That’s according to the latest TomTom Traffic Index, compiled by navigation company TomTom, which measures the amount of extra travel time experienced by drivers in cities across an entire year.
Overall congestion levels and morning and evening peak congestion levels were calculated for each city on the index – which this year consists of 390 cities in 48 countries – with each city being given a mark out of 100 as a result.
An overall congestion level of 36%, for example, means that an average trip made takes 36% longer than it would under uncongested conditions.
Anyone that’s visited Mexico City probably won’t be surprised to learn that it’s come out on top of the list (66%), followed by Bangkok (61%), Jakarta (58%), Chongqing (52%) and Bucharest (50%) in the top five.
Istanbul is the only other European city in the top ten (and part of it is in Asia), with Rio de Janeiro and Beijing ranked in eighth and tenth respectively.
Although it doesn’t feature in the index, meanwhile, data from the TomTom website reveals that London is ranked at 40% (data from 2016) and that the worst day for traffic last year was June 23rd, a Thursday.
