9、word 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 which a techn

10、ical 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 matters of

11、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 adopted by the technical committees are circulated to

12、 the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an International St

13、andard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid or usefu

15、 24098:2007(E) ISO 2007 All rights reserved v Introduction This Technical Report was developed by ISO/TC 204, WG 1, Architecture, in order to provide a procedure for developing Intelligent Transport System (ITS) deployment plans utilizing ITS system architectures. It is well perceived in the ITS com

16、munity that understanding the system architecture is significant for the realization of ITS, which extends over wide areas on service domains, system sizes, and relating stakeholders and users. Those who deploy ITS systems within a specific region need to consider the coverage area, as well as exist

17、ing inventories. This Technical Report facilitates the introduction of ITS at regional levels through the development of the ITS deployment plans by utilizing regional ITS architectures. Examples of ITS deployment guidelines are given in Annex A. TECHNICAL REPORT ISO/TR 24098:2007(E) ISO 2007 All ri

NOTE 2 In an object-oriented perspective, a logical architecture elaborates the conceptual behaviour and in so doing defines some detail of the objects. In a process-oriented perspective, the logica

The logical architecture is independent of any hardware or software approach. 3

The target is realization of regional ITS systems and provi

32、sion of ITS services to the users by the collaboration of subsystems that are implemented by relevant ITS stakeholders. An ITS deployment plan for a region will make the efficient implementation through the intelligible accountability and the consensus among the regional stakeholders. The plan is us

33、ed for obtaining a budget for deployment, for designing the regional ITS systems, and for promoting the deployment and operation of the systems within the region. ISO/TR 24098:2007(E) ISO 2007 All rights reserved 3Figure 1 Framework of regional ITS deployment 5.2 National ITS architecture There are

34、several ways in which a national ITS architecture can be used to create ITS deployment plans. These are illustrated in Figure 2. Figure 2 Relationship between regional and national ITS deployments The example in Figure 2 enables interoperability between the ITS systems deployed at nearby regions, as

35、 well as within the target region itself. ISO/TR 24098:2007(E) 4 ISO 2007 All rights reserved6 The procedure for developing ITS deployment plans 6.1 Framework A national architecture covers overall ITS services within a nation and this may be what is needed for some ITS deployments. However, a regio

36、nal architecture may be needed when only some of the ITS services within the national architecture are required. In order to realize sustainable ITS within a region or nation, it is necessary to identify the ITS services that are required, to establish subsystems by dividing roles among ITS-related

37、stakeholders, and to keep a close liaison between those stakeholders. To achieve this, it is necessary to prepare ITS deployment plans based on the regional or national ITS architecture. These plans will illustrate the division of roles and coordination between ITS stakeholders. Based on these plans

38、, it will be possible to negotiate and secure budgets and establish operational systems at the stakeholder level. 6.2 Procedure The procedure for developing an ITS deployment plan for a region or nation should be the following. Identify the appropriate ITS stakeholders and gain their cooperation and

39、 participation. With the stakeholders, define the ITS services that they want to see deployed. Describe the ITS physical system structure that is needed to provide the services. Define and agree upon the stakeholders roles for the ITS deployment. 6.2.1 Identifying the participation of appropriate IT

40、S stakeholders It is essential that the scope of the regional (or national) ITS architecture, and the identification and participation of the ITS stakeholders involved in the development process, are determined and agreed. The mobility of residents in daily activities should be taken into account (e

41、.g. commuting, shopping and business). The geographic coverage of the ITS architecture will depend on the area of jurisdiction belonging to its owners. Thus, regional ITS architecture may cover one or more metropolitan regions and transport infrastructures between them, and a city ITS architecture m

42、ay cover one city. The area where the stakeholders involved in the ITS development operate or administer should also be taken into consideration. However, the need for a regional ITS architecture should also depend on how much of the national ITS architecture it will include. Stakeholders involved i

43、n the development of the ITS architecture should include organizations that fit into one or more of the following types. These types should include those stakeholders that: want ITS: these will be local authorities that manage the highways, and road operators that will want ITS to improve the operat

44、ion of their transport networks; make ITS: these will be organizations that are component and system suppliers and/or infrastructure providers that will see ITS as providing them with extra business opportunities; use ITS: these will be travellers, pedestrians, PT passengers, plus those that move fr

45、eight; all of whom hope that ITS will improve the ways that they can travel; rule ITS: these will be organizations such as national and regional governments and standards bodies that regulate and control the way that ITS is deployed and implemented.

46、5 A broad range of stakeholders of several of the above types may exist within the area in which ITS is to be deployed. It is also important for any stakeholders whose existence is recognized during the ITS architecture development process be asked to participate, as appropriate. It is important to

47、ensure that outreach to the ITS stakeholders gains commitment to the usefulness and significance of the ITS architecture in the process of establishing the ITS systems that need to be deployed to provide the services. It is useful to nominate a leading stakeholder, sometimes called the “architecture

48、 champion” to urge all the stakeholders to participate positively in the establishment of the ITS systems. The leading stakeholder will normally review the area covered by the ITS architecture to be developed and identify the stakeholders participating in the development process. 6.2.2 Defining ITS

49、services Services to be provided within the area of the ITS deployment should be based on local issues and needs for transportation. The services that are required are normally selected from the list of ITS services described in the national ITS architecture or the framework ITS architectures that are to be adopted. Consideration must be allowed for the services currently existing in the region to be incorporated into the ITS architecture and the resulting ITS deployment. Issues arising in the area of
