Abstract

To statistically analyze information on the path of ra movement of a moving body. An information analysis device includes a communication unit that receives position information for a vehicle, a memory unit that stores map information pertaining to roads over which the vehicle can travel and position information concerning facilities, a visit frequency calculator that calculates the frequency at which the vehicle visits a facility on the basis of facility information concerning the facility, and a travel path specification unit that specifies the vehicle that has made a plurality of visits to the facility on the basis of the results of calculations made by the visit frequency calculator and specifies the travel path to the facility for the specified vehicle from the position information and the map information pertaining to the roads.

Claims

1. An information analysis device, comprising:

a receiving unit that receives position information of a movable body;

a storage unit that stores information relevant to a road through which the movable body is capable of passing, and information relevant to a facility;

a visit frequency calculator that calculates a visit frequency of the movable body visiting the facility, on the basis of the position information of the movable body and the information relevant to the facility; and

a movement route identification unit that identifies the movable body that visits to the facility a designated plurality of times, on the basis of a calculation result of the visit frequency calculator, and, for the identified movable body, identifies a movement route from a start position to the facility on the basis of the position information and the information relevant to the road, thereby identifying a movement route of the movable body visiting the facility many times.

3. The information analysis device according to claim 1,

wherein the movement route identification unit further identifies a start position of the movable body, on the basis of the position information of the movable body, determines whether or not the identified start position exists in a predetermined range from the facility, on the basis of the identified start position and the information relevant to the facility, and identifies the movement route of the movable body to the facility by dividing the movement route into an in-predetermined range and an out-of-predetermined range.

4. The information analysis device according to claim 1,

wherein the storage unit further stores map information that is managed in a mesh-like predetermined region, and

the movement route identification unit further determines whether or not the movement route of the identified movable body to the facility is included in the mesh-like predetermined region for each mesh-like predetermined region, and outputs the movement route to be visible in accordance with the number of times in which the movement route to the facility is included in the mesh-like predetermined region.

2. An information analysis device, comprising:

a receiving unit that receives position information of a movable body;

a storage unit that stores information relevant to a road through which the movable body is capable of passing, and information relevant to a facility;

a visit frequency calculator that calculates a visit frequency of the movable body visiting the facility, on the basis of the position information of the movable body and the information relevant to the facility; and

a movement route identification unit that identifies the movable body of which a visit frequency to the facility is less than or equal to a predetermined number of times, on the basis of a calculation result of the visit frequency calculator, and, for the identified movable body, identifies a movement route from a start position to the facility on the basis of the position information and the information relevant to the road, thereby identifying a movement route of the movable body that has not visited the facility or has visited the facility once but not often after it last visited the facility.

5. An information analysis method performed by an information analysis device, the method comprising:

a receiving step of receiving position information of a movable body;

a storing step of storing information relevant to a road through which the movable body is capable of passing, and information relevant to a facility;

a visit frequency calculating step of calculating a visit frequency of the movable body visiting the facility, on the basis of the position information of the movable body and the information relevant to the facility; and

a movement route identifying step of identifying the movable body that visits to the facility a designated plurality of times, on the basis of a calculation result of the visit frequency calculating step, and, for the identified movable body, of identifying a movement route from a start position to the facility on the basis of the position information and the information relevant to the road, thereby identifying a movement route of the movable body visiting the facility many times.

6. An information analysis method performed by an information analysis device, the method comprising:

a receiving step of receiving position information of a movable body;

a storing step of storing information relevant to a road through which the movable body is capable of passing, and information relevant to a facility;

a visit frequency calculating step of calculating a visit frequency of the movable body visiting the facility, on the basis of the position information of the movable body and the information relevant to the facility; and

a movement route identifying step of identifying the movable body of which a visit frequency to the facility is less than or equal to a predetermined number of times, on the basis of a calculation result of the visit frequency calculating step, and, for the identified movable body, of identifying a movement route from a start position to the facility on the basis of the position information and the information relevant to the road, thereby identifying a movement route of the movable body that has not visited the facility or has visited the facility once but not often after it last visited the facility.
