AMSTERDAM, The Netherlands – TomTom released the results of its 2017 Traffic Index today which details the most traffic congested cities around the world.

Mexico City, Mexico was once again named the most traffic congested city in the world. According to the data, drivers in the Mexican capital expect to spend an average of 66% of extra travel time stuck in traffic at anytime of day. 

The TomTom Traffic Index uses data from the previous calendar year and looks at the traffic congestion situation in 390 cities in 48 countries on six continents. It works with nearly 19 trillion data points that have been accumulated over nine years. This is the sixth year of the TomTom Traffic Index.

North America’s top five most congested cities remained the same as 2016.

This year, Canada had two cities that placed in the top 10 most congested list for North America. Vancouver (39%) was ranked fourth in North America, while Toronto (30%) took eighth place. Montreal (29%) was kicked out of the top 10 by Portland, Ore., but ranked 11th.

This is where our expertise in traffic comes in, and it’s why we release the TomTom Traffic Index every year. It’s designed to help drivers, cities and transport planners to understand traffic congestion and, most importantly, how to reduce it.”
