Abstract

Based on an idea that there is a correlation between the number of mobile terminals 300 detected inside a facility (that is, a detected terminal count) and visitors of the facility, the number of users using the facility (that is, a crowd condition of the facility) is estimated using a WiFi function provided in the mobile terminals 300 . Consequently, the crowd condition of the facility can simply be estimated while costs are suppressed to be low, compared to conventional methods in which, e.g., infrared modules or Web cameras are provided at entrances/exits of a facility to estimate a crowd condition.

Claims (40)

1. A crowd condition estimation system for estimating a crowd condition of a facility, the system configured to perform the steps of:

detecting a probe request transmitted from a mobile terminal, the probe request relating to wireless communication;

counting a number of pieces of terminal identification information included in the probe requests detected within a set length of time;

storing an estimation algorithm for estimating a number of users of a facility;

estimating a number of users using the facility based on the counted number of pieces of terminal identification information and the estimation algorithm; and

outputting the estimated number of users using the facility,

wherein estimating the number of users using the facility is based on a parameter that is at least a parameter relating to a style of the facility, the counted number of pieces of terminal identification information, and the estimation algorithm.

2. The crowd condition estimation system according to claim 1 , wherein:

the probe request includes radio field strength information indicating a radio field strength; and

the system is further configured to perform the steps of detecting the probe request if the radio field strength of the probe request, the radio field strength being indicated in the radio field strength information, exceeds a radio field strength threshold value.

3. The crowd condition estimation system according to claim 1 , wherein estimating the number of users using the facility is based on a parameter that is at least a parameter relating to an ambient environment of the facility.

4. The crowd condition estimation system according to claim 3 , wherein the system includes:

a terminal apparatus configured to perform the steps of:

detecting the probe request transmitted from the mobile terminal;

counting the number of pieces of terminal identification information included in the probe requests detected within the set length of time, and

an analysis server, connectable with the terminal apparatus via a communication network, configured to perform the steps of:

storing the estimation algorithm for estimating the number of users of the facility;

estimating the number of users using the facility based on the counted number of pieces of terminal identification information and the estimation algorithm; and

outputting the estimated number of users using the facility, and

displaying a change graph indicating a change in estimated number of users using the facility on a display apparatus.

5. A crowd condition estimation method for estimating a crowd condition of a facility, the method comprising:

a detection step of detecting a probe request transmitted from a mobile terminal, the probe request relating to wireless communication;

a counting step of counting a number of pieces of terminal identification information included in the probe requests detected within a set length of time;

an estimation step of estimating a number of users using the facility based on the counted number of pieces of terminal identification information and an estimation algorithm for estimating a number of users of a facility; and

an output step of outputting the estimated number of users using the facility,

wherein the estimation step of estimating the number of users using the facility is based on a parameter that is at least a parameter relating to a style of the facility, the counted number of pieces of terminal identification information, and the estimation algorithm.

6. A non-transitory recording medium storing a program for causing a computer including a storage section that stores an estimation algorithm for estimating a number of users of a facility, to perform:

a detection step of detecting a probe request transmitted from a mobile terminal, the probe request relating to wireless communication;

a counting step of counting a number of pieces of terminal identification information included in the probe requests detected within a set length of time; and

an estimation step of estimating a number of users using the facility based on the counted number of pieces of terminal identification information and an estimation algorithm for estimating a number of users of a facility,

wherein the estimation step of estimating the number of users using the facility is based on a parameter that is at least a parameter relating to a style of the facility, the counted number of pieces of terminal identification information, and the estimation algorithm.

7. A crowd condition estimation system for estimating a crowd condition of a facility, the system configured to perform the steps of:

detecting a probe request transmitted from a mobile terminal, the probe request relating to wireless communication;

counting a number of pieces of terminal identification information included in the probe requests detected within a set length of time;

storing a plurality of estimation algorithms for estimating a number of users of a facility;

selecting any one of the estimation algorithms;

estimating a number of users using the facility based on the counted number of pieces of terminal identification information and the selected one of the estimation algorithms; and

outputting the estimated number of users using the facility,

wherein selecting any one of the estimation algorithms to be used for estimation, according to a type or a value of a parameter that is at least a parameter relating to a style of the facility and a parameter relating to an ambient environment of the facility,

estimating the number of users using the facility is based on the parameter that is at least the parameter relating to a style of the facility, the counted number of pieces of terminal identification information and the selected one of the estimation algorithms.
