16、14813-5:2010(E) iv ISO 2010 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 committees. Each me
17、mber 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 the International E
18、lectrotechnical 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 International Standards ad
19、opted 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 the subject of pa
20、tent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14813-5 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems. This first edition of ISO 14813-5 cancels and replaces ISO/TR 14813-5:1999, of which it constitutes a technical rev
21、ision. ISO 14813 consists of the following parts, under the general title Intelligent transport systems Reference model architecture(s) for the ITS sector : Part 1: ITS service domains, service groups and services Part 2: Core TICS reference architecture Technical Report Part 3: Example elaboration
22、Technical Report Part 4: Reference model tutorial Technical Report Part 5: Requirements for architecture description in ITS standards Part 6: Data presentation in ASN.1 BS ISO 14813-5:2010ISO 14813-5:2010(E) ISO 2010 All rights reserved vIntroduction “Architecture” can be defined as “Design; the way
23、 components fit together ”1). Architecture is implicit in any construction, be it of a physical entity (such as a building), an operational entity (such as a company or organisation), a system entity (such as a software system) or a business entity (such as a commercial business operation). While it
24、 may be stated that every entity has an architecture, the particular architecture may be an explicit construction as a result of a deliberate design process or the implicit result of an unplanned series of events, or sometimes the combination of both. In physical construction, it is generally recogn
25、ised that a deliberate design process will produce a better and more efficient building that one where a group of individuals have collected whatever materials happened to be nearby in order to create a shelter. Intelligent transport systems (ITS) are systems deployed in transportation environments
26、to improve both the driving experience and the safety and security of drivers, passengers and pedestrians. ITS can also assist in the labour, energy, environmental and cost efficiency of transportation systems. It is a feature of most ITS that their architecture involves the collection, use and exch
27、ange of information/data within and between software systems which affect or control the behaviour of physical equipment, providing a service to the actors involved in, or interacting with, the transport sector. In order to maximise the efficiency of co-existing ITS, to obtain compatibility and/or i
28、nteroperability and to eliminate contention, the systems need to co-exist and operate within a known and supportive architectural framework. The ITS sector is still emerging and developing and is still close to the start of its evolution and application. The technology is developing and changing rap
29、idly and ITS services have generally to make provision not only for its interaction with other services, but with migration from one technology generation to later iterations. This part of ISO 14813 is designed to ensure that, in order to obtain maximum interoperability, efficiency and migration cap
30、ability, architecture is an explicit process in the development of, and specifications defined within, ITS standards. “Architecture” is used in an informal manner to mean a variety of different concepts and, in formal architecture design, there are differing methodologies and opinions as to their su
31、itability for use in ITS system and standards design. This has limited effective communication in the ITS sector by causing uncertainty as to the meaning of the word when it is used in one context or another. A second function of this part of ISO 14813 is to provide consistent terminology to be used
32、 in describing architectural aspects of ITS standards and provide a consistent form for ITS architecture description in standards in the ITS sector. An ITS architecture is a framework for ITS deployments. It is a high-level description of the major elements and the interconnections among them. It pr
33、ovides the framework around which the interfaces, specifications and detailed ITS designs can be defined. An ITS architecture is not a product design or a detailed specification for physical deployment and is not specific to any one location. “Systems architecture” is perhaps the closest general ter
34、m, but this is sometimes too specific to include the conceptual aspects included in the term “ITS Architecture” and often also implies a location-specific solution. The purpose of an ITS architecture is to maximise efficiency, interoperability and multimodality of multiple interacting ITS in a compl
35、ex and developing sector. 1) Interoperability Clearinghouse Glossary of Terms, http:/www.ichnet.org/glossary.htm) BS ISO 14813-5:2010ISO 14813-5:2010(E) vi ISO 2010 All rights reservedThis part of ISO 14813 does not give preference to any one methodology for architecture development and description.
36、 It requires only that the consideration of architecture be an explicit process that takes into account the interrelationships and interoperability of ITS, and that an architecture description be provided within ITS standards. This part of ISO 14813 requires that the architecture aspects of ITS stan
37、dards be described explicitly in each and every ITS standard, and that all such standards be related to the (one or more) ITS service domains, service groups and services set out in ISO 14813-1 that they are designed to enable or support.

38、 ISO 2010 All rights reserved 1Intelligent transport systems Reference model architecture(s) for the ITS sector Part 5: Requirements for architecture description in ITS standards 1 Scope This part of ISO 14813 gives requirements for the description and documentation of the architecture of intelligen
39、t transport systems (ITS) in standards dealing with ITS. It also defines the terms to be used when documenting or referencing aspects of architecture description in those standards (see Annex B). Although the use of contemporary systems engineering practices is assumed by this part of ISO 14813, it
40、does not define such practices. NOTE Guidance on the use of the unified modelling language (UML) in ITS architectures can be found in ISO/TR 17452 and ISO/TR 24529. Guidance on the use of the process-orientated methodology in ITS architectures can be found in ISO/TR 26999. 2 Conformance There are no
41、 specific conformance tests specified within or associated with this part of ISO 14183. Developers of standards claiming conformance with this part of ISO 14183 are, however, required to describe the architecture of their system in their deliverables, or to make reference to other standards or publi
42、cly available documents that provide such description. The level of detail or the methodology used for such description is not specified and is left to the discretion of the standards developers. Implementers of ITS cannot, of course, be required to make such provision, but are advised to do so in t
43、heir plans and tender documents. This part of ISO 14813 is therefore also designed as a consistent reference for ITS system designers. 3 Normative references The following referenced documents are indispensable for the application of this document.
