It should be applied on this provisional basis, so that information and experience of its practical application may be obtained.Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the European organization respo
5、nsible for its conversion to a European standard. A review of this publication will be initiated 2 years after its publication by the European organization so that a decision can be taken on its status at the end of its 3-year life. Notification of the start of the review period will be made in an a
6、nnouncement in the appropriate issue of Update Standards.According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into a European Standard, to extend the life of the Technical Specification or to withdraw it.

26、Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the r
27、ight 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 International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Internation
28、al 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 Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as
29、 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 documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Availa
30、ble 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 parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the
31、 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 order to decide whether it will be confirmed for a further three years, revised to become an International
32、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 withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the sub
33、ject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TS 18234-5 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems. ISO/TS 18234 consists of the following parts, under the general title Traffic and Travel Information (
34、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 Information (SNI) application Part 4: Road Traffic Message (RTM) application Part 5: Public Transport Infor
35、mation (PTI) application Part 6: Location referencing applications CEN ISO/TS 18234-5:2006vIntroduction The TPEG technology uses a byte-oriented stream format, which may be carried on almost any digital bearer with an appropriate adaptation layer. TPEG-messages are delivered from service providers t
36、o end-users, and are used to transfer information from the database of a service provider to an end-users equipment. This CEN ISO Technical Specification describes the Public Transport Information Application, its underlying data structure as well as the means of encoding and decoding hierarchically
37、 structured messages containing public (i.e. collective) transport information. This application is intended to provide service providers, including broadcasters, with a means to transmit to an end-user public transport related travel news. The scope of TPEG is intended to cover content as diverse a
38、s network disruption, cancellations and even aspects of timetable information. Messages generated can be classified to fit into user perceived categories. The underlying data elements used for these classifications are taken from a superset that, the designers believe, is a complete set of elements
39、needed to fully describe the broadest range of public transport information. The Broadcast Management Committee of the European Broadcast Union (EBU) 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 trav
40、el-related information in the multimedia environment. The TPEG technology, its applications and service features are designed to enable travel-related 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
41、 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) described 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 fi
42、rst application, for Road Traffic Messages. CEN/TC 278/WG 4, in conjunction with ISO/TC 204/WG 10, established a project group comprising the members 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 complet
43、e 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 Information Application, which is likely to be used by all service implementations to ensure appropriate referencing from one service source to another. P
44、art 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 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 ligh
45、t of initial implementation results. Thus a consistent suite of specifications, ready for wide scale implementation, was submitted to the CEN/ISO commenting process. In November 2001, after extensive response to the comments received and from many internally suggested improvements, all four parts we
46、re 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 location referencing method, which enables both map-based TPEG-decoders and non map-based ones to deliver either map-based location referencing or human reada
47、ble 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 18234 to provide comprehensive location referencing. Additionally Part 5, the Public Transport Information Application (TPEG-PTI, CEN ISO/TS 18234-5),
48、has been developed and been through the commenting process. This Technical Specification, CEN ISO/TS 18234-5, provides a full specification for the public (i.e. collective) transport information application. This document has been prepared by CEN/TC 278, Road Transport and Traffic Telematics in co-o
49、peration with ISO/TC 204, Intelligent Transport Systems. 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 Technical CEN ISO/TS 18234-5:2006vi Specification, all parts are fully inter-workable and no specific dependencies exist. This Technical Specification has the technical version number TPEG-PTI_3.0/001. CEN ISO/TS 18234-5:20061Traffic and Travel Information (TTI) TTI via Transport Proto
