16、2016(E) 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
17、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
18、 matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. Th
19、is document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). 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 o

27、d by the European Broadcasting Union (EBU) Broadcast Management Committee, who established the B/TPEG project group in the autumn of 1997 with a brief to develop, as soon as possible, a new protocol for broadcasting traffic and travel-related information in the multimedia environment. TPEG technolog
28、y, its applications and service features were 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. Originally, a byte-oriented data stream format, which may be carried on almost any di
29、gital bearer with an appropriate adaptation layer, was developed. Hierarchically structured TPEG messages from service providers to end-users were designed to transfer information from the service provider database to an end-users equipment. One year later in December 1998, the B/TPEG group produced
30、 its first EBU specifications. Two documents were released. Part 2 (TPEG-SSF, which became ISO/TS 18234-2) described the Syntax, Semantics and Framing structure, which was used for all TPEG applications. Meanwhile, Part 4 (TPEG- RTM, which became ISO/TS 18234-4) described the first application, for
31、Road Traffic Messages. Subsequently in March 1999, CEN TC 278/WG 4, in conjunction with ISO/TC 204/WG 10, established a group comprising members of the former EBU B/TPEG and this working group continued development work. Further parts were developed to make the initial set of four parts, enabling th
32、e implementation of a consistent service. Part 3 (TPEG-SNI, ISO/TS 18234-3) described the Service and Network Information application, used by all service implementations to ensure appropriate referencing from one service source to another. Part 1 (TPEG-INV, ISO/TS 18234-1) completed the series by d
33、escribing the other parts and their relationship; it also contained the application IDs used within the other parts. Additionally, Part 5, the Public Transport Information application (TPEG-PTI, ISO/TS 18234-5), was developed. The so-called TPEG-LOC location referencing method, which enabled both ma
34、p-based TPEG-decoders and non-map- based ones to deliver either map-based location referencing or human readable text information, was issued as ISO/TS 18234-6 to be used in association with the other applications parts of the ISO/TS 18234 series to provide location referencing. The ISO/TS 18234 ser
35、ies has become known as TPEG, generation 1. TPEG generation 2 When the Traveller Information Services Association (TISA), derived from former Forums, was inaugurated in December 2007, TPEG development was taken over by TISA and continued in the TPEG applications working group. It was about this time
36、 that the (then) new Unified Modelling Language (UML) was seen as having major advantages for the development of new TPEG applications in communities who would not necessarily have binary physical format skills required to extend the original TPEG TS work. It was also realized that the XML format fo
37、r TPEG described within the ISO/TS 24530 series (now superseded) had a greater significance than previously foreseen; especially in the content-generation segment and that keeping two physical formats in synchronism, in different standards series, would be rather difficult. As a result, TISA set abo
38、ut the development of a new TPEG structure that would be UML based this has subsequently become known as TPEG Generation 2. TPEG2 is embodied in the ISO/TS 21219 series and it comprises many parts that cover introduction, rules, toolkit and application components. TPEG2 is built around UML modelling
39、 and has a core of rules that contain the modelling strategy covered in Parts 2, 3, 4 and the conversion to two current physical formats: binary and XML; others could be added in the future. TISA uses an automated tool to convert from the agreed UML model XMI file directly into an MS Word document f
40、ile, to minimize drafting errors, that forms the Annex for each physical format. ISO 2016 All rights reserved vii PD ISO/TS 21219-19:2016 ISO/TS 21219-19:2016(E) TPEG2 has a three container conceptual structure: Message Management (ISO/TS 21219-6), Application (many ISO/TS 21219 parts) and Location
41、Referencing (ISO/TS 21219-7). This structure has flexible capability and can accommodate many differing use cases that have been proposed within the TTI sector and wider for hierarchical message content. TPEG2 also has many location referencing options as required by the service provider community,
42、any of which may be delivered by vectoring data included in the Location Referencing Container. The following classification provides a helpful grouping of the different TPEG2 parts according to their intended purpose: Toolkit parts: TPEG2-INV (ISO/TS 21219-1), TPEG2-UML (ISO/TS 21219-2), TPEG2-UBCR
43、 (ISO/TS 21219-3), TPEG2-UXCR (ISO/TS 21219-4), TPEG2-SFW (ISO/TS 21219- 5), TPEG2-MMC (ISO/TS 21219-6), TPEG2-LRC (ISO/TS 21219-7); Special applications: TPEG2-SNI (ISO/TS 21219-9), TPEG2-CAI (ISO/TS 21219-10); Location referencing: TPEG2-ULR (ISO/TS 21219-11), TPEG2-GLR (ISO/TS 21219-21), TPEG2-OL
44、R (ISO/TS 21219-22); Applications: TPEG2-PKI (ISO/TS 21219-14), TPEG2-TEC (ISO/TS 21219-15), TPEG2-FPI (ISO/ TS 21219-16), TPEG2-TFP (ISO/TS 21219-18), TPEG2-WEA (ISO/TS 21219-19), TPEG2-RMR (ISO/TS 21219-23). TPEG2 has been developed to be broadly (but not totally) backward compatible with TPEG1 to
45、 assist in transitions from earlier implementations, while not hindering the TPEG2 innovative approach and being able to support many new features, such as dealing with applications having both long-term, unchanging content and highly dynamic content, such as Parking Information. This Technical Spec
46、ification is based on the TISA specification technical/editorial version reference: SP13002/1.1/001viii ISO 2016 All rights reserved PD ISO/TS 21219-19:2016 Intelligent transport systems Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) Part 19: Weather
47、information (TPEG2-WEA) 1 Scope This part of ISO/TS 21219 defines the TPEG Weather (WEA) application for reporting weather information for travellers. It provides general weather-related information to all travellers and is not limited to a specific mode of transportation. This application does not
48、provide specific weather-related safety warnings to drivers; these are provided as Safety Related Messages as part of the TPEG2-TEC application. The WEA application provides weather-related forecasts and status information over multiple time periods and for multiple, possibly linked, geographical ar
49、eas. NOTE The presentation of the information is dependent of the specific HMI of the receiving device. This part of ISO/TS 21219, therefore, does not define any prerequisites for the HMI of the device. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
