Transmodel

Transmodel, also known as Reference Data Model For Public Transport (EN 12896), is a European Standard for modelling and exchanging public transport information. It provides a standard data model and specialised data structures to uniformly represent common public transport concepts, facilitating the use of data in a wide variety of public transport information systems, including for timetabling, fares, operational management, real-time data, and journey planning. As of 2021, the current version of Transmodel is 6.0.

Transmodel, also known as Reference Data Model For Public Transport (EN 12896), is a European Standard for modelling and exchanging public transport information. It provides a standard data model and specialised data structures to uniformly represent common public transport concepts, facilitating the use of data in a wide variety of public transport information systems, including for timetabling, fares, operational management, real-time data, and journey planning. As of 2021, the current version of Transmodel is 6.0. ==Scope== Transmodel provides a comprehensive conceptual model for public transport information systems, covering multiple subdomains including transport network infrastructure and topology, schedules, journey planning, fares, fare validation, real-time passenger information, and operational systems. Transmodel is an entity-relationship model in Unified Modeling Language (UML), accompanied by detailed descriptions of the concepts, elements and attributes needed to represent transport information. It uses modern information architecture principles to separate different concerns into independent information layers, using node and link concepts to describe individual transport layers. It supports the reuse of transport information entities for different applications. It can represent multi-modal, multi-operator transport systems and complex fare models, bringing together data from many different organisations with different standard and practices. The Transmodel standard also establishes consistent terminology for public transport concepts, providing definitive equivalents for use in the national languages of each participant nation. In cases where vernacular words related to public transport could have more than one possible meaning or overlap in meaning, it establishes a precise and unambiguous technical term for use in information systems. For example, the terms 'trip', 'journey', and 'service', are overlapping concepts that in Transmodel have specific usages. ==History== Transmodel was originally developed within a range of European projects under several European Programmes (Drive I, Drive II, TAP) with the support of the European Commission (DGXIII), and national public institutions, in particular the French Ministry of Transport (Direction des Transports Terrestres), as well as several private companies. ===Initial development & first generation uses=== Transmodel originated in the Cassiope project (Computer Aided System for Scheduling Information and Operation of Public Transport in Europe, 1989-1991), carried out under the initial EEC DRIVE programme. The results of Cassiope were then developed further by the EuroBus and Harpist (Drive II) projects. This produced Transmodel V4.1 ENV 12896 with a E/R “Oracle” formalism. The Telematics Applications Programme project TITAN (1996-1998) continued to validate and enhance Transmodel, implementing it in three European pilot sites. TITAN accompanied the standardisation process of Transmodel, which was chosen in 1997 as the European Experimental Norm ENV 12896. This led to Transmodel V5.0: with multi-modality, real-time control, layers, and data versioning The Système d'Information pour le Transport Public (SITP) (Information System for Public Transport), which began in 1999 under the sponsorship of the French Ministry of Transport, developed Transmodel 5.1, adding a UML formalism. In 2006, version 5.1 of Transmodel was formally adopted by the European Committee for Standardization (CEN) as the European Standard EN 12896. ==See also== TransXChange Transport Direct Transport standards organisations NeTEx Identification of Fixed Objects In Public Transport (IFOPT) Service Interface for Real Time Information (SIRI) NaPTAN (UK) ==References== ==Bibliography== Comité Européen de Normalisation (CEN), Reference Data Model For Public Transport, EN12896 EN 12896:2006, Public Transport Reference Data Model (“Transmodel v5.1”) EN 12896-1:2016, Public Transport Reference Data Model - Part 1: Common Concepts (“Transmodel v6”) EN 12896-2:2016, Public Transport Reference Data Model - Part 2: Public Transport Network (“Transmodel v6”) EN 12896-3:2016, Public Transport Reference Data Model - Part 3: Timing Information and Vehicle Scheduling (“Transmodel v6”) EN 12896-4:2019, Public Transport Reference Data Model – Part 4: Operations Monitoring and Control (“Transmodel v6”) EN 12896-5:2019, Public Transport Reference Data Model – Part 5: Fare Management (“Transmodel v6”) EN 12896-6:2019, Public Transport Reference Data Model – Part 6: Passenger Information (“Transmodel v6”) EN 12896-7:2019, Public Transport Reference Data Model – Part 7: Driver Management (“Transmodel v6”) EN 12896-8:2019, Public Transport Reference Data Model – Part 8: Management Information & Statistics (“Transmodel v6”) PD CEN/TR 12896-9:2019, Public Transport Reference Data Model – Informative documentation ==External links== Transmodel NeTEx OpRa
