TomTom Releases 'Most Traffic Congested City' Data

Posted on March 23, 2016

TomTom recently released the results of the TomTom Traffic Index 2016, the annual report detailing the cities around the world with the most traffic congestion. The big news this year is Istanbul has been knocked off the top spot by Mexico City.

Drivers in the Mexican capital can expect to spend an average of 59% extra travel time stuck in traffic at any time during the day, and up to 103% in the evening peak periods when compared to a free flowing, or uncongested, situation. This adds up to 219 hours of extra travel time per year.

Completing the top five most congested cities in the world are Bangkok (57%), Istanbul (50%), Rio de Janeiro (47%), and Moscow (44%), making up the top five most congested cities in the world.

Using data from 2015, the TomTom Traffic Index analyses the traffic congestion in 295 cities in 38 countries on six continents – from Rome to Rio, Singapore to San Francisco. TomTom works with 14 trillion data points that have been accumulated over eight years. This is the fifth year of the TomTom Traffic Index.  

Congestion Up, Globally

Looking at TomTom’s historical data, it’s clear traffic congestion is up by 13% globally since 2008. But there are shocking differences between continents. While North America’s traffic congestion has increased by 17%, Europe has only increased by 2%. This could be driven by economic growth in North America, and economic depression in the rest of Europe.

Worryingly for businesses there is a direct correlation between a reduction in traffic and economic growth. Commenting in his analysis of the report, Wendell Cox, principal of Demographia, said: “There is considerable economic research indicating that the more fluid the traffic in an urban area, the greater its likely economic growth. For example, an urban area in which residents can reach 80% of the jobs in 30 minutes is likely to perform better economically than if only 70% or 60% of the jobs can be reached in that time.”

Taco van de Leij, VP Marketing at TomTom Telematics, said: “It’s clear that governments and businesses alike need to adopt smarter methods to help reduce traffic. Customers using our WEBFLEET fleet management solution are already taking a first step towards this with access to a wide range of tools to help make better decisions for their fleets. Through more intelligent routing and job scheduling, telematics can optimise traffic flow, meaning vehicles spend less time on the road, and by being able to tap into TomTom’s world class Traffic Services they are able to further reduce travel times.

Business owners can find out more about the TomTom Traffic Index, and discover where their home city ranks at There’s also helpful advice on beating traffic congestion, as well as independent analysis. And, for the first time, a selection of ‘Profile Cities’ provide insight into what they are doing to improve mobility.

    Los angeles traffic problem is due to vehicles that deive in the fast lane slow, trucks on the car pool (chp has not issued tickets, flyaway buses in carpool when there is no traffic, octa out of service buses in car pool lanes. California will loose federal $$$$$$ due to their traffic research showing no improvement to flow after their improvements. California highway patrol could help and reduce the problems in 3 weeks by having motorcycle officer move the turtles on the car pool and fast lane. And issue tickets to box trucks on car pool lane. England has digital signs that tell drivers what speed to drive to help avoid and reduce congestion. Nevada is planning a 200 million dollar project to reduce parking lots on the freeways- too bad they are not doing it on the california/las vegas
