CEN TS 15531 Service Interface for Real time Information (SIRI)
SIRI was established as European standard in October 2006.
In April 2013 the CEN group has finished the final draft of an updated version 2.0 of parts 1-3.
It respects demands which have been dicovered during the use of SIRI in the past years.The documents have been publishe by CEN in 2015.
The Standard-Document can be purchased at the national Standardisation bodies such as Beuth Verlag (Search for: TS 15531)
”Service interface for real-time information relating to public transport operations” SIRI, is a XML protocol for exchange of public transport real-time information. The CEN standard is based on Transmodel.
Service interface for real-time information relating to public transport operations, SIRI consist of three parts:
CEN TS 15531-1:2015
- Part 1: Context and framework
CEN TS 15531-2:2015
- Part 2: Communications infrastructure
CEN TS 15531-3:2015
- Part 3: Functional service interfaces
Two additional parts have been published in 2010
Part 4: CEN/TS 15531-4
Public transport - Service interface for real-time information relating to public transport operations - Part 4: Functional service interfaces: Facility Monitoring (CEN/TS 15531-4:2011)
Part 5: CEN/TS 15531-5
Public transport - Service interface for real-time information relating to public transport operations - Part 5: Functional service interfaces - Situation Exchange (CEN/TS 15531-05:2016)
XSD-Schema (o) for SIRI V2.0 (2015).
Updated versions of SIRI are prepared by CENT TC 278 WG3 SG7. Work on Part 5: Functional service interfaces - Situation Exchange has started in 2018. Work on parts 1 - 3 will start next.
Comments or Change Requests are welcome.

Relationship SIRI - VDV453/454
The VDV Real Time Interfaces 453&454 are widely used in Germany. They have been a major input to the European standard SIRI. Thus they can be interpreted as to be the subset of SIRI to be used in Germany.
Please note that the flat structures in SIRI 1.0, which had been introduced in the first SIRI version for backward compatibility with legacy systems have been deleted in the version 2.0 of SIRI:
You should not use the structures with a name ending on „AsGroup“ but the standard-structures. Example: Use structure “MonitoredVehicleJourney“ instead of “MonitoredVehicleJourneyAsGroup". The latter ones have been deleted in the SIRI Version 2.0.
