Wired writes about a report released by IBM Research regarding traffic in large cities. Using a web-based survey, IBM  included 8,192 drivers in 20 cities. IBM developed a “Commuter Pain Index” that is comprised of ten criteria.

The worst cities, starting with the worst and then declining on the index: Beijing, Mexico City, Johannesburg, Moscow, and New Delhi. The first US city, Los Angeles, shows up at #14 with New York and Houston at #17 and #18, respectively.

If you were curious, IBM recommends as a solution new technologies to “empower transportation officials to better understand and proactively manage the flow of traffic.”
