Public transport - Service interface for real-time information relating to public transport operations - Part 5: Functional service interfaces: Situation exchange


Service Interface for Real Time Information (SIRI) is a specification for an interface that allows systems running computer applications to exchange information about the planned, current or projected performance of the public transport operations. The scope of this WI is to update CEN/TS 15531-5:2011 which describes structured incident model for disruptions to services, in terms that relate directly to the entities of other SIRI services. Incidents can then be directly linked to stops, lines, journeys, etc in two ways: as the cause of disruption or as the result of service problems. The Incident Monitoring Service is capable of filtering on incident, service and location model attributes. First implementations of the Situation Exchange Service have revealed a number of improvements and some minor enhancements necessary for a successful and uniform usage of the specification in the future. The main elements out of this work item will be: o Prepare an updated edition of the TS as a document o Update the common XSD of SIRI parts 1-5 The new work item will consider the work of o PT companies and IT-suppliers in Germany o PT companies and IT-suppliers in France o PT companies and IT-suppliers in Sweden using Situation Exchange Service in their projects.
