicle into the transport infrastructure" , specific action 4.1 "Adoption of an open in-vehicle platform architecture for the provision of ITS services and applications, including standard interfaces".
This report was produced by Rapp Trans AG under the lead of Dr. Bernhard Oehry. It presents very essential facts and recommendations for C-ITS.
CEN TC 278
WG16 on co-operative systems
Harmoinzation of the Basic Set of CALM Communication Standards started. The first set of harmonized International Standards includes:
- ISO 21217, "ITS communication architecture"
- ISO 21218, "Medium service access points"
- ISO 24102-1, "ITS station management - Local management"
- ISO 24102-2, "ITS station management - Remote management" (new work item)
- ISO 24102-3, "ITS station management - SAPs"
- ISO 24102-4, "ITS station management - Station-internal management communications"
- ISO 24102-5, "ITS station management - Fast service advertisement protocol (FSAP)
- ISO 29281-1, "Non-IP networking - General requirements"
- ISO 29281-2, "Non-IP networking - Fast networking & transport protocol (FNTP"
- ISO 29281-3, "Non-IP networking - Legacy system support
ETSI TC ITS WG2 launched STF 422, which develops test specifications for EETS-DSRC HDR and CALM FAST services. The abstract test suites will be implemented with TTCN-3. Work started in March 2011. Stable drafts of three PICSs deliverables are available. Major results are expected until end of 2011. The project maintains an informative web site inviting interested parties to learn some details about the base standards, to follow the work, and provide contributions.
ETSI TC ITS WG2 will soon start development of a test suite for the suite of "IPv6" International Standards developed at ISO TC204 WG16.
The general assembly of ETSI elected a new general director. We wish Mr. Romero Saro, who got almost 69% ofthe votes, good success in his new position, and we are looking forward to a good cooperation in the scope of global standardization in the full scope of Cooperative ITS, and as requested by the EC in a letter to ETSI, sent in the context of mandate M/453.
On the ETSI web, three IPRs are listed which are considered to be essential for ITS.
This is a somewhat strange situation, as IPRs normally can be considered as a "show stopper" for a standard.
What are these IPRs? These IPRs are related to the standards currently being under development:
- TC ITS WG4, TS 102 687, "Intelligent Transport Systems (ITS); Decentralized Congestion Control Mechanisms for Intelligent Transport Systems operating in the 5 GHz range; Access layer part "
- TC ITS WG4, TS 102 724, "Intelligent Transport Systems (ITS); Harmonized Channel Specifications for Intelligent Transport Systems operating in the 5 GHz frequency band"
- TC ITS WG3, TS 102 636-6-1, "Intelligent Transport Systems (ITS); Vehicular Communications; Part 6: Internet Integration; Sub-part 1: Transmission of IPv6 Packets over GeoNetworking Protocols"
Who owns these IPRs? These IPRs are owned by
- Daimler AG / Germany
- DENSO AUTOMOTIVE Deutschland GmbH / Germany
- NEC Corporation
For more details, please check the ETSI web, or ask us.
ESF GmbH has withdrawn its support for these ETSI work items.
ITS Appliation Store.
An ITS application store is a key element for deployment of ITS. It was developed and tested by the CVIS project, based on the basic set of communcation standards CALM
Extended set of CALM communication standards
ISO TC204 WG16 extended the Basic Set of CALM Communication Standards:
- Developing a "Handover Architecture", which is also in support of "Distributed Congestion Control" - ISO 16445.
- Harmonize IEEE WAVE with CALM FAST and ETSI CAM/SAM/DENM - ISO 16440.
- Implement all variants of Geo-Routing (basic GeoNet protocols from the EU project GeoNet) in the CALM architecture- ISO 16444.
- IPv6 optimization - ISO 16788
- IPv6 security - ISO 16789
Work started at the meeting of ISO TC204 WG16 in Prague, in April 2011.
ITS 5 GHz based on 802.11 and amendment /p
- IS 21215 CALM M5 is the enabling standard for 5,9 GHz access technology based on IEEE 802.11, which now also includes the amendment p developed in TGp.
- ES 202 663 "European profile standard" provides a sub-set of functionality specified in IS 21215. Interfaces to the station management and the network layer are missing. Unfortuntely the published version of ES 202 663 is not compliant with IEEE 802.11.
ITS at ISO/CEN and at ETSI
Standardization of ITS started in ISO TC204, of which the name is "Intelligent Transport Systems", which maintains close relations with CEN TC278, practising joint development of standards. WG16 of this TC204 started in 2001 to develop the "Basic Set of ITS Communication Standards" under the work title "Communication Access for Land Mobiles" (CALM). The "root" for all communication standards in ITS is given by the published standard ISO 21217 "CALM Architecture".
In 2007, ETSI founded TC ITS, which was pushed by a number of experts from ISO TC204 WG16. The idea was two-fold, i.e to convert the ISO CALM standards into European Norms (EN) by referencing the ISO standards, and to develop the necessary test suites for conformance and interoperability testing. Currently, draft ETSI EN 302 665 "ITS communication architecture" is in public enquiry, i.e. the last ballot step prior to publication as an EN.
An observer, who is not familiar with the work done in ISO and ETSI, will be confused with two standards, one from ISO and one from ETSI, where both claim to specify the same "biest", i.e. the ITS communication architecture. Will there be two different ITSs? Reading line by line the two standards, three findings will happen:
- The ISO standard and the draft ETSI EN look very much the same.
- There are small differences.
- Draft EN 302665 seems to be a sub-set of ISO 21217.
The reader will conclude that there is no need for a new EN of this kind, re-typing the statements from an ISO standard. It would have been much better to have this EN 302 665 constructed in a way to have one single major mandatory reference to the already published ISO 21217, and to add missing parts, if needed. In any case, the reader should know, that an architecture standard mainly has to be understood as a tool-box of options, you can select for an implementation, and a dictionary of terms and definitions.
For the sake of deployment we hope, that a wrong view on "parallel development of two ITSs" will not settle in the mind of stake-holders. Best would be, ETSI revises its draft EN to make this clear.
In any case, if you have problems, please contact the ITS expert and ask for help. We are offering courses on ITS, and we will also guide you through your ITS projects.

Testing in ITS
Testing, especially conformance testing, is being done with TTCN-3. ETSI STF 398 has finalised the "ITS testing framework" guide EG 202 798. This EG provides
- guidance to identify the candidate implementations under tests (IUTs) for conformance testing, and the equipment under test (EUTs) for interoperability testing, i.e. answering the question "what is to be tested",
- guidance to define the applicable test procedures, i.e. answering the question "how is to be tested",
- guidance to develop the resulting test specifications and deliverables (for instance: TSS&TP, TP proforma, TTCN-3 test suite and documentation),
in the domain of global ITS, referring explicitly to the known activities of ISO (CALM) and ETSI. The first clauses in this EG are providing a more tutorial-like introduction, readable also for laymen in testing. The last clause requires specific knowledge on testing and is intended for testing experts.
First results from development of abstract test suites for CALM base standards and ETSI base standards are available.
Plug-tests are being prepared to run at ETSI.
We guide you through your testing project.
