On behalf of the UK, RTIG has contributed to the definition of a CEN standard to define a “Service Interface for Real-time Information” (SIRI). It is intended to be used to exchange information between servers containing real-time public transport vehicle or journey time data.

These include the control centres of transport operators and information systems that utilise real-time vehicle information, for example, to deliver services such as travel information.

This report outlines the background to SIRI and describes the different functional services provided as well as addressing how SIRI can be used in procurements.
