10 cities in the world with worst traffic jams

People living in cities are the worst victims of traffic congestion. And their woes just get worse every year.

A traffic index created by TomTom, a navigation and GPS systems manufacturer, lists the cities which bear the brunt of traffic snarls.

For instance, a TomTom's study reveals that drivers in China spend an average of nine working days a year stuck in traffic.

The index measures travel time throughout the day and during peak periods and compares them with travel time during non-congested periods.

The difference is expressed as a total average percentage Congestion level.

The TomTom Traffic Index compares travel time during non-congested hours with travel times in peak hours experienced by passenger vehicles.

Take a look at 10 cities across the world with the worst traffic woes…
