London is the world’s slowest city core for drivers due of widespread 20mph speed limits, according to new study.
Journeys of 10 kilometres (6.2 miles) in central London took an average of 37 minutes and 20 seconds last year, location technology provider TomTom said.
London was ranked first in the slow city centre ranking for the second year in a row. This was one minute longer than in 2022 and the longest duration among the 387 cities across 55 countries examined.
A representative for Sadiq Khan, the mayor of London, called the survey “misleading.”
The world’s second slowest city core was discovered to be Irish capital Dublin, with 10km trips average taking 29 minutes and 30 seconds.
It was followed by Toronto, Canada (29 minutes); Milan, Italy (28 minutes and 50 seconds); and Lima, Peru (28 minutes and 30 seconds).
In the UK, Manchester was ranked second (23 minutes and 30 seconds), followed by Liverpool (22 minutes and 50 seconds), Bristol (22 minutes and 40 seconds) and Edinburgh (21 minutes and 30 seconds).
Travel times increased last year in 21 of the 25 UK cities analysed.
Transport for London (TfL) cut speed limits to 20mph on a further 65km (40.4 miles) of roads in the south of the capital during the final four months of last year.
When the move was announced in September, the transport body – chaired by Mr Khan – said it would raise the total length of roads with a 20mph limit to 140km (87 miles), making them “safer for everyone”.
