What is Transmodel?
Transmodel is the European Reference Data Model for Public Transport Information, standardised as EN 12896 by CEN and published in several parts. It describes the concepts of public transport, such as stops, lines, routes, journeys, vehicles and operators, and how they relate to each other.

A model, not a file format
Transmodel is a conceptual model. It does not define a file format on its own. Instead, formats derive from it. NeTEx is the XML exchange format for planned data, and SIRI is the XML format for real-time data. Because both build on Transmodel, a stop or a journey means the same thing in both.
Why a common model helps
- Shared vocabulary. Operators, authorities and software suppliers can discuss data without misunderstanding.
- Easier mapping. Data from different systems can be mapped to the same concepts.
- Consistency between planned and real-time data. Real-time updates can refer to the same trips and stops as the timetable.
Typical concepts
- Stop place and stop point: a station or stop area, and the point where passengers board.
- Line and route: a service as the public knows it, and the path it takes.
- Journey pattern and service journey: the sequence of stops, and one specific run at a given time.
- Operator and authority: who runs and who orders the service.
Where it appears in MMTIS
Transmodel is not mentioned in everyday use, but it is what makes the European formats consistent. See data formats and the dictionary.
Frequently asked questions
What is the standard number of Transmodel?
EN 12896, published by CEN in several parts.
Do I need to know Transmodel to use NeTEx?
Not in depth, but knowing the main concepts makes NeTEx easier to understand.
