London was identified as Europe’s slowest city, by some distance, while a further six British cities were ranked in the top 10 slowest cities in Europe.
London has an average traffic speed of 11.8mph, making the capital 3.2mph slower than Berlin in second place and 4.3mph slower than Warsaw in third, with Manchester and Edinburgh completing the top five. Glasgow, Bristol and Belfast are also in the top 10.
In London, it is quicker to hop on a bike, as cyclists at rush hour recorded an average speed of 14mph.
The results come at time when public transport in London is increasingly under the spotlight.
Malcolm Murray-Clarke, director of congestion charging at TfL, stated that traffic in the capital has been reduced by 20% since the congestion charge was introduced but London is still far and away the slowest city in the study.
