Description

  The present invention relates to an evacuation action support system that provides information for supporting an evacuation action to a user terminal in a situation where a disaster such as storm and flood damage may occur, and a server device thereof.

  Japan is often attacked by typhoons, heavy rains, heavy snowfalls, earthquakes, eruptions, etc. that trigger natural disasters, and the topography itself is complex and steep, and the geology is brittle, making it vulnerable to natural disasters. have. In order to prevent disasters, it is also necessary to provide disaster prevention facilities to prevent disasters themselves, but it is important to evacuate residents in hazardous areas before disasters occur. In this case, if there is a delay in evacuation, there are cases where the life is lost.

  On the other hand, as means for providing disaster information related to storm and flood damages, news media through mass media such as television broadcasting and radio broadcasting and information distribution using the Internet have been widely used. Since these means are intended to make information widely available to the general public, information of the same content is provided to all people at the same time. However, there are many types of disasters that are likely to occur, and these vary depending on the geographical conditions. For example, residents in the vicinity of rivers need to be careful about river flooding, and those in mountainous areas should be aware of landslides, landslides, and avalanches. Also, the time required for evacuation varies depending on not only geographical conditions but also human conditions. For this reason, it is necessary to provide information necessary for residents to evacuate in consideration of local characteristics and human conditions.

  In view of this, a system has been proposed in which information relating to disaster occurrence status and evacuation advice is individually notified to a user terminal registered in advance via a communication line. However, even if information about the occurrence of a disaster or evacuation advisories is notified, the user does not know how to act, and it is difficult for the user to recognize his / her danger and to act without urgency. Therefore, not all users who have received information will take evacuation action (see Non-Patent Document 1, for example).

  In general, it is said that human information processing characteristics in an emergency have the following characteristics. That is, first, humans have limited information processing resources, and information processing functions are limited. Regarding this characteristic, it is necessary to support causal interpretation of the situation and choice of options. It is a system that provides knowledge about useful scripts and causal schema. As a result, it is possible to support a decision maker who cannot make an appropriate judgment, or to provide a means for external response to a person who has caused a blocking reaction.

  Second, as described above, if the system cannot provide appropriate information to the system that provides knowledge, or if inappropriate information is entered, the system may make an incorrect decision. Need to be standardized in advance. However, in normal times, the usefulness of clue information that activates the script can be expected, but in many emergency situations, there is an element of surprise, so the situation is checked in addition to the clue by the script. It is necessary to pay attention to the means. Third, it relates to the general finding that people do not want to believe that the situation is dangerous (see, for example, Non-Patent Document 2).

  In order to disseminate information in an emergency in order to overcome the above-mentioned general tendency of people, it is necessary to devise a method for providing information. In other words, it is possible to determine what is necessary for the residents who have been evacuated and are provided with information to actually move to evacuation behavior based on the information processing characteristics of the person, and to provide information at a timely timing. is necessary.

  According to a series of experimental results on providing information to citizens, it is known that people tend to perceive objects as related to themselves when they perceive proximity in the meta. Therefore, it is important to give specific instructions to encourage people to take action, but that is not enough, and it makes information perceived as oneself, in other words, “not another person” Awareness is the key. It is important to clearly communicate that it is dangerous if you do not evacuate, not someone else.

  As described above, in a system that uniformly provides information on disasters to all people and a system that simply distributes information indicating the occurrence of disasters and evacuation advice to users individually, people are actually evacuated. It is generally difficult to move to action. Moreover, it is important not only to give specific instructions to people but also to recognize that it is not “other personnel”, and there is a strong demand for the construction of a specific system that takes this point into consideration.

  The present invention has been made paying attention to the above circumstances, and the purpose of this invention is to ensure that the user is surely informed of the increased possibility of a disaster, thereby causing the user to reliably perform the evacuation action. It is to provide a support system and its server device.

  In order to achieve the above object, the evacuation action support system and its server device according to the present invention can be connected via a communication network to a database for storing monitoring information of disaster monitoring target areas and user terminals used by users. In a simple evacuation action support server device, disaster-related information is collected from the monitoring information stored in the database via a communication network, and the current status of the disaster monitoring target area based on the collected disaster-related information Is the first stage for allowing the user to understand the situation, the second stage for allowing the user to recognize the possibility of a disaster, and the third stage for causing the user to take evacuation action. Based on the determination result, information corresponding to the stage of the current situation is selected from the collected disaster-related information, and a distribution message including the selected disaster-related information is generated to generate the distribution message. Is transmitted to the user terminal existing in the disaster monitoring target area via the communication network.

  Therefore, according to the present invention, the delivery message including the disaster related information indicating the situation of the disaster monitoring target area is delivered to the user terminal in three stages according to the increased possibility of the occurrence of the disaster. This makes it possible for users to recognize the situation that the disaster is not caused by other personnel, so that evacuation actions can be started faithfully without causing suspicion to the evacuation advisory, for example, when an evacuation advisory is suddenly notified. It becomes possible to make it.

  The monitoring information database may be provided with a disaster patrol result database for collecting and storing information representing disaster patrol results in addition to at least a weather information database for collecting and storing meteorological information. In this way, it is possible to collect not only basic monitoring information provided by existing monitoring organizations such as the Japan Meteorological Agency, but also local detailed monitoring information obtained by, for example, inspection of disaster prevention observers as disaster-related information It becomes.

The server device according to the present invention is also characterized by having the following various specific configurations.
The first configuration includes an area characteristic storage unit that divides the monitoring target area into a plurality of areas and stores the area characteristics related to the disaster for each area. Then, for each region, information corresponding to the region characteristic is selected from the collected disaster-related information based on the region characteristic stored in the region characteristic storage means, and the selected information is selected. Based on this, it is determined whether the current situation of the disaster monitoring target area is in the first, second or third stage.
With this configuration, it is possible to determine in which region the status of the disaster monitoring target area is in each region, and based on this determination result, the distribution message can be distributed to user terminals by region. Become.

In the second configuration, for each region, an important monitoring item unique to the region is set based on the region characteristic stored in the region characteristic storage means, and the disaster related information corresponding to the set important monitoring item is set as described above. Select from the collected disaster related information.
With this configuration, important monitoring items specific to each region are extracted for each region, and the current situation is judged based on disaster-related information corresponding to this important monitoring item. It is possible to judge the situation with high characteristics.

The third configuration is the first word or numerical value that suggests the possibility of a disaster from the collected disaster-related information, and the occurrence of a disaster, when judging the status of the disaster monitoring target area. The second word or numerical value and the third word or numerical value recommending evacuation are respectively searched. Then, when the first word or phrase is searched, the situation is shifted from the normal state to the first stage, and when the second phrase or numeral is searched, the situation is changed from the first stage to the first stage. In the second stage, when the third word or numerical value is searched, the above situation is shifted from the second stage to the third stage.
In this way, the situation can be determined by word matching processing or numerical value comparison processing.

In the fourth configuration, in addition to the first, second, and third words or values, a fourth word or value that instructs evacuation preparation is further searched from the collected disaster related information. And if the third word or number is detected, the current situation for general users is shifted from the second stage to the third stage, while the fourth word or number is searched. In this case, the current situation for users who need to prepare for evacuation is shifted from the second stage to the third stage.
In this way, the criteria for transition from the second stage to the third stage are based on evacuation for general users who do not interfere with the evacuation behavior and for elderly people and people with physical disabilities. Differentiate between users who need to be prepared for action.

The fifth configuration further includes a user characteristic storage unit that stores a user characteristic representing the difficulty level of the evacuation behavior for each user, and a distribution timing control unit. The delivery timing control means variably sets the delivery timing of the delivery message for each delivery target user based on the user characteristics stored in the user characteristics storage means.
If it does in this way, according to the characteristic showing the difficulty of a user's evacuation action, it will become possible to deliver a delivery message at the optimal timing for every user.

In the sixth configuration, when controlling the delivery timing, the first user group that needs to prepare for evacuation of the users to be delivered based on the user characteristics stored in the user characteristic storage means, and the first user group Into a second user group other than. And when transmitting the delivery message corresponding to a 3rd step, the transmission timing with respect to the user terminal which a 1st user group uses is based on the transmission timing to the user terminal which a 2nd user group uses. It is set to be before.
If it does in this way, it becomes possible to notify an evacuation recommendation to the 1st user group which needs evacuation preparation, and the 2nd other user group other than that at the optimal timing, respectively.

In the seventh configuration, when the delivery message corresponding to the third stage is generated, in addition to the disaster related information selected corresponding to the third stage, information indicating the evacuation place and arrival at the evacuation place Information indicating the route is included.
In this way, the user can acquire information indicating the evacuation site and information on the route to the evacuation site, in addition to the current situation, by the delivery message instructing the evacuation advisory. It becomes possible to do.

  In short, in the present invention, based on the collected disaster-related information, a first stage in which the current situation of the disaster monitoring target area allows the user to understand the situation, a second stage that allows the user to recognize the possibility of a disaster occurring. It is determined whether it is a stage or a third stage that causes the user to evacuate, and based on the determination result, a delivery message including disaster-related information is generated and transmitted to the user terminal. .

  Therefore, according to the present invention, there is provided an evacuation action support device capable of providing information that allows residents to recognize urgency effectively, and thereby reliably guiding residents who need to evacuate to evacuation actions. Can be provided.

And a management processing unit 5.

  The fluctuation information collection processing unit 1 includes a disaster related information collection function 11 and a disaster related information database 12. The disaster related information collection function 11 accesses the weather database DB1 and the road information database DB2 via the communication network NW, respectively, and acquires the latest weather information and road information related to the disaster. The acquired weather information and road information are stored in the disaster related information database 12. The disaster related information is composed of text data and image data.

  The disaster related information collection function 11 receives various instruction information related to the disaster transmitted from the disaster prevention management terminal BT via the communication network NW, and stores the received various instruction information in the disaster related information database 12. . The instruction information includes various alarms and instruction information for evacuation preparation and evacuation recommendation.

  The region-specific important item extraction processing unit 2 includes a residence database 21, a region characteristic database 22, and a past disaster database 23. Among these, the residence database 21 stores information representing the residence (address) of the user (resident) sent from the user terminals UT1 to UTm via the communication network NW. In the regional characteristic database 22, regional characteristic information indicating places where there is a risk of flood damage such as inundation, overflowing water, flooding, and bank breakage, debris flow, landslides, landslides, etc., by region Ea to En. Remembered. The past disaster database 23 stores disaster history information representing the past occurrence history of the flood and landslide disasters for each of the areas Ea to En.

  The important item / disaster-related information matching processing unit 3 includes an area-specific important information selection function 31 and an area-specific important information database 32. The regional important information selection function 31 creates a user list for each of the regions Ea to En based on the user's residence information stored in the residence database 21 and stores it in the region characteristic database 22. Based on the region characteristic information and the disaster history information stored in the past disaster database 23, important monitoring items specific to the region are extracted for each of the regions Ea to En. The user list and the important monitoring items are stored in the regional important information database 32.

  The region-specific important information selection function 31 selects the latest disaster-related information corresponding to the set important monitoring item from the disaster-related information stored in the disaster-related information database 12. Then, the disaster related information corresponding to the selected important monitoring item is stored in the regional important information database 32.

The distribution information selection processing unit 4 includes a time determination function 41 and a distribution purpose-specific information selection function 42. The time determination function 41 determines in which stage (STEP) the current state of the area is in each area Ea to En. This situation determination process is performed as follows.
That is, a request is made to the disaster related information database 12 and the latest disaster related information provided from the disaster related information database 12 is received. Then, it is determined by matching processing whether the latest disaster-related information received includes a word or phrase that suggests the occurrence of a disaster, and if it is included, the current situation is first understood by the user. (STEP 1). Further, when an alarm is included in the latest disaster-related information received, it is determined that the current situation is the second stage (STEP 2) for allowing the user to recognize the possibility of the occurrence of a disaster. Furthermore, when the latest disaster-related information received includes evacuation preparation or evacuation advisory, it is determined that the current situation is the third stage (STEP 3) for causing the user to evacuate.

  The distribution purpose-specific information selection function 42 receives the current situation determination result from the time determination function 41 for each of the areas Ea to En. Then, the received judgment result, that is, the disaster related information of the important monitoring item corresponding to the stage (STEP) is selected from the information stored in the regional important information database 32.

  The distribution timing management processing unit 5 includes a distribution timing control function 51, a distribution message selection function 52, a resident characteristic database 53, and a prescribed sentence database 54. The inhabitant characteristic database 53 stores inhabitant characteristic information representing the difficulty level of evacuation behavior for each user (inhabitant) existing in each area Ea to En. Resident characteristics information includes two types of characteristics, such as whether the user needs preparation for evacuation behavior, such as an elderly person or a physically handicapped person, or is a user who does not need preparation for other evacuation behavior. Is represented by The prescribed sentence database 54 stores prescribed sentences for each stage (STEP) necessary for generating a delivery message.

  The distribution timing control function 51 is a user who needs to prepare for evacuation based on the resident characteristics stored in the resident characteristic database 53 when transmitting a distribution message for notifying that the process has shifted to STEP 3. And a general user group, and the distribution message distribution timing is set for each of the classified user groups. Specifically, when transmitting a delivery message corresponding to STEP 3, if a word indicating “preparation for evacuation” is written in the disaster-related information database 12, a user group that needs to prepare for evacuation is selected, and this requirement is selected. The distribution message selection function 52 is instructed to transmit the distribution message to the preparation user group. On the other hand, when a word representing “evacuation advisory” is written in the disaster-related information database 12, a distribution message is selected so that a general user group is selected and the distribution message is transmitted to the general user group. The selection function 52 is instructed.

  The delivery message selection function 52 receives from the delivery timing control function 51 the delivery message type, the disaster related information included in the delivery message, and the delivery destination terminal address together with the delivery instruction. Then, a prescribed sentence corresponding to the type of the delivery message is read from the prescribed sentence database 54, and the delivery message is created by adding the disaster related information to the prescribed sentence. And this delivery message is transmitted to the user terminal of a delivery destination according to the said terminal address.

  Each database included in each of the processing units 1 to 5 described above is configured by a hard disk or a non-volatile semiconductor memory, and each processing function and control function is a central processing unit (CPU: Central Processing Unit). ).

Next, the operation of the evacuation action support server SV configured as described above will be described. FIG. 3 is a flowchart showing the main routine of the processing procedure and processing contents.
That is, in the evacuation action support server SV, first, the fluctuation information collection processing unit 1 operates to collect the fluctuation information in step 3a, and then the regional important item extraction processing unit 2 operates in step 3b to operate the region Ea. The important monitoring items are extracted for each of En. Also, in step 3c, the important item / disaster related information matching processing unit 3 operates, whereby the disaster related information corresponding to the important monitoring item is selected for each region Ea to En.

  Next, in step 3c, the distribution information selection processing unit 4 operates, and the current situation determination process and the disaster related information selection process corresponding to the determined stage (STEP) are performed for each of the regions Ea to En. Finally, in step 3d, the delivery timing management processing unit 5 operates to set delivery timing for each delivery target user according to the resident characteristics, and create and send a delivery message.

Hereafter, each said process is demonstrated in detail.
(1) Fluctuation information collection processing
FIG. 4 is a flowchart showing a subroutine for collecting the fluctuation information and processing contents.
The fluctuation information collection processing unit 1 monitors the collection timing at step 4a. In this state, when the collection timing set in advance is reached, the weather information database DB1 and the road information database DB2 are respectively accessed via the communication network NW in step 4b, and updated latest weather information related to the disaster is obtained in step 4c. And road information. Then, the acquired latest weather information and road information are stored in the disaster related information database 12 in step 4d. The weather information and road information may be acquired in response to arrival of an update notification from the weather information database DB1 and the road information database DB2 in addition to accessing from the fluctuation information collection processing unit 1.

  As a result, the disaster-related information database 12 includes not only general weather forecasts, road conditions, and transportation operation conditions, but also occurrences of disasters such as precipitation, river level, and wind speed by region Ea to En. The latest information related to is stored sequentially. Note that a disaster-related message input by the disaster prevention instructor in the server SV is also stored in the disaster-related information database 12.

  In addition, the fluctuation information collection processing unit 1 also receives these instruction information via the communication network NW even when various instruction information related to the disaster is transmitted from the disaster prevention management terminal BT installed in the disaster countermeasure headquarters. To do. The received various instruction information is stored in the disaster related information database 12.

(2) Extraction processing of important items by region and matching processing of important items and disaster-related information
FIG. 5 is a flowchart showing a subroutine of the processing procedure and processing contents.
The regional important information selection function 31 creates a user list for each of the regions Ea to En based on the user's residence information stored in the residence database 21 as advance preparation. Next, in step 5a, information representing the regional characteristics is read from the regional characteristic database 22 for each region where the user resides. At the same time, information representing disasters that have occurred in the past in each region is read from the past disaster database 23. In step 5b, based on the read area characteristics and information representing past disasters, important monitoring items specific to the area are extracted for each area.

  For example, if there is a risk of debris flow, the total rainfall data is extracted, and if the river is inundated, river level data and hourly precipitation data are extracted. Then, the extracted important monitoring items are stored in the regional important information database 32 in step 5c.

Next, the region-specific important information selection function 31 sends a request to the disaster-related information database 12 in step 5d, and whether or not the disaster-related information has been updated based on the information provided in response to this request in step 5e. judge. If the disaster-related information is updated, the process proceeds to step 5f, and the information corresponding to the important monitoring item for each region is selected from the updated disaster-related information, and the selected disaster-related information is selected. In step 5g, the region-specific important information database 32 is stored.
As a result, the disaster-related information is stored in the regional important information database 32 every time the disaster-related information corresponding to the important monitoring item among the disaster-related information stored in the disaster-related information database 12 is updated. Are classified and stored sequentially for each .about.En.

(3) Situation judgment processing and distribution information selection processing
FIG. 6 is a flowchart showing a subroutine of the processing procedure and processing contents.
In step 6 a, the distribution information selection processing unit 4 makes a request to the disaster related information database 12 and receives the latest disaster related information provided from the disaster related information database 12. Then, in step 6b, it is determined whether or not the latest disaster-related information received includes a word or phrase that suggests the occurrence of a disaster. Is determined as the first stage (STEP 1) for allowing the user to understand the situation. Then, in step 6d, the disaster related information corresponding to STEP1 of the determination result is selected from the regional important information database 32.

  For example, when a word or phrase that suggests the occurrence of a disaster such as “typhoon” or “heavy rain” is found from the latest disaster-related information, or the precipitation exceeds a preset first threshold, the current situation is changed to STEP1. Judge. Then, as the disaster related information corresponding to STEP 1, for example, as shown in FIG. 8, the current weather forecast, road information, and transportation operation information are selected from the regional important information database 32.

  On the other hand, it is assumed that “alarm” is found from the latest disaster-related information in step 6e, or that it is detected in step 6f that the water level of the river or the precipitation in the upstream area exceeds a preset first threshold value. In this case, the distribution information selection processing unit 4 determines that the current situation is STEP2 at step 6g. Then, in step 6h, as disaster related information corresponding to STEP 2, as shown in FIG. 8, for example, in addition to global information such as current weather forecast, road information and transportation operation information alarm, the contents of the alarm, the corresponding area Local information such as rainfall and river water level is selected from the regional important information database 32.

  In Step 6i, “preparation for evacuation” is found from the latest disaster-related information, or the river level or precipitation in the upstream reaches the second threshold set higher than the first threshold. Is detected. In this case, the distribution information selection processing unit 4 determines in STEP 6j that the current situation is STEP3 for causing the user group that needs to prepare for evacuation to evacuate. In step 6k, as disaster-related information corresponding to STEP 3, in addition to global information such as current weather forecasts, road information, and transportation operation information alarms as shown in FIG. From the regional important information database 32, local information unique to the region such as the rainfall of the region and river water level, and information for supporting the evacuation behavior such as the evacuation location and the evacuation situation of neighboring residents are selected.

  Furthermore, in step 6l, it is detected that “evacuation advisory” is found from the latest disaster-related information, or that the water level of the river or the precipitation in the upstream reaches a warning value set higher than the second threshold value. To do. In this case, the distribution information selection processing unit 4 determines in STEP 6m that the current situation is STEP3 for causing the general user group in the corresponding area to perform evacuation behavior. In step 6n, as disaster-related information corresponding to STEP 3, for example, as shown in FIG. 8, in addition to global information such as current weather forecasts, road information, and transportation operation information alarms, the contents of evacuation recommendation, relevant From the regional important information database 32, local information unique to the region such as the rainfall of the region and river water level, and information for supporting the evacuation behavior such as the evacuation location and the evacuation situation of neighboring residents are selected.

  That is, as shown in FIG. 8, in STEP1, global disaster related information is selected as distribution information, and when moving to STEP2 and STEP3, in addition to global information, local disaster related information in the corresponding area is selected. In addition, for users who can evacuate on their own, such as elderly people, but who need time to start evacuation, that is, users who need to prepare for evacuation, they are more likely than general users such as healthy people. Transition from STEP2 to STEP3 at an early timing.

(4) Delivery timing control and delivery message creation processing
FIG. 7 is a flowchart showing a subroutine of the control procedure and control contents.
The distribution timing management processing unit 5 issues a request to the disaster-related information database 12 in step 7a, and the disaster-related information provided from the disaster-related information database 12 in response to this request is updated to information that triggers a change in STEP. Monitor whether it was done. In this state, it is assumed that words and phrases indicating the possibility of a disaster such as “typhoon” and instruction information such as warning, evacuation preparation, and evacuation recommendation are detected from the disaster-related information.

  Then, the distribution timing management processing unit 5 first reads out the resident characteristics in the resident characteristic database 53 in step 7b, and based on the resident characteristics, in step 7c, the users in the distribution target area are prepared as a preparation user group and a general user group. And categorized as Next, when a word suggesting the possibility of a disaster such as “typhoon” for shifting the normal state from the disaster related information to STEP 1 is detected, it is necessary to use it in Step 7d and Step 7e, respectively. The same distribution timing is set for the user group and the general user group. In addition, even when “alarm”, which is a phrase for shifting STEP2 to STEP3, is detected from the disaster-related information, the same distribution is made to the preparation-required user group and the general user group by Step 7d and Step 7e. Set the timing.

  On the other hand, when “preparation for evacuation”, which is a word for shifting STEP2 to STEP3 for the users who need to be prepared, is detected from the disaster related information, the group of users who need to be prepared in step 7d. Set the delivery timing. If “evacuation advisory”, which is a phrase for moving STEP2 to STEP3 for general users, is detected from the disaster-related information, the distribution timing is set for the general users in step 7e. To do.

  In addition, the delivery timing management processing unit 5 selectively reads out the prescribed sentence corresponding to the STEP representing the current situation from the prescribed sentence database 54 in step 7f. In step 7g, the delivery message is edited by adding disaster-related information corresponding to the STEP selected in the delivery information selection process (4) to the above-mentioned read-out prescription. Then, the edited delivery message is transmitted by electronic mail to the delivery destination user terminals UT1 to UTm in step 7h according to the address of the selected user group.

  For example, when the current situation changes from the normal state to STEP 1, a delivery message in which the current weather overview and forecast are added to the prescription sentence for notifying the approach of the typhoon as shown in FIG. 9 is edited. The delivery message is broadcast to all user terminals regardless of the area.

  In addition, when the current situation shifts from STEP 1 to STEP 2 in response to the flood warning, for example, as shown in FIG. A distribution message to which disaster-related information or the like for each En is added is edited. This distribution message is broadcast to all the user terminals for each of the areas Ea to En.

  In addition, when the current situation has shifted from STEP 2 to STEP 3 in response to the evacuation preparations, the provisions for making the users who need to start evacuation preparations include the contents of evacuation preparations and disasters by region Ea to En. The delivery message with the related information added is edited. And this delivery message is selectively transmitted toward the terminal of a preparation required user according to area Ea-En.

  On the other hand, when the current situation shifts from STEP 2 to STEP 3 in response to the issuance of an evacuation advisory, for example, as shown in FIG. A distribution message to which disaster-related information for each region Ea to En, information indicating an evacuation place, an evacuation route, and the like is added is edited. And this delivery message is transmitted toward a general user's terminal according to area Ea-En. The delivery message accompanying this evacuation advisory may be transmitted not only to a general user's terminal but also to a user terminal requiring preparation.

  In addition, if the relevant disaster-related information is updated after the delivery message accompanying the evacuation advisory is sent, a delivery message that supports evacuation behavior is created at that time and additionally sent to the target user's terminal Is done. For example, as shown in FIG. 12, a delivery message in which information indicating an evacuation situation is added to a prescribed sentence for supporting the evacuation behavior of a user is edited. The delivery message that supports this evacuation action is edited each time the disaster-related information is updated, for example, when the river water level changes further or when new information is input by the disaster prevention instructor of this evacuation action support system. It is corrected and additionally transmitted to the user terminal to be distributed.

  As described above, in the first embodiment, the fluctuation information collection processing unit 1 collects new information related to the occurrence of a disaster from the weather information database DB1, the road information database DB2, and the disaster prevention management terminal BT, and thus relates to the disaster. Store in the information data table 12. Then, the region-specific important item extraction processing unit 2 extracts important monitoring items for each of the regions Ea to En, selects disaster-related information corresponding to the extracted important monitoring items from the disaster-related information data table 12, and selects the region. It is stored in another important information database 32. In addition, in the distribution information selection processing unit 4, the current situation for each of the regions Ea to En is STEP1 for allowing the user to understand the situation, STEP2 for allowing the user to recognize the possibility of a disaster, and for the user to evacuate. It is determined which of the STEPs 3 causes the disaster, and disaster related information corresponding to the determined STEP is selected from the region-specific important information database 32. Finally, the distribution timing management processing unit 5 sets the distribution timing for each distribution target user according to the resident characteristics, edits the distribution message corresponding to the determined STEP, and sets the distribution target user terminal. I am trying to send it.

  Therefore, the current status is notified to the user terminal in three stages according to the increased possibility of disaster occurrence. This makes it possible for the user to recognize the situation that the disaster is not another person's affairs, so that the evacuation behavior can be faithfully observed without causing any doubt about the evacuation recommendation, for example, when the evacuation recommendation is suddenly notified. Can be started.

  In addition, the above three-step notification operation is performed separately for each of the areas Ea to En. For this reason, it becomes possible to perform a user's evacuation action support for every area. In addition, for each of the regions Ea to En, important region-specific monitoring items are extracted based on the region characteristics and past disaster occurrence histories, and the current situation is judged based on the disaster-related information corresponding to these important monitoring items. Therefore, it is possible to make a highly effective situation determination for each of the areas Ea to En in consideration of the regional characteristics.

In addition, users can self-evacuate like elderly people, but it is possible to start immediate evacuation with a group of users who take time to start evacuation (a group of users who need to prepare for evacuation). When a transition is made from STEP2 to STEP3 when an evacuation preparation is issued, a delivery message is transmitted to the required users group, and when a transition from STEP2 to STEP3 is issued when an evacuation recommendation is issued A delivery message is sent to a general user group. Therefore, evacuation preparation instructions can be given to users who need to be prepared for evacuation behavior, such as elderly people and people with physical disabilities, earlier than general users. It is possible to start evacuation smoothly without inconvenience to a handicapped person. In addition, since the information on the evacuation place and the evacuation route is added to the delivery message transmitted when moving to STEP 3, the user can evacuate smoothly and safely based on the information.
