Overview
ISO/TR 17185-2:2015 - Intelligent transport systems - Public transport user information - Part 2 - is a Technical Report that catalogs and cross-references public transport data and interface standards. The report compares standards developed in different regions and uses the CEN Transmodel classes as a common reference to map and explain equivalent data concepts. Its main purpose is to help stakeholders understand the concepts, overlaps and differences among existing specifications for public transport passenger information to promote interoperability and faster deployments.
Key Topics
- Standards comparison and catalogue: Side-by-side mapping of regional and national standards to a Transmodel reference, showing like concepts and terminology differences.
- Data concept definitions: Clear treatment of core data concepts such as class, attribute, data element, data frame, message and object, with equivalences across standards.
- Mapping of artefacts: Mapping of Transmodel artefacts to other standards (e.g., classes, attributes, business areas) and descriptions of conformance.
- Methodology and survey: Business plan, typology of public transport standards, and a documented methodology used to collect and map data.
- Annexed comparisons: Informative annexes with detailed class-attribute comparisons for standards such as GTFS, NeTEx, SIRI, TCIP, Korean ATIS, and Japanese ATIS.
- Assessment and gaps: Analysis of overlaps, missing requirements and opportunities to extend narrower specifications using enterprise-based models.
Applications
- System integration and data translation: Use the catalogue to translate terminology and data between standards (for example, mapping a “trip” in GTFS/TCIP to a “service journey” in Transmodel).
- Interoperability planning: Support transit agencies, operators and vendors in selecting compatible standards and mixing standards from different regions.
- Rapid deployment: Reduce duplication of work by reusing existing standards and interfaces when building passenger information, journey planning, or real-time systems.
- Standards adoption strategy: Help policymakers and procurement teams evaluate which standards or combinations best meet national or regional needs.
- Developer reference: A lookup resource for software developers, system integrators and consultants implementing public transport user information services.
Who Should Use It
- Public transport authorities and operators
- ITS architects, system integrators and software developers
- Standards bodies and technical committees
- Vendors of passenger information and journey-planning systems
- Policy makers and procurement teams focused on cross-border interoperability
Related Standards
- CEN Transmodel (reference data model)
- NeTEx, SIRI (CEN XML-based protocols)
- GTFS (General Transit Feed Specification)
- TCIP (Transit Cooperative Interface Profiles)
- Regional ATIS standards (Korean ATIS, Japanese ATIS)
- IFOPT, APTA references and other ITS documentation
ISO/TR 17185-2:2015 is an essential catalogue for anyone implementing or integrating public transport user information systems who needs to understand and bridge multiple data and interface standards for seamless passenger experiences.
