France (11/2019)

- Ile-de-France Mobilité: The biggest French SIRI project is from Ile-de-France Mobilité (Authotity for Paris area) where a SIRI Hub gathers the realtime information of about 80 operators. The aggregated resulting information is available for all operators but also to end users via the open data access (SIRI Lite). The IDFM project, of course, triggers 80 other SIRI projects (one for each provider).
- Marseilles (RTM) also has a SIRI project developed by Diginext (https://www.diginext.fr/fr/cat-actus-fr/505-information-voyageur-rtm)
- Ile-et-Vilaine department is using Hopen Go solution (Navocap) using SIRI (https://www.navocap.com/nos-solutions/hopen-go/): Hopen Go is available in more than 20 locations.

United Kingdom (4/2010)

Kizoom uses it to connect about 16 real-time systems to the national traveline system which has timetable for the whole country and real time for some areas.
For one example see http://leicestertravel.info/

The SIRI framework is now also being used in the UK UTMC XML framework for road traffic e.g. see

Atleast 50 sites in the uk using SIRI since some of the main AVL suppliers, e.g. ACIS are using it for all their installations.

The national “NextBuses” service makes extensive use of SIRI_SX. The architecture of this service, very simply, involves a national platform to which users make their enquiries. That national platform determines where it can get real-time information from for the requested stop - and also from which traveline region it can get scheduled times for that same stop. It sends two enquiries out - one to the real-time system, and one to the regional traveline system. The responses from those two enquiries are blended to give (as far as possible) the real-time information where it exists - and the scheduled times for services which do not have real-time information - in the response sent to the enquirer. This means that we have nationwide coverage through a single information service, whether or not an area is covered with real-time information - including for stops where only some services are known by the real-time system.

GVB uses CEN SIRI and CEN NeTEx as the basis for its passenger information broker system, called the GVB Single Point of Truth (GVB-SPOT). It communicates data to the stop information system using SIRI-ET, GM and SM.
A real time travel information service is in dveleopment, that will feed data to all vehicles and ships, using SIRI ET, SM, CM and GM. FM will probably follow shortly.
