EN 16157-2:2019 (E) 5 Introduction This European Standard 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, interurban, road administrations, infrastructure providers and service providers. Standardization 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 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 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 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 standardization of DATEX II, there is a real basis for common exchange between the actors of the traffic and travel information sector. This European Standard includes the framework and context for exchanges, the modelling approach, data content, data structure and relationships. This European Standard supports a methodology that is extensible. This part of EN 16157 deals with DATEX II location referencing. It references existing location referencing Standards or European Standards. SIST EN 16157-2:2019



EN 16157-2:2019 (E) 6 1 Scope This European Standard series (EN 16157) specifies and defines 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. This European Standard series 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), — traffic and travel information in the case of Cooperative intelligent transport systems (C-ITS). This European Standard series establishes 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 European Standard series may be applicable for use by other actors. This European Standard series covers, at least, 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 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 EN 16157 series specifies the informational structures, relationships, roles, attributes and associated data types, for the implementation 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. SIST EN 16157-2:2019
