scope:

Update of CEN/TS 15531 respecting the results of the projects in different countries using the specification and taking into account new demands. The existing standard was developed by CEN TC278 WG3 SG7 starting in 2002 and published in 2007. It facilitates interoperability between information processing systems of the transport operators (Automatic Vehicle monitoring Systems: AVMS) in order to allow a better vehicle management as well as the delivery of real time information to end-users. The main elements of the standard are: - A communication layer, which defines common procedures for requesting and exchanging of data. The communication procedures are the same for all services and with that represent the interface infrastructure (message referencing, error handling, reset behaviour). Reusing it for the various technical services ensures cost-effective implementation and extension of the interface. o Request/Response o Publish/Subscribe Subscriptions define the type and volume of data to be exchanged. - An interface between control centres (AVMS) with the functions o connection protection (time or journey related) o connection information (time related) o real time passenger information (Departure Board, stop centric) o general message service (event and information message service) o time table information and network topology (Planned Data Exchange) o vehicle activity (VIS) - An interface for time table information between control centres (AVMS) and information systems with the functions o real time schedule information o Reference data service for schedule information. The new work item will consider the work of - Other sub-groups pf WG3: * SG4 Data Base Model for Public Transport (TRANSMODEL) * SG9 Network and Timetable Exchange (NeTEx) - National Mirror Groups Justification Since SIRI has been developed demands for information by interested public bodies and especially customers of public transport have risen substantially. ...
