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).
General Information
Overview
CEN/TS 15531-7:2025 - Service Interface for Real Time Information (SIRI) Part 7: Passenger Real-Time Information European Profile - defines a harmonized European profile for exchanging real‑time passenger information. The Technical Specification identifies a minimum subset of SIRI with codification rules and constraints to enable plug‑and‑play, cross‑border data exchange while remaining compatible with existing national NeTEx profiles (e.g., Norway, France, Sweden). It complements the NeTEx European Passenger Information Profile (EPIP) by adding real‑time data and establishes validation and quality‑assessment procedures required by the ITS Directive.
Key topics and technical requirements
- Minimum SIRI subset and codification rules: Specifies a constrained, interoperable core of SIRI elements to be used at European level, with rules for IDs, codespaces and fixed identifiers.
- Compatibility with NeTEx & EPIP: Ensures the profile reflects existing national NeTEx profiles and complements NeTEx EPIP and Accessibility profiles for consistent passenger information exchanges.
- Core services and objects: Defines mandatory services (EPIP‑RT) and message objects such as ServiceRequest, ServiceDelivery, Subscription contexts, and Capability declarations.
- SIRI functional modules: Covers Situation Exchange (SIRI‑SX) for disruptions and incident information and Estimated Timetable (SIRI‑ET) for live journey timing, recorded/estimated calls, vehicle journeys, formation and occupancy structures.
- Data constraints and pre‑defined reference data: Restricts the dataset to a small, relevant set while allowing supplementary national data that does not interfere with the international core.
- Validation and quality assessment: Establishes compliance checking rules and quality assessment procedures for implementing validation tools required by the European Commission.
- Terminology and data types: Standardizes language, place names, framed vehicle references and other structured data types to maximize semantic interoperability.
Practical applications and users
- Who uses it: Public transport authorities, operators, national transport agencies, journey‑planning and ticketing platform providers, real‑time information API vendors, accessibility service providers, and system integrators.
- Use cases: Cross‑border passenger information services, multi‑operator journey planners, live disruption and accessibility notifications, integration of national real‑time feeds into pan‑European services.
- Benefits: Faster integration, reduced custom mapping, improved interoperability, consistent quality and compliance with EU ITS Directive requirements.

Le document SIST-TS CEN/TS 15531-7:2025, intitulé "Service Interface for Real Time Information (SIRI) - Part 7: Passenger Real-Time Information European Profile", propose une standardisation essentielle pour l'échange d'informations en temps réel concernant les passagers au niveau européen. Cette norme s'inscrit dans un contexte où l'interopérabilité des systèmes d'information est primordiale, offrant un cadre de référence pour le développement de solutions efficaces et harmonisées dans le domaine des transports. La portée de cette norme vise à identifier un sous-ensemble minimal de SIRI, accompagné de règles de codification et de contraintes, facilitant ainsi l'échange de données d'information en temps réel entre les organisations au sein de l'Europe. Cela représente un atout majeur pour la création d'une infrastructure de transport intégrée, où les informations peuvent être partagées de manière rapide et fiable entre les différents pays européens. Un des principaux points forts de cette norme est sa capacité à refléter les profils NeTEx existants, déjà définis au niveau national, tels que ceux de la Norvège, de la France et de la Suède. Cela garantit une continuité et une compatibilité avec les systèmes nationaux tout en promouvant une vision européenne cohérente. Un autre avantage notable est l'accent mis sur la simplification du jeu de données d'informations en temps réel. En maintenant un dataset aussi petit et simple que possible, la norme facilite une interopérabilité maximale tout en permettant l'échange de données supplémentaires spécifiques à chaque pays, sans perturber le dataset international de base. La norme complète également le profil EPIP (NeTEx European Passenger Information Profile) en intégrant des informations en temps réel pour les passagers, ce qui est crucial pour répondre aux attentes croissantes des utilisateurs finaux en matière de mobilité. De plus, l'établissement de procédures d'évaluation de la qualité par le biais d'outils de validation et de vérification de conformité renforce la crédibilité et la robustesse de ce cadre normatif. En résumé, le SIST-TS CEN/TS 15531-7:2025 constitue un document fondamental pour l'évolution des systèmes d'information en temps réel dans le transport européen. Sa structure claire et ses objectifs précis pour l'information des passagers en temps réel font de cette norme un outil indispensable pour l'amélioration continue des services de transport à travers l'Europe.
SIST-TS CEN/TS 15531-7:2025は、リアルタイム情報サービスインターフェース（SIRI）の一部として、ヨーロッパにおける乗客リアルタイム情報のプロファイルを定義しています。この標準は、特にヨーロッパレベルでのリアルタイム乗客情報データのプラグアンドプレイ交換を促進することを目的としており、そのための最小限のSIRIサブセットとコーディフィケーションルール、制約が含まれています。 この標準の強みは、既存のNeTExプロファイルを反映させる点にあり、ノルウェー、フランス、スウェーデンなどで定義された国レベルのプロファイルとの整合性が保たれています。これにより、ヨーロッパ全体での相互運用性が最大限に高められ、国ごとの補足的なリアルタイムデータとの交換が可能になります。データセットはできるだけ小規模でシンプルなものとして維持されながら、国際的なコアデータセットと干渉しないよう配慮されています。 さらに、SIST-TS CEN/TS 15531-7:2025は、EPIP（NeTEx European Passenger Information Profile）の補完として、リアルタイム乗客情報を提供し、ITS指令の優先アクション「A」の要求に応じた一貫したヨーロッパプロファイルのセットを確立することを目指しています。また、品質評価手順の確立により、実装における確認ルールや品質評価ツールの検証が行われ、委員会の要件を満たすことが求められます。 この標準は、リアルタイム情報を利用した公共交通の改善に向けた重要な枠組みを提供しており、ヨーロッパ内の様々な組織との情報交換を円滑にするための基盤となるでしょう。非常に実用的で、相互運用性を重視したアプローチは、将来的な交通システムの発展に寄与することが期待されます。

SIRI 표준은 실시간 정보 시스템의 효율성과 신뢰성을 높이는 핵심 요소로 자리잡고 있으며, 실용적이고 용이한 데이터 교환을 통해 유럽 전역에서의 교통 관리 향상에 크게 기여할 것입니다.
The SIST-TS CEN/TS 15531-7:2025 standard, titled "Service Interface for Real Time Information (SIRI) - Part 7: Passenger Real-Time Information European Profile," presents a comprehensive framework that is essential for the development and deployment of passenger real-time information systems across Europe. The scope of this standard is significant as it focuses on establishing a minimum subset of SIRI with specific codification rules and constraints that facilitate a plug-and-play exchange of real-time passenger information data among various organizations at a European level. One of the key strengths of this standard is its alignment with the existing NeTEx profiles defined at the national level, such as those in Norway, France, and Sweden. This alignment ensures that the standard is not only relevant on a continental scale but also leverages already established practices, allowing for a smoother integration into pre-existing systems. Additionally, the standard emphasizes the necessity of maintaining a streamlined real-time information dataset that prioritizes simplicity and interoperability. By doing so, it enables the effective exchange of supplementary national real-time data without disrupting the core international dataset, which is crucial for a cohesive transportation framework. Moreover, SIST-TS CEN/TS 15531-7:2025 plays a vital role in complementing the NeTEx European Passenger Information Profile (EPIP) by incorporating aspects of real-time passenger information. This integration is important for ensuring that the data exchanged is up-to-date and reflects the actual conditions affecting passengers, thereby enhancing the overall travel experience. Furthermore, the standard outlines the establishment of quality assessment procedures, which are critical for implementing validation and quality assessment tools, including compliance checking rules. These procedures are necessary to meet the requirements set forth by the Commission and ensure that the real-time information systems are both reliable and accurate. In essence, the SIST-TS CEN/TS 15531-7:2025 standard is highly relevant to the ongoing development of European transportation networks. It fosters interoperability while ensuring that quality and accessibility are prioritized. Its comprehensive approach to defining a European profile for passenger real-time information positions it as a crucial document for stakeholders involved in the design and implementation of modern public transport solutions across Europe.
Das Dokument SIST-TS CEN/TS 15531-7:2025 definiert einen europäischen Profilstandard für die Dienstschnittstelle für Echtzeitinformationen (SIRI), insbesondere im Hinblick auf die Bereitstellung von Echtzeit-Passagierinformationen. Der Umfang dieses Standards ist vielfältig und von großer Bedeutung für die Harmonisierung der Informationssysteme auf europäischer Ebene. Die Hauptstärke dieses Standards liegt in seiner Fähigkeit, ein Mindestmaß an SIRI zu identifizieren, das durch Codierungsregeln und Einschränkungen für einen „Plug-and-Play“-Austausch von Echtzeit-Passagierinformationen zwischen verschiedenen Organisationen in Europa definiert ist. Diese Standardisierung ermöglicht eine effiziente und effektive Implementierung von Echtzeitdaten, was für die Verbesserung der Benutzererfahrung im gesamten europäischen Verkehrsnetz entscheidend ist. Ein weiterer wichtiger Aspekt des Standards ist die Berücksichtigung bereits bestehender NeTEx-Profile, die auf nationaler Ebene in Ländern wie Norwegen, Frankreich und Schweden definiert sind. Durch diese Integration wird sichergestellt, dass bereits vorgenommene Investitionen und Entwicklungen in nationale Systeme nicht verloren gehen, sondern vielmehr in einem übergeordneten europäischen Kontext weiterverwendet werden können. Ein zentrales Ziel des Standards ist die Bereitstellung eines relevanten Datensatzes für Echtzeitinformationen, der so klein und einfach wie möglich gehalten wird, um die Interoperabilität zu maximieren. Diese Strategie ist entscheidend, um den Austausch nationaler Echtzeitdaten zu ermöglichen, ohne dass dies die integrale internationale Datensammlung stört. Zusätzlich wird der Standard die bestehende NeTEx-Beschreibung zum Passagierinformationsprofil sowie das in Bearbeitung befindliche NeTEx-Zugänglichkeitsprofil ergänzen. Dies führt zu einem konsistenten Set von europäischen Profilen, das die Anforderungen der vorrangigen Maßnahme "A" der ITS-Richtlinie erfüllt und somit die Grundlage für die Entwicklung intelligenter Verkehrssysteme in Europa bildet. Abschließend umfasst der Standard auch Verfahren zur Qualitätssicherung, die notwendige Validierungs- und Evaluierungswerkzeuge sowie Compliance-Überprüfungsregeln einschließen. Diese Maßnahmen sind zwingend erforderlich, um die Anforderungen der Kommission zu erfüllen und die Integrität sowie die Zuverlässigkeit der bereitgestellten Echtzeit-Passagierinformationen zu gewährleisten. Insgesamt bietet SIST-TS CEN/TS 15531-7:2025 einen robusten Rahmen für die Entwicklung und den Austausch von Echtzeitinformationen auf europäischer Ebene, der nicht nur die Interoperabilität fördert, sondern auch eine hohe Datenqualität sicherstellt.
