摘要

A number-of-terminals estimation device (10) includes: a location data acquisition unit (11) to acquire location data which are a collection of multiple pieces of location information including location registration information; a first presence count estimation unit (15) to estimate a first presence count to be the number of terminals in observation area during observation period, based on the location data; a signal removal unit (16) to extract location data in accordance with a type of location data from the location data; a second presence count estimation unit (17) to estimate a second presence count to be the number of terminals in observation area during observation period, based on extracted location data; and a third presence count estimation unit (18) to estimate a third presence count to be the number of terminals in observation area during observation period, based on one or both of first and second presence counts.
