Passengers need multi-modal travel information which is accurate, timely, consistent and clear. Never is this more important than when a journey is disrupted. Arguably, disruption information is the most important information to passengers. When everything is running smoothly and as expected, many regular passengers will use information only to confirm what they already know. When there is an incident and the route or schedule of their current journey is disrupted, then they need to know how their journey is changing and how, under these new circumstances, they can still get to their destination.
During 2012-13 and 2015, RTIG held several events to explore with members how disruption information could best be facilitated. This document addresses one of these: the use of incident management system standards, and in particular SIRI-SX, to enable business to business communication of disruption to public transport services.
