Guidance assistance apparatus, guidance assistance method, and storage medium for storing program

1. A guidance assistance method comprising:

acquiring a guidance route through which a guided person is to be guided from routes from a start-point position to an end-point position;

calculating, based on information relating to the routes, an influence level of deviation from the guidance route for each of branch places of the guidance route;

detecting a terminal device existing within a predetermined range from the branch place for which a maximum influence level is calculated;

determining, based on disposition information, a guiding person disposed to the branch place;

outputting information on the guiding person to the terminal device; and

outputting another information for guidance to another terminal device of the guiding person.

2. The guidance assistance method according to claim 1 , wherein

the another terminal device is configured to:

obtain information relating to a traffic volume; and

estimate the traffic volume based on the information obtained by a sensor.

3. The guidance assistance method according to claim 1 , wherein

the calculating includes calculating, as the influence level, a value based on a tendency for deviation from the guidance route to occur at a branch place and an influence of the deviation.

4. The guidance assistance method according to claim 3 , wherein

the influence level is further based on an influence of taking a route other than the guidance route.

5. The guidance assistance method according to claim 3 , wherein

the tendency is based on a traffic volume of the guidance route and a traffic volume of a route other than the guidance route.

6. The guidance assistance method according to claim 3 , wherein

the tendency is based on a probability of the deviation at the branch place, the probability depending on complexity of a structure of the branch place.

7. A guidance assistance system comprising:

at least one memory that stores instructions; and

at least one processor configured to execute the instructions to:

acquire a guidance route through which a guided person is to be guided from routes from a start-point position to an end-point position;

calculate, based on information relating to the routes, an influence level of deviation from the guidance route for each of branch places of the guidance route;

detect a terminal device existing within a predetermined range from the branch place for which a maximum influence level is calculated;

determine, based on disposition information, a guiding person disposed to the branch place;

output information on the guiding person to the terminal device; and

output another information for guidance to another terminal device of the guiding person.

8. The guidance assistance system according to claim 7 , wherein the another terminal device is configured to:

obtain information relating to a traffic volume; and

estimate the traffic volume based on the information obtained by a sensor.

9. The guidance assistance system according to claim 7 , wherein

the at least one processor is further configured to

calculate, as the influence level, a value based on a tendency for deviation from the guidance route to occur at a branch place and an influence of the deviation.

10. The guidance assistance system according to claim 9 , wherein

the influence level is further based on an influence of taking a route other than the guidance route.

11. The guidance assistance system according to claim 9 , wherein

the tendency is based on a traffic volume of the guidance route and a traffic volume of a route other than the guidance route.

12. The guidance assistance system according to claim 9 , wherein

the tendency is based on a probability of the deviation at the branch place, the probability depending on complexity of a structure of the branch place.

13. A non-transitory computer readable storage medium storing a program causing a computer to execute:

processing of acquiring a guidance route through which a guided person is to be guided from routes from a start-point position to an end-point position;

processing of calculating, based on information relating to the routes, an influence level of deviation from the guidance route for each of branch places of the guidance route;

processing of detecting a terminal device existing within a predetermined range from the branch place for which a maximum influence level is calculated;

processing of determining, based on disposition information, a guiding person disposed to the branch place;

processing of outputting information on the guiding person to the terminal device; and

processing of outputting another information for guidance to another terminal device of the guiding person.

14. The storage medium according to claim 13 , wherein

the another terminal device is configured to:

obtain information relating to a traffic volume; and

estimate the traffic volume based on the information obtained by a sensor.

15. The storage medium according to claim 13 , wherein

the processing of calculating calculates, as the influence level, a value based on a tendency for deviation from the guidance route to occur at a branch place and an influence of the deviation.

16. The storage medium according to claim 15 , wherein

the influence level is further based on an influence of taking a route other than the guidance route.

17. The storage medium according to claim 15 , wherein

the tendency is based on a traffic volume of the guidance route and a traffic volume of a route other than the guidance route.

18. The storage medium according to claim 15 , wherein

the tendency is based on a probability of the deviation at the branch place, the probability depending on complexity of a structure of the branch place.
