Victoria Line Event Real Time Disruption


Some of the Challenges



• Currently the Victoria line has 2 million customer journeys per year and increasing.

• The population of London is projected to increase equivalent to the population of Birmingham over the next 10 to 15 years.

• VL Stations have multiple interchanges to other LU lines, National Rail, International Rail, London Overground and multiple Bus routes.

• Suspensions and delays on other LU lines and transit services are reflected as interchange disruption on the Victoria line.

• VL is fast moving, any disruption develops quickly and requires immediate customer information from the control centre.

Overground Overground

Extensive Interchanges



• Other line part suspension can be distant and not directly affects a VL interchange.

• Other line suspension can severely impact an interchange.

The Challenges

Variable Other Line Disruption



• The Piccadilly line has multiple interchanges with 3 interchanges.

• The Northern line has multiple and complex interchanges with 4 interchanges and 2 routes.

• So interchanging VL customers are impacted dependant on extent, location and route of

Northern and Piccadilly lines disruption.

The system had to be designed and implemented to address the challenges.

• To provide a manageable maintainable Real Time Disruption system based on a flexible and expandable model.

• To simply and rapidly instigate and manage information to customers on both stations and trains that reflect developing disruption in real time.

• To enable exchange of Real Time Disruption data across the LU and between other rail and transit networks based on common data.

• To provide customers with trusted disruption information prioritised for their current location to help them make informed decisions about changing their journey. [Traffic Shaping]

Event Driven Real Time Disruption



The User currently selects from a library of 80,000+ predefined Events with associated messages arranged in up to 255 volumes.

There are currently volumes for every LU line, National and International Rail, Overground, Buses and Airports.

Each volume covers disruption relating to Service Suspensions, Part Suspensions, Delays and Station Closures, Station Facilities and Interchanges

For each disruption Event, the disruption cause [Alerts, Incidents, Emergency Services, Engineering, Passenger, Staff, Weather… etc].

For each disruption Event, some additional information [Listen for further announcements, Replacement Bus Services… etc].

The User Selects and Activates an Event.

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

When the Event is activated associated disruption messages are added to the Current Active Message List which is broadcast to Stations and Trains.

RTD Messages to Trains

Current Active Message List is broadcast to operational trains every 30 Seconds [up to 40 messages]

Each RTD Message is only 38 bytes in size [one quarter of a phone text message]

The Current Active Message List is broadcast to both train cabs via train radio The inactive rear cab radio acts as a data modem and routes the broadcast to the train Passenger Information System

Event Driven Real Time Disruption On the Trains


As well as the customer facing text [above], the RTD Message is also categorised and contains location and priority control flags which react with the Victoria line RTD Profile to dynamically determine.

The locations at which a message is processed to display

The priority of the message at each location


Victoria Line RTD Profile

The RTD Profile is installed onto each train as part of a CIS upgrade.

Each Victoria Line location has an individual RTD Profile card. The profile is a simple array of 16 bit binary values. [White =1 Grey =0] Where the binary values of the RTD message react with the binary values of the profile, the RTD Message will be processed to display at that priority.

Dependant on Profile and RTD Message values,, the RTD message can have 4 routes from low to high priority.

Modification of train journey based information is conducted dynamically by each train dependant on control flags within the RTD Message

• The system is based on an end user fully configurable RTD database based on evolving customer needs.

• Functionality for an interactive Traffic Shaping common CIS Network.

• Functionality to drive future TFT screen displays with Text, Images, Video and Icons.

• Structuralised RTD messages to facilitate the application of message component shedding with the message remaining understandable.

• Reduced RTD messaging by announcing common disruption across multiple lines.

• The functionality to attach multiple RTD Messages to a single RTD Event to address high priority RTD messages at multiple locations.

• The ability to background upgrade the full Train fleet upgrade and provide automatic changeover facilitated by the use of current and upgrade RTD databases.

• The functionality to monitor user behaviour with the Impact Assessment Process during times of high task load.

• The functionality to schedule RTD Events to reduce user repeditive task loads.

• The system is provided embedded backup system so that in times of data network failure the Control Centre user can operate normally and provide RTD information via voice radio to train operators.
