4 What C-ITS is! 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-alone systems.

9 Standardisation Arena May 2013 C-ITS standarisation, testing and procurement 9

10 Standards organizations ISO TC204: ITS (1993) New TC starting IEEE p IEEE P1609 CEN TC278: RTTT (1992) ETSI TC ITS (2007) J2735 J2945 ISO and CEN are leading advocates for technologies improving safety, security, efficiency and comfort of the world's transportation system. ESF GmbH is contributing to global standardization. May 2013 C-ITS standarisation, testing and procurement 10

11 International Harmonization May 2013 C-ITS standarisation, testing and procurement 11

12 Harmonization between SDOs 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). May 2013 C-ITS standarisation, testing and procurement 12

13 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. May 2013 C-ITS standarisation, testing and procurement 13

14 Important standards May 2013 C-ITS standarisation, testing and procurement 14

15 (C-) ITS architecture General architectural description of Intelligent Transport Systems and its cooperative elements. - FRAME - CEN/ISO TS 17417: Roles and responsibilities - CEN/ISO TS 17419: Classification and management of ITS applications in a global context - ISO 21217: Communications architecture May 2013 C-ITS standarisation, testing and procurement 15

16 ITS-S 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 = BSME and other ITS station units has to be possible. May 2013 C-ITS standarisation, testing and procurement 16

17 Classification & management of ITS applications (PT1601 TS 17419) C-ITS uses ITS-S applications and communications between ITS-SUs on the basis of TRUST (BSME). To establish trust requires globally unique identifiers which are both internal and external to ITS-SUs, related registries, certification labs, trust authorities and a public key infrastructure. May 2013 C-ITS standarisation, testing and procurement 17

18 ITS station management Several management issues are identified: Local station management including interference and channel congestion management (ISO ) Access technology management (ISO 21218) Remote station management (ISO ) Station-internal management communications (ISO ) Path and flow management (ISO ) Management of service advertisement (ISO ) Management service access points (ISO ) Early implementations do not need to implement all of this. Management standards are continuously extended. May 2013 C-ITS standarisation, testing and procurement 18

19 ITS application requirements for selection of communication profiles (PT1601 TS 17423) Connects applications to communications in a future-proof way: ITS-S application process present requirements and objectives for communications to the ITS-S management ITS-S management continuously monitors status of available communication tools. ITS-S management continuously monitors regulations and policies. ITS-S management automatically selects and updates appropriate communication protocol stacks for all flows of ITS-S application processes, see also ISO May 2013 C-ITS standarisation, testing and procurement 19

20 Scenarios & Technologies Required and feasible C-ITS scenarios & technologies: Single-hop communications using FSAP (ISO ) over FNTP (ISO ) and 5,9 GHz (ISO 21215). Roadside Vehicle: Short sessions similar to EFC sessions and local information dissemination (e.g. SPAT at intersections) Vehicle Vehicle: Information dissemination (e.g. BSM / CAM / DENM). Ordinary hot-spot communications (WiFi) with non-moving stations. May 2013 C-ITS standarisation, testing and procurement 20

21 Scenarios & Technologies End-to-end communication (e.g. Vehicle Central) using IPv6 (ISO 21210, ISO 16788, ISO 16789, ISO 18378, ISO and others) over cellular technology (GSM / LTE) and Internet. Geo-dissemination of information. Using IPv6 over CN and Internet to reach remote destinations Local dynamic map (LDM) usage. May 2013 C-ITS standarisation, testing and procurement 21

22 Scenarios & Technologies May 2013 C-ITS standarisation, testing and procurement 22

23 Conformance and Interoperability Testing May 2013 C-ITS standarisation, testing and procurement 23

24 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 This test platform will be available from 2014 on for plug-tests. Please provide your implementation of FNTP, FSAP, IICP and ISO asap to STF 455! Contact us: tp@its-testing.org May 2013 C-ITS standardisation, testing and procurement 24

26 Standards Releases May 2013 C-ITS standarisation, testing and procurement 26

27 Standards release 1 for C-ITS 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. May 2013 C-ITS standarisation, testing and procurement 27

28 ETSI Release 1 for C-ITS 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 May 2013 C-ITS standarisation, testing and procurement 28

29 ISO Release for C-ITS ISO TC204 approved a resolution on a release for C- ITS and created work items for conformity profiles: considering all relevant standards, not just ISO standards is preparing this in a joint cooperation with CEN aims on providing guidelines for usage May 2013 C-ITS standarisation, testing and procurement 29
