Transmodel

Transmodel (formally CEN TC278, Reference Data Model For Public Transport, EN12896 ) is the CEN European Reference Data Model for Public Transport Information; It provides an abstract model of common public transportation concepts and data structures That can be used to build Many different kinds of public transport information system , Including for timetabling, fares, operational management, real time data, journey schedule etc.

Scope

Transmodel Provides a comprehensive conceptual model for public transport (PT) Information Systems Including passenger information systems , with coverage of a number of different subdomains of PT Information, Including transportation network infrastructure and topology , public transport schedules, journey schedules , fares, fare validation, Real-time passenger information and operational aspects of public transport .

  • It is documented and diagrammed as an entity-relationship model and in Unified Modeling Language (UML), accompanied by detailed descriptions of the concepts, elements and attributes needed to represent transport information.
  • It is a matter of fact that,
  • It makes extensive use of node and link concepts to describe individual transport information layers.
  • It supports the reuse of transport information entities for different applications.
  • It can represent multi-modal, multi-operator transport systems, with many different organizational structures, complex fare models, and different organizational practices.

Transmodel establishes a consist terminology for public transportation concepts, providing definitive equivalents for use in the National Languages ​​of each participant nation. Where PT is concerned, it is possible to use the term PT information system to describe the PT system. For example the terms ‘trip’, ‘journey’, ‘service’, are overlapping concepts that in Transmodel are used only in a more specific uses.

The current when? ] Version of Transmodel is 5.1 with a 6.0 in draft.

History

Transmodel Was Originally Developed Within a Range of European projects of Several European programs (Drive I-Drive II TAP) with the backing of the European Commission (DG XIII), and national public institutions, In Particular of the French Ministry of Transport (Directorate Terrestrial Transport) and private companies.

  • Transmodel development started with the Cassiope project (1989-1991, Drive I program). The results of Cassiope were then further developed by the EuroBus and Harpist (Drive II) projects. This produced Transmodel V4.1 ENV 12896 with a “Oracle” formalism.
  • The Telematics Applications Program TITAN (1996-1998) Transmodel implementing it in three Transmodel V5. 0: with multi-modality, real-time control, layers, and data versioning
  • SITP : Information System for Public Transport, launched in 1999 under the sponsorship of the French Ministry of Transport , which supports the Transmodel site. SITP developed Transmodel V5.1, adding a UML formalism.
  • NeTEX : (NETwork EXCHANGE) is a concrete XML scheme implementing the central components of the Transmodel model as a modular W3C schema. It was developed as a CEN Technical Standard by CEN WG278 SG9 between 2009 and 2014 CEN as a European wide format for exchanging intermodal stop, timetable and fare data for public transport.

More recently Transmodel has-been Fundamental to the development of a number of concrete national data models and European Standards, Including TransXChange (2001-2005 now the UK standard for bus timetables), Trident (1999-2003), Service Interface for Real Time Information ( SIRI: 2001-2005, now a CEN technical specification) for Real-time data exchange for buses, and Identification of Fixed Objects in Public Transport (2006-2007). Its provision of a uniform conceptual framework, consisting of terminology and well grounded abstractions, make it valuable for harmonizing and modernizing legacy standards and systems for international cooperation.

In 2006 version 5.1 of Transmodel was formally adopted by CEN as a European standard, EN12896.
