The Lord Mayor of Dublin Fergus O'Brien tries out the new pedestrian crossing designed to assist the blind and visually impaired on Lord Edward Street in Dublin.

Partially sighted Michael Fahy, a Dublin Corporation employee, accompanied the Lord Mayor as he tried out the new audio signals. 

The high pitched bleep is the signal to cross.

The fitting of an audio signal to the lights at Lord Edward Street is the thirtieth adaptation to a crossing in 1981, coinciding with International Year of the Disabled. The cost of installing each audio signal is about £100. 

Commenting on the new signal service, Michael Fahy says,

All partially sighted and blind people have difficulty crossing the road... It's good that Dublin Corporation thought about us.
