It was revealed last week that four new bus-lane cameras would be installed and there would be new road restrictions to ensure buses get priority on the route from the city centre to the new South Glasgow Hospitals.
The plan involved two new cameras on the 'Squinty' bridge and another two in Govan. Also included are some lanes which will be bus-only, with taxis, private hire cars and cycles banned from them.
Glasgow Taxis, which operates the city's black cabs said the move would cost customers and suggested it was a money-making venture.
Taxi drivers who stray into the lanes could face fines and potentially other action from the taxi enforcement unit.
Stephen Flynn, vice chairman of Glasgow Taxis Ltd, said: "If nothing else this will have an impact on the paying customer - be that a local resident or a visiting tourist - who may face being forced to wait in traffic and pay more.
"It could also see licensed taxis held up through no fault of their own and delayed in attending pick-ups."
