Engineers baffled by London Road traffic lights failure
ENGINEERS have been left scratching their heads by a computer glitch causing the failure of the Wycombe Marsh Retail Park traffic lights.
The London Road signals have been malfunctioning for ten days now and workman are still baffled as to how to correct the problem.
Transport for Buckinghamshire said the lights are controlled by two computers – the main one which runs the day-to-day operations and a second safety system that cuts in should the first computer fail.
The safety system has been overriding the main programme, predominantly during the early hours, and shutting off the lights.
TfB’s Rosemary Bryant said engineers with 100 years of experience between them have performed root and branch repairs to the signals.
But it has so far proved unsuccessful and the experts are running out of ideas.
She said: “The lights have been there seven years and we’ve never had a major problem like this with them and now it’s every day.
“The workmen, who must have 100 years of experience between them, have been out there every night for ten nights and they still don’t know why it’s cutting out.
“They have replaced everything - wiring, the lot – but every time they go away thinking they’ve cracked it, the safety system cuts back in again.
“They are rebooting the computer system from scratch today. If that doesn’t work, I’m not sure what the next step will be.”
TfB said London Road and its junctions with the retail park, Micklefield Road and Cock Lane were being closely monitored on traffic cameras – but added the problem was not causing congestion.
