Fundamental differences between home/work and other locations. (a) The duration spent at either home or work is relatively flat distributed with peaks around characteristic time spans of 14 h at home as well as 3.5 and 8.6 h at work. By contrast, the time spent at other activities is broadly distributed. For a guide to the eye, Gaussian distributions are fitted around the characteristic durations for home/work locations and a power law with an exponential cut-off is fitted for other locations. Our model captures these main characteristics. (b) The frequency of observing an inter-event time τ between the beginning of two similar activities, if another location has been visited in between. For the home and work location, daily routines dominate the distribution with additional characteristic times. By contrast, the distribution for other locations exhibits a broad distribution dominated by short inter-event times with a suppressed daily routine. For a guide to the eye, the characteristic inter-event time between home location is approximated by a Gaussian distribution and in the inset a power law with exponent −1 is included.
