World's worst commuter cities: Beijing, Mexico City at top

Hate your commute? Well, workers from Mexico City to Beijing have no pity for you. According to an IBM commuter pain study of 8,192 motorists in 20 cities, 67% complained that traffic has gotten worse in the past three years. The respondents also stated that their long and tiring commute has a negative effect on their job leaving them feeling sick, angry, and unproductive.

Researchers found that increased traffic congestion causes greater economic problems for cities. Workers who are stuck in traffic will most likely go back home or move out. Not only does this effect the area of residence which experiences a population decline, but the surrounding areas must expand to accommodate for the influx of newcomers. City planners are then stuck in a gridlock, pardon the pun.
