Information provision system, information provision method, and recording medium

1 . An information provision system, comprising:

at least one memory configured to store instructions; and

at least one processor configured to execute the instructions to:

collect, from a user terminal having an acceleration sensor, position information of the user terminal and behavior information indicating a movement behavior of the user terminal moving at an acceleration higher than a predetermined value, wherein a transmission of the behavior information from the user terminal is suppressed when the user terminal is located within predetermined indoor areas;

acquire an image from a camera installed around a road;

determine an occurrence of a user falling, slipping, or stumbling based on the behavior information and the image;

generate a danger level map based on the occurrence of the user falling, slipping, or stumbling, the danger level map indicating an attention-seeking place based on a position corresponding to the occurrence of the user falling, slipping, or stumbling on a predetermined map; and

provide the danger level map to another user terminal.

2 . The information provision system according to claim 1 , wherein the behavior information indicates a temporal change in acceleration that occurs in a movement behavior of the user terminal, the temporal change in the acceleration being measured by the acceleration sensor, and

the at least one processor is further configured to execute the instructions to:

generate the danger level map indicating the position corresponding to the occurrence of the user falling, slipping, or stumbling based on the temporal change in the acceleration.

3 . The information provision system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

generate the danger level map based on a number of times that behavior information of a plurality of user terminals is observed in a predetermined period.

4 . The information provision system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

collect the behavior information based on a forecast announcement, an observation of road surface freezing in a predetermined area associated with the predetermined map, or an observation of snowfall in the predetermined area associated with the predetermined map, and

generate the danger level map indicating the attention-seeking place at a time of the observation of the road surface freezing or the observation of the snowfall.

5 . The information provision system according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:

transmit an attention-seeking message to the another user terminal when the another user terminal is heading to the attention-seeking place on the danger level map.

6 . An information provision method, comprising:

collecting, from a user terminal having an acceleration sensor, position information of the user terminal and behavior information indicating a movement behavior of the user terminal moving at an acceleration higher than a predetermined value, wherein a transmission of the behavior information from the user terminal is suppressed when the user terminal is located within predetermined indoor areas;

acquiring an image from a camera installed around a road;

determining an occurrence of a user falling, slipping, or stumbling based on the behavior information and the image;

generating a danger level map based on the occurrence of the user falling, slipping, or stumbling, the danger level map indicating an attention-seeking place based on a position corresponding to the occurrence of the user falling, slipping, or stumbling on a predetermined map; and

providing the danger level map to another user terminal.

7 . A non-transitory computer-readable recording medium recording a program for causing an information provision system to execute:

processing of collecting, from a user terminal having an acceleration sensor, position information of the user terminal and behavior information indicating a movement behavior of the user terminal moving at an acceleration higher than a predetermined value, wherein a transmission of the behavior information from the user terminal is suppressed when the user terminal is located within predetermined indoor areas;

processing of acquiring an image from a camera installed around a road;

processing of determining an occurrence of a user falling, slipping, or stumbling based on the behavior and the image;

processing of generating a danger level map based on the occurrence of the user falling, slipping, or stumbling, the danger level map indicating an attention-seeking place based on a position corresponding to the occurrence of the user falling, slipping, or stumbling on a predetermined map; and

processing of providing the danger level map to another user terminal.
