Pedestrian countdown timer near Stratford station

Ten new coundown timers will be installed before the Olympics

A countdown timer for pedestrians has been installed outside Stratford station in east London ahead of the Olympics.

Transport for London said in addition to another digital timer in Tooting Bec, eight more will be installed before the Games begin next month.

The timers tell people how long they have to cross the road before the green man symbol turns red.

There will be 18 timers before the Games, rising to 200 by 2014, TfL said.

The first countdown mechanism was unveiled in 2010 opposite Southwark Tube station.

Sharon Grant, chairperson of passenger watchdog London Travel Watch, said: "We have followed the trial with interest and believe the roll out will be welcomed by pedestrians as it will provide them with more certainty about the time they have to cross the road."

Leon Daniels, TfL's managing director of surface transport, said: "We look forward to sharing information to encourage further use of this technology with the London Boroughs and other transport authorities across the UK."
