What is "ibus"

Ibus or IBus may refer to:

• Intelligent Input Bus (IBus), an input-method framework for Unix-like computer operating-systems
• iBus (London), an Automatic Vehicle Location system used on London's buses
• International Bitterness Units scale (IBUs), a measure of the bitterness of beer
• iBUS (device), a bus-monitoring and -management device for road transport systems

The iBus is an Automatic Vehicle Location (AVL) system to improve London's buses using technology installed by Siemens AG. The system tracks all of London's 8000 buses to provide passengers with audio visual announcements, improved information on bus arrivals, and to trigger priority at traffic junctions.

On 16 June 2005 it was reported that London's buses 'fail' deaf people. As a result, the iBus system was announced on 16 January 2006 and was tried on route 149 for an eight-week trial. The system was proved to be successful, and on 18 May 2006, radio presenter Emma Hignett was announced to be the 'Voice of London's Buses' after 99% in the survey said she had the right voice. iBus was launched on many routes in 2007 and continued throughout 2008 and 2009. All routes now have the system.

iBUS or Intelligent BUS Utility System is a bus monitoring and management system device that helps solving traffic problem in the worsening traffic congestion of mass transport system in the developing country metro cities.
