A study of traffic congestion in 18 British metropolitan areas found that it worsened in half of them last year.
The INRIX Traffic Scorecard study, which uses GPS vehicle movement data, looked at congestion Europe-wide for the final three-quarters of 2013 and found that it had increased for the first time in two years, thanks to a rise in economic activity.
London road users saw the biggest deterioration, with drivers wasting an average of 82 hours last year, a 10-hour increase on 2012. Greater Manchester was second, with a two-hour rise to 46 hours, followed by Merseyside at 39 hours, also up two hours.
Fourth-placed South Nottinghamshire, also 39 hours, was four hours worse than before. Fifth-placed Greater Birmingham saw an extra 60-minute delay, taking it to 33 hours.
