Cities With The World's WORST Commutes (PHOTOS)

Traffic isn't just killing our collective spirit, it's probably holding back the economy, according to a new report.

Ranking the cities with the absolute worst commutes in the world is certainly not an enviable task. The first version of IBM's Global Commuter Pain Survey suggests that some of the most economically important cities in the world are still being greatly affected by their levels of traffic. Transportation infrastructure, it seems, is flat-out failing to keep pace with economic activity. From their release:

IBM surveyed 8,192 motorists in 20 cities on six continents, the majority of whom say that traffic has gotten worse in the past three years. The congestion in many of today's developing cities is a relatively recent phenomenon, having paralleled the rapid economic growth of those cities during the past decade or two. By contrast, the traffic in places like New York, Los Angeles or London developed gradually over many decades, giving officials more time and resources to address the problem.

Disturbingly, nearly half the drivers in the 20 cities IBM surveyed said traffic had gotten worse in the last three years -- and 18 percent said it had gotten significantly worse. Which cities topped the list with the most unendurable commutes in the world?
