According to the techniques presented herein, location data from signals transmitted by a plurality of mobile wireless devices in a wireless network are obtained. For each mobile wireless device, location data time points are aggregated to generate a plurality of routines or paths of movement for each mobile wireless device within a predefined space. The predefined space is partitioned into a plurality of units and each routine of the plurality of routines is also partitioned into a plurality of subroutines or segments. For each unit, one or more subroutines within a predefined distance of a frequent subroutine are combined with the frequent subroutine, and the frequent subroutines may be displayed on a graphical interface to visualize aggregate movement of the plurality of mobile wireless devices within the predefined space. Frequent subroutines may be analyzed in an automated manner to generate notifications and alerts.
