The new paradox: Mobile but sedentary

The distance people travel for professional purposes is increasing. Scientists are taking a closer look at these 21st century nomads, uncovering the reasons behind the long kilometers and the consequences on commuters' lives. It's the crack of dawn and they're already behind the wheel, in the train or at the airport. Some spend several nights a week in a furnished studio in another city or a suburban hotel. These heavy business travelers ("grands mobiles" in French) are the21st century's western nomads. They are often quite attached to their homes, but have been uprooted professionally, sometimes by choice, sometimes not. Based on a European study conducted in 2007 and 2011, EPFL researchers have sketched the profiles of these travelers: people who spend more than two hours a day commuting and bi-residents who spend more than 60 nights a year away from their primary residence.
