Abstract

Claims (42)

1. An information processing device comprising hardware, software, or a combination of hardware and software that causes the information processing device to:

acquire position information of a mobile terminal;

acquire position information of a vehicle;

acquire movement means information of a holder of the mobile terminal;

determine a likelihood of collision between the holder of the mobile terminal and the vehicle at a crossing based on a position of at least one crossing included in stored road information, the position information of the mobile terminal, the position information of the vehicle, and the movement means information of the holder of the mobile terminal;

give a warning to at least one of the mobile terminal and a person in the vehicle based on a result of determination;

change a warning method depending on whether the holder of the mobile terminal is walking or riding on a two-wheel vehicle when the warning is given to the person in the vehicle; and

change a warning timing between when the holder of the mobile terminal is walking and when the holder of the mobile terminal is riding on the two-wheel vehicle.

2. The information processing device according to claim 1 , wherein the movement means information is information indicating a movement means identified by the mobile terminal held by the holder.

3. The information processing device according to claim 1 , wherein the hardware, the software, or the combination of hardware and software further causes the information processing device to:

acquire sensor information from the mobile terminal;

identify a movement means of the holder of the mobile terminal based on the sensor information; and

acquire the movement means information of the holder of the mobile terminal.

4. The information processing device according to claim 3 , wherein the hardware, the software, or the combination of hardware and software further causes the information processing device to determine whether the holder of the mobile terminal is walking or riding on the two-wheel vehicle using an artificial intelligence (AI) based on the sensor information.

5. The information processing device according to claim 1 , wherein the hardware, the software, or the combination of hardware and software further causes the information processing device to:

extract a predetermined crossing from the stored road information; and

determine the likelihood of collision between the holder of the mobile terminal and the vehicle at the extracted predetermined crossing.

6. The information processing device according to claim 5 , wherein the hardware, the software, or the combination of hardware and software further causes the information processing device to:

acquire crowd data and to extract a crossing at which a number of persons in a crowd is equal to or greater than a crowd threshold value based on the acquired crowd data; and

determine the likelihood of collision between the holder of the mobile terminal and the vehicle at the extracted crossing.

7. The information processing device according to claim 5 , wherein the hardware, the software, or the combination of hardware and software further causes the information processing device to:

acquire accident occurrence data and to extract a crossing at which a number of accidents occurring in a predetermined period is equal to or greater than an accident number threshold value based on the acquired accident occurrence data; and

determine the likelihood of collision between the holder of the mobile terminal and the vehicle at the extracted crossing.

8. The information processing device according to claim 5 , wherein the hardware, the software, or the combination of hardware and software further causes the information processing device to:

extract a crossing in an area in which a vehicle speed is limited to a predetermined speed; and

determine the likelihood of collision between the holder of the mobile terminal and the vehicle at the extracted crossing in the area.

9. An information processing method that is performed by an information processing device, the information processing method comprising:

acquiring position information of a mobile terminal;

acquiring position information of a vehicle;

acquiring movement means information of a holder of the mobile terminal;

determining a likelihood of collision between the holder of the mobile terminal and the vehicle at a crossing based on a position of at least one crossing included in stored road information, the position information of the mobile terminal, the position information of the vehicle, and the movement means information of the holder of the mobile terminal;

giving a warning to at least one of the mobile terminal and a person in the vehicle based on a result of determination in the determining of a likelihood of collision;

changing a warning method depending on whether the holder of the mobile terminal is walking or riding on a two-wheel vehicle when the warning is given to the person in the vehicle; and

changing a warning timing between when the holder of the mobile terminal is walking and when the holder of the mobile terminal is riding on the two-wheel vehicle.

10. A non-transitory storage medium storing a computer program causing a computer to perform:

acquiring position information of a mobile terminal;

acquiring position information of a vehicle;

acquiring movement means information of a holder of the mobile terminal;

determining a likelihood of collision between the holder of the mobile terminal and the vehicle at a crossing based on a position of at least one crossing included in stored road information, the position information of the mobile terminal, the position information of the vehicle, and the movement means information of the holder of the mobile terminal;

giving a warning to at least one of the mobile terminal and a person in the vehicle based on a result of determination in the determining of a likelihood of collision;

changing a warning method depending on whether the holder of the mobile terminal is walking or riding on a two-wheel vehicle when the warning is given to the person in the vehicle; and

changing a warning timing between when the holder of the mobile terminal is walking and when the holder of the mobile terminal is riding on the two-wheel vehicle.
