Human mobility perturbation.

<p><b>A</b>, Statistical distribution of displacements for each 24-hour period. Each line represents the change of numbers of trips within different ranges of displacements. <b>B</b>, Displacement distribution for each 24-hour period. Each line represents a probability density function <i>P</i>(<i>Δr</i>). All plotted distributions followed a truncated power-law distribution (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0112608#pone.0112608.s003" target="_blank">Table S3</a>).
