13、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

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop t

20、ral requirements and conceptual model Part 2: Pre-coded location references (pre-coded profile) Part 3: Dynamic location references (dynamic profile)iv ISO 2015 All rights reservedBS ISO 17572-2:2015ISO 17572-2:2015(E)IntroductionA location reference (LR) is a unique identification of a geographic o

21、bject. In a digital world, a real-world geographic object can be represented by a feature in a geographic database. An example of a commonly known location reference is a postal address of a house. Examples of object instances include a particular exit ramp on a particular motorway, a road junction,

22、 or a hotel. For efficiency reasons, location references are often coded. This is especially significant if the location reference is used to define the location for information about various objects between different systems. For intelligent transport systems (ITS), many different types of real-wor

23、ld objects will be addressed. Amongst these, location referencing of the road network, or components thereof, is a particular focus.Communication of a location reference for specific geographic phenomena, corresponding to objects in geographic databases, in a standard, unambiguous manner is a vital

24、part of an integrated ITS system in which different applications and sources of geographic data will be used. location referencing methods (LRMs, methods of referencing object instances) differ by applications, by the data model used to create the database, or by the enforced object referencing impo

25、sed by the specific mapping system used to create and store the database. A standard location referencing method allows for a common and unambiguous identification of object instances representing the same geographic phenomena in different geographic databases produced by different vendors, for vari

26、ed applications, and operating on multiple hardware/software platforms. If ITS applications using digital map databases are to become widespread, data reference across various applications and systems has to be possible. Information prepared on one system, such as traffic messages, has to be interpr

27、etable by all receiving systems. A standard method to refer to specific object instances is essential to achieving such objectives.Japan, Korea, Australia, Canada, the US, and European ITS bodies are all supporting activities of location referencing. Japan has developed a Link Specification for VICS

28、. Japan has developed the Road Section Identification Data set which uses road sections and reference points after the publication of the first edition of this part of ISO 17572 in 2008. In Europe, the RDS-TMC traffic messaging system has been developed. In addition, methods have been developed and

29、refined in the EVIDENCE and AGORA projects based on intersections identified by geographic coordinates and other intersection descriptors. In the US, standards for location referencing have been developed to accommodate several different location referencing methods.This International Standard provi

30、des specifications for location referencing for ITS systems (although other committees or standardization bodies can subsequently consider extending it to a more generic context). In addition, this edition does not deal with public transport location referencing; this issue will be dealt with in a l

31、ater edition.

32、) that describe locations in the context of geographic databases and will be used to locate transport-related phenomena in an encoder system as well as in the decoder side. This International Standard defines what is meant by such objects and describes the reference in detail, including whether or n

33、ot components of the reference are mandatory or optional, and their characteristics.This International Standard specifies two different LRMs: pre-coded location references (pre-coded profile); dynamic location references (dynamic profile).This International Standard does not define a physical format

34、 for implementing the LRM. However, the requirements for physical formats are defined.This part of ISO 17572 specifies the pre-coded location referencing method, comprising specification of pre-coded location references (pre-coded profile), logical format for VICS link location (see Annex A), TPEG p

35、hysical format for ALERT-C-location references (see Annex B, Annex C, and Annex D), TPEG physical format for Korean node-link ID references (see Annex E, Annex F, and Annex G), and logical format for Road Section Identification Data set (see Annex H).Logical formats of the implementations at present

36、 are described as informative; on the other hand, physical formats of the implementations at present are described as normative in the annexes.It is consistent with other International Standards developed by ISO/TC 204 such as ISO 14825.2 Normative referencesThe following documents, in whole or in p

44、 database (LDB) that is exactly the same as the corresponding location database used by a service provider of a particular message being exchanged. All pre-coded location referencing methods shall share the concept of defining a commonly used database of IDs. This concept has been developed in the p

45、ast for technologies such as RDS-TMC and VICS to allow an (over-the-air) interface to be designed that uses compact code values (IDs) in the corresponding databases to express particular pre-coded locations of various types.The location referencing method here is divided into three steps performed t

46、o implement the location referencing system. The first step is a process of defining the database of location IDs for a given area and the corresponding road network. In this step, different service providers and systems provider agree on a defined database containing all locations to be codable (lo

47、cation database creation). In the second step, this database is provisioned via various means into the service providers database as well as into all receiving systems (location database provisioning). The third step is in real-time where a service provider can now make use of that database and refe

48、rence to locations by using the newly introduced IDs (location database usage). See Figure 1, which illustrates this concept.Figure 1 General concept of pre-coded location referencing system ISO 2015 All rights reserved 3BS ISO 17572-2:2015ISO 17572-2:2015(E)7.2 Location database creation and updati

49、ngThe different location referencing systems more or less support standardized ways to create a new release of a location database. All of them share a conceptual model specifying how the different location categories specified in ISO 17572-1 are related to each other. This specification, together with some guiding literature, helps the community to create new releases of the location database.7.3 Location database provisionAfter finalization of the creation process, the newly created location database is provisioned into the
