26、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 right to be represent
27、ed 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. International Standards are dra
28、fted 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 an International St
29、andard 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 Available Specification (I
30、SO/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 members of a techni
31、cal 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 Standard, or withdra
32、wn. 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again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn.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 subject of patent right
33、s. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TS 14822-1 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 278, Road transport and traffic telematics, in collaboration with Technical Committee ISO/TC 204, Intelligent
34、 transport systems, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). ISO/TS 14822 consists of the following parts, under the general title Traffic and Travel Information General specifications for medium-range pre-information via dedicated short-range
35、 communication: Part 1: Downlink DD CEN ISO/TS 14822-1:2006vIntroduction Traffic and Travel Information may be disseminated through a number of services or means of communication, covering static displays, portable terminals and in-vehicle equipment. For all such services the data to be disseminated
36、, and message structure involved in the various interfaces, require clear definition and standard formats in order to allow competitive products to operate with any received data. This Technical Specification focuses on the application data specification whereby data are produced at a central locati
37、on and disseminated via a network of Dedicated Short-Range Communication (DSRC) beacons. This part of ISO 14822 addresses the data specifications for the downlink data flows between a central location and moving vehicles passing a predetermined location. ISO 14822-2 addresses the data specification
38、for the uplink data flows that emanate from a moving vehicle, passing a predetermined location, to a central location. In order to facilitate all the demands of ISO 14822-2, four bytes in the downlink message are reserved for the beacon to insert the date/time stamp of the download. Due to the need
39、for the in-station to generate message CRCs, these bytes are not included in the header CRC. Other documents are being produced by the CEN/TC 278 Working Group 4 and ISO/TC 204 Working Group 10 to cover TTI dissemination via other communication means and services. This Technical Specification specif
40、ies the application protocols and message structures for delivering Medium Range Pre Information (MRPI) as accepted within CEN TC 278 for Traffic and Travel Information (TTI) via Dedicated Short Range Communication (DSRC) devices. DSRC has specific characteristics that differentiate this communicati
41、on medium from other communication media envisaged for traffic and traveller information, i.e. RDS-TMC (and later DAB) and GSM. These characteristics are: bi-directional communication, which is useful for collecting information/data from the vehicle or perhaps selecting vehicles for a particular dia
42、logue; and spot communication, i.e. communications that can only take place at a precise point. This is a particularly important characteristic. The communication zone does not exceed some 10 m or 20 m in front of the beacon. At the time of communication, the position of the vehicle is accurately kn
43、own, not only in terms of geographical localization (i.e. comparable to what can be obtained with a GPS receiver) but in terms of road and travel direction on this road. This localization feature is used beyond the communication zone. By combining initial location information with information from t
44、he vehicles speed sensor or odometer, the position of the vehicle is known with great accuracy for several kilometres and reasonable accuracy for tens of kilometres. Location information is updated when the vehicle passes the next beacon, probably at the next junction. This may be a small distance i
45、n urban areas or a large distance on motorway or expressway networks. This part of ISO 14822 describes the application protocol, data definitions and message structures for each MRPI service defined. It forms part of a series of Technical Specifications defining the framework of a DSRC link in the R
46、oad Transport Traffic Telematics (RTTT) environment. The communication requirements of many RTTT applications can be fulfilled by DSRC. The DSRC International Standards enable compliant communication systems to serve multiple RTTT application in parallel. This Technical Specification deals with the
47、Application layer only. DD CEN ISO/TS 14822-1:2006vi CEN has issued the following set of European Standards for the DSRC link: EN 12253 Road transport and traffic telematics Dedicated short-range communication Physical layer using microwave at 5,8 GHz; EN 12795 Road transport and traffic telematics
