It should be applied on thisprovisional basis, so t

A review of this publ

Notification of the start of the review period will be made inan announcement in the appropriate issue of Update Standards.According to the replies rec

6、eived by the end of the review period,the responsible BSI Committee will decide whether to support theconversion into an international Standard, to extend the life of theTechnical Specification or to withdraw it.

Attention is drawn to the possi

23、bility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes ENV 13106:2000, ENV 13777:2000. As a user of the standard, attention is drawn to the resourc

24、es of www.datex2.eu. This web site contains related software tools and software resources that aid the implementation of CEN/TS 16157 DATEX II.

DD CEN/TS 16157-1:2011CEN/TS 16157-1:2011 (E) 5 Introduction This Technical Specification defines a common set of data exchange specifications to support the vision of a seamless interoperable exchange of traffic and travel information across boundaries, including national, urban, int

27、erurban, road administrations, infrastructure providers and service providers. Standardisation in this context is a vital constituent to ensure interoperability, reduction of risk, reduction of the cost base, promotion of open marketplaces and many social, economic and community benefits to be gaine

28、d from more informed travellers, network managers and transport operators. Delivering European Transport Policy in line with the White Paper issued by the European Commission requires co-ordination of traffic management and development of seamless pan European services. With the aim to support susta

29、inable mobility in Europe, the European Commission has been supporting the development of information exchange mainly between the actors of the road traffic management domain for a number of years. In the road sector, DATEX II has been long in fruition, with the European Commission being fundamental

30、 to its development through an initial contract and subsequent co-funding through the Euro-Regional projects. With this standardisation of DATEX II there is a real basis for common exchange between the actors of the traffic and travel information sector. This Technical Specification includes the fra

31、mework and context for exchanges, the modelling approach, data content, data structure and relationships, communications specification. This Technical Specification supports a methodology that is extensible. The European Committee for Standardisation (CEN) draws attention to the fact that it is clai

32、med that compliance with this document may involve the use of a patent concerning procedures, methods and/or formats given in this document. CEN takes no position concerning the evidence, validity and scope of patent rights. This document (i.e. CEN/TS 16157-1) is targeted towards all stakeholders th

33、at want to understand the modelling methodology applied throughout the DATEX II specifications. While this is potentially a wide range of readers, the document addresses specifically those users that intend to extend the DATEX II data model and therefore need to understand and comply with the modell

34、ing principles, the use of the “Unified Modeling Language” (UML) and other conventions for DATEX II modelling. The subject matter may be difficult to address without some basic background about the historical evolution and main design decisions taken. Users unfamiliar with this background may find a

35、 brief summary in Annex A. Users not (yet) familiar with the UML find a brief introduction in the informative Annex B. Further to the UML modelling, this Technical Specification also defines the mapping of this model to the “eXtensible Markup Language” (XML), used for formatting data in DATEX II dat

36、a exchanges. XML is the most widely used method nowadays of formatting data for business-to-business data exchange (i.e. centre-to-centre) over the Internet. DD CEN/TS 16157-1:2011CEN/TS 16157-1:2011 (E) 6 1 Scope This Technical Specification (CEN/TS 16157-1) specifies and defines component facets r

37、equired to support the exchange and shared use of data and information in the field of traffic and travel. The component facets include the framework and context for exchanges, the modelling approach, data content, data structure and relationships, communications specification. This Technical Specif

38、ication is applicable to: traffic and travel information which is of relevance to road networks (non urban and urban); public transport information that is of direct relevance to the use of a road network (e.g. road link via train or ferry service). This Technical Specification establishes specifica

39、tions for data exchange between any two instances of the following actors: Traffic Information Centres (TICs); Traffic Control Centres (TCCs); Service Providers (SPs). Use of this Technical Specification may be applicable for use by other actors. This Technical Specification covers, at least, the fo

40、llowing types of informational content: road traffic event information planned and unplanned occurrences both on the road network and in the surrounding environment; operator initiated actions; road traffic measurement data, status data, and travel time data; travel information relevant to road user

41、s, including weather and environmental information; road traffic management information and information and advice relating to use of the road network. This part of CEN/TS 16157 specifies the DATEX II framework of all parts of this Technical Specification, the context of use and the modelling approa

42、ch taken and used throughout these Technical Specifications. This approach is described using formal methods and provides the mandatory reference framework for all other parts. 2 Conformance This document provides requirements for UML models (as of ISO/IEC 19501:2005) that claim conformance with the

43、 DATEX II Technical Specifications. UML models claiming this conformance shall comply with the provisions of the normative clauses and annex of this part. Conformance with metadata constructs is subject to multiplicity requirements stated explicitly in the model or is implicitly defined in provision

44、s of this Technical Specification. Metadata constructs with minimum multiplicity of 1 or more shall be present in any data claiming conformance. Metadata constructs with minimum multiplicity of 0 may be present or may be missing without violating conformance. DD CEN/TS 16157-1:2011CEN/TS 16157-1:201
