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.〔〔http://www.tfl.gov.uk/assets/downloads/TfL-bus-signals-priority.pdf〕 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. ==Announcements== Upon boarding the bus, for example, route 240 serving Edgware, iBus plays the announcement "240 to Edgware" and corresponding text appears on the visual displays. As the bus approaches the stop, the on-board system will announce and display the bus stop name.〔 Since March 2014, the space below this name shows the current time. When a passenger has requested the bus to stop, this is replaced by the message "Bus stopping". Similarly to the London Underground, iBus has a feature that tells passengers to alight at a key stop, which is near a key place that the bus will not serve. For example, a bus arriving at Stratford will say, "Stratford: alight here for Stratford station," and this will scroll across the dot matrix indicators. Each bus contains a Microsoft Windows-based computer〔 that has the details of all 19,000 bus stops in London.〔 The system has over 30,000 announcements for 700 bus routes. The bus driver is able to play recorded announcements such as: * Bus will wait here whilst drivers are changed. * This bus terminates here. Please take all your belongings with you. * This bus is on diversion. Please listen for further announcements. * The destination of this bus has changed. Please listen for further announcements. * The next bus stop is closed. * Watch out for traffic when leaving the bus. * Seats are available on the upper deck. * Please move down inside the bus. * No standing on the upper deck or stairs please. * Smoking is not permitted on London’s buses. * Drinking alcohol is not permitted on London’s buses. * The wheelchair space is now required. Can passengers in this area please make room. Thank you. * Closed circuit television is in operation on this bus. * Please keep all your personal belongings with you at all times. * For everyone’s security, please inform the driver of anything suspicious.〔(【引用サイトリンク】 title=Big Red Book - More than just a driver )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「IBus (London)」の詳細全文を読む スポンサード リンク
