Here's a survey I've found online for commuting times in the US (job category/minutes):

An article from a different resource reveals:
Marylanders spent an average 30.8 minutes getting to work, the survey found.
Only New Yorkers took more time in 2005, with a mean commute of 31.2 minutes.
If a survey based on job category is ever conducted in Dubai, it'd show a horrendous disparity. The poor construction laborer spends hours everyday traveling from his camp in Muhaisna to a construction site in the Marina (for instance). While a general manager may only need 10 minutes to get to his workplace.
My own commuting time hovers around 35 mintues. That is 25-30 minutes in the morning, and 40-45 minutes in the way back.
What about you guys?
