24、:2006iv Foreword ISO (the International Organization for 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 w
25、hich 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 International Electrotechnical Commission (IEC) on all
26、 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 Standards adopted by the technical committees are c
27、irculated 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 documents, a technical committee may decide to publish
28、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 parent committee casting a vote; an ISO Technical S
29、pecification (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 with a view to deciding whether it should be confirme
30、d for a further three years, revised to become an International Standard, or withdrawn. In the case of a confirmed ISO/PAS or ISO/TS, it is reviewed again after six years at which time it has to be either transposed into an International Standard or withdrawn. Attention is drawn to the possibility t
31、hat 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 24530-3 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 204, Intell
32、igent transport systems, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). Throughout the text of this document, read “.this European pre-Standard.” to mean “.this Technical Specification.”. ISO/TS 24530 consists of the following parts, under the gener
33、al title Traffic and Travel Information (TTI) TTI via Transport Protocol Experts Group (TPEG) Extensible Markup Language (XML): Part 1: Introduction, common data types and tpegML Part 2: tpeg-locML Part 3: tpeg-rtmML Part 4: tpeg-ptiML CEN ISO/TS 24530-3:2006vIntroduction TPEG in XML (tpegML) provid
34、es the solution to diverse requirements for the ultimate delivery of TPEG applications (potentially simultaneously) via for example ARIB, ATSC, DAB, DVB and the Internet. This will solve the minimal adaptation layers requirement and without doubling up on message carousels, which are handled at diff
35、erent layers of the protocol stacks. The original 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 to end-users, and are used to transfer application data fro
36、m the database of a service provider to an end-users equipment. TPEG binary was initially designed to meet a particular brief, from the EBUs Broadcast Management Committee; to develop a new protocol for Traffic and Travel Information, for use in the multimedia broadcasting environment. TPEG applicat
37、ions were developed with service and transport features, which enable travel-related messages to be coded, decoded, filtered and understood both by humans (visually and/or audibly) and by agent systems. This brief was also endorsed by the EBU TTI Broadcast Strategy Team, who recognized the vital imp
38、ortance of a bearer independent TTI protocol. The development of TPEG binary technology is excellently matched both technically and economically to DAB and possibly to internet bearers, where of the order of up to 10 kbits/s is considered acceptable. However other bearers such as ARIB, ATSC and DVB
39、may be able to offer much higher data rates with economic and technical utility. Nevertheless these bearers are highly structured (layered) in their ability to handle transparent data services and they include mechanisms suitable for carousel delivery, which would require a considerably different TP
40、EG data structure before real transparency could be achieved. Another potential use of tpegML is provided to Service Providers who would have a standardised message generation interface, yet be able to develop systems suited to their own requirements. This will enable Service Providers to exchange p
41、re-edited information regardless of their message generation systems and be substantially language independent. tpegML has been developed using the DTD approach, which allows the use of different language entity files to easily provide a truly language independent service. This approach has the adva
42、ntage that tpegML files can be rendered in any language, provided the language entity file is available to the internet browser. This document provides English language entity files only. For other languages the entity files in this document only require direct translation. The development of this I
43、SO/TS 24530 series was undertaken jointly with European Broadcasting Union B/TPEG Group, which has evolved into the TPEG Forum Standards Task Force. Attention is drawn to the EBU sponsored TPEG Forum development principles, which require all inputs containing IPR to be declared during drafting work.
44、 No such declarations have been made. CEN ISO/TS 24530-3:2006blank1Traffic and Travel Information (TTI) TTI via Transport Protocol Experts Group (TPEG) Extensible Markup Language (XML) Part 3: tpeg-rtmML 1 Scope This document establishes the XML encoding of the method of the Road Traffic Message app
45、lication. The TPEG-RTM Application is intended to convey information to road users. The information provided relates to event and some status information on the road network and on associated infrastructure affecting a road journey. For example, limited information about abnormal operation of links
46、in the network may be included, such as ferries, lifting-bridges, etc. The TPEG-RTM Application has the broad objective to allow the generation of Traffic and Travel Information (TTI) messages, for delivery to the end-user by one or more bearers. A hierarchical methodology has been developed to allo
47、w the creation of messages from a set of TPEG-RTM tables, which are essentially word-oriented and cover most needs. These TPEG-RTM tables (essentially word-oriented data object dictionaries) comprise a wide ranging ability to describe a TTI event and some status information, introducing new precisio
48、n in a number of areas such as “Vehicle types”, “Positional information on the carriageway” and “Diversion routing advice”. It is vital, for further understanding of this document, to have more than a passing understanding of the TPEG-RTM binary specification which describes, among other things, in
49、a step-by step approach: Message Management, Level One Classes and how they are structured, hierarchically to provide a full Road Traffic Message together with the TPEG Location Referencing system. 2 Normative references The following referenced documents are indispensable for the application of this document.
