PD CEN/TR 12896-9:2019

What is PD CEN/TR 12896-9 - Reference Data Model for Public Transport Information about?

A Reference data model is an abstract model that organizes Business Information Entities (BIEs) and standardizes how they relate to one another and to the real world. The model provides a standard means by which data may be described, categorized and also shared.

PD CEN/TR 12896 series provides guidelines for implementing data models for public transport systems with a focus on documentation. CEN 12896 series provides a conceptual model of common public transport concepts and data structures that can be used to build many different kinds of public transport information systems, including timetabling, fares, operational management, real-time data, journey planning etc.

PD CEN/TR 12896-9 documents further information related to parts 1 to 8 of version 6 of the "Public Transport – Reference Data Model" (Transmodel v6.0) European Standard, EN 12896.  The various sections of the document provide:

• A Complete Data Dictionary (merging and extending the information contained in each separate Part of the Standard that has been published to date)
• An overview of the whole of Transmodel to provide an understanding of how the model is structured
• An explanation of how each component model links with other components
• An Annex providing a table which shows the evolution of the terms used in Transmodel v6.0 from the previous Transmodel v5.1 and IFOPT European Standards

Who is PD CEN/TR 12896-9 - Reference Data Model for Public Transport Information for?

PD CEN/TR 12896-9  on reference data model for public transport information is useful for those who need additional guidance as regards Transmodel structure and/or intend to implement sub-models. It is also applicable to:

• IT firms involved in public transport data models
• Public transport information system developers
• Public transport authorities
• Public transport experts involved in developing data models

Why should you use PD CEN/TR 12896-9 - Reference Data Model for Public Transport Information?

PD CEN/TR 12896-9 provides a comprehensive conceptual model for public transport information systems including passenger information systems, with coverage of a number of different subdomains of public transport information, including transport network infrastructure and topology, public transport schedules, journey planning, fares, fare validation, real-time passenger information and operational aspects of public transport.

PD CEN/TR 12896-9 establishes a consistent terminology for describing public transport concepts, providing definitive equivalents for use in the National Languages of each participant nation. Where public transport related words in vernacular use may span a number of different concepts and lead to differences of interpretation, it establishes a more precise technical terminology for unambiguous use by public transport information system developers. PD CEN/TR 12896-9 guides you with informative documentation for public transport data models which eventually makes passangers’ travels smoother and safer.
