Abstract

A system includes a calculation master storage unit to store a calculation master that is required for estimating the number of visitors to steady mobility facilities within a predetermined period of time, and is obtained by further classifying the steady mobility facilities by type, and a calculation master that is required for estimating the number of visitors to variable mobility facilities within a predetermined period of time, and is based on an actual survey value for each type obtained by further classifying the variable mobility facilities by type, and a building visitor number calculation unit to extract a name of a facility from map information, estimate a type of the facility based on the name, and refer to the calculation master corresponding to the type from the calculation master storage unit based on the estimated type, to calculate an estimate value of the number of visitors to the facility.

Claims

1. A population mobility estimation system, comprising:

a calculation basic information storage unit to store first calculation basic information that is required for estimating the number of visitors to steady mobility facilities within a predetermined period of time, the steady mobility facilities serving as facilities where specific people come in and out routinely, and is obtained by further classifying the steady mobility facilities by type, and second calculation basic information that is required for estimating the number of visitors to variable mobility facilities within a predetermined period of time, the variable mobility facilities serving as facilities where unspecified people come in and out in a fluid manner, and is based on an actual survey value for each type obtained by further classifying the variable mobility facilities by type; and

an arithmetic means for extracting detailed information including at least a name of one of the facilities from map information, estimating a type of the facility based on the extracted name of the facility, and referring to the first calculation basic information or the second calculation basic information that corresponds to the type from the calculation basic information storage unit based on the estimated type, to calculate an estimate value of the number of visitors to the facility within a predetermined period of time.

2. The population mobility estimation system according to claim 1, further comprising a variation pattern information storage unit to store variation pattern information for each type indicating a temporal variation tendency of the number of visitors, for each of the types of the steady mobility facilities and the variable mobility facilities, wherein

the arithmetic means calculates an estimate value of the number of visitors within a predetermined period of time, the estimate value being calculated for the facility, and an estimate value of the number of visitors for each of time zones sectioning the predetermined period of time based on variation pattern information of the facility that is stored in the variation pattern information storage unit.

3. The population mobility estimation system according to claim 2, wherein

the first calculation basic information and the second calculation basic information include a coefficient for performing correction corresponding to an area on a calculation result of the estimate values of the number of visitors within the predetermined period of time.

4. The population mobility estimation system according to claim 3, wherein

the second calculation basic information of at least a part of types of facilities that belong to the variable mobility facilities is a calculation expression defined by a correlation between an actual survey value of a real number of visitors and the number of cars in a parking lot.

5. The population mobility estimation system according to claim 3, wherein

the second calculation basic information of at least a part of types of facilities that belong to the variable mobility facilities is a predetermined value based on an actual survey value of the number of visitors within a predetermined period of time.

6. The population mobility estimation system according to claim 3, wherein

the second calculation basic information of at least a part of types of facilities that belong to the variable mobility facilities is a calculation expression defined by a correlation between an actual survey value of a real number of visitors and a condition on a capacity of the facility.

7. The population mobility estimation system according to claim 3, wherein

the arithmetic means combines estimate values of the number of visitors for each of the time zones sectioning the predetermined period of time in a predetermined regional unit, the estimate values being calculated for each of the facilities, to calculate population mobility estimation data.

8. The population mobility estimation system according to claim 2, wherein

the first calculation basic information and the second calculation basic information include dwell-time information for each type on a period of time during which people stay in a day, and

the arithmetic means calculates population mobility potential that is an index value of potential population mobility, from the estimate value of the number of visitors for each of the time zones sectioning the predetermined period of time and the dwell-time information.

9. A population mobility estimation method, comprising:

storing, by a calculation basic information storage unit, first calculation basic information that is required for estimating the number of visitors to steady mobility facilities within a predetermined period of time, the steady mobility facilities serving as facilities where specific people come in and out routinely, and is obtained by further classifying the steady mobility facilities by type, and second calculation basic information that is required for estimating the number of visitors to variable mobility facilities within a predetermined period of time, the variable mobility facilities serving as facilities where unspecified people come in and out in a fluid manner, and is based on an actual survey value for each type obtained by further classifying the variable mobility facilities by type; and

extracting, by an arithmetic means, detailed information including at least a name of one of the facilities from map information, estimating a type of the facility based on the extracted name of the facility, and referring to the first calculation basic information or the second calculation basic information that corresponds to the type from the calculation basic information storage unit based on the estimated type, to calculate an estimate value of the number of visitors to the facility within a predetermined period of time.
