Public transport - Service interface for real-time information relating to public transport operations - Part 1: Context and framework
1.1 Interfaces specified by this document
1.1.1 Business Context
Real-time information may be exchanged between a number of different organisations, or between different systems belonging to the same organisation. Key interfaces include the following:
- Between public transport vehicle control centres - generally, for fleet and network management.
- Between a control centre and an information provision system - generally, to provide operational information for presentation to the public.
- Between information provision systems - generally, sharing information to ensure that publicly available information is complete and comprehensive.
- Between information provision systems - and data aggregation systems that collect and integrate data from many different sources and different types of data supplier and then distribute it onwards.
- Between information provision systems and passenger information devices such as mobile phones, web browsers, etc.
Annex B describes the business context for SIRI in more detail.
SIRI is intended for wide scale, distributed deployment by a wide variety of installations. In such circumstances it is often not practical to upgrade all the systems at the same time. SIRI therefore includes a formal versioning system that allows for the concurrent operation of different levels at the same time and a disciplined upgrade process.
In this general framework, SIRI defines a specific set of concrete functional services. The services separate the communication protocols from the message content (‘functional services’). This allows the same functional content to be exchanged using different transport mechanisms, and different patterns of exchange. Figure 1 below shows this diagrammatically.
1.1.2 SIRI Communications
SIRI provides a coherent set of functional services for exchanging data for different aspects of PT operation. A common data model, based on Transmodel 6.0, is used across all services.

Öffentlicher Verkehr - Dienstschnittstelle für Echtzeitinformationen bezogen auf Operationen im öffentlichen Verkehr - Teil 1: Kontext und Grundstruktur
Transport public - Interface de service pour les informations en temps réel relatives aux opérations de transport public - Partie 1 : Cadre et contexte
1.1.1 Contexte économique
Les informations en temps réel peuvent être échangées entre différentes organisations ou entre différents systèmes appartenant à la même organisation. Les interfaces clés incluent ce qui suit :
• Entre les centres de contrôle des véhicules de transport public – généralement pour la gestion de parcs et de réseaux.
• Entre un centre de contrôle et un système de diffusion d'informations – généralement pour fournir des informations opérationnelles destinées à être mises à la disposition du public.
• Entre les systèmes de diffusion d'informations – généralement pour partager des informations afin de garantir que les informations accessibles au public sont complètes et détaillées.
• Entre les systèmes de diffusion d'informations et les systèmes d'agrégation de données qui collectent et intègrent les données provenant de différentes sources et de différents types de fournisseurs de données, puis les distribuent ensuite.
• Entre les systèmes de diffusion d'informations et les appareils d'information voyageur tels que les téléphones mobiles, les navigateurs Web, etc.
L'Annexe B décrit le contexte économique de la norme SIRI d'une manière plus approfondie.
La norme SIRI est destinée au déploiement réparti à grande échelle pour de nombreuses installations. Dans de telles circonstances, la mise à niveau de tous les systèmes en même temps est souvent irréalisable. C'est pourquoi la SIRI inclut un système formel de contrôle des versions qui permet le fonctionnement simultané de différents niveaux en même temps ainsi qu'un processus de mise à niveau discipliné.
Dans ce cadre général, la norme SIRI définit un ensemble spécifique de services fonctionnels concrets. Les services séparent les protocoles de communication du contenu du message (« services fonctionnels »). Cela permet au même contenu fonctionnel d'être échangé par le biais de différents mécanismes de transport et schémas d'échange. La Figure 1 ci-dessous en est une illustration schématique.

Javni prevoz - Vmesnik za informiranje v realnem času za potrebe delovanja javnega prevoza - 1. del: Skladnost in okvir
Vmesnik za informiranje v realnem času (SIRI) je specifikacija za vmesnik, ki sistemom, v katerih se izvajajo računalniške aplikacije, omogoča izmenjavo informacij o načrtovanem, trenutnem ali predvidenem poteku javnega prevoza.
Področje uporabe tega dokumenta WI je posodobitev standarda CEN/EN 15531-1:2015, ki parom strežniških računalnikov omogoča izmenjavo strukturiranih informacij v realnem času o voznih redih, vozilih in povezavah, skupaj s splošnimi informativnimi sporočili, povezanimi z delovanjem storitev. Podatke je mogoče uporabiti za različne namene, na primer za:
• zagotavljanje informacij o dejanskem času odhoda s postajališča, ki so prikazane na postajališčih, v internetu in mobilnih sistemih za dostavo;
• zagotavljanje informacij o poti posameznih vozil v realnem času;
• upravljanje poti avtobusov med območji, ki jih pokrivajo različni strežniki;
• upravljanje sinhronizacije zajamčenih povezav med storitvami pridobivanja in podajanja;
• izmenjavo načrtovanih in sprotnih posodobitev voznega reda;
• distribucijo statusnih sporočil o delovanju storitev;
• zagotavljanje informacij o učinkovitosti za operativno zgodovino in druge sisteme upravljanja.
Izvedbe vmesnika SIRI razkrivajo številne izboljšave in nekatere podrobnosti, potrebne za uspešno in enotno uporabo specifikacije v prihodnosti.
Glavni elementi teh popravkov bodo:
• priprava posodobljene izdaje tehnične specifikacije kot dokumenta;
• posodobitev skupnega XSD-ja delov vmesnika SIRI 1–5.
Nova delovna postavka bo obravnavala projekte:
• PT-podjetij in IT-dobaviteljev, zlasti v Švici, Nemčiji, Franciji, na Nizozemskem in Švedskem;
• železniškega prometa;
• dostopnosti v javnem prometu.

European foreword
This document (EN 15531-1:2022) has been prepared by Technical Committee CEN/TC 278 “Intelligent
transport systems”, the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by February 2023, and conflicting national standards shall be withdrawn
at the latest by February 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 15531-1:2015.
SIRI (CEN/TS 15531-1:2006) has been a CEN Technical Specification since 2007 and a European normative
standard since 2013 and has been widely used in Europe and elsewhere and proven its usefulness. This
document proposes a revised version of SIRI as a European Standard, and is currently submitted to the
Formal Vote. The proposed revisions are minor enhancements arising from experience of the deployment of
SIRI in many live systems. This document also clarifies the relationship of SIRI to NeTEx, the CEN Technical
Standard for the XML exchange of Public Transport Reference data based on the Transmodel CEN European
Standard.
This document presents Part 1 of the European Standard known as “SIRI”. SIRI provides a framework for
specifying communications and data exchange protocols for organisations wishing to exchange Real-time
Information (RTI) relating to public transport operations.
The SIRI European Standard is presented in three parts:
• context and framework, including background, scope and role, normative references, terms and
definitions, symbols and abbreviations, business context and use cases (Part 1),
• the mechanisms to be adopted for data exchange communications links (Part 2),
• data structures for a series of individual application interface modules PT, ET, ST, SM, VM, CT, CM, GM
(Part 3).
Two additional parts define additional functional services as CEN Technical Specifications:
• additional data structures for additional application interface module FM (Part 4),
• additional data structures for additional application interface module SX (Part 5).
The XML schema can be downloaded from https://github.com/SIRI-CEN/SIRI, guidance on its use, example
XML files, and case studies of national and local deployments is located at http://siri-cen.eu/.
It is recognised that SIRI is not complete as it stands, and from time to time will need to continue to be
enhanced to add additional capabilities. It is therefore intended that a SIRI Management Group should
continue to exist, at European level, based on the composition of SG7.
Any feedback and questions on this document should be directed to the users’ national standards body. A
complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cro
