摘要

A number-of-terminals estimation device includes: a location data acquisition unit to acquire location data which are a collection of multiple pieces of location information including location registration information; a first presence count estimation unit 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 to extract location data in accordance with a type of location data from the location data; a second presence count estimation unit 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 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.
