1. A method for predicting crowd formation based on movement of a plurality of mobile devices, the method comprising:

  • collecting a plurality of location data snapshots based on the plurality of mobile devices and a plurality of cell towers;

    requesting a plurality of demographic values from a plurality of user profiles associated with a plurality of users using the plurality of mobile devices based on the collected plurality of location data snapshots;

    receiving the requested plurality of demographic values associated with each of the plurality of users, the plurality of users each using a mobile device collectively forming the plurality of mobile devices;

    determining a plurality of device positions corresponding with each of the mobile devices of the plurality of mobile devices;

    determining a device movement vector for each mobile device within the plurality of mobile devices based on changes from comparing the determined plurality of device positions with each mobile device over a time period;

    calculating a directional convergence by (i) determining a slope of the line for each determined device movement vector and then (ii) determining a point where a plurality of the determined slope of the lines intersect;

    determining a future device position corresponding with each of the mobile devices within the plurality of mobile devices based on the calculated directional convergence;

    determining when a mobile device subset within the plurality of mobile devices exceeds a convergence threshold value based on the determined future device position corresponding with each of the mobile devices;

    determining when the received plurality of demographic values corresponds to a subset of users associated with the mobile device subset exceeds a demographic threshold value; and

    triggering a convergence response based on the mobile device subset exceeding the convergence threshold value, and determining that the received plurality of demographic values corresponding to the subset of users associated with the mobile device subset exceeds the demographic threshold value.
