Standards Harmonisation

This page summarises Standard harmonisation aspects of Transmodel v6.0.

The harmonisation work has involved comparison and analysis of other standards with Transmodel over a period of time, with the resulting modifications being integrated into a number of different areas of Transmodel, including some enhancements to the core Common Concepts model (for example, adding an abstract ROLE MODEL, and an abstract SECURITY LIST MODEL).

The requirements for additional harmonisation have been especially intensive in two particular areas:

  • Harmonisation of the Passenger Information Model (Part 6 of Transmodel v6.0). This is a natural consequence of this module being concerned with the mapping of Transmodel data elements to other APIs and formats.
  • Harmonisation of the Fare & Validation Models (Part 5 of Transmodel v6.0). This is primarily because the Fares part of Transmodel has been extensively revised to meet new requirements from the CEN NeTEx format and other related conceptual standards (see below) – reflecting developments in modern ticketing technology.

The harmonisation work to compare different standards demonstrates the value and power of Transmodel as conceptual tool for the analysis and comparison of different representations of PT data, even if they use different terminology.

  • A comparison of NeTEx and Google’s General Transit Feed Specification (GTFS) provides an especially good example of this. Some notes are included in this report.
  • A further presentation to show the strategic use of Transmodel for harmonising UK standards was developed and delivered to the British Standards Institute.

Figure 1 shows Transmodel as the basis for a family of interoperable data standards.
