Research conducted by sat nav firm TomTom found the Capital was the worst city outside London.
It also found Edinburgh had seen the sixth biggest increase in traffic congestion in the UK over a six-month period.
Labour’s transport spokeswoman Lesley Hinds said: “This is very worrying and if we just ignore it, it will get worse.”
Council transport convenor Gordon Mackenzie said: “Same old nonsense from TomTom.”
