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

Javni prevoz - Vmesnik za storitev informiranja v realnem času za potrebe delovanja javnega prevoza - 5. del: Vmesniki funkcijske storitve izmenjave podatkov: Izmenjava podatkov o situaciji
Področje tega WI je posodobitev standarda CEN/TS 15531-5:2011, ki opisuje strukturiran model incidentov za prekinitve storitev v obliki, ki je neposredno povezana s subjekti drugih storitev SIRI. Incidente je mogoče nato povezati neposredno s postajami, linijami, potovanji itd., in sicer na dva načina: kot vzrok za prekinitev ali kot rezultat težav s storitvijo. Storitev za nadzor incidentov omogoča filtriranje po atributih modelov za incident, storitev in lokacijo. Prve uvedbe storitve izmenjave podatkov o situaciji so pokazale številne izboljšave in manjše izboljšanje, potrebno za uspešno in enotno uporabo specifikacije v prihodnosti. Glavni elementi te delovne postavke bodo: o priprava posodobljene izdaje TS v obliki dokumenta, o posodobitev splošne sheme XSD delov SIRI 1–5. V novi delovni postavki bo upoštevano delo o podjetij za javni prevoz ali ponudnikov IT v Nemčiji, o podjetij za javni prevoz ali ponudnikov IT v Franciji, o podjetij za javni prevoz ali ponudnikov IT na Švedskem, pri čemer bo v njihovih projektih uporabljena storitev izmenjave podatkov o situaciji.

Introduction
Public transport services rely increasingly on information systems to ensure reliable, efficient operation
and widely accessible, accurate passenger information.
Well-defined, open interfaces have a crucial role in improving the economic and technical viability of
Public Transport Information Systems of all kinds. Using standardised interfaces, systems can be
implemented as discrete pluggable modules that can be chosen from a wide variety of suppliers in a
competitive market, connecting diverse systems; rather than as monolithic proprietary systems from a
single supplier. Interfaces also allow the systematic automated testing of each functional module, vital
for managing the complexity of increasing large and dynamic systems. Furthermore, with a well-
defined, version interface, individual functional modules can be replaced or evolved, without
unexpected breakages of obscurely dependent function.
The SIRI framework is a European Technical Specification that provides a specification for a number of
functional interfaces that allow public transport data of specific types to be exchanged readily using
structured interfaces.
This further Technical Specification 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.
This document 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. It is an additional functional service based on the
European Technical Specification known as “SIRI” − Service Interface for Real-time Information. SIRI
provides a framework for specifying communications and data exchange protocols for organisations
wishing to exchange Real-time Information (RTI) relating to public transport operations.
The specification for the base SIRI framework on which SIRI-SX is built is presented in three parts:
a) context and framework, including background, scope and role, normative references, terms and
definitions, symbols and abbreviations, business context and use cases (SIRI Part 1: EN 15531-1);
b) the mechanisms to be adopted for data exchange communications links (SIRI Part 2: EN 15531-2);
c) data structures for a series of individual application interface modules (SIRI Part 3: EN 15531-3):
1) Production Timetable (SIRI-PT);
2) Estimated Timetable (SIRI-ET);
3) Stop Timetable (SIRI-ST);
4) Stop Monitoring (SIRI-SM);
5) Vehicle Monitoring (SIRI-VM);
6) Connection Timetable (SIRI-CT);
7) Connection Monitoring (SIRI-CM);
8) General Message (SIRI-GM).
