On a busy morning commute, it may feel as if the entire world is trying to get to work at the same time. But a fascinating interactive map from FlowingData shows that commute times can vary widely depending on where in the country you live.

A lot of commuters leave for work between 7 and 8 a.m., including about half of those in many Midwest counties. That particular hour is the darkest on the map.  

FlowingData noticed some unusual commute times that are late at night or early in the morning; for example, in Nevada's Humboldt County, more than one-fourth of commuters head out the door when it's still dark outside.

Mineral, Nev., and Loving, Texas, are two counties where many commuters have to leave between 6 and 6:29 a.m.

Most parts of the country have a low rate of commuters in the late afternoon and evening, but the Aleutians East Borough in Alaska is an exception thanks to commercial fishing. The 2,500 commuters in the area tend to operate on a schedule opposite that of the rest of the United States.

Of course, how early people leave in the morning often depends on how far they need to go.

Some 600,000 Americans have "megacommutes" of at least 90 miles and 50 minutes each way, while 10.8 million commuters spend more than an hour getting to work and then the same amount of time getting home, Reuters reported last May. That compares with the national average commute time, which was 25.5 minutes as of 2011.

Unsurprisingly, big cities tend to have long commute times. San Francisco has an average travel time of 32.2 minutes, while Atlanta comes in at 34.3 minutes on average, according to Forbes.

New York boasts the dubious honor of highest average commute time (36 minutes) even though it has the second highest percentage of mega commuters.
