  15. SAE Ground Vehicle Systems Technical Committee J2735, Dedicated Short Range Communications (DSRC) Message Set Dictionary (Started:12/03/03) SCOPE (Extracted from J2735-D25 (08-12-08)) “This SAE Recommended Practice is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. This SAE Recommended Practice specifies standard message sets, data frames and data elements for use by applications intended to utilize the 5.9 GHz Dedicated Short Range Communications for Wireless Access in Vehicular Environments (DSRC/WAVE, referenced in this document simply as “DSRC”), communications systems. The scope is limited to specifying initial representative message structure and providing sufficient background information to allow readers to properly interpret the DSRC standards and message definitions from the point of view of an application developer.” STATUS Draft J2735-D26, pending approval in 2008 and publication in 2009 CONTACT T. Schaffnit tom@schaffnit.com Related Projects – SAE J2735

  16. Dedicated Short-Range Communications (DSRC) provide communications between a vehicle and the roadside in specific locations, for example toll plazas. They may then be used to support specific Intelligent Transport System applications such as Electronic Fee Collection. DSRC are for data-only systems and operate on radio frequencies in the 5,725 MHz to 5,875 MHz Industrial, Scientific and Medical (ISM) band. DSRC systems consist of Road Side Units (RSUs) and the On Board Units (OBUs) with transceivers and transponders. The DSRC standards specify the operational frequencies and system bandwidths, but also allow for optional frequencies which are covered (within Europe) by national regulations. DSRC systems are used in the majority of European Union countries, but these systems are currently not totally compatible. Therefore, standardization is essential in order to ensure pan-European interoperability, particularly for applications such as electronic fee collection, for which the European imposes a need for interoperability of systems. Standardization will also assist with the provision and promotion of additional services using DSRC, and help ensure compatibility and interoperability within a multi-vendor environment. CEN TC 278 produced the following standards: EN 12253, EN 12795, EN 12834 [ISO 15628] and EN 13372 for DSRC. Reference: http://www.etsi.org/website/technologies/DSRC.aspx Contact: K.

The 13th Global Standards Collaboration meeting (Boston, USA, July 2008) Recognizing: a) resolution GSC-9/6 (GRSC): Supporting Automotive Crash Notification (ACN) by Public Wireless Communications Networks; b) resolution GSC-10/07: (GRSC) Supporting Automotive Crash Notification (ACN) by Public Wireless Communications Networks; c) resolution GSC-11/08: (GRSC) Automotive Crash Notification (Revised); d) resolution GSC-11/09: (GRSC) Support for Vehicle Safety Messaging; and e) resolution GSC-12/10 (GRSC) GSC ITS Task Force. ITU-T GSC-13 Study Activity

  21. Considering: a) that the lifetime of vehicles exceeds that of any particular generation of public wireless networks; b) that vehicle manufacturers in each part of the world design and manufacturer vehicles for others parts of the world; c) that there are very large vehicle populations; d) that international harmonisation of standards for communications for vehicle safety is desirable in advance of deployment of vehicles using such communications; e) that many governments have made reducing vehicle deaths and injuries a priority; f) that vehicle crashes can be reduced by communicating information about dangerous conditions to vehicles, or by communicating directly with vehicles to provide safety related services; g) that several key issues to enable such services require international coordination and coordination between and among Participating Standards Organizations (PSOs); h) that ITU-T APSC TELEMOV is chartered as a cooperation group on all aspects of standardization related to telecommunications within and for motor vehicles and has been hosting the GSC ITS Task Force since GSC-11 (see: http://www.itu.int/ITU-T/specialprojects/ apsc/special-actions.html); and i) that the GSC ITS Task Force has delivered a set of recommendations for standards collaborations activities in support of automotive crash notification (ACN), vehicle safety communications (VSC), software reconfigurable radios (SRR) and location referencing (gsc12_open_26: GSC ITS TF Report to GSC-12 v1.2 2007-06-18.doc). ITU-T GSC-13 Study Activity

  22. Resolves: 1) to endorse the continuation of the GSC ITS Task Force hosted by ITU-T APSC TELEMOV and requests the Task Force to: a) use the recommendations in the report as the basis for ongoing work; b) serve as a coordination point for global standardization activities and further the recommendations noted in the report; and in particular to recommend and facilitate specific mechanisms for this coordination; c) make recommendations to GSC on related spectrum issues and technologies for VSC, including an approach for development of specific ITS protocols to support VSC at 700MHz; d) recommend the scope for specific standards needed to enable Software Reconfigurable Radio (SRR) for automotive applications at the next GSC meeting; and e) report on progress in each of these areas at the next GSC meeting; and 2) to request the Participating Standards Organisations to review the GSC ITS Task Force report and their national/regional activities in each of the topic areas and report on progress. ITU-T GSC-13 Study Activity

  23. Background Sponsor: TC 204 WG 16 • When: 2-4 September 2008 • Where: Holiday Inn Chicago Mart Plaza, Chicago, IL • Scope and purpose: – to disseminate information from: current standardization efforts around the world experience gained in prototyping of equipment and software initial results from real-world tests being conducted by various programs, projects and collaborations around the world – to decide how best to incorporate lessons learned into a set of global harmonized standards as openly and as efficiently as possible Joint Workshop on 5.9 GHz Vehicular Communications

  24. Tentative Outline: – Session 1 (2 September 1PM – 8PM): Status of standardization efforts (CALM M5 / Lower layer SAPs / Management / FAST networking / Architecture, IEEE 802.11p, ETSI TC ITS WG2 Architecture / WG3 networking / WG4 PHY layer / …) – Session 2 (3 September 8AM – 12PM): Status of various prototyping and testing efforts (VICC program, CVIS project, C2C-CC testing, …) – Session 3 (3 September 2PM – 6PM): Development of consensus on the requirements for V2V and V2I 5.9 GHz communication systems and identification of areas in the current standards that need to be changed/harmonized – Session 4 (4 September 7AM – (8AM!) – 1PM): Detailed technical discussions of what is currently missing in the standards (if anything) and development of a plan to achieve a set of technically complete, harmonized standards (who is responsible for what and a schedule). Joint Workshop on 5.9 GHz Vehicular Communications

  25. The idea is to take the set of overlapping standards from ISO, IEEE, ETSI and IETF, and develop them into a set of standards that are not overlapping but still complete ( mutually exclusive and collectively exhaustive). • To achieve this, the meeting proposes the following: – The ITS Station Reference Architecture shown above and presented by Knut Evensen, should be generally accepted as the common reference architecture and form the basis for the standards consolidation. – The next task is to decide on who takes the lead to develop and maintain the various technical standards, e.g. security, radio interfaces, geo-referenced protocols. – One example: The revision of the current ETSI, ISO and IEEE standards relevant to P1609, will be accomplished in an open, joint cooperation between ETSI, IEEE and ISO where relevant requirements from ISO and ETSI amend and extend P1609. Relevant ISO standards, e.g. ISO 21215, 21217, 24102, 29281, should reference IEEE 802.11p and P1609 where relevant and vice versa. Chicago Meeting Proposal

  26. The cooperative work on 1609 should form an ad-hoc working group based on Webex or similar. This will be done by invitation to mail reflector ETSI TC ITS, IEEE P1609, 802.11p and ISO CALM. Hans-Joachim Fischer will take the lead to send out an invitation for the first meeting within two weeks. • Scott Cadzow will take the lead to invite on security to send out an invitation for the first meeting within two weeks. • Andreas Festag (to be confirmed!) will take the lead to invite on Geo protocols and send out an invitation for the first meeting within two weeks.
