The work of preparing International Standards is normally carried out through ISO technical committees.

26、 Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Interna

27、tional Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Stan

28、dards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such document

29、s, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the pare

30、nt committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in ord

31、er to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be wi

32、thdrawn. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TS 18234-4 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems

33、. ISO/TS 18234 consists of the following parts, under the general title Traffic and Travel Information (TTI) TTI via Transport Protocol Expert Group (TPEG) data-streams: Part 1: Introduction, numbering and versions Part 2: Syntax, Semantics and Framing Structure (SSF) Part 3: Service and Network Inf

34、ormation (SNI) application Part 4: Road Traffic Message (RTM) application Part 5: Public Transport Information (PTI) application Part 6: Location referencing applications CEN ISO/TS 18234-4:2006vIntroduction TPEG technology uses a byte-oriented stream format, which may be carried on almost any digit

35、al bearer with an appropriate adaptation layer. TPEG-messages are delivered from service providers to end-users, and are used to transfer application data from the database of a service provider to a users equipment. This document describes the Road Traffic Message application in detail. It should b

36、e remembered that the TPEG-RTM has been derived from earlier work that resulted in the RDS-TMC standards (EN ISO 14819-2). Upon analysis, RDS-TMC can be seen to drift into other application areas, where it covers a few public transport, parking and weather messages. TPEG-RTM is just one of several a

37、pplications required to provide a fully comprehensive traffic and travel information service, for example a service is likely to need public transport information, parking information and weather information these are or will be the subject of other TPEG-application specifications. Nevertheless, TPE

38、G-RTM, where reasonable, has included the ability to convey similar content to RDS-TMC, in order to offer considerable backwards compatibility and the prospect of automatically generating RDS-TMC messages from TPEG-RTM messages. The Broadcast Management Committee of the European Broadcast Union (EBU

39、) established the B/TPEG project group in autumn 1997 with the mandate to develop, as soon as possible, a new protocol for broadcasting traffic and travel-related information in the multimedia environment. The TPEG technology, its applications and service features are designed to enable travel-relat

40、ed messages to be coded, decoded, filtered and understood by humans (visually and/or audibly in the users language) and by agent systems. One year later in December 1998, the B/TPEG group produced its first public specifications. Two documents were released. Part 2 (TPEG-SSF, CEN ISO/TS 18234-2) des

41、cribed the Syntax, Semantics and Framing structure, which will be used for all TPEG applications. Part 4 (TPEG-RTM, CEN ISO/TS 18234-4) described the first application, for Road Traffic Messages. CEN/TC 278/WG 4, in conjunction with ISO/TC 204/WG 10, established a project group comprising the member

42、s of B/TPEG and they have continued the work concurrently since March 1999. Since then two further parts have been developed to make the initial complete set of four parts, enabling the implementation of a consistent service. Part 3 (TPEG-SNI, CEN ISO/TS 18234-3) describes the Service and Network In

43、formation Application, which is likely to be used by all service implementations to ensure appropriate referencing from one service source to another. Part 1 (TPEG-INV, CEN ISO/TS 18234-1) completed the work, by describing the other parts and their relationships; it also contains the application IDs

44、 used within the other parts. In April 2000, the B/TPEG group released revised Parts 1 to 4, all four parts having been reviewed and updated in the light of initial implementation results. Thus a consistent suite of specifications, ready for wide scale implementation, was submitted to the CEN/ISO co

45、mmenting process. In November 2001, after extensive response to the comments received and from many internally suggested improvements, all four parts were completed for the next stage: the Parallel Formal Vote in CEN and ISO. But a major step forward has been to develop the so-called TPEG-Loc locati

46、on referencing method, which enables both map-based TPEG-decoders and non map-based ones to deliver either map-based location referencing or human readable information. Part 6 (TPEG-Loc, CEN ISO/TS 18234-6) is now a separate specification and is used in association with the other parts of CEN ISO/TS

47、 18234 to provide comprehensive location referencing. Additionally Part 5, the Public Transport Information Application (TPEG-PTI, CEN ISO/TS 18234-5), has been developed and been through the commenting process. This Technical Specification, CEN ISO/TS 18234-4, provides a full specification provides

48、 a full specification for the Road Traffic Message application. CEN ISO/TS 18234-4:2006vi During the development of the TPEG technology a number of versions have been documented and various trials implemented using various versions of the specifications. At the time of the publication of this Techni

49、cal Specification, all parts are fully inter-workable and no specific dependencies exist. This Technical Specification has the technical version number TPEG-RTM_3.0/003.
