Determining qualified devices using zone information

A system comprising:

• at least one processor;
• and
• at least one computer readable storage medium, excluding transitory signals, coupled to the at least one processor, and storing executable computer program instructions, wherein the computer program instructions, when executed by the at least one processor, cause the processor to perform steps comprising:
• receiving traffic data associated with physical presence of a set of devices at a physical location,
• wherein the received traffic data includes log data associated with the physical presence of the set of devices received from a sensor at a zone associated with the physical location;
• based at least in part on the traffic data, determining a duration of time that a given device included in the set of devices has been physically present at the physical location;
• classifying at least some of the devices included in the set of devices as qualified devices when the determined duration of time that the given device has been physically present at the physical location is between a threshold minimum amount of time and a threshold maximum amount of time;
• creating a set of sessions associated with one or more of the qualified devices, wherein creating sessions includes determining a device-zone-duration 3-tuple for each of the one or more qualified devices satisfies at least two criteria for creating the set of sessions;
• and
• outputting information associated with the created set of sessions, wherein the information includes a set of metrics indicating a count of qualified devices located at the zone for each of multiple periods of time.

A method comprising:

• receiving traffic data associated with physical presence of a set of devices at a physical location,
• wherein the traffic data includes log data received from sensors at multiple zones associated with the physical location;
• for a device in the set of devices, detecting, based on the traffic data, a duration of time the device has been physically present at the physical location and an identifier of the zone;
• creating sessions associated with multiple devices in the set of devices, wherein creating sessions includes determining whether the duration of time and the identifier of the zone detected for one of the multiple devices satisfy one or more criteria for creating the sessions;
• and
• outputting a set of metrics associated with the created sessions, wherein the metrics include an indication of a count of devices that were physically located at both a first zone associated with the physical location and a second, different zone associated with the physical location.

A computer readable storage medium, excluding transitory signals, and storing executable computer program instructions that when executed by a processor cause the processor to perform steps comprising:

• receiving traffic data indicating physical presence of a set of devices at a physical location from a sensor at a zone associated with the physical location;
• classifying a device in the set of devices as a qualified device if a duration of time the device has been physically present at the physical location is between a threshold minimum amount of time and a threshold maximum amount of time;
• for each of multiple qualified devices, creating a set of sessions associated with the qualified device upon determining that a device-zone-duration tuple for the qualified device satisfies at least two criteria for creating the set of sessions;
• and
• generating metrics for the created set of sessions based on the duration of time a respective qualified device has been physically present at the physical location.
