Think you’ve got a bad commute? IBM feels your pain. The tech giant surveyed over 8,000 commuters in 20 cities around the world to find the city with the unenviable title of having the worst commute on Earth…

According to IBM, the cities with the most “commuter pain”–hours spent in traffic, high price of gas, high stress, etc.–include Shenzen, Beijing, and Nairobi. The least painful commutes take place in Chicago, London, and Montreal. Overall, there has been a decrease in traffic since IBM first conducted its survey four years ago, largely because of high fuel prices and weak economies.
