British motorists are wasting even more of their time stuck in traffic jams with London one of the worst-hit cities in Europe despite the congestion charge, new research has found.
Traffic information company Inrix, which conducted the study and pinpointed the UK roads causing the most delays, says the rising congestion mirrors the economic recovery.
The research found the average UK driver spent 30 hours held up in traffic jams last year, compared to 29 in 2012.
UK sixth worst European country for congestion
Meanwhile, motorists in the capital wasted 82 hours in 2013 compared to 72 the year before.
Only drivers in Brussels fared worse than their London counterparts.
Although the UK as a whole was only found to be the sixth worst European country for traffic congestion after Belgium, the Netherlands, Germany, France and Luxembourg.
Bryan Mistele, president and chief executive of Inrix, said the busier roads reflect increasing economic activity.
He said: "So goes traffic, so goes the economy. While bad news for drivers, the increases in traffic congestion in Europe are signs of a slowly recovering economy."
Worst stretch between central London and Heathrow
In the UK, the A4 between central London and junction 3 of the M4 near Heathrow was found to be the worst stretch of road for the number of annual hours of delay caused in the peak period.
During the afternoon peak it was found to cause the average driver 91 hours of delay last year.
All of the UK's 10 most congested roads were in London and all at their busiest in the afternoons, the study found.
After the capital the most congested areas in the UK were found to be Greater Manchester, Merseyside, South Nottinghamshire and Greater Birmingham.
