What is PD CEN/TS 15531-5 - SIRI Situation Exchange service about?
Public transport services rely on information systems to ensure reliable, efficient operation and widely accessible, accurate passenger information. The Standard Interface for Real-time information (SIRI) provides a specification for a number of functional interfaces that allow public transport data of specific types to be exchanged readily using structured interfaces.
PD CEN/TS 15531-5 specifies an additional SIRI functional service to exchange incident and event information about disruptions to public transport between servers containing real-time public transport vehicle or journey time data. These include the control centres of transport operators as well as information systems that deliver passenger travel information services.
PD CEN/TS 15531-5 describes the SIRI Situation Exchange service, one of a modular set of services for the exchange of Real-time information. The Situation Exchange service (SIRI-SX) is concerned with the exchange of planned events and unplanned incident data among systems, including incident capture, real-time management and dissemination systems. The SIRI-SX service uses the common SIRI communication framework and services which are described in EN 15531-1 and EN 15531-2.
