Description

[Technical Field]

[0001] The present disclosure relates to a notification device or the like that notifies evacuation targets of a course of action. [Background technology]

[0002] When a disaster occurs, notifications are sent using emergency earthquake alerts, disaster prevention radio, and other notification methods. If evacuation is necessary, these notification methods encourage people in evacuation areas to evacuate. However, depending on the extent of the disaster damage, it may be better to wait at home. People in evacuation areas may not be able to determine whether it is safer to evacuate or wait at home, and may take the wrong action.

[0003] Patent Document 1 discloses a disaster prevention digital signage system. Under normal circumstances, the system of Patent Document 1 displays advertising content and the like on a digital signage device. When a disaster occurs, the system of Patent Document 1 interrupts the display of disaster prevention related information content on the digital signage device.

[0004] Patent Document 2 discloses a tsunami evacuation support device that supports users with communication terminals in evacuating from a tsunami. The device of Patent Document 2 sets scores for multiple indicators related to safety, taking into account the evacuation time of the evacuation target user based on the current location information, movement speed, map information, and predicted arrival time of the communication terminal. The device of Patent Document 2 calculates a safety prediction value indicating the degree of safety of each point on the map from the scores of the multiple indicators. The device of Patent Document 2 generates candidate evacuation sites for the evacuation target user based on the predicted safety values ​​of each point on the map. The device of Patent Document 2 also generates candidate evacuation routes from the current location of the communication terminal of the evacuation target user to the candidate evacuation sites based on the predicted safety values ​​of each point on the map. The device of Patent Document 2 transmits the generated candidate evacuation sites and candidate evacuation routes to the user's communication terminal via a network.

[0005] [Patent Document 1] Japanese Patent Publication No. 2020-030657 [Patent Document 2] Japanese Patent Application Laid-Open No. 2013-089078 Summary of the Invention [Problem to be solved by the invention]

[0006] The system of Patent Document 1 switches between a wide-area emergency notification mode and a local evacuation guidance mode depending on the disaster situation. Therefore, according to the system of Patent Document 1, if the location where a digital signage device is installed is an evacuation area, the digital signage device can display evacuation route guidance information to guide people in the vicinity to evacuation shelters, etc. However, the system of Patent Document 1 cannot provide disaster prevention information content or evacuation route guidance information to people who cannot refer to the digital signage device.

[0007] The device in Patent Document 2 can present potential evacuation locations and potential evacuation routes to a user who is a target of evacuation based on the current location information of the user's communication terminal. However, because the device in Patent Document 2 assumes that the user who is a target of evacuation will evacuate, there is a possibility that the device may encourage the user who is a target of evacuation to evacuate even when it would be safer for the user to wait at home or the like.

[0008] An object of the present disclosure is to provide a notification device or the like that can notify users in evacuation areas of safe behavior guidelines. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. However, the embodiments described below are limited in a manner that is technically preferable for carrying out the present invention, but the scope of the invention is not limited to the following. In all drawings used to describe the following embodiments, the same reference numerals are used for similar parts unless otherwise specified. Furthermore, in the following embodiments, repeated explanations of similar configurations and operations may be omitted.

[0015] (First embodiment) First, a notification device according to a first embodiment will be described with reference to the drawings. The notification device according to this embodiment presents a safe guide to a user based on damage information for the user and the area of ​​the evacuation shelter. For example, the notification device according to this embodiment is implemented on a server or in the cloud. For example, the notification device according to this embodiment may be implemented as a dedicated terminal device.

[0016] (composition) 1 is a block diagram showing an example of the configuration of a notification device 10 according to this embodiment. The notification device 10 includes a location information acquisition unit 11, a damage information acquisition unit 12, a safety level calculation unit 13, a behavioral guideline generation unit 15, and an output unit 17.

[0017] The location information acquisition unit 11 acquires location information of the user. For example, the location information acquisition unit 11 acquires location information of a mobile terminal owned by the user. If the user does not own a mobile terminal, the location information acquisition unit 11 acquires the address of the user's residence, which has been registered in advance, as the user's location information.

[0018] Furthermore, the location information acquisition unit 11 acquires location information of a shelter according to the location information of the user. For example, the location information acquisition unit 11 acquires location information of a shelter to which the user can take refuge, among shelters close to the user's location.

[0019] The damage information acquisition unit 12 acquires damage information about the user and the surrounding area of ​​the evacuation shelter according to the location information of the user and the evacuation shelter. For example, the damage information acquisition unit 12 acquires damage information about the user and the surrounding area of ​​the evacuation shelter from a disaster prevention system operated by a national or local government. For example, the damage information acquisition unit 12 may acquire damage information about the user and the surrounding area of ​​the evacuation shelter from a disaster prevention system of a fire station located near the user and the evacuation shelter. For example, the damage information acquisition unit 12 may acquire damage information about the user and the surrounding area of ​​the evacuation shelter from a disaster prevention system established by a private company. The damage information acquisition unit 12 may acquire not only current damage information but also future damage information predicted based on the current situation. For example, the damage information acquisition unit 12 acquires future damage information through a system that predicts possible disasters based on forecasts such as weather forecasts and tsunami forecasts. For example, the damage information acquisition unit 12 may acquire future damage information through a system that predicts possible disasters based on damage information in the area surrounding the user's current location.

[0020] The damage information acquisition unit 12 may acquire damage information about the user and the surrounding area of ​​the evacuation shelter according to the content posted on the social network. For example, the damage information acquisition unit 12 may acquire information linked to the place name of the district including the location of the user and the evacuation shelter from the content posted on the social network.

[0021] The damage information acquisition unit 12 may acquire damage information about users and the areas around evacuation shelters via an information posting platform established by each local government. For example, the information posting platform includes a message board operated by each local government and available on the Internet. The message board of the information posting platform can be viewed at will via the Internet. For example, the message board of the information posting platform may be configured so that only pre-registered users can post. Such a configuration can reduce the risk of fake news and the like being posted on the message board.

[0022] FIG. 2 is a conceptual diagram summarizing the relationships between pieces of information collected by the notification device 10. For example, user location information is collected from the mobile terminal 160 owned by the user. For example, evacuation shelter location information is acquired from information on the opening of evacuation shelters by local governments. For example, information on the opening of evacuation shelters is collected through notifications from local governments and reports from the media. For example, damage information around users and evacuation shelters is collected from national and local disaster prevention systems, sensors installed in cities, surveillance cameras installed on the streets, posts on social networks, etc.

[0023] The safety level calculation unit 13 calculates the safety level of an action that the user can take, based on damage information about the user and the area around the evacuation shelter. For example, the safety level is a score based on the degree of potential danger, the time until a dangerous state occurs, the duration of the dangerous state, and the like, related to the user's current location and the evacuation shelter. The safety level calculation unit 13 may also calculate the safety level of an action that the user can take, based on damage information about the area around the user and the evacuation shelter. For example, the safety level may be a score based on the danger level of a dangerous spot on the evacuation route the user takes to reach the evacuation shelter, the time the user spends in the dangerous spot, the number of times the user passes through the dangerous spot, and the like. The safety level calculation unit 13 may also calculate the risk level of an action that the user can take, instead of the safety level of the action that the user can take.

[0024] The risk level of a dangerous spot is ranked based on criteria such as whether some kind of damage has already occurred, whether there is a risk of some kind of damage occurring, or whether there is no risk of damage occurring. If some kind of damage has already occurred, the risk level is high. On the other hand, if there is no risk of damage occurring, the risk level is low. In other words, if some kind of damage has already occurred, the safety level is low, and if there is no risk of damage occurring, the safety level is high.

[0025] The longer you stay in a dangerous area, the lower your safety level, and the shorter the time you stay in a dangerous area, the higher your safety level. For example, an evacuation route along a river that is swollen due to heavy rain has a low safety level. For example, an evacuation route along a cliff where landslides may occur has a low safety level.

[0026] The more times a dangerous spot is passed, the lower the safety level, and vice versa. For example, an evacuation route that repeatedly passes over bridges over rivers that are swollen due to heavy rain has a low safety level. For example, an evacuation route that repeatedly passes near cliffs where landslides may occur has a low safety level.

[0027] Evacuation route R for the user to reach the evacuation shelter e Assume that there are n dangerous locations in the area (n is a natural number). The n dangerous locations are numbered 1 to n. The danger level at dangerous location n is expressed as D n , the time spent at the dangerous point n is T n , the number of times of passing through the dangerous point n is P n The degree of danger at the dangerous point n is D n may be a preset value or may be set according to the actual damage situation. For example, evacuation route R e The total risk value D in can be calculated using the following formula 1.

number

[0028] For example, evacuation route R e Safety level S e can be calculated using the following equation 2: S e =1 / D×100 (2) In the above equation 2, S e The larger the value, the higher the safety level. e However, the above formula 2 is only an example and does not limit the formula for calculating the security level.

[0029] Furthermore, the safety level calculation unit 13 calculates the safety level for the user's behavior. The safety level calculation unit 13 calculates the safety level at the user's location and the safety level at the location of the evacuation shelter. For example, the safety level calculation unit 13 calculates the inverse of the probability of damage occurring at the locations of the user and the evacuation shelter as the safety levels at those locations.

[0030] The safety level at the user's position is S u Let the safety level at the location of the evacuation shelter be S r1 For example, the safety level calculation unit 13 calculates the evacuation route R e Safety level S including r2 Calculate. S r2 =(S r1 -S e )×100···(3) However, when using the above formula 3, the safety level S r1 Safety level S e The safety level calculation unit 13 calculates the safety level S for each evacuation shelter and evacuation route. r2 Calculate.

[0031] The action guideline generation unit 15 generates an action guideline for the user according to the calculated safety level. The action guideline generation unit 15 generates an action guideline according to the safety level for actions that the user can take. For example, the action guideline generation unit 15 generates an action with the highest safety level as an action guideline. If there are multiple shelters, the action guideline generation unit 15 generates an action guideline for evacuating to the shelter with the highest safety level. If there are multiple routes to the shelter with the highest safety level, the action guideline generation unit 15 generates an action guideline for passing through the route with the highest safety level. If staying at the user's location provides the highest safety level, the action guideline generation unit 15 generates an action guideline indicating that it is better for the user to continue waiting.

[0032] The output unit 17 outputs the action guidelines generated by the action guideline generation unit 15. For example, the output unit 17 outputs the action guidelines to a mobile terminal 160 owned by the user. For example, the output unit 17 outputs the action guidelines to a household receiver owned by the user. For example, the output unit 17 may output the action guidelines to a television (also called a TV) or radio owned by the user. The user's safety is ensured when the user recognizes the action guidelines output from the notification device 10 and acts in accordance with the action guidelines.

[0033] (operation) Next, the operation of the notification device 10 will be described with reference to the drawings. Fig. 3 is a flowchart for explaining an example of the operation of the notification device 10. In the explanation following the flowchart of Fig. 3, the notification device 10 will be described as the subject of the operation.

[0034] In FIG. 3, first, the notification device 10 acquires the location information of the evacuation target person (user) (step S11).

[0035] Next, the notification device 10 acquires location information of evacuation shelters to which the evacuation target persons can take refuge (step S12).

[0036] Next, the notification device 10 acquires damage information in the vicinity of the evacuation target person (step S13).

[0037] Next, the notification device 10 calculates the safety level of actions that the evacuation target can take, based on the damage information in the vicinity of the evacuation target (step S14).

[0038] Next, the notification device 10 generates an action guideline for the evacuation target person according to the calculated safety level (step S15).

[0039] Next, the notification device 10 notifies the evacuation target person of the generated action guideline (step S16).

[0040] (Application example) Next, application examples of the notification device 10 according to the first embodiment will be described with reference to the drawings. Three application examples will be given here. The following application examples are merely examples and do not limit the application examples of the notification device 10 according to the first embodiment.

[0041] [Application example 1] 4 to 6 are conceptual diagrams for explaining Application Example 1. In Application Example 1, the user is notified of a course of action according to the relative degree of safety between the user's current location and the safety of evacuating to an evacuation shelter.

[0042] FIG. 4 is a conceptual diagram showing an example of an evacuation map used in Application Example 1. The evacuation map in FIG. 4 displays the user's location (current location) according to location information acquired from the user's mobile terminal 160. At the user's current location, the degree of safety resulting from the user remaining at that location is displayed. The evacuation map also displays the locations of evacuation shelters in the vicinity of the user's current location. At the locations of the evacuation shelters, the degree of safety resulting from the user evacuating to the evacuation shelter is displayed. The evacuation map also displays dangerous areas in the vicinity of the user's current location. For example, the evacuation map displays dangerous areas where there is a risk of flooding, landslides, building collapse, etc. For example, the evacuation map displays damage information regarding road closures in response to the occurrence of damage and whether bridges over rivers are passable.

[0043] In the evacuation map of FIG. 4, the safety level of the user's current location is 20. In contrast, the safety level of shelter X is 50, and the safety level of shelter Y is 80. In such a case, the notification device 10 notifies the user of a course of action to move to a location with a higher safety level. For example, the notification device 10 selects shelter X and shelter Y as candidate shelters with a higher safety level. The notification device 10 notifies the user of a course of action to evacuate to either shelter X or shelter Y. For example, the notification device 10 selects shelter Y as the shelter with the highest safety level. The notification device 10 notifies the user of a course of action to evacuate to shelter Y.

[0044] 5 is a conceptual diagram showing an example in which a guideline of action delivered from the notification device 10 is displayed on the mobile terminal 160 of a user who uses the notification device 10. In the example of FIG. 5, it is assumed that location information of the user's current location is transmitted from the mobile terminal 160 to the notification device 10, and a guideline of action corresponding to the location information is generated by the notification device 10.

[0045] The mobile terminal 160 is a communication device that can be carried by a user. For example, the mobile terminal 160 is a communication device with a communication function, such as a smartphone, a smartwatch, or a mobile phone. The mobile terminal 160 has a positioning function using the Global Navigation Satellite System (GNSS). For example, the mobile terminal 160 is equipped with a positioning function using the Global Positioning System (GPS). The mobile terminal 160 generates position information of the mobile terminal 160 using positioning signals transmitted from artificial satellites such as GPS satellites and quasi-zenith satellites. The mobile terminal 160 transmits the generated position information to the notification device 10.

[0046] The timing of generating / transmitting the location information by the mobile terminal 160 is not particularly limited. For example, the mobile terminal 160 generates / transmits the location information in response to a request from the notification device 10. For example, the mobile terminal 160 generates / transmits the location information at a preset timing. For example, the mobile terminal 160 generates / transmits the location information in response to detection of the occurrence of a specific disaster by an application installed on the mobile terminal 160. For example, the mobile terminal 160 generates / transmits the location information when information regarding the prediction of the occurrence of a specific disaster is acquired. If the location information is generated / transmitted when information regarding the prediction of the occurrence of a specific disaster is acquired, it becomes possible to issue an evacuation instruction at a stage before the occurrence of a disaster is detected.

[0047] The mobile terminal 160 receives a guideline of action corresponding to the location information of the mobile terminal 160 from the notification device 10. In this application example, it is assumed that an application for processing the guideline of action received from the notification device 10 is installed in the mobile terminal 160. Note that the mobile terminal 160 may be a device specialized for notifying the user of the guideline of action transmitted from the notification device 10.

[0048] In the example of FIG. 5, the screen of the user's mobile terminal 160 displays the safety levels of the user's current location and evacuation shelter, the safest action the user can take, and a course of action the user should take. The screen of the mobile terminal 160 displays the safety levels, such as "The safety level of the current location is 20. The safety level of evacuation shelter X is 50. The safety level of evacuation shelter Y is 80." In the example of FIG. 5, the user is recommended to evacuate. Therefore, the safety level of the evacuation shelter is calculated taking into account the risk level of the evacuation route. The screen of the mobile terminal 160 also displays the safest action the user can take, such as "It is safest to evacuate to evacuation shelter Y." The screen of the mobile terminal 160 also displays the course of action the user should take, such as "Please evacuate to evacuation shelter Y." Furthermore, in the example of FIG. 5, an evacuation map (FIG. 4) is displayed on the screen of the mobile terminal 160. For example, the screen of the mobile terminal 160 may display not only current damage information but also information such as a safety level based on future damage information. For example, information based on future damage information, such as "Please evacuate by XX:XX minutes," may be displayed on the screen of mobile terminal 160. For example, information based on future damage information, such as "This location will be flooded within XX minutes. Please evacuate within XX minutes," may be displayed on the screen of mobile terminal 160.

[0049] A user who has checked the information according to the action guidelines displayed on the screen of the mobile terminal 160 can improve their own safety by evacuating to shelter Y according to the action guidelines. By evacuating while checking the evacuation map (FIG. 4), the user can head to shelter Y while avoiding dangerous areas and areas where damage has occurred.

[0050] FIG. 6 is a conceptual diagram showing an example in which an action guideline distributed from the notification device 10 is notified via the individual household receiver 170 of the user using the notification device 10. In the example of FIG. 6, an action guideline corresponding to pre-registered location information of the user's residence, etc. is generated by the notification device 10. Note that the individual household receiver 170 may have a positioning function. In this case, the individual household receiver 170 generates / transmits location information of the mobile terminal 160 using a positioning signal transmitted from an artificial satellite such as a GPS satellite or a quasi-zenith satellite. The timing of generating / transmitting the location information by the individual household receiver 170 is not particularly limited.

[0051] The individual receiver 170 is a device that receives disaster prevention administrative radio broadcasts and outputs the received disaster prevention administrative radio broadcasts as audio. The individual receiver 170 has functions such as audio reception, emergency mass calling, selective calling, and recording and playback. For example, the individual receiver 170 has functions such as receiving sirens and music sounds, displaying text, and displaying a lamp for the hearing impaired. The individual receiver 170 can operate on both commercial power and built-in batteries. In the event of a power outage, the power source of the individual receiver 170 automatically switches from commercial power to the built-in batteries. For example, the individual receiver 170 can be connected to an antenna or speaker. For example, the individual receiver 170 has a function for transmitting data to a connected external device. The individual receiver 170 may be repurposed as long as it can receive disaster prevention administrative radio broadcasts and output the received disaster prevention administrative radio broadcasts as audio.

[0052] In the example of FIG. 6, the safety level of the user's current location and evacuation shelter, the safest action the user can take, and a course of action the user should take are notified by voice output from the individual household receiver 170 owned by the user. The individual household receiver 170 notifies the user of the safety levels by voice output, such as "The safety level of the current location is 20. The safety level of evacuation shelter X is 50. The safety level of evacuation shelter Y is 80." The individual household receiver 170 also notifies the user of the safest action the user can take by voice output, such as "It is safest to evacuate to evacuation shelter Y." The individual household receiver 170 also notifies the user of the course of action the user should take by voice output, such as "Please evacuate to evacuation shelter Y."

[0053] A user of the individual household receiver 170 may not own a mobile terminal 160. In such a case, it is not possible to display an evacuation map (FIG. 4) in real time, as is the case with the screen of the mobile terminal 160. For this reason, it is desirable to distribute evacuation maps, such as a map of the area around the user's residence and a disaster prevention map, to the user of the individual household receiver 170. The evacuation map displays the location of the user's residence and the location of evacuation shelters. The user of the individual household receiver 170 can check the evacuation map and evacuate to a shelter according to the action guidelines.

[0054] A device with a monitoring function (also called a monitoring device) may be installed in cooperation with the individual household receiver 170. For example, the monitoring device may be equipped with a camera or a motion sensor. For example, the individual household receiver 170 may detect that a user remains at home despite issuing a guideline recommending evacuation. In such a case, the individual household receiver 170 may make an individual call to the user who does not follow the guideline. For example, the individual household receiver 170 may be configured to notify the manager of an evacuation shelter or the like of the location of the user who does not follow the guideline.

[0055] [Application example 2] 7 to 9 are conceptual diagrams for explaining application example 2. In application example 2, a user is notified of an action guideline according to the relative degree of safety between the user's current location and the degree of safety of evacuating to a shelter. In application example 2, the user is notified of an action guideline including an evacuation route for evacuating to a shelter with a high degree of safety.

[0056] FIG. 7 is a conceptual diagram showing an example of an evacuation map used in Application Example 2. The evacuation map in FIG. 7 displays the user's location (current location) according to location information acquired from the user's mobile terminal 160. At the user's current location, a level of safety resulting from the user remaining at that location is displayed. The evacuation map also displays the locations of evacuation shelters in the vicinity of the user's current location. At the locations of the evacuation shelters, a level of safety resulting from the user evacuating to the evacuation shelter is displayed. The evacuation map also displays dangerous areas in the vicinity of the user's current location. For example, the evacuation map displays dangerous areas where there is a risk of flooding, landslides, building collapse, etc. For example, the evacuation map displays damage information regarding road closures in response to the occurrence of damage and whether bridges over rivers are passable. The evacuation map also displays safe evacuation routes from the user's current location to evacuation shelters with high safety levels.

[0057] In the evacuation map of FIG. 7, the safety level of the user's current location is 20. In contrast, the safety level of shelter X is 50, and the safety level of shelter Y is 80. In such a case, the notification device 10 notifies the user of an action guideline to move to a location with a higher safety level. For example, the notification device 10 selects shelter X and shelter Y as candidate shelters with a higher safety level. The notification device 10 also calculates the safety level of the route from the user's current location to the shelter. The notification device 10 generates an action guideline to evacuate to the shelter with the higher safety level of the route. In the example of FIG. 7, the notification device 10 generates an action guideline to evacuate to shelter Y. The action guideline in the example of FIG. 7 includes the following: The notification device 10 notifies the user of a course of action to evacuate to shelter Y. The evacuation route from the user's current location to shelter Y is shown by a solid line and arrows.

[0058] Fig. 8 is a conceptual diagram showing an example in which a guideline of action distributed from the notification device 10 is displayed on the mobile terminal 160 of a user who uses the notification device 10. In the example of Fig. 8, location information of the user's current location is transmitted from the mobile terminal 160 to the notification device 10, and a guideline of action corresponding to the location information is generated by the notification device 10. The mobile terminal 160 has the same configuration as in Application Example 1, and therefore a detailed description thereof will be omitted.

[0059] In the example of FIG. 8, the safety levels of the user's current location and shelter, the safest action the user can take, and a course of action the user should take are displayed on the screen of the user's mobile terminal 160. The screen of the mobile terminal 160 displays the safety levels, "The safety level of the current location is 20. The safety level of shelter X is 50. The safety level of shelter Y is 80." The screen of the mobile terminal 160 also displays the safest action the user can take, "It is safest to evacuate to shelter Y." The screen of the mobile terminal 160 also displays the course of action the user should take, "Please evacuate to shelter Y via evacuation route A." Furthermore, in the example of FIG. 8, an evacuation map (FIG. 7) is displayed on the screen of the mobile terminal 160. The evacuation map displays the evacuation route from the user's current location to shelter Y with solid lines and arrows.

[0060] A user who has checked the information according to the action guidelines displayed on the screen of the mobile terminal 160 can improve their own safety by evacuating to shelter Y according to the action guidelines. By checking the evacuation map (FIG. 7) and evacuating along evacuation route A, the user can head to shelter Y while avoiding dangerous areas and areas where damage has occurred.

[0061] 9 is a conceptual diagram showing an example in which an action guideline distributed from the notification device 10 is notified via a household receiver 170 of a user who uses the notification device 10. In the example of FIG. 9, an action guideline corresponding to pre-registered location information of the user's residence, etc. is generated by the notification device 10. The household receiver 170 has the same configuration as in Application Example 1, and therefore a detailed description thereof will be omitted.

[0062] In the example of FIG. 9 , the household receiver 170 owned by the user outputs a voice message to notify the user of the safety level of the user's current location and evacuation shelter, the safest action the user can take, and the course of action the user should take. The household receiver 170 outputs a voice message to notify the user of the safety levels, such as "The safety level of the current location is 20. The safety level of evacuation shelter X is 50. The safety level of evacuation shelter Y is 80." The household receiver 170 also outputs a voice message to notify the user of the safest action the user can take, such as "It is safest to evacuate to evacuation shelter Y via bridge C." The household receiver 170 also outputs a voice message to notify the user of the course of action the user should take, such as "Please evacuate to evacuation shelter Y via bridge C."

[0063] A user of the individual household receiver 170 may not own a mobile terminal 160. In such a case, it is not possible to display an evacuation map (FIG. 7) in real time, as on the screen of the mobile terminal 160. For this reason, it is desirable to distribute evacuation maps, such as a map of the area around the user's residence and a disaster prevention map, to the user of the individual household receiver 170. The evacuation map displays the location of the user's residence and the location of evacuation shelters. The evacuation map also displays key points on the route that may be used for evacuation. In the example of FIG. 9, a bridge over a river is displayed as a key point on the route. A user of the individual household receiver 170 can check the evacuation map and evacuate to a shelter via bridge C according to the action guidelines.

[0064] [Application example 3] 10 to 12 are conceptual diagrams for explaining Application Example 3. In Application Example 3, a user is notified of an action guideline according to the relative safety level between the safety level at the user's current location and the safety level of evacuating to an evacuation shelter. In Application Example 3, the user is notified of an action guideline to stay at home according to the safety level.

[0065] FIG. 10 is a conceptual diagram showing an example of an evacuation map used in Application Example 3. The evacuation map in FIG. 10 displays the user's location (current location) according to location information acquired from the user's mobile terminal 160. At the user's current location, the degree of safety resulting from the user staying at that location is displayed. The evacuation map also displays the locations of evacuation shelters in the vicinity of the user's current location. At the locations of the evacuation shelters, the degree of safety resulting from the user evacuating to the evacuation shelter is displayed. The evacuation map also displays dangerous areas in the vicinity of the user's current location. For example, the evacuation map displays dangerous areas where there is a risk of flooding, landslides, building collapse, etc. For example, the evacuation map displays damage information regarding road closures in response to the occurrence of damage and whether bridges over rivers are passable. In the example of FIG. 10, it is dangerous to cross bridges on the route from the user's location to the evacuation shelter.

[0066] In the evacuation map of FIG. 10, the safety level of the user's current location is 20. In contrast, the safety level of shelter X is 20, and the safety level of shelter Y is 20. The safety levels of shelter X and shelter Y are values ​​that include the safety level of the route from the user's location to the shelter. In such a case, the notification device 10 notifies the user of a course of action to stay at the current location.

[0067] 11 is a conceptual diagram showing an example in which a guideline of action distributed from the notification device 10 is displayed on the mobile terminal 160 of a user who uses the notification device 10. In the example of FIG. 11, location information of the user's current location is transmitted from the mobile terminal 160 to the notification device 10, and a guideline of action corresponding to the location information is generated by the notification device 10. The mobile terminal 160 has the same configuration as in Application Example 1, and therefore a detailed description thereof will be omitted.

[0068] In the example of FIG. 11, the safety levels of the user's current location and evacuation shelter, the safest action the user can take, and a course of action the user should take are displayed on the screen of the user's mobile terminal 160. The screen of the mobile terminal 160 displays the safety levels, such as "The safety level of the current location is 90. The safety level of evacuation shelter X is 20. The safety level of evacuation shelter Y is 20." The screen of the mobile terminal 160 also displays the safest action the user can take, such as "It is safest to wait at your current location." The screen of the mobile terminal 160 also displays a course of action the user should take, such as "Pay attention to disaster information and wait at your current location." Furthermore, in the example of FIG. 11, an evacuation map (FIG. 10) is displayed on the screen of the mobile terminal 160. The evacuation map displays damage information according to the risk level of bridges over rivers.

[0069] A user who has checked the information according to the action guidelines displayed on the screen of the mobile terminal 160 can maintain his / her own safety by waiting at his / her current location according to the action guidelines. By checking the damage information on the evacuation map (FIG. 10), the user can recognize that waiting at his / her current location is safer than evacuating. According to this application example, since the user can understand that waiting at his / her current location is safer, he / she can continue to stay at his / her current location with peace of mind.

[0070] 12 is a conceptual diagram showing an example in which an action guideline distributed from the notification device 10 is notified via a household receiver 170 of a user who uses the notification device 10. In the example of FIG. 12, an action guideline corresponding to pre-registered location information of the user's residence, etc. is generated by the notification device 10. The household receiver 170 has the same configuration as in Application Example 1, and therefore a detailed description thereof will be omitted.

[0071] In the example of FIG. 12, the household receiver 170 owned by the user outputs a voice message indicating the safety level of the user's current location and evacuation shelter, the safest action the user can take, and the guidelines for the user's actions. The household receiver 170 outputs the safety levels by voice, such as "The safety level of the current location is 90. The safety level of evacuation shelter X is 20. The safety level of evacuation shelter Y is 20." The household receiver 170 also outputs a voice message indicating the safest action the user can take, such as "It is safest to wait at your current location." The household receiver 170 also outputs a voice message indicating the guidelines for the user's actions, such as "Pay attention to disaster information and wait at your current location."

[0072] A user using the individual receiver 170 may not own a mobile terminal 160. In such cases, it is not possible to display the evacuation map (FIG. 10) in real time, as is the case with the screen of the mobile terminal 160. Therefore, it is effective to broadcast video of the area around the user's home in real time on the screen of a television (television 180) installed in the user's home. For example, the notification device 10 or the individual receiver 170 may be configured to switch the channel of the television 180 installed in the user's home to a program broadcasting disaster information. In the example of FIG. 12, video captured by a surveillance camera installed in the town around the user's home is displayed on the screen of the television 180. A user using the individual receiver 170 can check the screen of the television 180 and wait at home according to a course of action. For example, broadcasting a program that suits the user's preferences may ease the user's anxiety about waiting at home.

[0073] In the above application examples 1 to 3, the notification device 10 may reflect information posted through a social network (also referred to as supplementary information) on the evacuation map. For example, the notification device 10 may collect supplementary information corresponding to the area of ​​the evacuation map and display the supplementary information on the evacuation map in the form of text information, symbols, images, videos, etc. In cities with many social network users, more supplementary information can be collected, allowing for more accurate understanding of damage information.

[0074] The notification device 10 may collect supplementary information through an information sharing platform for residents established by a local government or the like. For example, the information sharing platform may be realized by a message board established for each local government. The information sharing platform can be accessed from a webpage dedicated to the local government and accepts information via a network. The information sharing platform allows members of the local government (staff and residents) to share the accepted information. In rural towns and villages with few social network users, it may be difficult to collect useful information from social networks. Therefore, it is useful to establish a message sharing platform for each local government. Furthermore, people from all over the world can post any information on social networks. Therefore, there is a possibility that the content posted on the social network may contain incorrect information. If a message sharing platform for each local government is established and configured so that only pre-registered users can post on the message board, the spread of incorrect information can be reduced.

[0075] Instead of the mobile terminal 160 or the individual receiver 170, a dedicated receiving device that receives information from the notification device 10 may be provided. For example, the dedicated receiving device may be a portable wearable device. The dedicated receiving device is preferably easily wearable, such as a bracelet or necklace. The dedicated receiving device is preferably portable, such as a pager or pedometer. By continuously outputting the action guidelines transmitted from the notification device 10 via audio from the dedicated receiving device, even users who do not own a mobile terminal 160 can continue to obtain appropriate action guidelines while evacuating. For example, new damage may occur during evacuation, and the safety level may be updated in real time. Even in such cases, if the action guidelines can be transmitted from the mobile terminal 160 or the dedicated receiving device, the user can act in accordance with the action guidelines and be provided with safety. Furthermore, by equipping the dedicated receiving device with an acceleration sensor, an angular velocity sensor, or a pulse sensor, the user's physical condition can be monitored. The notification device 10 may be configured to generate action guidelines according to the user's physical condition.

[0076] As described above, the notification device of this embodiment includes a location information acquisition unit, an evacuation information acquisition unit, a safety level calculation unit, an action guideline generation unit, and an output unit.
