TomTom, an influential navigation and mapping products provider, released its Worldwide Traffic Index in 2014, analyzing traffic congestion in over 200 cities around the world.

As the pace of urbanization increases in China, traffic jams are common in most Chinese cities, especially in metropolises like Beijing and Shanghai. According to the index, Taipei, Chongqing and Tianjin have the worst traffic in China in 2014, ranking 11th, 12th and 14th on the overall list.

A total of 22 Chinese cities are among the top 100 cities with the worst traffic in the world. Beijing, capital of China, ranks 15th globally.

Aiming to provide unbiased information about congestion in urban areas, the Traffic Index compares travel times during free flow hours with those in peak hours. The list is based on actual GPD measurements from TomTom’s historical traffic database. Local roads, arterials and highways are all taken into account.

Here are the top 10 congested cities in China:
