i-Bus? • £117m state-of-the-art Automatic Vehicle Location (AVL) and radio system • One of the world's largest integrated AVL projects • Replacing 5000+ battery operated microwave beacons on lampposts throughout Greater London. • Now on over 75% of London’s 8200 buses. On course to be complete by June 2009 (Hounslow by 31 March 2009)
iBus… how it works • Combination of technologies, including satellite tracking and General Packet Radio System (GPRS) data transfer. • The location of the bus is sent by GPRS about every 30 seconds to a central computer system. • Enhanced location system – a powerful computer using advanced techniques to correct possible problems with satellite-based GPS • Information sent to service controllers, Countdown, traffic lights
Good news for passengers • Visual and audio information on board buses (route, destination, next stop, places of interest) • More reliable information to existing Countdown displays and scope for improved provision of realtime information in the future • Service announcements • More reliable buses (easier service control plus bus priority capability)
Good news for operators and drivers • Easier to manage service • Improved analysis of journey times • Easier to respond to incidents • Automatic low bridge and other location-based warnings • Improved radio coverage • Allows drivers to concentrate on driving rather than making announcements
Countdown II’s on its way… • Existing Countdown technology dates back to the early 90s • TfL is at tendering stage for a new a new Countdown system - Countdown II. • Will include options for various delivery methods including on-street displays, the internet and mobile phones. • Hope to award a contract in May 2009. More information will be available then.
