Description

Information presentation device, information presentation method, and recording medium

The present disclosure relates to an information presentation device and the like that presents information regarding excess and shortage of supplies at an evacuation center.

When a disaster occurs, local governments take the lead in opening evacuation centers. At evacuation centers, evacuees and supplies are often managed using paper media. With paper media management, it is difficult to quickly identify surpluses and shortages of supplies. Therefore, it is necessary to accurately grasp information regarding excess and shortage of supplies at evacuation centers.

Patent Document 1 discloses a supply-demand matching system for providing goods and services (hereinafter referred to as goods, etc.) from supporters to requesters (disaster victims). The system of Patent Document 1 registers materials and the like (hereinafter referred to as permission targets) that are permitted to be provided from a supporter to a requester.

Embodiments for carrying out the present invention will be described below with reference to the drawings. However, although the embodiments described below include technically preferable limitations for carrying out the present invention, the scope of the invention is not limited to the following. In addition, in all the figures used for the description of the following embodiments, the same reference numerals are given to the same parts unless there is a particular reason. Furthermore, in the following embodiments, repeated explanations of similar configurations and operations may be omitted.

(First embodiment)
First, an information presentation device according to a first embodiment will be described with reference to the drawings. The information presentation device of this embodiment presents information regarding excess and shortage of supplies at a shelter based on information about evacuees and supplies at the shelter to be managed. When a plurality of shelters to be managed are opened, the information presentation device of this embodiment presents information regarding surplus and shortage of supplies for each shelter. For example, the information presentation device of this embodiment is built on a server or cloud. For example, the information presentation device of this embodiment may be constructed as a dedicated terminal device.

(composition)
FIG. 1 is a block diagram showing an example of the configuration of an information presentation device 10 according to the present embodiment. The information presentation device 10 includes an information acquisition section 11, a prediction section 12, and an output section 13.

The information acquisition unit 11 acquires evacuation information for each evacuation center. Evacuation information includes the number of evacuees. Further, the evacuee information may include the gender of the evacuees, the number of children, the number of infants, the number of elderly people, the number of disabled people, and the like.

FIG. 2 is a conceptual diagram for explaining an example of registering evacuee information of evacuees who have evacuated to an evacuation center. A terminal device 111, an input device 112, and a surveillance camera 113 are installed in the shelter. For example, the terminal device 111, the input device 112, and the surveillance camera 113 are placed at the entrance of a shelter. The terminal device 111, the input device 112, and the surveillance camera 113 are used to register evacuee information of evacuees who have evacuated to the evacuation center. For example, the terminal device 111, the input device 112, and the surveillance camera 113 may be placed inside a shelter. In this way, the terminal device 111, the input device 112, and the surveillance camera 113 can be utilized not only for registering evacuees who have evacuated to the evacuation center but also for managing evacuees at the evacuation center.

FIG. 2 shows a management device 100 that manages evacuee information at an evacuation center. For example, the management device 100 is constructed as a dedicated terminal installed at each evacuation center. For example, the management device 100 may be constructed on a server or a cloud. The management device 100 is connected to a terminal device 111, an input device 112, and a surveillance camera 113. Further, the management device 100 is connected to the information presentation device 10.

The management device 100 outputs the registered evacuation information to the information presentation device 10. The timing at which evacuation information is output to the information presentation device 10 can be set arbitrarily. For example, in response to input of new evacuation information, the management device 100 outputs registered evacuation information to the information presentation device 10. For example, in response to updating registered evacuation information, the management device 100 outputs the registered evacuation information to the information presentation device 10. For example, the management device 100 outputs the registered evacuation information to the information presentation device 10 at a preset timing.

For example, evacuation information input by an employee of a local government or the like is registered in the management device 100 via the terminal device 111. For example, the terminal device 111 may have a function of reading a code for accessing personal information attached to an evacuee's identification card or the like. Examples of such codes include matrix-type two-dimensional codes such as QR (Quick Response) codes (registered trademark) and stack-type one-dimensional codes such as barcodes. If there is a function to read such a code, the process of registering evacuees in the management device 100 and the process of managing evacuees using the management device 100 can be simplified.

For example, evacuation information input by an evacuee is registered in the management device 100 via an input device 112 installed for evacuation center management. In the example of FIG. 2, input device 112 has a touch panel. For example, the input device 112 may have a function of reading a code for accessing personal information attached to an evacuee's identification card or the like.

For example, the management device 100 may use facial recognition to identify a person extracted from an image taken by a surveillance camera 113 installed in an evacuation center, and register the identified information. Facial recognition can also be used to monitor the condition of evacuees inside evacuation centers. Furthermore, the management device 100 may identify evacuees according to the gait of the person extracted from the image captured by the surveillance camera 113.

In personal authentication using a code attached to an identification card, an individual is identified by possession of the identification card. However, in personal authentication using a code, there is a possibility that a person may impersonate another person by possessing another person's identification card or the like. Therefore, multiple personal authentication techniques may be combined to prevent an evacuee from impersonating another person. For example, biometric authentication based on physical characteristics such as the face, irises, fingerprints, veins, palm prints, and gait may be used as a personal authentication technique for identifying evacuees. For example, knowledge authentication that combines a personal identifier and a password may be used as a personal authentication technique for identifying evacuees. For example, as a personal authentication technique for identifying evacuees, lifestyle authentication according to behavioral patterns at an evacuation center may be used.

Additionally, the information acquisition unit 11 acquires material information for each evacuation center. For example, supplies include water, food, clothing, bedding, bath supplies, cleaning supplies, daily necessities, electrical appliances, entertainment products, luxury goods, and the like. For example, materials include cardboard, blue sheets, plastic bags, etc. For example, supplies include portable toilets, diapers, etc. The supplies may also include VR (Virtual Reality) goggles, ashtrays, supplies for people with disabilities, batteries, and the like. For example, the information acquisition unit 11 may include services in addition to goods. For example, services include various types of work such as electrical work, gas work, water work, air conditioning work, and repairs of various materials. For example, services include barbering, beauty, massage, and the like. The combination of goods and services is sometimes called the object of provision. In the following, when we refer to goods, we include services.

The quantity of supplies for each evacuation center is registered in the management device 100. For example, the quantity of supplies is registered in the management device 100 via the terminal device 111 by an employee of a local government or the like. For example, the quantity of supplies is registered in the management device 100 by an evacuee via the input device 112. For example, the quantity of supplies is registered in the management device 100 based on images taken by the surveillance camera 113. There are no particular limitations on the method of registering the quantity of supplies for each evacuation center in the management device 100.

The management device 100 outputs material information including the quantity of materials for each evacuation center to the information presentation device 10. The timing at which material information is output to the information presentation device 10 can be set arbitrarily. For example, in response to input of new material information, the management device 100 outputs registered material information to the information presentation device 10. For example, in response to updating registered material information, the management device 100 outputs the registered material information to the information presentation device 10. For example, the management device 100 outputs registered material information to the information presentation device 10 at a preset timing. Furthermore, the management device 100 may output evacuation information and material information to the information presentation device 10 at the same timing.

The prediction unit 12 acquires evacuation information and supply information for each shelter from the information acquisition unit 11. The prediction unit 12 predicts surplus and shortage of supplies for each evacuation center according to the acquired evacuation information and supplies information. The prediction unit 12 outputs information regarding surplus and shortage of supplies for each evacuation center (also referred to as surplus and shortage information). For example, the surplus/deficiency information includes information indicating whether the number of supplies is insufficient, sufficient, or excessive. For example, indicators of excess/deficiency information are insufficient, sufficient, and excessive. For example, the surplus/deficiency information indicates the current surplus/deficiency of supplies. For example, the surplus/deficiency information may indicate surplus/deficiency of supplies in the future. The surplus/deficiency information may include information on surplus/deficiency of supplies in similar disasters that occurred in the past. For example, similar disasters that have occurred in the past may have occurred in the same area or may have occurred in other areas.

The prediction unit 12 predicts surplus and shortage of supplies according to the number of supplies at the present time. For example, the prediction unit 12 may predict the surplus or shortage of supplies based on information on surplus or shortage of supplies in similar disasters that have occurred in the past. For example, two thresholds (a first threshold and a second threshold) are set for the number of materials. The first threshold is a threshold (quantity) for determining shortage/sufficiency of supplies. The second threshold is a threshold (quantity) for determining whether the material is sufficient or in excess. If the number of supplies is below the first threshold, there is a shortage of supplies. If the number of supplies is greater than or equal to the first threshold and less than or equal to the second threshold, then the supplies are sufficient. If the number of supplies exceeds a second threshold, the supplies are in excess. However, the threshold value set for the number of materials is not limited to two. The threshold value set for the number of materials may be set according to the number of indicators set for the number of materials.

The prediction unit 12 may predict the index (lack, sufficient, excess) of supplies according to the consumption amount according to the number of evacuees evacuated to the evacuation center. For example, the prediction unit 12 calculates the consumption amount of supplies by multiplying the number of evacuees accommodated in the evacuation center by the number of supplies required for each evacuee. The prediction unit 12 subtracts the amount of goods consumed according to the number of evacuees from the number of goods registered in the management device 100 to calculate the current excess or shortage of goods. The prediction unit 12 outputs a material index (insufficient, sufficient, surplus) according to the current surplus or shortage of materials.

The prediction unit 12 may predict the material index (shortage, sufficient, surplus) according to the number of days until the current material is consumed. For example, the prediction unit 12 calculates how many days' worth of consumption the current number of materials corresponds to by dividing the current number of materials by the daily consumption amount of materials. For example, two threshold values (a third threshold value and a fourth threshold value) are set for the number of days in which a material is consumed (also referred to as the number of consumption days). The third threshold is a threshold (date and time) for determining shortage/sufficiency of supplies according to the number of consumption days. The fourth threshold is a threshold (date and time) for determining whether supplies are sufficient or in excess according to the number of days of consumption. If the number of days the supplies are consumed is less than the third threshold, the supplies are in short supply. If the number of days for consumption of the supplies is greater than or equal to the third threshold and less than or equal to the fourth threshold, the supplies are sufficient. If the number of days the supplies are consumed exceeds the fourth threshold, the supplies are in excess. However, the threshold value set for the number of days for consumption of materials is not limited to two. The threshold value set for the number of days for consumption of materials may be set according to the number of indicators set for the number of days.

Information on surplus and shortage of supplies is not limited to the number of supplies or indicators set for the number of days for consumption of supplies (insufficient, sufficient, surplus). The index used by the prediction unit 12 as an index of excess or shortage of supplies may be set as appropriate depending on the type and scale of the disaster that has occurred. For example, the prediction unit 12 may predict the number of supplies and the number of days the supplies will be consumed as information on surplus and shortage of supplies.

The output unit 13 outputs the supply/deficiency information predicted by the prediction unit 12. Information on surplus and shortage of supplies includes information on surplus and shortage of supplies (insufficient, sufficient, excessive) for each evacuation center to be managed.

FIG. 3 is an example in which supply/deficiency information 131 of supplies is output to a terminal device 170 owned by a supporter or the like. For example, the surplus/deficiency information 131 is transmitted to the supporter's terminal device 170 by e-mail or the like. The surplus/deficiency information 131 includes surplus/deficiency information of supplies 1 to N regarding a plurality of shelters (shelter A, shelter B, . . . , shelter Z) (N is a natural number). The surplus/deficiency information 131 includes symbols indicating shortage (x), sufficient (○), and excess (◎). For example, supplies that are particularly in short supply may be highlighted. For example, supplies that are particularly in short supply can be highlighted by displaying them in an easy-to-identify color, in bold, blinking, or by changing the background of the text to a conspicuous color. good. For example, supplies that are in short supply may be displayed in a ranking format depending on the degree of shortage or necessity. If there is an evacuation center that is in short supply (x) of supplies, the supporter can select the evacuation center that is in short supply (x) as the evacuation center to which supplies should be sent. In addition, if there is an excess (◎) of the supplies at the evacuation center to which the supporter intended to send the supplies, the supporter may transfer the supplies to the evacuation center where the supplies are in short supply (x). You can choose as a place. For example, it is possible that supporters are sending too many supplies to any given evacuation center. In such a case, the supporter may cancel sending the supplies.

FIG. 4 is an example of displaying a user interface 151 on the supporter's terminal device 170 for requesting delivery of supplies to be sent. The user interface 151 displays information indicating which supplies are in short supply at which evacuation centers (also referred to as shortage information). The user interface 151 displays cells for inputting the shipping quantity of materials desired to be shipped. Additionally, the user interface 151 displays checkboxes for selecting the evacuation center to which supplies are to be sent. In the example of FIG. 4, the supporter wishes to ship 50 supplies N to evacuation center B. For example, a request for delivery of materials inputted into the user interface 151 is sent to a designated carrier by pressing a decision button (OK).

FIG. 5 is an example in which a carrier that responds to a delivery request from a supporter delivers supplies to an evacuation center designated by the supporter. For example, a carrier that receives a delivery request delivers a specified quantity of supplies to a specified evacuation center in response to the delivery request. For example, by creating a delivery plan based on surplus/deficiency information, a shipping company can deliver supplies in time for shortages. Additionally, the carrier may preferentially deliver supplies that are not currently in short supply at a certain evacuation center to other evacuation centers. For example, by deciding which carriers will deliver supplies to multiple evacuation centers, it may be possible to alleviate the situation where multiple carriers flood the evacuation centers. For example, it is possible for a carrier to deliver supplies to each evacuation center, taking into consideration traffic congestion along the delivery route.

The output unit 13 may present supply/deficiency information through a website that can be accessed by a terminal device owned by a supporter or the like. For example, the output unit 13 may record information on surplus and shortage of supplies in a database built on a server or cloud. Information on excess and shortage of supplies recorded in the database is accessed by users registered in advance.

FIG. 6 is an example in which future surplus/deficiency information (surplus/deficit information 132, surplus/deficit information 133) of supplies is output on a terminal device 170 owned by a supporter or the like. For example, the excess/deficiency information 132 and the excess/deficiency information 133 are transmitted to the supporter's terminal device 170 by e-mail or the like. The surplus/deficiency information 132 includes information regarding supplies that are expected to be in short supply at one of the evacuation centers in the next few days. In the example of FIG. 6, information such as "Evacuation center A is expected to run out of supplies 2 in one week" is displayed. Furthermore, in the example of FIG. 6, information such as "Evacuation Center B is expected to run out of supplies 1 in three days" is displayed. The surplus/deficiency information 133 includes surplus/deficiency information of supplies 1 to N regarding a plurality of shelters (shelter A, shelter B, . . . , shelter Z) (N is a natural number). The surplus/deficiency information 133 includes symbols indicating shortage (x), sufficient (○), and excess (◎) regarding supplies at the present time. In addition, the surplus/deficiency information 133 includes a symbol indicating the likelihood (△) of a shortage of supplies in the future. If there is an evacuation center that is in short supply (x) of supplies, the supporter can select the evacuation center that is in short supply (x) as the evacuation center to which supplies should be sent. In addition, if there is an excess (◎) of the supplies at the evacuation center to which the supporter intended to send the supplies, the supporter may transfer the supplies to the evacuation center where the supplies are in short supply (x). You can choose as a place. Supporters can also select evacuation centers that have supplies that are not currently in short supply (x) but are expected to be in short supply in the future (△) as evacuation centers to which supplies should be sent. For example, it is possible that supporters are sending too many supplies to any given evacuation center. In such a case, the supporter may cancel sending the supplies.

FIG. 7 is an example in which accompanying information 134 is displayed on a terminal device 170 owned by a supporter or the like in accordance with supply/deficiency information 135 of supplies. The accompanying information 134 in FIG. 7 includes information regarding foreign nationals who have evacuated. The accompanying information 134 is not particularly limited as long as it is information regarding an evacuation center. For example, the surplus/deficiency information 135 and the accompanying information 134 are transmitted to the supporter's terminal device 170 by e-mail or the like. The surplus/deficiency information 135 includes surplus/deficiency information of supplies 1 to N regarding a plurality of shelters (shelter A, shelter B, . . . , shelter Z) (N is a natural number). The surplus/deficiency information 135 includes symbols indicating shortage (x), sufficient (○), and excess (◎) regarding supplies at the present time. Further, the surplus/deficiency information 135 may include a symbol indicating a probability (△) of a shortage of supplies in the future.

The accompanying information 134 in FIG. 7 includes information regarding foreign evacuees. In the example of FIG. 7, the information "There are evacuees from country XXX. There is a shortage of ΔΔ unique to country XXX." is displayed on the supporter's terminal device 170. The supporter recognizes from the accompanying information 134 that some kind of supplies can be delivered to an evacuation center where evacuees from the same country are located. For example, evacuation centers may run out of country-specific supplies required by evacuees from a given country. It is assumed that such unique supplies would be difficult to procure at general evacuation centers. Such supplies may be in the possession of the evacuee and his or her supporter from the same country. In accordance with accompanying information 134, if supporters from the same country arrange to send supplies specific to their home country to evacuation centers where such supplies are in short supply, it is possible to resolve the shortage of such supplies. There is sex. For example, if you are a local government with a large population of people from a particular country, if you spread information that there is a shortage of supplies in that country, there is a possibility that supporters living in that country will arrange for the supplies. Further, the accompanying information 134 may include information on surplus or shortage of special supplies (food) that do not include ingredients that cannot be eaten by a particular religion. In this way, even special supplies that are difficult to obtain through general distribution channels may be easier to arrange.

The accompanying information 134 in FIG. 7 may include information specific to not only foreign countries but also domestic regions and districts. For example, when a disaster occurs in the Kanto region, the information presentation device 10 may present surplus/deficiency information regarding supplies specific to the Tohoku region. If they do so, there is a possibility that such supplies will be arranged by supporters living in the Tohoku region. For example, the information presentation device 10 may notify information regarding evacuees who have evacuated due to a disaster that has occurred in the country in different formats depending on whether they are in the country or abroad. By doing so, there is a possibility of receiving material support not only from within Japan but also from overseas. For example, the information presentation device 10 may be configured to notify domestically of information on shortages and shortages of supplies at evacuation centers where evacuees have taken refuge due to disasters that have occurred overseas. In this way, domestic supporters can provide relief supplies to evacuation centers overseas.

Even in domestic evacuation centers, evacuees from overseas may evacuate. In such cases, it is possible to imagine communication between the evacuation center operator and the evacuees from overseas. Therefore, the accompanying information 134 in FIG. 7 may include the evacuee's nationality and native language. If this is done, it may be possible to smoothly arrange communication tools such as translators and translation devices according to the nationality and native language of the evacuee.

FIG. 8 is an example in which the surplus/deficiency information 131 is displayed on a television (also referred to as a television) that can be viewed by supporters. In the example of FIG. 8, the output unit 13 outputs information on supply surplus and shortage to a server or the like that can be accessed by a terminal device of a broadcasting station that broadcasts television or radio. For example, broadcasting stations report information on shortages and shortages of supplies at each evacuation center through media such as television and radio. Supporters who check information on shortages and surpluses of supplies at each evacuation center through media such as television and radio can send the missing supplies to the evacuation center. The example of FIG. 8 may be applied not only to television and radio broadcasting stations, but also to operating stations of information sites that provide information on the Internet, and information dissemination media operated by local governments and private sectors. Further, the surplus/deficiency information 131 may be disseminated using not only video and audio media but also paper media such as newspapers. There are no particular limitations on the medium for presenting the excess/deficiency information 131.

FIG. 9 is an example of outputting information on surplus and shortage of materials to the terminal device 180 of a carrier that delivers the materials. Transport companies can deliver the necessary supplies to each evacuation center based on information on the surplus and shortage of supplies at each evacuation center. For example, transport companies may be assigned to each evacuation center depending on the occurrence of a disaster. In this way, carriers will be able to efficiently deliver supplies to evacuation centers, potentially reducing road congestion that can occur when supporters deliver supplies by car. For example, if the general public is informed that a delivery company has been assigned to each evacuation center, it may be possible to reduce unnecessary delivery of supplies by supporters among the general public.

Next, an example of the operation of the information presentation device 10 will be described with reference to the drawings. FIG. 10 is a flowchart for explaining an example of the operation of the information presentation device 10. In the explanation along the flowchart of FIG. 10, the information presentation device 10 will be explained as the main operating body.

In FIG. 10, the information presentation device 10 first obtains evacuation information and supply information for each evacuation center (step S11).

Next, the information presentation device 10 predicts supply/deficiency information for each evacuation center according to the acquired evacuation information and supply information (step S12).

Next, the information presentation device 10 outputs the predicted supply/deficiency information (step S13).

As described above, the information presentation device of this embodiment includes an information acquisition section, a prediction section, and an output section. The information acquisition unit acquires evacuation information including the number of evacuees for each evacuation center and supply information including the number of supplies for each evacuation center. The prediction unit predicts surplus/deficiency information regarding surplus/deficiency of supplies for each evacuation center according to evacuation information and supplies information. The output unit outputs the predicted surplus/deficiency information.

According to the information presentation device of this embodiment, by outputting surplus/deficiency information regarding supplies predicted according to evacuation information and supply information, the supporter can inform the supporter of the evacuation center to which the supplies the supporter wants to provide. can be presented appropriately.

Management staff working at evacuation centers are often busy responding to complaints from evacuees and are unable to grasp the situation at the site. Therefore, it is difficult for the management side to thoroughly manage inventory of supplies, consumption status, etc. According to the method of this embodiment, as long as the stock of supplies and the number of evacuees are known, the supporter can proceed with the arrangement of supplies, so that supplies that are in short supply at evacuation centers can be accurately supplied.

In one aspect of the present embodiment, the prediction unit predicts surplus/deficiency information of supplies determined for each evacuation center using indicators of shortage, sufficient, and excess. According to this aspect, it is possible to check whether there is an excess or shortage of supplies according to the indicators of shortage, sufficiency, and excess.

(Second embodiment)
Next, an information presentation device according to a second embodiment will be described with reference to the drawings. The information presentation device of this embodiment presents information regarding evacuation shelters (also referred to as evacuation shelter information) according to information on surplus and shortage of supplies for each evacuation shelter, in response to evacuation reservations made by evacuation targets.

FIG. 11 is a block diagram showing an example of the configuration of the information presentation device 20 according to the present embodiment. The information presentation device 20 includes an information acquisition section 21 , a prediction section 22 , a first output section 24 , an evacuation reservation acquisition section 25 , an evacuation center allocation section 26 , and a second output section 27 . The first output section 24 and the second output section 27 constitute the output section 23.

The information acquisition unit 21 has the same configuration as the information acquisition unit 11 of the first embodiment. The information acquisition unit 21 acquires evacuation information for each evacuation center. The information acquisition unit 21 also acquires material information for each evacuation center. The evacuation information and material information acquired by the information acquisition unit 21 are the same as those in the first embodiment.

The prediction unit 22 has a similar configuration to the prediction unit 12 of the first embodiment. The prediction unit 22 acquires evacuation information and supply information for each evacuation center from the information acquisition unit 21. The prediction unit 22 predicts surplus and shortage of supplies for each evacuation center according to the acquired evacuation information and supplies information. The prediction unit 22 predicts supply/deficiency information (lack, sufficient, excess) of supplies for each managed evacuation center. The prediction unit 22 outputs information regarding surplus and shortage of supplies for each evacuation center (also referred to as surplus and deficiency information) to the first output unit 24 and the evacuation center allocation unit 26.

The first output section 24 has a similar configuration to the output section 13 of the first embodiment. The first output unit 24 outputs information on supply surplus and shortage predicted by the prediction unit 22. Information on surplus and shortage of supplies includes information on surplus and shortage of supplies (insufficient, sufficient, excessive) for each evacuation center to be managed. The first output unit 24 may present supply/deficiency information on supplies through a website that can be accessed by a terminal device owned by a supporter or the like. For example, the first output unit 24 may record supply/deficiency information on a database built on a server or cloud. Information on excess and shortage of supplies recorded in the database is accessed by users registered in advance. For example, the first output unit 24 may notify the evacuation target person who requested the evacuation reservation of the surplus/deficiency information.

The evacuation reservation acquisition unit 25 acquires the evacuation reservations of the persons to be evacuated. For example, the evacuation reservation acquisition unit 25 acquires an evacuation reservation input via a terminal device (not shown) owned by the person to be evacuated. For example, a user interface for entering evacuation reservations is constructed to be accessible through a website.

The evacuation center allocation unit 26 acquires the evacuation reservation from the evacuation reservation acquisition unit 25. Further, the evacuation center allocating section 26 acquires supply/deficiency information for each evacuation center from the prediction section 22 . In response to the evacuation reservation, the evacuation center allocating unit 26 searches for an evacuation center that has sufficient supplies necessary for the evacuation target who requested the evacuation reservation. The evacuation center allocating unit 26 allocates the searched evacuation shelter to the evacuation target person who requested the evacuation reservation. The evacuation center allocating section 26 outputs information regarding the evacuation center (also referred to as evacuation center information) allocated to the evacuation target person who requested the evacuation reservation to the second output section 27 . Details of the evacuation center allocation by the evacuation center allocation unit 26 will be described later.

The second output unit 27 outputs shelter information regarding the shelter allocated by the shelter allocation unit 26. The evacuation information output from the second output unit 27 is notified to the evacuation target person who requested the evacuation reservation. For example, the evacuation center information includes the name, location, and number of people accommodated in the evacuation center. Further, the evacuation center information may include information on supplies and information on excess and shortage of supplies. For example, if there are insufficient supplies at the assigned evacuation center, the evacuee can bring the missing supplies with him and evacuate. For example, evacuees can bring extra supplies that are in short supply at their assigned shelters and distribute them to other evacuees.

FIG. 12 is a conceptual diagram summarizing the relationship of information acquired/provided by the information presentation device 20. For example, an evacuation reservation for a person to be evacuated is obtained from a mobile terminal 260 owned by the person to be evacuated. For example, evacuation information and supply information for each evacuation center are acquired from a management device (not shown) that manages the evacuation center to be managed. The information presentation device 20 notifies the evacuation target person who requested the evacuation reservation of evacuation shelter information including information regarding the allocated evacuation shelter. Further, the information presentation device 20 notifies the supporter's terminal device 270 of supply/deficiency information 230 for each evacuation center. The supply/deficiency information 230 for each evacuation center may be output to a mobile terminal 260 owned by the person to be evacuated. For example, a material search function according to the material surplus/deficiency information 230 for each evacuation center may be installed on the mobile terminal 260 owned by the person to be evacuated. For example, the supplies search function is constructed to enable searching for evacuation centers that have enough supplies for the evacuees and to which the evacuees can evacuate. In this way, the person to be evacuated can use the supplies search function to search for an evacuation center that has enough supplies for the person to be evacuated and where the person can evacuate. For example, the supply/deficiency information 230 may be presented through a website. Then, by using the search function of the website, the evacuee can search for an evacuation center that has enough supplies for the evacuee and where the evacuee can evacuate.

The mobile terminal 260 is a communication device that can be carried by an evacuee (user). For example, the mobile terminal 260 is a communication device having a communication function, such as a smartphone, a smart watch, or a mobile phone. The mobile terminal 260 transmits the evacuation reservation input by the evacuation target person to the information presentation device 20.

For example, the mobile terminal 260 may have a function of positioning the mobile terminal 260 using GNSS (Global Navigation Satellite System). For example, the mobile terminal 260 is equipped with a positioning function using GPS (Global Positioning System). The mobile terminal 260 generates position information of the mobile terminal 260 using positioning signals transmitted from artificial satellites such as GPS satellites and quasi-zenith satellites. The mobile terminal 260 transmits the generated position information to the information presentation device 20 together with the evacuation reservation. The location information of the mobile terminal 260 may be used to select evacuation center candidates. For example, the evacuation shelter allocating unit 26 narrows down the evacuation shelter candidates according to the location information of the evacuation target person who is the source of the evacuation reservation request. For example, the evacuation center allocating unit 26 selects evacuation shelters within a predetermined range from the location information of the evacuation target person who requested the evacuation reservation, as evacuation shelter candidates.

Additionally, the mobile terminal 260 receives evacuation information transmitted from the information presentation device 20. The mobile terminal 260 displays information regarding the evacuation center included in the received evacuation information on the screen of the mobile terminal 260. Here, it is assumed that an application that processes evacuation information transmitted from the information presentation device 20 is installed on the mobile terminal 260. For example, an application for providing supplies for general supporters may be built. By presenting evacuation centers in need of supplies through such an application, appropriate information can be shared and confirmed by many people on one platform. Such an application may be provided with a supplies search function according to the supply/deficiency information 230 of supplies for each evacuation center. For example, the supply/deficiency information 230 may be presented through a website. Then, general supporters can search for supply/deficiency information 230 using the search function of the website.

FIG. 13 is an example of a management table (evacuation reservation management table 235) used to manage evacuation reservations from people eligible for evacuation. The evacuation reservation management table 235 includes the number of evacuees and the number of evacuation reservations for each evacuation center. Furthermore, the evacuation reservation management table 235 includes information on surplus and shortage of supplies for each evacuation center. The supply/deficiency information includes the current surplus/deficiency information (upper row). In addition, the supply surplus/deficiency information includes surplus/deficiency information (in parentheses at the bottom) when the number of evacuees with evacuation reservations is added to the current number of evacuees. For example, if supplies are currently in excess (◎), adding the number of evacuees with evacuation reservations to the current number of evacuees will predict that supplies will be sufficient (○). For example, if supplies are currently sufficient (○), adding the number of evacuees with evacuation reservations to the current number of evacuees is predicted to result in insufficient supplies (△). The evacuation center allocating unit 26 allocates to the evacuation target person an evacuation center that does not lack necessary supplies even if the evacuation target person who is the source of the evacuation reservation request is added.

FIG. 14 is a conceptual diagram showing an example in which the evacuation information transmitted from the information presentation device 20 is displayed on the mobile terminal 260 of the person to be evacuated (user). In the example of FIG. 14, the information presentation device 20 generates evacuation information according to the location information of the mobile terminal 260 carried by the person to be evacuated in accordance with the evacuation reservation that includes the location information of the mobile terminal 260. do. Further, it is assumed that the person to be evacuated (user) needs the goods 1. For example, supplies necessary for a person to be evacuated (user) are estimated according to attributes such as gender and age of the person to be evacuated. For example, if the person being evacuated is a man, it is desirable to have enough supplies such as shaving equipment. For example, if the person being evacuated is a woman, it is desirable to have sufficient supplies such as cosmetics. For example, if the evacuees are children, it is desirable to have enough supplies such as sweets and games. For example, if the person to be evacuated is an elderly person, it is desirable to have enough supplies such as tea and sweets. For example, the supplies necessary for each person to be evacuated may be input in advance for each person to be evacuated. By pre-registering the supplies needed for each person to be evacuated, it is possible to select an evacuation center that has enough supplies to suit the preferences of the person being evacuated.

In the example of FIG. 14, evacuation shelter information including information regarding the evacuation shelter assigned to the evacuation target person (user) is displayed on the screen of the mobile terminal 260 of the evacuation target person (user). In the example of FIG. 14, information such as "There are enough supplies 1 at evacuation center A. Please evacuate to evacuation center A." is displayed on the screen of the mobile terminal 260. Furthermore, in the example of FIG. 14, an evacuation map including the route from the position of the mobile terminal 260 at the time of transmitting the evacuation reservation to the evacuation center is displayed on the screen of the mobile terminal 260. An evacuation target person (user) who confirms the evacuation information displayed on the screen of the mobile terminal 260 can evacuate to an evacuation center according to the evacuation information. Evacuation targets can reliably head to an evacuation center by checking the evacuation map while evacuating.

FIG. 15 is another example of a management table (evacuation reservation management table 236) used to manage evacuation reservations from people eligible for evacuation. The evacuation reservation management table 236 includes the number of evacuees and the number of evacuation reservations for each evacuation center. Furthermore, the evacuation reservation management table 235 includes information on surplus and shortage of supplies for each evacuation center. The supply/deficiency information includes the current surplus/deficiency information (upper row). In addition, the supply surplus/deficiency information includes surplus/deficiency information (in parentheses at the bottom) when the number of evacuees with evacuation reservations is added to the current number of evacuees. Further, the information on surplus and shortage of supplies includes information on surplus and shortage in accordance with the expected number of supplies in the future. For example, supplies 2 at evacuation center A are currently in short supply (×). However, after two days, supplies 2 at evacuation center A are expected to become surplus (◎). If the evacuation target person who requested the evacuation reservation needs the supplies 2, the evacuation shelter A cannot be assigned to the evacuation target person at this point in time. However, after two days, the evacuation shelter A can be assigned to the evacuation target. If the evacuation target person is not urgent to evacuate, the evacuation shelter allocation unit 26 may allocate a shelter to the evacuation target person who requested the evacuation reservation, according to the information on future surplus and shortage of supplies. For example, the evacuation center allocating unit 26 prevents evacuation centers that may have sufficient supplies at the moment but will not have enough supplies in the future to be allocated to evacuees who need those supplies. may be configured.

FIG. 16 is a conceptual diagram showing another example in which the evacuation information transmitted from the information presentation device 20 is displayed on the mobile terminal 260 of the person to be evacuated (user). In the example of FIG. 16, in response to an evacuation reservation that includes the location information of the mobile terminal 260 carried by the person to be evacuated, the information presentation device 20 generates evacuation information according to the location information of the mobile terminal 260. do. Further, it is assumed that the person to be evacuated (user) needs the goods 2.

In the example of FIG. 16, evacuation shelter information including information regarding the evacuation shelter assigned to the evacuation target person (user) is displayed on the screen of the mobile terminal 260 of the evacuation target person (user). In the example of FIG. 16, the information "There are enough supplies 2 at evacuation center A for two days. Please evacuate to evacuation center A in two days." is displayed on the screen of the mobile terminal 260. be done. Further, in the example of FIG. 16, an evacuation map including the route from the position of the mobile terminal 260 at the time of transmitting the evacuation reservation to the evacuation center is displayed on the screen of the mobile terminal 260. An evacuation target person (user) who has confirmed the evacuation information displayed on the screen of the mobile terminal 260 can evacuate to an evacuation center two days later according to the evacuation information. Evacuation targets can reliably head to an evacuation center by checking the evacuation map while evacuating.
