SCOTLAND'S largest local authority should follow the example set be Liverpool and temporarily scrap the city's bus lanes, a motoring expert has said.

Liverpool city council kicked off a nine-month experiment yesterday to assess traffic flow in the city without its bus lanes, after the city's mayor, Joe Anderson, claimed they had not reduced congestion.

Bus lane camera enforcement has been used on 24 bus lanes in Liverpool since 2009, but drivers have complained about being caught out by poor signage and it was claimed that a single camera was responsible for half of all the fines issued.

Now there are calls for Glasgow City Council to follow Liverpool's lead and temporarily suspend its bus lane cameras. Glasgow has had 11 enforced bus lanes since April 2012, and last week rolled out an additional five so-called "supercameras", capable of catching 50 times as many motorists.

Neil Greig, director of policy at the Institute of Advanced Motoring, said: "We need more of this kind of thing. It's a time-limited experiment looking in detail at the whole enforcement of bus lanes.

"It think that's a very good idea and given Glasgow's recent problems it's something they might want to consider too, because while they say they 'review these things regularly' this is a proper, thorough review."

It was revealed yesterday that a single bus lane camera out of 11 in Glasgow has been responsible for a quarter of the penalty charge notices issued to drivers.

A spokesman for Glasgow City Council said it had no plans to replicate the Liverpool trial.

He added: "Regrettably, some drivers continue to break the law, and as with many other driving offences, camera enforcement is an effective deterrent."
