New software is being trialled to try to reduce deaths on London's roads, Transport for London (TfL) has confirmed.
Two systems will be tested out by bus drivers, including the 'Cycle Safety Shield' which is designed to detect pedestrians, cyclists and motorcyclists nearby.
Three seconds before a potential collision, the system gives a red visual warning, followed by an audible alert to the driver.
TfL says it wants to reduce the number of people killed or seriously injured by 40 per cent over the next seven years.
The BBC's Tom Edwards went to see the technology in action.
