Population estimating apparatus, program and population estimating method

A population estimating apparatus comprising:

• a population information acquiring unit to acquire local population information indicating a population of a local area having a predetermined geographic range;
• a second terminal extracting unit to refer to a log information storing unit to store log information in which one or more pieces of positional information indicating each position of one or more wireless terminals are associate with time information indicating time at which each of the one or more pieces of positional information is acquired, and extract wireless terminals existing in a local area at particular time;
• a relation parameter deriving unit to derive a relation parameter, which is used for estimating population, representing a relation between a number of wireless terminals and a population, based on the population of the local area indicated by the local population information and a number of wireless terminals extracted by the second terminal extracting unit;
• and
• a relation parameter storing unit to store, with respect to at least a part of the wireless terminals extracted by the second terminal extracting unit, terminal identification information to identify the wireless terminals and a relation parameter derived by the relation parameter deriving unit such that they are associated with each other.

A population estimating method comprising:

• an inputting step to input input information indicating a geographic range and time of population estimation;
• a first terminal extracting step to refer to a log information storing unit to store log information in which one or more pieces of positional information indicating each position of one or more wireless terminals are associated with time information indicating time at which each of the one or more pieces of positional information is acquired, and extract wireless terminals existing in a geographic range indicated by the input information at time indicated by the input information;
• and
• a relation parameter extracting step to refer to a relation parameter storing unit to store a relation parameter predetermined for each wireless terminal, which represents relation between a number of wireless terminals and population, and extract a relation parameter applied to a wireless terminal extracted in the first terminal extracting step;
• and
• an estimation value deriving step to derive an estimation value of a population in the geographic range indicated by the input information at the time indicated by the input information, based on the relation parameter extracted in the relation parameter extracting step.
