The document discusses the event driven real time disruption (RTD) system used on the Victoria Line in London. It describes the challenges of providing timely customer information given the line's high speeds and extensive interchange connections. The system allows control centre operators to select predefined disruption events which then generate associated messages. These messages are transmitted to stations and trains to be dynamically prioritized and displayed based on location. The system provides customers with trusted, journey-specific disruption information to help them make informed travel decisions.

16. Event Driven Real Time Disruption
When Event activation is instigated an automatic embedded decision support
process is automatically initiated.
The selected Event is automatically assessed against current active Events for
contradictory or redundant information.
If impact is detected, decision support intervenes and the User is presented
with a list of impacted and proposed Events. The User can only select one of
the disruption Events to continue to remain active.
The active Event becomes part of the Current Active Event List
