13、 ISO 22837:2009ISO 22837:2009(E) iv ISO 2009 All rights reservedForeword 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 co
14、mmittees. Each member body interested in a subject for which 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 th
15、e International Electrotechnical Commission (IEC) on all 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 Internati
16、onal Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be
17、the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22837 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems. BS ISO 22837:2009ISO 22837:2009(E) ISO 2009 All rights reserved vIntroduction This International Sta
18、ndard specifies the core and initial sets of probe data elements and example probe messages, and a framework for defining and extending these probe data elements and probe messages. It facilitates the development and operation of probe vehicle systems by providing a standard set of probe data elemen
19、ts and probe messages along with the basic data framework to extend the set. This International Standard provides a reference architecture for probe vehicle systems and for probe data, a basic data framework for probe data elements and probe messages, the definition of core data elements, the defini
20、tion of an initial set of additional probe data elements, and the definition of example probe messages. This International Standard facilitates the work of system developers and operators who need to specify probe data elements and probe messages: There are many ways that probe data elements and pro
21、be messages could be defined. This International Standard provides a concrete and common way to define probe data elements and probe messages. The standard also facilitates communication and mutual understanding among the developers and the operators of probe vehicle systems. The ability to develop
22、probe vehicle systems in a consistent and uniform manner reduces development time and cost. If a particular probe vehicle system requires additional probe messages that are not yet part of the standard, the existence of a common framework for defining probe data elements/messages helps system develo
23、pers to develop probe vehicle systems in a uniform way. Probe data will be collected from many vehicle makes and models from many vehicle manufacturers. This standard provides a basic data framework for handling probe data elements/messages and the concrete definition of major probe data components
24、that help collect and process probe data consistently. It should be noted that this International Standard does not prescribe a physical communication medium for transmitting probe messages to or from vehicles. This International Standard is intended to be independent of any particular communication
25、 medium and to be compatible with any medium that is selected by system developers. Core data elements and normative probe data elements are covered in Clauses 7 and 8 respectively. Subclause 5.3 and Annex A are of interest to users familiar with information modelling. BS ISO 22837:2009BS ISO 22837:
26、2009INTERNATIONAL STANDARD ISO 22837:2009(E) ISO 2009 All rights reserved 1Vehicle probe data for wide area communications 1 Scope This International Standard specifies the following. Reference architecture for probe vehicle systems and probe data. This reference architecture provides a general stru
27、cture for probe vehicle systems within which a wide range of actual probe vehicle systems can be built whose physical characteristics may differ (e.g., in their choice of communications medium). The reference architecture is used to: clarify the major building blocks and logical interconnections of
28、probe vehicle systems for which this standard will be used; categorize probe data in accordance with the information model described below. Basic data framework for probe data elements and probe data. This framework specifies how to define probe data elements and probe messages. Specifically it prov
29、ides the following. Rules for mapping information models (as defined in ISO 14817) of probe data to probe data elements/messages. The information models show the logical structure of entities and concepts involved in probe data. Required characteristics of probe data elements and probe data messages
30、 The notation for probe data elements/messages (in XML). Rules for using core data elements and basic data elements (see below), and extensions of data elements in each application domain. Core data element definitions. Core data elements are basic descriptive elements intended to appear in every p
31、robe message. These are the location and the time at which the probe data was sensed. Initial set of probe data elements. These elements will be commonly used in typical probe data enabled application domains, such as traffic, weather, and safety. Standardizing these probe data elements facilitates
32、the development of probe vehicle systems and the distribution of probe data. This is not intended to be an exhaustive listing of probe data elements. Example probe messages. These messages define how probe data elements are combined to convey information to probe processing centres. This is not inte
33、nded to be an exhaustive listing of probe messages. Figure 1 depicts the scope described above.

35、lizerefersFigure 1 Scope of this International Standard To completely define probe processing, the standardization of probe data elements and probe messages is not sufficient. Standards are also required for processed probe data (the output of probe processing) and downlink elements and messages (to
36、 convey these results to vehicles and other users). This International Standard prescribes an initial set of probe data elements that are important for transmission from vehicles to land-side processing centres. The standardization of other probe data issues will be addressed in future work. 2 Confo
37、rmance Conforming probe data elements shall be defined based on the basic data framework. Conforming probe messages shall be defined based on the basic data framework, and include core data elements among its members. Conforming systems do not need to use all probe data elements in this Internationa
38、l Standard. Developers of probe systems may define probe data elements in addition to those listed in the normative portion of this International Standard as extensions. Parties who create extensions to the standard should be cautioned, however, that probe data elements defined outside of this Inter
39、national Standard may not be recognized by all probe data processing centres.
