This study used a sample of 100,000 mobile phone users whose trajectory was tracked for six months to study human mobility patterns. Displacements across all users suggest behaviour close to the Lévy-flight-like pattern observed previously based on the motion of marked dollar bills, but with a cutoff in the distribution. The origin of the Lévy patterns observed in the aggregate data appears to be population heterogeneity and not Lévy patterns at the level of the individual.
