CEN/TC 278/WG 8 - Road traffic data (RTD)

This document, based on ISO/TS 19468, specifies a platform-specific method for implementing data exchange among centres based on simple object access protocol (SOAP), supporting the EN 16157 series (DATEX II) for Push/Pull data delivery and service request/feedback collaborative intelligent transport system (ITS) services.
This document defines the message rules and procedures for communication between transport information and control systems using XML (Profile B).
This document clarifies how to package end-application messages and relevant data.
The payload data definition used in specific end-applications and the exact structure of the content payload delivered in the messages are beyond the scope of this document.
Rules and procedures for exchanging data-packets in lower communication layers are also out of the scope of this document. These functionalities can be implemented using generic protocols defined in the industry standards. However, this document does define how to use these protocols.

This new work item will revise and extend the sixth part of the DATEX II Technical Specifications which defines three DATEX II parking-related publications and a truck parking profile and that supports the exchange of static as well as dynamic information about parking facilities and areas, including intelligent truck parking as defined by the Directive 2010/40/EU priority action e as well as urban parking as specified in action a.
The formerly used Level B extension will be replaced by a new namespace in the context of version 3.0 of DATEX II.
The publications are intended to support the exchange of informational content from the organisation performing measurements and collecting/eliciting basic data to other organisations providing ITS services or onward information exchange. It is the ambition to harmonise existing information models from different sources such as EasyWay deployment guidelines and truck parking initiatives, and to liaise with the stakeholders involved, especially with the Alliance for Parking Data Standards and CEN/TC 278 working group 3.

This part of the CEN/TS 16157 series specifies details of infrastructure for vehicle energy supply. The provided data model is separated into two publications for static and dynamic information. The static information regarding the infrastructure is not subject to frequent changes, whereas the dynamic part offers the ability to provide highly up-to-date information. The static part covers all relevant information on vehicle energy infrastructure, e.g. sites, stations and refill points for electric vehicles as well as petrol, gasoline or gas-based refuelling for vehicles. In terms of dynamic information, the availability of the infrastructure, possible faults and a price indication are covered.

This document defines and specifies component facets supporting the exchange and shared usage of data and information in the field of traffic and travel.
The component facets include the framework and context for exchanges, the data content, structure and relationships necessary and the communications specifications, in such a way that they are independent from any defined technical platform.
This document establishes specifications for data exchange between any two instances of the following actors:

In order to set up a new technical exchange framework, it is necessary to associate one functional exchange profile with a technical platform providing an interoperability domain where plug-and-play interoperability at a technical level can be expected. The definition of such interoperability domains is out of scope of this document but can be found in other International Standards or Technical Specifications (e.g. the ISO 14827 series).

ISO 14825:2004 specifies the conceptual and logical data model and the exchange format for geographic data bases for Intelligent Transportation System (ITS) applications. It includes a specification of potential contents of such data bases (features, attributes and relationships), a specification of how these contents shall be represented, and of how relevant information about the database itself can be specified (metadata).
The focus of this International Standard is on ITS applications and it emphasizes road and road-related information. ITS applications, however, also require information in addition to road and road-related information.
EXAMPLE 1 ITS applications need information about addressing systems in order to specify locations and/or destinations. Consequently, information about the administrative and postal subdivisions of an area is essential.
EXAMPLE 2 Map display is an important component of ITS applications. For proper map display, the inclusion of contextual information such as land and water cover is essential.
EXAMPLE 3 Point-of-Interest (POI) or service information is a key feature of traveller information. It adds value to end-user ITS applications.

This standard defines the methodology, functions and message structures for the exchange of data between traffic and travel information centres. The normative and informative clauses of the draft have been identified but due to the complexity of the document and cross-referencing the normative and information clauses have not been separated.

This standard defines terms used for data and information in the fields of traffic and travel. The standard is applicable to traffic and transport engineering in general, and particularly data and information exchange. This ENV supersedes ENV 13106-1:1998. The normative terminology is provided in tables 1 to 3. Table 1 provides general definitions; it is normative. Table 2 lists the entities and their instances; it is normative. Table 3 lists the attributes with their definitions, values, units, data type, field width and default format.
