Wondering what people think of this new system.
bbcA "countdown" timer for pedestrians, which will tell them how long they have to cross the road, has been unveiled in south London.
The first such digital timer to be tested has been placed on Blackfriars Road opposite Southwark Tube station.
The countdown begins after the green man appears and until it turns red.
During the 18-month trial, costing £750,000, eight busy junctions in London will get the timers, including Oxford Circus and the West End.
Charity Living Streets said the scheme was an "expensive way to increase traffic at the expense of pedestrians".
Confusion over symbols
The trial comes after a Transport for London (TfL) study found that about half of the pedestrians crossed junctions even after the red man had appeared.
