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

The SIRI Situation Exchange service (SIRI-SX) allows the efficient exchange of data about situations caused by planned and unplanned incidents and events and is intended to support the use cases identified in Annex C. Situations are actual or potential perturbations to normal operation of a transport network. The SIRI-SX service uses the common SIRI communication framework and services which are described in CEN/TS 15531-1 and not repeated in this document.
The Situation Exchange service has a rich Situation model, allowing a structured description of all aspects of multimodal travel Situations, including cause, scope, effect and rules for distribution to an audience. The structured values enabling computer based distribution through a wide variety of channels, and the presentation of data in different formats for different device and different audiences. The Situation Exchange Service allows the exchange of incident and event information between, amongst others:
- Control centres;
- Operations staff;
- Public information systems;
- Alert systems and personalised alert systems;
- UTMC systems;
- Journey planners;
- AVMS (Automatic Vehicle Management Systems).
SIR-SX uses a network model based on the CEN Transmodel conceptual model for public transport networks, schedules and operations, along with the CEN Identification of Fixed Objects in Public Transport (IFOPT) model for describing physical transport interchanges.
The Situation Exchange service is envisaged as a 'back office' capture and exchange service that will feed other public facing travel information dissemination systems, in particular those using the TPEG format. Transport Protocol Expert Group (TPEG) is a European Broadcasting Union fostered standard for broadcasting travel data over Digital Assisted Broadcasting (DAB) radio and other channels. To this end, the SIRI-SX situation classification model has been harmonised as far as possible with that of TPEG and DATEX2 so that full interoperability can be achieved. Uses of structured elements from TPEG, for which translations already exist in most European languages, also facilitates human readability in different national languages. Maintaining and improving a harmonisation with TPEG will be a continuing objective. In addition to the TPEG exchangeable content, SIRI-SX messages contain additional structured information which allows them to be processed in additional ways.
Situation and computer systems and applications are typically distributed, that is information will be captured on one system and exchanged with others for dissemination and further processing. This means that a message design is needed that allows the management of the identity of distributed messages over time and across different systems, so that subsequent updates to a Situation can be reconciled by different systems over a network, and obsolete messages can be retired automatically. The SIRI-SX situation model is designed to support the distributed management of Situations.

Javni prevoz - Vmesnik za storitev informiranja v realnem času za potrebe delovanja javnega prevoza - 5. del: Vmesniki funkcijske storitve - Izmenjava podatkov o situaciji

Storitev izmenjave podatkov o situaciji SIRI (SIRI-SX) omogoča učinkovito izmenjavo podatkov o situacijah, ki jih povzročijo načrtovani in nenačrtovani incidenti in dogodki, ter je namenjena podpori primerov uporabe, identificiranih v dodatku C. Situacije so dejanske ali morebitne motnje normalnega delovanja transportnega omrežja. Storitev SIRISX uporablja skupni komunikacijski okvir SIRI in storitve, ki so opisane v CEN/TS 15531-1 in se v tem dokumentu ne ponavljajo. Storitev izmenjave podatkov o situaciji ima bogat model situacij, ki omogoča strukturiran opis vseh vidikov situacij multimodalnega prevoza, vključno z vzrokom, učinkom in pravili za distribucijo občinstvu. Strukturirane vrednosti omogočajo računalniško distribucijo prek različnih kanalov in predstavitev podatkov v različnih formatih za različne naprave in različna občinstva. Storitev izmenjave podatkov o situaciji omogoča izmenjavo informacij o incidentih in dogodkih tudi med: nadzornimi centri; operativnimi delavci; javnimi informacijskimi sistemi; alarmnimi sistemi in personaliziranimi alarmnimi sistemi; sistemi UTMC; načrtovalci poti; AVMS (avtomatskimi sistemi upravljanja vozil). SIRI-SX uporablja omrežni model, ki temelji na konceptualnem modelu Transmodel CEN za omrežja, urnike in obratovanje javnega prevoza, skupaj z modelom Identifikacija stalnih predmetov v javnem prevozu (IFOPT) CEN za opis fizičnih prevoznih izmenjav.
