Most of the pollution in our cities is caused by the huge number of vehicles on the streets, and the traffic caused by rush hour, accidents, road construction sites and many other issues. But actually, which cities have the most city traffic in the world? A study now reveals this.
In fact, we can now know and monitor city traffic and figure out which are the world's busiest cities thanks to the TomTom traffic index, a system that looks at 389 cities in 56 countries on six continents and measures their traffic impact based on travel times, fuel costs and Co2 emissions.
The most virtuous countries are the United States and Australia, while it fares very poorly for some cities in Europe, Asia and South America.
