Description

[Technical field]

[0001] The present invention relates to an evacuation support device and an evacuation support system, and more particularly to an evacuation support device that distributes evacuation instruction information to target persons in the event of a disaster, and an evacuation support system including said device. [Background technology]

[0002] It is already known that in emergencies such as disasters, evacuation instruction information is distributed to people in disaster-stricken areas using information transmission means such as television and radio, or area mail, etc. For example, in Patent Document 1, a terminal at a public relations distribution center and a terminal device of a local resident are connected to a cloud server, and the cloud server receives an identification code of administrative information from the public relations distribution center and transmits the administrative information corresponding to the identification code to the terminal of the local resident. With such a system, public relations information suitable for residents in disaster-stricken areas can be distributed in the event of a disaster, ensuring the safety of the residents. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2022-131955 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, when instructing disaster victims to move (evacuate) to an evacuation destination, it is necessary to appropriately deliver instructions regarding the necessity and timing of evacuation, etc., taking into account the conditions of the evacuation destination and the route to the evacuation destination, etc. On the other hand, in conventional systems, including the system described in Patent Document 1, the information delivered to each person in the disaster area may be information with the same content, regardless of the location of the person or the condition of the evacuation destination. In such cases, it may be difficult to guide the disaster victims to the evacuation destination at the appropriate time and route.

[0005] Therefore, the present invention has been made in consideration of the above-mentioned problems, and its object is to provide an evacuation support device and an evacuation support system that will enable appropriate evacuation of target persons, taking into account the situation of the evacuation destination, etc., when a disaster occurs. [Means for solving the problem]

[0006] The above-mentioned problems are solved by the evacuation support device of the present invention by providing a first acquisition unit that acquires first information regarding the situation of an evacuation destination building in the event of a disaster, a second acquisition unit that acquires second information regarding the situation around the evacuation destination building in the event of a disaster, a generation unit that generates instruction information regarding evacuation to the evacuation destination building based on the first information and the second information in the event of a disaster, and a distribution unit that distributes the instruction information to people in the target area where the disaster occurred. The evacuation support device of the present invention configured as described above can send instructions to people in a target area regarding evacuation to a destination building based on the status of the destination building and the status of the surrounding area of ​​the destination building in the event of a disaster. This allows people in the target area to evacuate to the destination building appropriately and safely.

[0007] In addition, in the above-mentioned evacuation support device, the first acquisition unit may acquire, as the first information, information regarding at least one of the damage situation of the evacuation destination building in the event of a disaster, the environmental situation at the location of the evacuation destination building, and the results of measurements performed on the evacuation destination building at the time of the disaster. According to the above configuration, appropriate information can be acquired as information (first information) on the status of the evacuation destination building in the event of a disaster. As a result, more accurate information can be sent to people in the target area as evacuation instruction information.

[0008] In addition, in the above-mentioned evacuation support device, the first acquisition unit may acquire the first information based on at least one of a measurement value by a sensor installed in the evacuation destination building and an image captured by a camera installed at the location of the evacuation destination building. According to the above configuration, it is possible to obtain information with high reliability and objectivity as the first information, thereby improving the credibility of the instruction information generated based on the first information.

[0009] In addition, in the above-mentioned evacuation support device, the second acquisition unit may acquire, as the second information, at least one of information regarding the condition of roads to be used when heading to the evacuation destination building, the condition of neighboring buildings constructed around the evacuation destination building, and the condition of the water environment around the evacuation destination building. According to the above configuration, appropriate information can be acquired as information (second information) on the situation around the evacuation destination building in the event of a disaster. As a result, more accurate information can be sent to people in the target area as evacuation instruction information.

[0010] In addition, in the above-mentioned evacuation support device, the second acquisition unit may acquire the second information based on at least one of video footage captured by a camera installed in a location surrounding the evacuation destination building and posted information posted through a social networking service. According to the above configuration, real-time information on the situation around the evacuation destination building can be acquired as the second information, thereby improving the credibility of the instruction information generated based on the second information.

[0011] The evacuation support device of the present invention may further include a third acquisition unit that acquires third information related to at least one item of attributes of residents in the target area and houses of the residents in the target area. In this case, it is preferable that the generation unit generates instruction information based on the first information, the second information, and the third information when a disaster occurs, and the distribution unit distributes the instruction information to the residents in the target area. According to the above configuration, it is possible to send instructions to people in the target area regarding evacuation to evacuation destination buildings by further considering the attributes of the residents in the target area and information about their homes. This allows people in the target area to be evacuated to the evacuation destination more appropriately.

[0012] The evacuation support device of the present invention may further include a setting unit that sets a priority order for residents of the target area according to the third information acquired for the residents. In this case, the generating unit may generate information according to the priority order set for the residents of the target area as instruction information to be distributed to the residents of the target area. According to the above configuration, when evacuating residents of a target area, they can be evacuated according to the priority order set for each resident. This makes it possible to realize an accurate evacuation, such as giving priority to children, elderly people, etc.

[0013] In addition, in the above-mentioned evacuation support device, the generation unit may make a determination regarding at least one of whether or not to evacuate to the evacuation destination building, the route to travel to the evacuation destination building, and the timing of evacuation to the evacuation destination building based on the first information, the second information, and the third information, and generate instruction information according to the result of the determination. According to the above configuration, the instruction information is generated by reflecting the determination results regarding the possibility of evacuation to the evacuation destination building, the moving route to the evacuation destination building, and the timing of evacuation to the evacuation destination building. As a result, people in the target area can be evacuated to the evacuation destination building more appropriately.

[0014] In addition, in the above-mentioned evacuation support device, the generation unit may determine whether or not evacuation to a destination building is possible based on the first information, and if evacuation to the destination building is possible, determine a travel route and timing based on the second information and the third information. According to the above configuration, the determination performed when generating the instruction information is performed according to an appropriate procedure, which allows more accurate instruction information to be generated, and as a result, people in the target area can be evacuated to the evacuation destination more appropriately.

[0015] In the evacuation support device, the generation unit may perform a determination in association with residents of the target area and generate instruction information according to the result of the determination. In this case, the distribution unit may distribute the instruction information generated according to the result of the determination to residents associated with the determination among the residents of the target area. According to the above configuration, it is possible to send instruction information to each resident in accordance with the situation of each resident in the target area, taking into account that the situation of each resident (e.g., address, age, etc.) differs from resident to resident. This allows each resident to be evacuated appropriately, taking into account the situation of each resident.

[0016] In addition, in the above evacuation support device, when there are multiple evacuation destination buildings in the target area, the first acquisition unit may acquire first information about the multiple evacuation destination buildings, and the second acquisition unit may acquire second information about the multiple evacuation destination buildings. In this case, it is preferable that the generation unit selects an evacuation destination building from the multiple evacuation destination buildings according to people in the target area based on the first information and second information acquired about the multiple evacuation destination buildings, and generates instruction information regarding evacuation to the selected evacuation destination building. According to the above configuration, the most suitable building for people in the target area to evacuate to can be selected from among multiple evacuation buildings existing in the target area, and evacuation to that building can be appropriately guided.

[0017] In addition, the above-mentioned problem is solved by the evacuation support system of the present invention by having the above-mentioned evacuation support device and a client terminal that is used by people in the target area and outputs instruction information when it receives the instruction information. According to the above-mentioned evacuation support system, people in the target area can check the instruction information through the client terminal and evacuate to the evacuation building according to the instruction information. In other words, people in the target area can be appropriately evacuated to the evacuation building based on the situation of the evacuation building and the situation around the evacuation building in the event of a disaster. Effect of the Invention

[0018] According to the present invention, it is possible to realize an evacuation support device and an evacuation support system that, when a disaster occurs, takes into account the conditions of the evacuation destination and the like and appropriately evacuates target persons (people in a target area).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the evacuation assistance device and the evacuation assistance system of the present invention will be described by way of specific embodiments with reference to the accompanying drawings. In addition, since the basic data processing technologies (communication / transmission technology, data acquisition technology, data recording technology, data processing / analysis technology, image processing technology, machine learning technology, and visualization technology, etc.) required to implement the contents of the present invention are well-known technologies, explanations thereof will be omitted. In addition, the concept of "device" described in this specification includes a single device that performs a specific function by itself, as well as multiple devices that are distributed and exist independently but work together (in cooperation) to perform a specific function.

[0021] <<Outline of the evacuation support system>> First, an outline of an evacuation support system according to one embodiment of the present invention (hereinafter, this embodiment) will be described. The evacuation support system according to this embodiment (hereinafter, evacuation support system S) is a communication system constructed for the purpose of evacuating people in a target area, particularly residents of the target area, to an appropriate evacuation destination when a disaster occurs in the target area.

[0022] The target area is an area set as an area in which the services provided by the evacuation support system S can be used. Here, the "area" is, for example, an area under the jurisdiction of a local government as a unit of administrative division, and specifically, in Japan, a unit divided by a district division, prefecture, city, ward, town, village, block, house number, etc. The size, scope, etc. of the area set as the target area can be determined arbitrarily.

[0023] In this embodiment, the disasters are mainly assumed to be natural disasters such as earthquakes, typhoons, windstorms, heavy rains, heavy snowfall, tsunamis, floods, tornadoes, volcanic eruptions, landslides, and forest fires, but may also include specific man-made disasters such as air and water pollution (pollution), explosions in factories, etc., leakage of hazardous materials, nuclear accidents, and terrorist attacks. In other words, the present invention can be used when a natural disaster occurs in a target area, and can also be used when a specific man-made disaster occurs in a target area.

[0024] A user of the evacuation support system S is a person who is in the target area when a disaster occurs, for example, a resident of the target area, and the user can use the evacuation support service provided by the evacuation support system S through a client terminal 30 that the user owns, as shown in Fig. 1. Note that the users of the evacuation support system S may be all residents of the target area, or may be limited to residents of the target area who are registered as system users. On the other hand, the evacuation support system S is operated, for example, by a local government that has jurisdiction over the target area.

[0025] The evacuation support system S monitors the conditions of one or more observation points set in the target area, specifically, the weather conditions such as the amount of rainfall and wind speed at each observation point. Furthermore, when an abnormality or disaster occurs at an observation point, specifically, when a road near the observation point is flooded due to heavy rain or the like, or when a river near the observation point overflows, the evacuation support system S detects the abnormality. Furthermore, when an earthquake occurs in the target area, the evacuation support system S identifies the damage condition at each observation point from the conditions at each observation point, for example, the damage condition of houses and facilities at each observation point.

[0026] In addition, in the evacuation support system S, as shown in Fig. 1, when a disaster occurs in a target area, instruction information regarding evacuation is distributed to residents of the target area. The instruction information indicates the contents of instructions regarding evacuation to a building to which the evacuation destination is to be made (hereinafter referred to as evacuation destination building H), and specifically indicates whether or not evacuation to the evacuation destination building H is possible, the route to the evacuation destination building H, the timing of evacuation, etc. (see Fig. 3). The instruction information may also include the number of people that can be accommodated in the evacuation destination building H, the number of disaster supplies stored in the evacuation destination building H, and other information regarding the evacuation destination building H.

[0027] Residents of the affected area check the above instruction information through their client terminals and follow the instruction information to evacuate to the evacuation destination building H. This allows residents of the affected area to evacuate safely and smoothly.

[0028] Evacuation building H is a building constructed in the target area and has been designated in advance. In the following, an example will be described in which a logistics warehouse (hereinafter simply referred to as a warehouse) located in the target area has been designated as evacuation building H. To explain in more detail, it is assumed that there is a warehouse in the target area that has enough space to accommodate a large number of evacuees, that an agreement has been concluded between the management company of this warehouse and the local government of the target area, and that the warehouse is provided as evacuation building H. It is also assumed that disaster supplies are stored in the warehouse. Needless to say, the evacuation destination building H is not limited to a warehouse, but may be a building other than a warehouse (for example, a school, a public facility, or a factory).

[0029] In this embodiment, the instruction information distributed by the evacuation support system S is generated based on the situation at each point in the target area, the situation of the residents of the target area, etc. To be more specific, as shown in Fig. 1, the evacuation support system S collects information on the evacuation destination building H and its surroundings in the event of a disaster in the target area, the situation of the roads used when evacuating to the evacuation destination building H, and each resident of the target area and their place of residence, etc., and generates the instruction information based on this information.

[0030] This allows residents of the target area to be evacuated appropriately depending on the status of the evacuation building H, etc., when a disaster occurs in the target area. For example, if a warehouse, which is the evacuation building H, has suffered severe damage due to an earthquake (specifically, the warehouse's framework has been significantly deformed), it is possible to instruct people not to evacuate to the warehouse. In addition, when there are multiple routes to the evacuation building H, normally the route that can reach the evacuation building H in the shortest time is instructed, but if, for example, a problem such as flooding of the road occurs along the route, it is possible to instruct people to use a different route. Furthermore, it is possible to determine a priority order (i.e., an evacuation order) for each resident in the target area, so that the elderly and infants and their families are given priority in evacuation, and to instruct people to evacuate according to the determined priority order.

[0031] <<Example of evacuation support system configuration>> Next, a configuration example of the evacuation support system S will be described with reference to FIG. 2, the evacuation support system S includes an evacuation support device 10, a client terminal 30, a monitoring device, and an information providing server 50. The evacuation support device 10 is capable of communicating with the client terminal 30, the monitoring device, and the information providing server 50 via a communication network N such as the Internet or a mobile communication line. 2, for convenience of illustration, the number of client terminals 30 is only one, but in reality, the number of client terminals 30 may correspond to the number of residents in the target area. Also, in reality, the number of monitoring devices such as web cameras 38 may correspond to the number of observation points.

[0032] The evacuation support device 10 has a function of generating instruction information when a disaster occurs in a target area and distributing the generated instruction information to residents of the target area. The evacuation support device 10 is configured by a computer, and specifically, is configured by a server computer managed by a local government of the target area. However, the present invention is not limited to this, and the computer constituting the evacuation support device 10 may be a server computer managed by a private company or a public organization. Furthermore, the computer constituting the evacuation support device 10 is not limited to a server computer, and may be a personal computer (PC) or a workstation.

[0033] The client terminal 30 is used by residents of the target area, and has a function of receiving instruction information from the evacuation support device 10 and outputting the received instruction information. Specifically, as shown in Fig. 3, the client terminal 30 displays the instruction information on a display included in the client terminal 30 or a display connected to the client terminal 30. Residents of the target area can check the contents of the evacuation instruction by looking at the screen on which the instruction information is displayed. However, this is not limited to this, and for example, the client terminal 30 may be provided with a speaker, play back a sound indicated by the instruction information, and emit the played sound from the speaker to notify residents of the target area of ​​the evacuation instruction. The client terminal 30 may be configured as an information processing terminal that each resident personally owns and operates, specifically, a PC, a smartphone, a tablet terminal, etc. Alternatively, the client terminal 30 may be configured as a home server or the like installed in the house (house) where the resident of the target area lives.

[0034] The monitoring equipment is installed at designated locations in the target area, and includes, as shown in FIG. 2, an acceleration sensor 32 and a weather sensor 34 installed in evacuation building H, as well as a camera (warehouse camera 36) installed at the location of evacuation building H.

[0035] The acceleration sensor 32 is attached to the framework of the warehouse, which is the evacuation destination building H, and outputs a signal corresponding to the degree of deformation (more specifically, the story displacement angle) of the warehouse when an earthquake occurs. The acceleration sensor 32 may also be attached to secondary components such as the exterior walls and roof of the warehouse, in which case it outputs a signal corresponding to the acceleration and degree of deformation (more specifically, the amount of displacement) of the secondary components when an earthquake occurs. In this embodiment, the warehouse, which is the evacuation destination building H, has a multi-story structure, and the acceleration sensor 32 is attached to each floor of the warehouse's multiple floors. The acceleration sensor 32 attached to the floor of each floor outputs a signal corresponding to the acceleration and degree of deformation (more specifically, the story displacement angle) of the warehouse when an earthquake occurs. The weather sensor 34 detects the local weather conditions at the location of the evacuation destination building H, and outputs a signal according to the detection result. Here, the weather conditions detected by the weather sensor 34 may include the amount of precipitation, temperature, humidity, wind speed, and distance from the location of the lightning. The output signals from each of the above-mentioned sensors are transmitted to the evacuation support device 10 through the communication network N. The measurement results (measurement values) of the acceleration sensor 32 and the weather sensor 34 may be stored in a data logger (not shown), and the data logger may output a signal corresponding to the stored measurement value to the evacuation support device 10.

[0036] The in-warehouse camera 36 is a fixed camera that captures various parts of the warehouse, and captures the state of the warehouse in the event of a disaster in the target area. The video captured by the in-warehouse camera 36 is transmitted to the evacuation support device 10 via the communication network N.

[0037] The monitoring device may include a webcam 38 as an example of a camera. The webcam 38 is installed in a location around the evacuation destination building H (for example, around the site where the evacuation destination building H is built) and at each of a plurality of observation points set in the target area. The webcam 38 is a so-called live camera, and captures a certain range at the installation location of the webcam 38 as an angle of view, and distributes the captured image at the current time, that is, real-time image (live image). The webcam 38 installed in a location around the evacuation destination building H captures, for example, the condition of a road used when evacuating to the evacuation destination building H, and distributes the live image. The distributed live image is then transmitted to the evacuation support device 10 through the communication network N.

[0038] Furthermore, the monitoring equipment may include a house sensor 40 as a sensor installed in a nearby building (specifically, a nearby house) constructed around the evacuation destination building H. The house sensor 40 is, for example, an acceleration sensor, which is attached to each part of the frame of the nearby house and outputs a signal according to the acceleration and degree of deformation (specifically, the inter-story deformation angle) of the nearby house when an earthquake occurs. The output signal from the house sensor 40 is transmitted to the evacuation support device 10 through the communication network N. In addition, the neighboring buildings around the evacuation destination building H may be buildings other than houses, such as facilities or stores, and a sensor equivalent to the house sensor 40, i.e., an acceleration sensor, may be installed in these buildings and the output signal from the sensor may be transmitted to the evacuation support device 10.

[0039] The information providing server 50 provides information to the evacuation support device 10, and in particular, when a disaster occurs in a target area, provides information about the disaster through the communication network N. The information providing server 50 may include a server managed by a government agency or public institution such as the Meteorological Agency, or a private company that operates a weather-related business, and provides information about the weather in the target area (including weather forecast information). The information providing server 50 may also include a server for a social network service (hereinafter, SNS server). From this SNS server, posted information posted through SNS can be obtained, and when a disaster occurs in the target area, posted information related to the disaster is provided to the evacuation support device 10. Examples of posted information related to a disaster include posted information showing the state of a road used to evacuate to an evacuation destination building H, specifically, a state in which a road is flooded due to a heavy rain disaster, or a state in which a road is cut off due to an earthquake.

[0040] <<Detailed configuration of the evacuation support device>> Next, a detailed configuration of the evacuation support device 10 will be described. As described above, the evacuation support device 10 is configured by a computer, more specifically, a server computer (hereinafter, referred to as a server). Here, the evacuation support device 10 may be configured by one computer, or may be configured by multiple computers distributed in parallel. In addition, the server configuring the evacuation support device 10 may be a server for ASP (Application Service Provider), SaaS (Software as a Service), PaaS (Platform as a Service), or IaaS (Infrastructure as a Service).

[0041] The server constituting the evacuation support device 10 has substantially the same hardware configuration as a general server, and includes a processor 11, a memory 12, a storage 13, and a communication interface 14, as shown in FIG.

[0042] The processor 11 is composed of, for example, a CPU (Central Processing Unit), an MPU (Micro-Processing Unit), an MCU (Micro Controller Unit), a GPU (Graphics Processing Unit), a DSP (Digital Signal Processor), a TPU (Tensor Processing Unit), or an ASIC (Application Specific Integrated Circuit). The memory 12 is configured by semiconductor memories such as a Read Only Memory (ROM) and a Random Access Memory (RAM).

[0043] The storage 13 is configured, for example, by a flash memory, a hard disc drive (HDD), a solid state drive (SSD), a flexible disc (FD), a magneto-optical disc (MO disc), a compact disc (CD), a digital versatile disc (DVD), a secure digital card (SD card), or a universal serial bus memory (USB memory). The storage 13 may be built into the computer main body that configures the evacuation support device 10, or may be attached to the computer main body in an external form, or may be configured by an external server (for example, a database server or a file server) that exists on a network.

[0044] The communication interface 14 may be, for example, a network interface card, a communication interface board, etc. The server constituting the evacuation support device 10 can communicate with devices connected to the communication network N, that is, the above-mentioned devices constituting the evacuation support system S together with the evacuation support device 10, via the communication interface 14.

[0045] Moreover, in the server constituting the evacuation support device 10, a program for an operating system (OS) and an application program for evacuation support are installed as software.

[0046] Next, the configuration of the evacuation support device 10 will be described again from the functional aspect. As shown in Fig. 4, the evacuation support device 10 has functional units including a first acquisition unit 21, a second acquisition unit 22, a third acquisition unit 23, a setting unit 24, a generation unit 25, and a distribution unit 26. These functional units are realized by cooperation between hardware devices provided in a computer (server) constituting the evacuation support device 10 and software such as various programs installed in the computer. Each functional unit will be described below.

[0047] (1st acquisition part) The first acquisition unit 21 acquires first information related to the status of the evacuation destination building H in the event of a disaster. The first information is information necessary for generating instruction information, and as shown in Fig. 5, relates to at least one of the damage status of the evacuation destination building H in the event of a disaster, the environmental status at the location of the evacuation destination building H, and the results of measurements performed on the evacuation destination building H at the time of the disaster. In other words, the first acquisition unit 21 may acquire first information related to one or two of the damage status of the evacuation destination building H, the environmental status at the location of the evacuation destination building H, and the results of measurements performed on the evacuation destination building H at the time of the disaster, or may acquire first information related to all of these.

[0048] The damage status of the evacuation destination building H in the event of a disaster includes, for example, the damage status of the structure of the warehouse, which is the evacuation destination building H, and specifically, may include the degree of damage to the warehouse skeleton in the event of an earthquake, more specifically, the inter-story deformation angle of the skeleton, etc. When acquiring such first information, the first acquisition unit 21 can use the measurement results of each of the acceleration sensors 32 installed at multiple locations in the evacuation destination building H. That is, the first acquisition unit 21 may receive an output signal from each acceleration sensor 32, identify the measurement result by the acceleration sensor 32, i.e., the measured value of acceleration, from the received signal, obtain the inter-story deformation angle based on the identified acceleration, and acquire the value as the first information regarding the damage status (degree of damage) of the warehouse. The method of acquiring the first information on the degree of damage to the warehouse structure is not limited to the above, and the information may be acquired using the results of measurement by a sensor other than the acceleration sensor 32 (for example, a displacement meter).

[0049] Furthermore, the damage status of the evacuation destination building H in the event of a disaster may include the damage status of secondary members including the exterior walls and roof of the warehouse. When acquiring such first information, the first acquisition unit 21 may use the measurement results of each of the acceleration sensors 32 installed at multiple locations in the evacuation destination building H. In other words, the first acquisition unit 21 may receive an output signal from each acceleration sensor 32, identify the measurement results by the acceleration sensor 32, i.e., the acceleration, from the received signal, determine the amount of displacement of the exterior walls, roof, etc. based on the identified acceleration, and acquire the value as the first information regarding the damage status of the secondary members. The method of acquiring the first information on the damage status of the secondary components is not limited to the above, and may be acquired, for example, using the measurement results of the weather sensor 34 installed in the evacuation destination building H. Specifically, the wind speed measured by the weather sensor 34 may be identified, and the damage level of the exterior walls, roof, etc. may be calculated from the identified wind speed value, and the calculation result may be acquired as the first information on the damage status of the secondary components.

[0050] In addition, the damage situation of the evacuation destination building H in the event of a disaster may include, for example, the damage situation inside the warehouse, specifically, the toppled and broken situation of the equipment in the warehouse in the event of an earthquake, and the flooding situation inside the warehouse in the event of flood damage such as heavy rain. In addition, the damage situation inside the warehouse may also include the situation of a secondary disaster such as a fire that occurred in the warehouse due to an earthquake or the like. When acquiring such first information, for example, the first acquisition unit 21 may use a video image captured by the in-warehouse camera 36. That is, the first acquisition unit 21 may detect an abnormality in the warehouse by applying a publicly known image analysis technique and a scene recognition technique to the video image captured by the in-warehouse camera 36, ​​and acquire the detection result as the first information regarding the damage situation inside the warehouse.

[0051] The environmental conditions at the location of the evacuation destination building H may include, for example, weather information at the location of the evacuation destination building H, specifically, local rainfall, wind speed, and distance from a lightning source at the location of the evacuation destination building H. When acquiring such first information, for example, the first acquisition unit 21 may acquire the information using a measurement result by a weather sensor 34 installed in the evacuation destination building H. That is, the first acquisition unit 21 may acquire a weather-related value measured by the weather sensor 34 as the first information regarding the environmental conditions at the location of the evacuation destination building H. The method of acquiring the first information on the environmental conditions at the location of the evacuation destination building H is not limited to the above, and may be acquired, for example, by analyzing video captured by a webcam 38 installed outside the evacuation destination building H to identify the weather at the location of the evacuation destination building H. There are other methods of acquiring weather-related information, and the above information may be acquired, for example, by obtaining (downloading) weather data for the area including the evacuation destination building H from an information providing server of the Japan Meteorological Agency, which is one of the information providing servers 50.

[0052] The results of measurements made on the evacuation destination building H when a disaster occurs may include, for example, the measurement results from each of the acceleration sensors 32 installed at multiple locations in the evacuation destination building H. That is, the first acquisition unit 21 may receive output signals from each acceleration sensor 32, identify the measurement results from the acceleration sensors 32, i.e., the measurement values ​​of acceleration, from the received signals, and acquire the measurement values ​​as the first information.

[0053] (Second acquisition part) The second acquisition unit 22 acquires second information related to the situation in the vicinity of the evacuation destination building H in the event of a disaster. The second information is information necessary for generating instruction information, similar to the first information, and as shown in Fig. 5, relates to at least one of the situation of the road to be used when heading towards the evacuation destination building H, the situation of the neighboring houses (neighboring structures) constructed around the evacuation destination building H, and the situation of the water environment around the evacuation destination building H. In other words, the second acquisition unit 22 may acquire second information related to one or two of the situation of the road to be used for evacuation, the situation of the neighboring houses, and the situation of the water environment around the evacuation destination building H, or may acquire second information related to all of these.

[0054] The condition of the road to be used when heading to the evacuation building H may include, for example, the congestion condition (traffic jam condition) of the road in the event of a disaster in the target area, and the presence or absence of an abnormality on the road (specifically, flooding due to heavy rain or road severance due to an earthquake, etc.) and the damage condition thereof. When acquiring such second information, for example, the second acquisition unit 22 may use a video image captured by a webcam 38 installed in a location (specifically, the above-mentioned road) around the evacuation building H. That is, the second acquisition unit 22 may detect the traffic jam condition of the road, the presence or absence of an abnormality, etc. by applying a known image analysis technique and a scene recognition technique, etc. to the video image captured by the webcam 38, and acquire the detection result as the second information on the road condition.

[0055] The method of acquiring the second information on the condition of the road to be used when heading to the evacuation building H is not limited to the above, and for example, posted information posted through an SNS may be used. Specifically, posted information on the road leading to the evacuation building H is acquired from an SNS server, which is one of the information providing servers 50. In this case, a search using a keyword such as a hashtag may be performed as a method of acquiring information on the road leading to the evacuation building H from the posted information present in the SNS server. The acquired posted information may then be analyzed to identify the congestion status of the road, the presence or absence of an abnormality, and the like, thereby acquiring the above-mentioned second information. There are other methods for acquiring information regarding the congestion state (traffic jam state) of a road. For example, the information may be acquired from the Vehicle Information and Communication System Center (VICS) (registered trademark).

[0056] The status of the neighboring houses may include, for example, the damage status of the neighboring houses in the event of a disaster in the target area, specifically, the seismic intensity and the degree of damage of the neighboring houses in the event of an earthquake. When acquiring such second information, the second acquisition unit 22 may use the measurement results of the house sensor 40 installed in the neighboring houses. That is, the second acquisition unit 22 may receive an output signal from the house sensor 40, identify the measurement results of the house sensor 40, i.e., the measured value of acceleration, from the received signal, obtain an inter-story deformation angle based on the identified acceleration, and acquire the value as the second information on the damage status (degree of damage) of the neighboring angle. The method of acquiring the second information on the degree of damage of the neighboring houses is not limited to the above, and may be acquired using the measurement results of a sensor other than an acceleration sensor (for example, a displacement meter). Also, the number of neighboring houses for which the second information on the degree of damage is acquired may be set arbitrarily.

[0057] The state of the water environment around the evacuation destination building H may include, for example, fluctuations in the water level of rivers or lakes around the evacuation destination building H, the degree of flooding or rising water levels, and the collapse of levees, etc., in the event of a disaster in the target area, and, in the event that the evacuation destination building H is located near the coast, the presence or absence of a tsunami caused by an earthquake. When acquiring such second information, for example, the second acquisition unit 22 may use images captured by a webcam 38 installed in locations around the evacuation destination building H (specifically, points near rivers, lakes, and the sea around the evacuation destination building H). That is, the second acquisition unit 22 may apply known image analysis technology, scene recognition technology, and the like to the images captured by the webcam 38 to identify the current state of rivers, lakes, the sea, and the like around the evacuation destination building H, and acquire the identified state as the second information on the state of the water environment. The method of acquiring the second information on the condition of the road to be used when heading to the evacuation building H is not limited to the above. For example, information on the water environment around the evacuation building H may be searched and acquired from posted information present on an SNS server, and the second information may be acquired based on the acquired information.

[0058] (3rd acquisition part) The third acquisition unit 23 acquires third information related to residents of the target area. The third information is information necessary for generating instruction information, similar to the first information and the second information, and relates to at least one item of the attributes of the residents and the homes of the residents, as shown in Fig. 5. In other words, the third acquisition unit 23 may acquire third information related to any one of the attributes of the residents of the target area and the items related to the homes of the residents of the target area, or may acquire third information related to all of these. In this embodiment, the resident is a household, and the household includes a single-person household and a family household. However, the present invention is not limited to this, and the resident may be an individual.

[0059] Resident attributes may include, for example, the resident's age and gender, family structure for family households, whether or not there are infants or elderly people, whether or not there are anyone with a disease (chronic illness) or disability, and whether or not the resident owns a means of transportation such as a private car. Information about the home may include, for example, the location (address) of the home, the type of home (whether it is a detached house or an apartment complex such as a condominium), the age of the home, the structure (whether it is made of wood or reinforced concrete), and specifications.

[0060] The third acquisition unit 23 acquires the third information about each resident in the target area, for example, before a disaster occurs in the target area. The acquired third information is stored and accumulated in the storage 13 of the evacuation support device 10, and as a result, a resident information database DB shown in FIG. 2 is constructed in the storage 13. The method of acquiring the third information is not particularly limited, and for example, the third information may be acquired by a resident inputting information corresponding to the third information through an input device of the client terminal 30 and transmitting the input information to the evacuation support device 10. Alternatively, when a new resident moves into the target area, the local government of the target area may acquire the third information of the resident by registering the information of the resident through a registration terminal (not shown).

[0061] As shown in Fig. 5, the third information is stored in the resident information database DB in association with the name or identification ID of the resident. As shown in Fig. 5, the third information includes information for specifying a delivery destination (destination) when delivering instruction information to each resident, specifically, for example, the IP address of the client terminal 30 used by each resident or the email address of each resident.

[0062] (Settings section) The setting unit 24 sets a priority order for residents of the target area according to the third information acquired for the residents. The priority order is a priority order for evacuating to the evacuation destination building H when a disaster occurs in the target area, or more simply, an order of evacuation to the evacuation destination building H, and residents with higher priority are instructed to evacuate to the evacuation destination building H preferentially.

[0063] The setting unit 24 reads out the third information of each resident stored in the resident information database DB, and sets a priority order for each resident based on the read out third information according to a predetermined procedure. The procedure for setting the priority order is not particularly limited, but it is preferable to set the priority order according to the following procedure, for example. [How to set priority] - Residents (households) with infants and young children will be given higher priority. - Elderly residents who live alone will be given a higher priority. - Residents (households) with members with chronic illnesses will be given higher priority. The greater the distance from the evacuation destination building H to the resident's home, the higher (or lower) the priority for that resident is set.

[0064] When setting priorities, the structure and specifications (construction method) of each resident's home may be taken into consideration. For example, each resident's priority may be set based on the earthquake resistance of the home and whether or not it is fireproof.

[0065] (Generation part) When a disaster occurs in a target area, the generation unit 25 generates instruction information regarding evacuation to an evacuation destination building based on the first information acquired by the first acquisition unit 21 and the second information acquired by the second acquisition unit 22. In this embodiment, the generation unit 25 generates the instruction information based on the third information acquired by the third acquisition unit 23 (more specifically, the third information stored in the resident information database DB) together with the first information and the second information.

[0066] Furthermore, when generating the instruction information, the generation unit 25 performs a determination regarding at least one of whether or not evacuation to the evacuation destination building H is possible, the travel route to the evacuation destination building H (hereinafter also referred to as the evacuation route), and the timing of evacuation to the evacuation destination building H, based on the first information, the second information, and the third information. Particularly, in this embodiment, the generation unit 25 performs a determination regarding all of whether or not evacuation is possible, the evacuation route, and the timing of evacuation.

[0067] More specifically, the generation unit 25 performs a first judgment on the possibility of evacuation to the evacuation destination building H, based on the first information. In the first judgment, the generation unit 25 comprehensively judges whether or not evacuation to the warehouse is currently possible based on the damage situation of the evacuation destination building H indicated by the first information, specifically, the degree of damage to the structure of the warehouse, which is the evacuation destination building H, the damage situation of secondary components, and the damage situation inside the warehouse, to judge whether or not evacuation to the warehouse is currently possible.

[0068] Here, the judgment procedure in the first judgment will be explained by taking the case shown in Fig. 6 as an example. For example, in a case where an earthquake occurs in a target area as a disaster, if the degree of damage to the warehouse structure is small and there are no problems with the damage conditions of the secondary components and the interior of the warehouse, it is judged that evacuation to the warehouse is possible. Note that the evaluation of the degree of damage to the structure and the damage conditions of the secondary components (more specifically, the judgment of the magnitude) may be performed by comparing the degree of damage and the damage conditions with values ​​that are considered to be at normal levels (not problematic). On the other hand, if the damage situation inside the warehouse is severe, for example, if a fire has broken out inside the warehouse, it is determined that evacuation to the warehouse is not possible. In addition, if the damage to the warehouse structure is significant (more specifically, exceeds the expected level of damage), but there are no problems with the damage situation inside the warehouse, the possibility of evacuation will be determined depending on whether the damage to the structure exceeds a standard value (threshold value). In addition, if the damage to secondary components of the warehouse is severe but the damage inside the warehouse is not a problem, it is determined that partial evacuation (for example, evacuation to a specific location in the warehouse) is possible.

[0069] In the first determination, information other than the damage status of the evacuation destination building H, specifically, weather information at the location of the evacuation destination building H and the results of measurements made at the evacuation destination building H at the time of the disaster occurrence may be taken into consideration among the first information. For example, when it is determined that heavy rain is occurring at the location of the evacuation destination building H based on the weather information at the location of the evacuation destination building H, it may be determined that evacuation to the evacuation destination building H is impossible. Also, when the results of measurements made at the evacuation destination building H at the time of the disaster occurrence, for example, the measurement results by the acceleration sensor 32, exceed a reference value (threshold value), it may be determined that evacuation to the evacuation destination building H is impossible.

[0070] When it is determined in the first determination that evacuation to the evacuation destination building H is possible, the generation unit 25 performs a second determination regarding the evacuation route and the timing of evacuation based on the second information and the third information. In the second determination, the generation unit 25 determines the evacuation route and the timing of evacuation in consideration of the situation around the evacuation destination building H indicated by the second information (specifically, the situation of the roads used when heading to the evacuation destination building H and the situation of the water environment around the evacuation destination building H) and the information of the residents indicated by the third information.

[0071] Here, the judgment procedure in the second judgment will be described by taking the case shown in Fig. 7 as an example. For example, in a case where heavy rain has occurred in the target area as a disaster, the condition of the road (hereinafter simply referred to as the road) used to travel from the residents' houses to the evacuation destination building H and the condition of the river (hereinafter simply referred to as the river) around the evacuation destination building H are not particularly problematic. In this case, it is judged that the road can be used as an evacuation route and that evacuation is currently possible. On the other hand, if there are problems with both the road and river conditions (for example, if the river has overflowed and the road is submerged), it is determined that it is currently not possible to evacuate using that road. In addition, if the road conditions are poor but the river conditions are fine, it is determined that evacuation is currently possible by choosing another road (a detour road) as an evacuation route. In addition, if the river condition is bad but the road conditions are fine, it will be determined that evacuation is possible after waiting until the river situation calms down (for example, until the river water level drops from a dangerous level to a safe level).

[0072] In addition, the second judgment may take into account the second information, such as the condition of neighboring houses around the evacuation destination building H in the event of a disaster, specifically, the seismic intensity and damage condition of the neighboring houses. For example, since the specifications and structures of the warehouse, which is the evacuation destination building H, and the neighboring houses around it are different, the shaking of the warehouse may be greater than that of the neighboring houses. In this case, the second judgment determines that it is better to wait for a while before evacuating to the warehouse. In addition, while the infrastructure of nearby houses is shut down due to a disaster, the warehouse may be able to obtain power through an emergency power source, etc. In this case, the second judgment determines that it is currently possible to evacuate to the warehouse. Also, there may be cases where nearby houses are sufficiently stocked with disaster supplies, in which case the second judgment determines that there is no need to rush to evacuate to the warehouse and that it is acceptable to wait there for a while.

[0073] In the above manner, the generation unit 25 performs the first and second judgments. In the present embodiment, the generation unit 25 performs the first and second judgments for each resident in association with the resident of the target area. This is because the roads used when evacuating to the evacuation destination building H, the means of transportation to the evacuation destination building H, the travel time to the evacuation destination building H, and the presence or absence of rivers, etc. in the vicinity of the residence vary from resident to resident due to differences in the addresses of each resident, and as a result, the above judgment results may differ between residents.

[0074] Then, the generation unit 25 generates instruction information according to the results of the first judgment and the second judgment. In this embodiment, as described above, the first judgment and the second judgment are performed for each resident in association with each resident, so the generation unit 25 generates instruction information for each resident according to the results of the first judgment and the second judgment performed in association with each resident. In other words, when the generation unit 25 performs the first judgment and the second judgment for "resident X" among the residents of the target area, the generation unit 25 generates instruction information for "resident X" based on the judgment results obtained for "resident X."

[0075] In addition, in this embodiment, the generation unit 25 generates information according to the priority set for the residents of the target area by the setting unit 24 as instruction information to be distributed to each resident of the target area. Specifically, the generation unit 25 generates instruction information for each resident so that residents with higher priority are evacuated to the evacuation destination building H preferentially. For example, instruction information may be generated for residents with higher priority to instruct them to evacuate to the evacuation destination building H earlier than residents with lower priority. Alternatively, instruction information may be generated for residents with higher priority to evacuate via a movement route that allows smoother movement to the evacuation destination building H (for example, a road with less traffic congestion).

[0076] (Distribution Department) The distribution unit 26 distributes the instruction information generated by the generation unit 25 to people in the target area where the disaster has occurred, and more specifically, transmits the above instruction information to the client terminals 30 of each resident in the target area via the communication network N.

[0077] Furthermore, in this embodiment, as described above, the generation unit 25 performs the first and second judgments in association with each resident of the target area, and generates instruction information for each resident according to the results of these judgments. In response to this, the distribution unit 26 distributes the instruction information generated according to the results of the above judgments to the residents of the target area who are associated with the judgments. In other words, the instruction information generated based on the results of the judgment obtained for "resident X" is distributed by the distribution unit 26 to "resident X" (more specifically, to the client terminal 30 of "resident X").

[0078] In this embodiment, the content of the instruction information delivered to each resident is determined according to the results of the first and second judgments performed in association with each resident as described above, and the content is based on the priority of each resident, so that the content may differ between residents. In other words, unlike conventional area mail, the delivery unit 26 does not deliver instruction information with common content to each resident in the disaster-hit area, but delivers instruction information that is individually generated by reflecting the attributes and place of residence (house in which each resident lives) of each resident.

[0079] <<Example of information processing flow by the evacuation support system>> Next, an information processing flow for evacuation support by the evacuation support system S (hereinafter, evacuation support flow) will be described with reference to FIG.

[0080] The evacuation support flow proceeds according to the flow shown in Fig. 8, and specifically, each step shown in Fig. 8 is performed in the order shown in the same figure. Note that the flow shown in Fig. 8 is merely an example, and unnecessary steps may be deleted, new steps may be added, or the order of steps may be changed without departing from the spirit of the present invention.

[0081] Before the evacuation support flow begins, a server (hereinafter simply referred to as the server) constituting the evacuation support device 10 acquires third information in advance for each resident in the target area, and stores the acquired third information in storage 13 to construct a resident information database DB.

[0082] Then, when a disaster occurs in the target area, the evacuation support flow is started. More specifically, when the server receives early warning data of a disaster occurrence from a government agency or the like, this triggers the evacuation support flow to be started. The event that triggers the start of the flow is not particularly limited. For example, when a signal is received from a sensor (e.g., acceleration sensor 32 or house sensor 40) installed in a warehouse, which is the evacuation destination building H, or in a neighboring house, and the occurrence of a disaster is detected from the received signal, this may be used as a trigger to start the evacuation support flow.

[0083] When the evacuation support flow is started, first, the server acquires first information on the status of the evacuation destination building H in the event of a disaster occurring in the target area (S001). Specifically, the server receives the measurement results from the acceleration sensor 32 and the weather sensor 34 installed in the warehouse, which is the evacuation destination building H, and the video captured by the camera 36 inside the warehouse, via the communication network N. Then, the server acquires the first information on the damage status of the warehouse, etc., by executing analysis processing and calculation processing using the received measurement results and the captured video.

[0084] The server also acquires second information on the situation around the evacuation destination building H (warehouse) in the event of a disaster in the target area (S002). Specifically, the server receives video captured by a web camera 38 installed in a location around the evacuation destination building H via the communication network N, and analyzes the captured video to acquire second information on the situation of roads, water environment, etc. around the evacuation destination building H.

[0085] In step S002, the server may obtain posted information on the damage situation at each point in the target area from an information providing server 50 including an SNS server, etc., and may obtain the second information by analyzing the posted information. The server may also obtain the second information on the damage situation of the neighboring houses by receiving the measurement results by the house sensors 40 installed in the neighboring houses via the communication network N and executing analysis processing and calculation processing using the received measurement results.

[0086] Next, the server sets a priority order for each resident in the target area based on the third information stored in the resident information database DB (S003). Note that the step of setting a priority order for each resident may be performed in advance before the start of the evacuation support flow.

[0087] Thereafter, the server generates instruction information based on the acquired first information, second information, and third information. Specifically, the server performs a first determination using the first information to determine whether evacuation to the warehouse, which is the evacuation destination building H, is possible (S004). If it is determined that evacuation to the warehouse is possible, the process proceeds to step S006 and subsequent steps. On the other hand, if it is determined that evacuation to the warehouse is not possible, the server generates instruction information to prohibit / restrict evacuation to the warehouse (S005).

[0088] If it is determined that evacuation to the warehouse is possible, the server performs a second determination using the second information and the third information to determine a travel route (evacuation route) to the warehouse and the timing of evacuation (S006). Here, an example will be described in which there are two different travel routes R1 and R2 to the warehouse, and route R1 is a route with a shorter travel distance. If it is determined in the second determination that evacuation to the warehouse is currently possible using route R1, the server generates instruction information instructing evacuation to the warehouse using route R1 (S007).

[0089] On the other hand, if the second judgment determines that evacuation via route R1 is not currently possible, but evacuation via another route, route R2, is possible, the server generates instruction information instructing evacuation to the warehouse using route R2 (S008). In addition, if it is determined in the second judgment that evacuation is not currently possible using either of the two routes R1 or R2, the server generates instruction information instructing the user not to evacuate immediately but to wait for a while and then evacuate to the warehouse (S009).

[0090] The series of steps relating to the above-mentioned judgment and generation of instruction information, i.e., steps S004 to S009, are repeatedly performed for each resident in the target area (S010). In other words, the server performs the first judgment and the second judgment in association with each resident in the target area, and generates instruction information according to the judgment result. As a result, individual instruction information (i.e., instruction information for each resident) is generated for each resident in the target area.

[0091] Furthermore, when generating instruction information, particularly instruction information instructing evacuation to the warehouse (i.e., instruction information generated in step S007 or S008), the server generates instruction information according to the priority order set for each resident. Specifically, instruction information for each resident is generated so that residents with higher priority are evacuated to the warehouse first.

[0092] After generating the instruction information, the server distributes the instruction information to each resident in the target area, more specifically, transmits it to each resident's client terminal 30 (S011). At this time, the server distributes the instruction information for each resident to the corresponding resident. In other words, the server distributes the instruction information generated according to the results of the above-mentioned determination (first determination and second determination) to residents in the target area who are associated with the determination. Then, when the above-mentioned series of steps are all completed and the instruction information has been distributed to each resident in the target area, the evacuation support flow ends.

[0093] By implementing the evacuation support flow as described above, when a disaster occurs in the target area, each resident in the target area can receive instruction information from the evacuation support device 10. Then, each resident can appropriately evacuate to the warehouse, which is the evacuation destination building H, by checking the instruction information through the client terminal 30 and acting according to the instructions indicated by the instruction information. To explain in more detail, the possibility of evacuation to the warehouse is determined based on the damage condition of the warehouse and the weather at the location of the warehouse, and if it is determined that evacuation is possible, the residents are instructed to evacuate to the warehouse, and if it is determined that evacuation is not possible, evacuation to the warehouse is prohibited (restricted). In other words, in this embodiment, each resident can be evacuated to the evacuation destination after safety at the evacuation destination is ensured.

[0094] In this embodiment, the system determines the evacuation route and evacuation timing according to the conditions of the roads and water environment around the warehouse and the conditions of the houses nearby the warehouse, and generates instruction information based on the determination results. This allows each resident in the target area to be informed of the appropriate travel route and timing for evacuating to the warehouse, and as a result, each resident can evacuate to the warehouse more safely and smoothly.

[0095] In addition, in this embodiment, instruction information for each resident is generated taking into consideration the situation of each resident, specifically the attributes and address of each resident, etc. As a result, appropriate instruction information for each resident can be sent to each resident, taking into consideration that the situation of each resident in the target area differs from resident to resident. Specifically, since the road that each resident uses when evacuating to the warehouse may vary depending on the resident's address, it is possible to set an appropriate evacuation route according to the address of each resident, taking this into consideration, and to distribute instruction information instructing the resident to evacuate to the warehouse using the set route. In addition, it is possible to determine the degree of necessity of evacuation to the warehouse, taking into consideration the supply status of infrastructure in each resident's house, the number of stockpiled goods, etc., and distribute instruction information according to the determination result. As a result of the above, residents can be appropriately evacuated to warehouses based on their circumstances (specifically, their addresses, etc.).

[0096] Furthermore, in this embodiment, priorities are set for the residents of the target area, and when evacuating the residents of the target area, instruction information is generated to evacuate each resident according to their priority. This allows each resident to be evacuated to the warehouse in a rational and appropriate manner, for example by prioritizing the evacuation of children and the elderly.

[0097] <<Example of implementation when there are multiple evacuation buildings>> In the embodiment (present embodiment) described above, it is assumed that only one evacuation destination building H exists (is installed) in the target area, but this is not limited to this. In other words, a case (hereinafter, a modified example) in which multiple evacuation destination buildings H exist in the target area is conceivable. In such a modified example, it is preferable that the evacuation support device 10 selects an appropriate (optimal) evacuation destination building H from among the multiple evacuation destination buildings H for each resident, generates instruction information regarding evacuation to the selected evacuation destination building H, and distributes it to each resident.

[0098] Specifically, when a disaster occurs in a target area where multiple evacuation destination buildings H exist, the evacuation support device 10 (more specifically, the first acquisition unit 21) acquires first information about each of the multiple evacuation destination buildings H, as shown in Fig. 9. The evacuation support device 10 (more specifically, the second acquisition unit 22) acquires second information about the situation around the building for each of the multiple evacuation destination buildings H. The evacuation support device 10 (more specifically, the third acquisition unit 23) acquires third information about residents of the target area, as in the present embodiment, and accumulates the acquired third information in the storage 13 to construct a resident information database DB.

[0099] In the modified example, the evacuation support device 10 (more specifically, the generation unit 25) selects one evacuation destination building H from among the multiple evacuation destination buildings H based on the first information and second information acquired about the multiple evacuation destination buildings H and the third information about the residents of the target area. The evacuation destination building H selected at this time is a building that corresponds to the situation of the residents of the target area, for example, the building closest to the address of the residents. Note that the selection criteria for the evacuation destination building H may be determined arbitrarily. Thereafter, the evacuation support device 10 (more specifically, the generation unit 25) generates instruction information regarding evacuation to the selected evacuation destination building H, and distributes the generated instruction information to residents in the target area. Note that in the modified example, the instruction information is generated according to a procedure substantially similar to that of the present embodiment.

[0100] Selection of the evacuation building H and generation and distribution of instruction information are performed for each resident in the target area. As a result, an evacuation building H according to each resident's situation (more specifically, address) is selected, and instruction information instructing the resident to evacuate to the selected evacuation building H is distributed to the resident. As a result, when a disaster occurs in the target area, each resident in the target area can be instructed to evacuate to the evacuation building H that is optimal for that resident (for example, the building that is closest to the resident's home and easiest to travel to), allowing each resident to evacuate more appropriately. The modified example is similar to the present embodiment except for the above-mentioned configuration, and provides the same effects as the present embodiment.

[0101] <<Other embodiments>> Although one embodiment of the evacuation support device and the evacuation support system of the present invention has been described above, the above embodiment is merely an example for facilitating understanding of the present invention and does not limit the present invention. In other words, the present invention may be modified or improved without departing from the spirit of the present invention. In addition, the present invention naturally includes its equivalents.

[0102] Regarding another embodiment of the present invention, for example, when generating instruction information, the first information and the second information are used, but the third information does not necessarily have to be used. However, when the third information is used, more appropriate instruction information that matches the situation of each resident can be delivered based on the attributes of each resident in the target area and information on the house in which each resident lives. In this respect, the above-mentioned embodiment is more advantageous.

[0103] In the above embodiment, the instruction information is delivered to residents of the target area, but the present invention is not limited to this. For example, the instruction information may be delivered to people who are in the target area when a disaster occurs in the target area, such as people who work in the target area and people who happen to be in the target area when the disaster occurs. In this case, information on the current locations of these people (current location information) may be obtained using a GPS (Global Positioning System) or the like, and instruction information for the above people may be generated based on the current location information, the first information, and the second information.

[0104] In the above embodiment, the computer constituting the evacuation support device 10 is configured as a server managed and used by a local government in the target area, but this is not limited to this. For example, the evacuation support device 10 may be configured as a server operated by a private company or an individual.

[0105] In the above embodiment, fixed cameras (specifically, the warehouse camera 36 and the web camera 38) are installed at the location of the evacuation destination building H and at locations around the evacuation destination building H, and the first information and the second information are acquired based on the images captured by these cameras. However, instead of or in addition to this, a satellite image that visualizes observation data from a sensor (not shown) mounted on an earth observation satellite may be acquired, and the first information and the second information may be acquired based on the satellite image.

[0106] Furthermore, the evacuation support device 10 may further include other functions in addition to the above-mentioned functions, i.e., obtaining information necessary for generating instruction information, generating and distributing instruction information. For example, the device may include a function of predicting the occurrence of a disaster and executing a process (e.g., warning, etc.) according to the prediction result. Specifically, for the weather in the target area, forecast data (forecast values) obtained from the Meteorological Agency and the like and measurement data (actual values) at multiple observation points installed in the target area are collected and accumulated over a long period of time, and a comparison result between the accumulated forecast values ​​and the actual values ​​is analyzed. Through this analysis, a model for predicting local weather at each observation point is constructed from the forecast data of the weather in the target area. Then, based on the local weather predicted by this model, for example, when it is predicted that the weather at each observation point will be one that may cause a disaster (e.g., heavy rain, etc.), an alert is issued to residents of the target area.
