Terminal-count estimation device and terminal-count estimation method

A number-of-terminals estimation device comprising:

• a location data acquisition unit for acquiring location data which are a collection of multiple pieces of location information including location registration information;
• a first presence count estimation unit for estimating the number of terminals located in an observation area during an observation period, as a first presence count, based on the location data acquired by the location data acquisition unit;
• a signal removal unit for removing location registration information generated due to a crossing of a terminal across a location registration area boundary, from the location data acquired by the location data acquisition unit, to obtain location data after removal;
• a second presence count estimation unit for estimating the number of terminals located in the observation area during the observation period, as a second presence count, based on the location data after removal obtained by the signal removal unit;
• and
• a third presence count estimation unit for estimating the number of terminals located in the observation area during the observation period, as a third presence count, based on one or both of the first presence count obtained by the first presence count estimation unit and the second presence count obtained by the second presence count estimation unit.

A number-of-terminals estimation method executed by a number-of-terminals estimation device, comprising:

• a location data acquisition step of acquiring location data which are a collection of multiple pieces of location information including location registration information;
• a first presence count estimation step of estimating the number of terminals located in an observation area during an observation period, as a first presence count, based on the location data acquired in the location data acquisition step;
• an extraction step of extracting location data in accordance with a type of location data, from the location data acquired in the location data acquisition step;
• a second presence count estimation step of estimating the number of terminals located in the observation area during the observation period, as a second presence count, based on the extracted location data;
• and
• a third presence count estimation step of estimating the number of terminals located in the observation area during the observation period, as a third presence count, based on one or both of the first presence count acquired in the first presence count estimation step and the second presence count acquired in the second presence count estimation step.
