Thailand's capital is known for being among some of the more congested cities in Southeast Asia, but a new study has now placed its traffic jams second just behind Mexico City.

According to Dutch navigation firm TomTom, Bangkok's traffic moves 57% slower on average compared with a clear road situation. During morning peak hours, it slows to a further 85%, and a snail-like 114% in the evening.

Mexico City, in first place, has traffic chugging at 59% slower on average, but never reaches the kind of pace that Bangkok does during its peaks. Mexico City peaks at 97% in the morning, and 94% in the evenings.

The only other Asian city on the list is Chengdu, in China, with 41% slower traffic on average.

Cities in Brazil, however, make multiple appearances on the list, starting with Rio de Janeiro in fourth, followed by Salvador and Recife in seventh and eighth place.

TomTom owns Tele Atlas, one of the world's largest mapping and navigation companies that competes with American firm Navteq.
