Public transport - Service interface for real-time information relating to public transport operations - Part 4: Functional service interfaces: Facility monitoring

Scope

This document specifies an additional SIRI functional service to exchange information about changes to availability of facilities, between monitoring systems and 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. As for Transmodel, public transport modes include new modes of transport (vehicle sharing, vehicle pooling, etc.). This document describes the SIRI Facility Monitoring service, one of a modular set of services for the exchange of Real-time information. The Facility Monitoring service (SIRI-FM) is concerned with the exchange of information about alterations to the availability of facilities for passengers among systems, including equipment monitoring, real-time management and dissemination systems.
• To provide real-time progress information about individual vehicles;
• To manage the movement of buses roaming between areas covered by different servers;
• To manage the synchronisation of guaranteed connections between fetcher and feeder services;
• To exchange planned and real-time timetable updates;
• To distribute status messages about the operation of the services;
• To provide performance information to operational history and other management systems.
Implementations SIRI 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 projects of
o PT companies and IT-suppliers especially in Switzerland, Germany, France, Netherlands and Sweden
o Railway traffic
o accessibility in public transport
