Digital Signs - a major infrastructure project for London
With more than 6 million people using London Buses every day, there’s a huge requirement from the travelling public to provide localised customer insight into the services proved by Transport for London. Meeting this requirement Aardvark have supported Transport for London in improving the visibility of bus arrival and departure times along with any known delays. Launching initially in selected third parties such as hospitals, doctors surgeries, colleges and other public services, the digital Signs project enables customised maps to be produced for display at each location. Each sign is tailored to show data appropriate to the location, showing the requested local bus stops on a map, with real-time bus data streamed onto it and alongside, identifying route destinations and expected bus arrival times along with any known delays.

Aardvark developed an eCRM toolset for Transport for London staff to create and deploy the digital signs for client locations across the capital.

The eCRM platform also provides lifecycle emails, tracking of possible fraudulent sign-use and API performance monitoring. The project was technically challenging as the platform needs to be able to capture live arrival data on 16,000 Bus stops, processing hundreds of updates every second via the Transport for London Countdown API.

The solution Aardvark deployed is highly resilient – split across multiple servers, any one of which can fail without a perceptible loss in performance and, in a disaster recovery situation, the platform can fail over to another location entirely, and restore in under half an hour without any human intervention.
