19、ion 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 which a technical committee has been established h
20、as 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 matters of electrotechnical standardization. Int
21、ernational 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. Public
22、ation 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 other types of document: an ISO Publicly Availabl
23、e 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 m
24、embers 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 St
25、andard, or withdrawn.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again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn.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 subje

27、 are being investigated and deployed throughout the world. It is expected that the number of practical systems will grow steadily over the next few years. Since communications airtime will always be a scarce and expensive commodity, efficient probe data reporting systems must rely on techniques to u
28、se airtime efficiently and economically. One way to accomplish this is to have the probe processing center guide the economic collection of necessary probe information by sending reporting management instructions to probe vehicles, that is probe data reporting management (PDRM). As probe vehicle sys
29、tems have to collect and manage probe data from a variety of vehicles from different vehicle manufacturers, the standardization of these reporting management instructions is essential. To do this, a common framework for PDRM is also required. This Technical Specification helps system developers and
30、operators to specify efficient probe data collection and processing systems; it also promotes communication and mutual understanding among the developers and the operators of probe vehicle systems, and helps system developers who are developing probe vehicle systems to define a key tool for communic
31、ations-efficient probe vehicle systems, i.e. PDRM. This Technical Specification also provides a) a reference architecture for PDRM within an architecture which encompasses both this function and PDRM defined in ISO 22837, b) the basic data framework for defining PDRM instructions, and c) the concret
32、e definition of these instructions. PDRM enables a landside probe processing center to issue requests to probe vehicles to optimize probe data reporting. A preliminary set of management instructions for PDRM are defined which support selective probe data reporting and the efficient use of communicat
33、ions airtime. A reference model is provided which incorporates the reference model of ISO 22837, vehicle probe data for wide area communications, and also encompasses PDRM aspects.

34、stems Probe data reporting management (PDRM) 1 Scope This Technical Specification provides a common framework for defining probe data reporting management (PDRM) messages to facilitate the specification and design of probe vehicle systems and gives concrete definitions of PDRM messages. This Technic
35、al Specification specifies a) reference architecture for probe vehicle systems and probe data which incorporates PDRM based on the reference architecture for ISO 22837, and b) basic data framework for PDRM instructions, which defines specifically 1) necessary conditions for PDRM instructions, and 2)
36、 notations of these instructions (in XML). This Technical Specification also provides the rules for using PDRM instructions. Different types of PDRM messages are also identified and defined, such as a) PDRM messages consisting of individual instructions which define reporting aspects or requirements
37、 for probe vehicle systems, b) start/stop all probe data reporting, c) start/stop probe data reporting of specific probe data elements, and d) generic scheme for conveying criteria for reporting specific probe data elements. PDRM instructions may be structured in terms of a time period in which they
38、 are valid (duration), geographic region, and roadway heading to which the instruction applies.
