Bangkok has the worst evening rush hour traffic in the world for a second consecutive year, according to GPS manufacturer TomTom.
根据GPS生产商TomTom的调查结果，曼谷连续第二年成为全球晚高峰堵车最严重的城市。
The results were compiled after TomTom tracked a years-worth of traffic in 390 cities across 48 countries.
Here is the 2017 ranking of cities with the most severe evening rush hour traffic:
Bangkok, Thailand
Mexico City, Mexico
Bucharest, Romania
Jakarta, Indonesia
Moscow, Russia
Chongqing, China
Istanbul, Turkey
St. Petersburg, Russia
Zhuhai, China
Santiago, Chile
Guangzhou, China
Shijiazhuang, China
Shenzhen, China
Los Angeles, US
Beijing, China
TomTom's senior traffic expert Nick Cohn said that Thailand -- and many other big cities at the top of the congestion ranking -- have become victims of their own success. Growing economies and surging populations translate into more traffic and commuters.
"It would be a challenge for any city government [to] keep things moving," he said, noting that as more people have moved to Bangkok's low-density suburbs, commuter traffic has worsened.
While Mexico City has the second worst evening rush hour traffic in the world, TomTom considers the Mexican capital to be the world's worst city for full-day traffic congestion.
"It could be middle of the day or late at night, but it's just really, really congested," said Cohn.
"Mexico City has an extensive subway system but it doesn't extend out to where all the population growth is happening," he said. "People don't have a lot of options for getting to work."
Moscow, which ranks as the fifth worst city for evening rush hour traffic, was higher up the rankings in past years. But congestion has eased a bit since city officials introduced new parking rules.
Cohn said the city now charges for some parking, which "really changed people's behavior."
