CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes ENV 13777:2000,

This web site contains related software tools and software resources that aid the implementation of CEN/TS 16157 DATEX II. According to the CEN/CENELEC Internal Regulations, the national standards organ

DD CEN/TS 16157-2:2011CEN/TS 16157-2:2011 (E) 5 Introduction This Technical Specification defines a common set of data exchange specifications to support the vision of a seamless interoperable exchange of tra
34、ffic and travel information across boundaries, including national, urban, interurban, 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 o
35、pen marketplaces and many social, economic and community benefits to be gained 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
36、 development of seamless pan European services. With the aim to support sustainable 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
37、 II has been long in fruition, with the European Commission being fundamental 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 traffi
38、c and travel information sector. This Technical Specification includes the framework and context for exchanges, the modelling approach, data content, data structure and relationships, communications specification. This Technical Specification supports a methodology that is extensible. This Part, Par
39、t 2 of this Technical Specification, deals with DATEX II location referencing. It references existing location referencing Standards or Technical Specifications. The European Committee for Standardisation (CEN) draws attention to the fact that it is claimed that compliance with this document may inv
40、olve 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. DD CEN/TS 16157-2:2011CEN/TS 16157-2:2011 (E) 6 1 Scope This Technical Specification (CEN/TS 16157-2) specifies and defin
41、es component facets supporting 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 Tech
42、nical Specification 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 establish
43、es specifications 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 l
44、east, the following 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
45、to road users, including weather and environmental information; road traffic management information and instructions relating to use of the road network. This part of the CEN/TS 16157 specifies the informational structures, relationships, roles, attributes and associated data types, for the implemen
46、tation of the location referencing systems used in association with the different publications defined in the Datex II framework. It also defines a DATEX II publication for exchanging predefined locations. This is part of the DATEX II platform independent data model. 2 Conformance The DATEX II platf
47、orm independent data model of which the location referencing packages as well as Predefined Locations Publication sub-model are parts, corresponds to the Level A model as defined in CEN/TS 16157-1. Conformance with this Part shall require platform independent models from which platform specific mode
48、ls are generated to comply with the UML modelling rules defined in CEN/TS 16157-1 and with the following requirements of this sub-model which are expressed in this Part: DD CEN/TS 16157-2:2011CEN/TS 16157-2:2011 (E) 7 comply with all stipulated minimum and maximum multiplicity requirements for UML e
49、lements and relationships; comply with all definitions, types and ordering; employ optional elements as specified; comply with all expressed constraints. It should be noted that conformance of a publication service with all the structural requirements stated above does not necessarily ensure that the informational content of that service wil
