  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. C-ITS standarisation, testing and procurement

  10. Standards organizations IEEE 802.11p IEEE P1609 New TC starting ISO TC204: ITS (1993) J2735 J2945 ETSI TC ITS (2007) CEN TC278: RTTT (1992) 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. C-ITS standarisation, testing and procurement

  11. International Harmonization C-ITS standarisation, testing and procurement

  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). C-ITS standarisation, testing and procurement

  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 pre-requisite for successful procurement. C-ITS standarisation, testing and procurement

  14. Important standards C-ITS standarisation, testing and procurement

  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 C-ITS standarisation, testing and procurement

  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. C-ITS standarisation, testing and procurement

  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 identifierswhich are both internal and external to ITS-SUs, • related registries, • certification labs, • trust authorities and • a public key infrastructure. C-ITS standarisation, testing and procurement

  18. ITS station management • Several management issues are identified: • Local station management including interference and channel congestion management (ISO 24102-1) • Access technology management (ISO 21218) • Remote station management (ISO 24102-2) • Station-internal management communications (ISO 24102-4) • Path and flow management (ISO 24102-6) • Management of service advertisement (ISO 24102-5) • Management service access points (ISO 24102-3) • Early implementations do not need to implement all of this. Management standards are continuously extended. C-ITS standarisation, testing and procurement

  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 24102-6. C-ITS standarisation, testing and procurement

  20. Scenarios & Technologies • Required and feasible C-ITS scenarios & technologies: • Single-hop communications using FSAP (ISO 24102-5) over FNTP (ISO 29281-1) and 5,9 GHz (ISO 21215). • Roadside – Vehicle: Short sessions similar to EFC sessionsand 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. C-ITS standarisation, testing and procurement

  21. Scenarios & Technologies • End-to-end communication (e.g. Vehicle – Central) using IPv6(ISO 21210, ISO 16788, ISO 16789, ISO 18378, ISO 18380 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. C-ITS standarisation, testing and procurement

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

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

  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 2013. This test platform will be available from 2014 on for plug-tests. Please provide your implementation of FNTP, FSAP, IICP and ISO 21218 asapto STF 455!

  25. Conformance and interoperability testing C-ITS standardisation, testing and procurement

  26. Standards Releases C-ITS standarisation, testing and procurement

  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. C-ITS standarisation, testing and procurement

  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 C-ITS standarisation, testing and procurement

  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 C-ITS standarisation, testing and procurement

  30. Conclusions on Harmonization C-ITS standarisation, testing and procurement

  31. Harmonization topics Technical harmonization: • EU/US HTG1&3 recommendation • Merge IEEE WSMP and ISO FNTP into a single protocol • Merge IEEE WSA and ISO FSAP into a single protocol • Local dynamic map (LDM) • Various message sets from CEN, ISO, ETSI, SAE • BSM (SAE) vs. CAM/DENM (ETSI): co-existence planned • Other message sets: harmonization planned. C-ITS standarisation, testing and procurement

  32. Harmonization topics "Political" harmonization How to bring together car manufacturers, road operators / city authorities, cellular network operators? How to comply in a vehicle ITS-SU with the requirements for infrastructure C-ITS? How to agree on a viable and efficient protocol for geo-dissemination of information?
