(Main)Service Interface for Real Time Information (SIRI) - Part 7: Passenger Real-Time Information European Profile
Service Interface for Real Time Information (SIRI) - Part 7: Passenger Real-Time Information European Profile
The main objective of this WI is to define a SIRI Passenger Real-Time Information European profile:
• To identify a minimum subset of SIRI with codification rules and constraints for a European level plug and play exchange of real-time passenger information data between organisations at a European level
• To reflect already existing NeTEx profiles defined at national level (Norway, France, Sweden, etc.).
• To maintain a relevant real-time information dataset, as small and simple as possible, to ensure interoperability is maximised while at the same time enabling exchange of supplementary national real-time data that will not interfere with the core international dataset
• To complement the EPIP (NeTEx European Passenger Information Profile) with real-time passenger information
• To establish quality assessment procedures for implementing validation and quality assessment tools - including compliance checking rules - necessary to fulfil the requirement of the Commission
This profile will complement the NeTEx Passenger information profile and NeTEx Accessibility profile (under drafting) in order to get a set of consistent European profiles fulfilling the requirements of the Priority Action "A" of the ITS Directive.

Javni prevoz - Vmesnik za informiranje v realnem času za potrebe delovanja javnega prevoza - 7. del: Evropski profil za informacije o potnikih v realnem času
Ta dokument je profil skupine standardov EN oziroma CEN/TS 15531. Osredotoča se na ustreznost informacij v storitvah zagotavljanja informacij o potnikih, ki izpolnjujejo pričakovanja delegirane uredbe Direktive o inteligentnih prometnih sistemih (storitve zagotavljanja večmodalnih potovalnih informacij po vsej EU, delegirana uredba Komisije (EU) 2017/1926 MMTIS DR, spremenjena z Uredbo (EU) 2024/490).
Vmesnik SIRI je namenjen izmenjavi podatkov v realnem času in dopolnjuje format NeTEx za izmenjavo rednih podatkov. Oba temeljita na modelu Transmodel (skupina standardov EN 12986). Vmesnik SIRI podpira izmenjavo informacij, pomembnih za storitve javnega prevoza za informacije o potnikih in sisteme AVMS.
Kot pri večini standardov za izmenjavo podatkov je opredelitev podnizov podatkov in namenskih pravil za določene primere uporabe v veliko pomoč izvajalcem ter zagotavlja splošno interoperabilnost. Ta podniz se običajno imenuje »profil« in profil v tem dokumentu se uporablja samo za informacije o potnikih.
Ta profil je zasnovan tudi tako, da dopolnjuje profil EPIP (NeTEx) z informacijami v realnem času, zato se imenuje EPIP-RT: oba profila sta dobro oblikovana in ju je mogoče uporabljati nemoteno (na nacionalni ravni v nacionalnih točkah dostopa (NAP) ali na kateri koli lokalni ravni, kjer se dosledno zagotavljajo tako redne informacije kot tudi informacije v realnem času).

Overview
SIST-TS CEN/TS 15531-7:2025 is a technical specification from the Slovenian Institute for Standardization (SIST), aligned with CEN (European Committee for Standardization). Titled Service Interface for Real Time Information (SIRI) - Part 7: Passenger Real-Time Information European Profile, this standard defines a European profile for the exchange of real-time passenger information in public transport networks. The main goal is to streamline and harmonize real-time data exchange across European countries to achieve plug-and-play interoperability, supporting both cross-border and national passenger information services.
This European profile is intended to become the minimum working subset of SIRI-using agreed rules for codification and constraints-and complements NeTEx (Network Timetable Exchange) profiles established at national levels. Ultimately, the standard enables seamless integration and high-quality passenger information across different organizations and IT systems, and supports requirements set out by the European Commission for Intelligent Transport Systems (ITS).
Key Topics
Minimum SIRI Subset and Codification Rules
- Defines the essential components and allowable data structures for cross-border interoperability
- Applies uniform coding and data constraints to support seamless plug-and-play integration
Interoperability and Simplicity
- Keeps the core dataset simple and small, essential for wide adoption
- Allows addition of supplementary national data without interfering with the standardized core
Alignment with NeTEx Profiles
- Leverages lessons and approaches from national NeTEx profiles (France, Norway, Sweden, etc.)
- Ensures compatibility with the existing European Passenger Information Profile (EPIP) for NeTEx
Quality Assessment and Validation
- Specifies procedures and compliance checks to ensure reliable data exchange
- Provides tools for validation and ongoing assessment of data quality
ITS Directive Compliance
- Contributes to fulfilling Priority Action "A" within the European ITS Directive, improving real-time travel information for passengers
Applications
The SIST-TS CEN/TS 15531-7:2025 standard is highly relevant for:
Public Transport Operators and Authorities
- Facilitates real-time exchange of timetable, vehicle location, and disruption information
- Enables better, more accurate passenger information at stops, in journey planners, and via apps
IT Solution Providers and Developers
- Provides a clear, interoperable framework for developing European-ready real-time information systems
- Simplifies integration across borders and between multiple operators
National and Regional Transport Networks
- Allows networks to maintain unique operational data while participating in the wider European real-time passenger information ecosystem
Passengers and End Users
- Benefits from more consistent, up-to-date, and reliable real-time information, leading to improved travel experiences
Compliance and Procurement
- Public administrations and transit agencies can specify this standard to ensure solution compatibility and future-proof system upgrades
Related Standards
For comprehensive and effective deployment, this standard should be considered in relation to:
- CEN/TS 15531-1 to 15531-6 - Other parts of the SIRI standard, covering different aspects of real-time information exchange
- NeTEx (EN 16614 series) - Network Timetable Exchange standards, particularly the EPIP (European Passenger Information Profile)
- ITS Directive 2010/40/EU - Establishes the legal framework for ITS deployment, including the provision of real-time transport information
- SIST-TS CEN/TS 16614 series - Covers accessibility and other passenger information data profiles in conjunction with this real-time profile
In summary: The SIST-TS CEN/TS 15531-7:2025 European Passenger Real-Time Information Profile is essential for enabling interoperable, accurate, and up-to-date traveler information across Europe’s public transport networks, supporting smarter mobility and high-quality passenger service delivery.
