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.
PD CEN/TS 15531-5 on SIRI Situation Exchange service is useful for:
The SIRI Situation Exchange service (SIRI-SX) allows the efficient exchange of data about Situations caused by planned and unplanned incidents and events. Situations are actual or potential perturbations to the normal operation of a transport network.
PD CEN/TS 15531-5 on SIRI Situation and Incident Exchange service allows the exchange of incident and event information between, amongst others such as Control centres, Operations Staff, Public Information systems, Alert systems and personalised alert systems, UTMC systems, Journey planners, and AVMS (Automatic Vehicle Management Systems).
PD CEN/TS 15531-5 guidelines help to exchange information messages between identified participants in a standardised structured format suitable for travel information services. It enables messages to be sent and to be revoked.
