SIRI
SIRI overview
SIRI was established as European standard in October 2006. It is a CEN (Comité Européen de Normalisation) and Technical Standard that specifies a European interface standard for exchanging information about the planned, current or projected performance of real-time public transport operations between different computer systems.
SIRI allows pairs of server computers to exchange structured real-time information about schedules, vehicles, and connections, together with general informational messages related to the operation of the services. The information can be used for many different purposes, for example:
- To provide real time-departure from stop information for display on stops, internet and mobile delivery systems;
- To provide real-time progress information about individual vehicles;
- To manage the movement of buses roaming between areas covered by different servers;
- To manage the synchronisation of guaranteed connections between fetcher and feeder services;
- To exchange planned and real-time timetable updates;
- To distribute status messages about the operation of the services;
- To provide performance information to operational history and other management systems.
To find out more about the SIRI data model, please visit the Transmodel page and SIRI page.
SIRI National and EU minimum profiles inventory
National profiles are specified to cover the national needs. To help implementation, DATA4PT is also in process of delivering SIRI EU minimum profile, in collaboration with relevant CEN group. DATA4PT has prepared a table with the currently available SIRI national profiles, including an overview of data categories that are currently covered. For data categories relevant to static data check the NeTEx Profiles Inventory.

SIRI extension for New Modes
In line with NeTEx Part 5, corresponding extensions are made in SIRI for real time data such as current number of available vehicles, current number of spaces available to bring back a vehicle or to park, etc. SIRI also provide updates of positions (typically for free floating vehicles). The SIRI Facility Monitoring (FM) service is extended to provide this counted information. Further details are available in the relevant document.
Mapping with GBFS for real time information
In the framework of the CEN work for the extension, a canonical mapping was made between NeTEx Part 5 /SIRI and GBFS. It is available here.
