1. A method for predicting crowd formation based on the 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 at least one demographic value from a user profile associated with at least one user using a mobile device within the plurality of mobile devices based on the collected plurality of location data snapshots;

    receiving the requested at least one demographic value associated with the at least one user using the mobile device within the plurality of mobile devices;

    determining a plurality of device positions corresponding with each mobile device within the plurality of mobile devices based on the collected plurality of location data snapshots;

    determining a device movement direction corresponding with each mobile device within the plurality of mobile devices based on the determined plurality of device positions;

    determining a device velocity corresponding with each mobile device within the plurality of mobile devices based on the determined plurality of device positions;

    identifying a mobile device subset within the plurality of mobile devices, wherein the mobile device subset converges on a convergence area based on the determined device velocity corresponding with each mobile device within the plurality of mobile devices;

    determining if the mobile device subset within the plurality of mobile devices converging on the convergence area exceeds a convergence threshold value;

    determining if the received at least one demographic value associated with the at least one user using the mobile device within the identified mobile device subset exceeds a demographic threshold value; and

    triggering a convergence response based on determining the mobile device subset converging on the convergence area exceeds the convergence threshold value and determining that the received at least one demographic value associated with the at least one user using the mobile device within the identified mobile device subset exceeds a demographic threshold value.
