Description

  The present invention relates to an information distribution technique, and more particularly to an evacuation information distribution technique that simultaneously distributes various types of evacuation information related to evacuation during a disaster to previously registered terminal devices.

  If there is a possibility of a disaster, the government will inform the residents about the use of public relations vehicles, if it is widespread, or other necessary television broadcasts, radio broadcasts, verbal transmissions, sirens, and evacuation recommendations and instructions Is transmitted. In such evacuation advisories and evacuation instructions, it is important to clarify routes to evacuation destinations and shelters, in addition to advisors and reasons for evacuation.

  On the other hand, along with the popularization of mobile phone services, a technology has been proposed that guides route information to people who move to an evacuation destination in the event of a disaster using such communication services. For example, the mobile terminal periodically requests the route search server to search for a route related to the evacuation route between desired points, and the obtained evacuation route is stored in the storage unit, and the evacuation route of the storage unit is stored in the case of a disaster. There is a technique for displaying (see, for example, Patent Document 1).

  However, such a conventional technique is premised on the principle of human behavior such that evacuation behavior occurs uniformly. For this reason, the difference in evacuation decision-making criteria in terms of risk awareness, that is, the difference in crisis awareness, is not taken into account, and the importance and necessity of evacuation cannot be informed specifically to residents with low crisis awareness There was a problem.

  Evacuation information provided by government agencies in the event of a disaster, etc., is not information that corresponds to individual refugees or specific areas, but only information that is publicized to a wide range of local residents, and is specific to one individual. The distribution information is not. For this reason, even if the current evacuation information is communicated, evacuees with high risk awareness take the initiative based on the information, etc., but evacuees with low risk awareness, etc. There is a delay in escape due to the fact that the degree cannot be properly recognized, or because the situation does not know how to act. This is more prominent in disaster types that require a certain amount of time to feel direct dangers, such as floods, earth and sand disasters, and storm surge disasters, rather than disaster types that can feel direct dangers such as earthquakes.

During actual disasters, individuals (evacuation behavior psychology) such as evacuees who take the initiative to evacuate due to differences in risk perception, and evacuees who cause evacuation after confirming the evacuation behavior of someone else Difference in evacuation decision-making criteria occurs.
Therefore, evacuation information that is different from those who evacuate on their own initiative, that is, those who are evacuated on their own initiative, that is, vulnerable people who have a low risk awareness and who are psychologically uneasy, are able to obtain a sense of security and smoothly evacuate. It is necessary to provide evacuation information that can be started. This is because the information content that supports evacuation differs depending on the evacuation decision-making criteria, and it can be said that this is a natural approach from the perspective of social psychology. The definition of the difference in evacuation decision-making criteria captures the potential psychology at the time of a disaster. It can be said that it is a natural behavior principle.

  This invention is for solving such a subject, and it aims at providing the evacuation information which can notify concretely the importance and necessity of evacuation to the inhabitant with low crisis consciousness. .

In order to achieve such an object, an evacuation information distribution apparatus according to the present invention is an evacuation information distribution apparatus that distributes evacuation information related to evacuation during a disaster to communication terminals of a plurality of evacuees via a communication network. The communication terminal is an active refugee terminal carried by an active refugee who carries an active evacuation action equivalent to an opinion leader in innovator theory , or a passive evacuation action equivalent to an early majority or late majority in innovator theory. It is classified into one of the passive evacuees terminals used by the passive evacuees to be taken, and the terminal database registered in advance together with each communication address, and the active that is classified in the terminal database among the communication terminals at the time of evacuation Location information acquisition that acquires location information indicating the location of the active refugee terminal from the evacuee terminal via the communication network. Evacuation status information generation unit for generating evacuation status information indicating the evacuation status of active evacuees based on the location information acquired by the location information acquisition unit, and passive evacuation classified by terminal database among communication terminals And an information distribution unit that distributes the evacuation status information generated by the evacuation status information generation unit to the person terminal.

  At this time, the position of the active refugee terminal is determined based on the position information acquired in time series by the position information acquisition unit or the position information indicating the time series change of the position of the active refugee terminal. You may make it produce | generate the evacuation condition information containing a series change.

  Moreover, you may use the map image which plotted the locus | trajectory which shows the time-sequential change of the position of an active refugee terminal as evacuation status information on a map.

  Further, the position information acquisition unit sequentially acquires new position information from the active refugee terminal, and the information distribution unit converts the evacuation situation information generated from the new position information by the evacuation situation information generation part to the passive refugee terminal. May be delivered sequentially.

  The information distribution unit may stop the acquisition of the position information and the distribution of the evacuation status information after a predetermined distribution period has elapsed since the start of the acquisition of the position information or the distribution of the evacuation status information.

  Further, the program according to the present embodiment is a program for causing a computer to function as each unit constituting the evacuation information distribution apparatus described above.

According to the present invention, in the evacuation situation information, when it can be confirmed that the active refugee is evacuating very quickly, the active refugee recognizes that the risk of disaster is high, When it can be confirmed that the active refugee has evacuated without rushing, the active refugee recognizes that the risk of disaster is low. That is, the evacuation status information includes the risk recognition level of active refugees.
Therefore, by delivering such evacuation status of active evacuees to passive evacuees, passive evacuees who want to evacuate for the first time after confirming someone's evacuation behavior, that is, residents with low risk awareness, Can inform the importance and necessity of evacuation specifically. For this reason, the evacuation behavior of the passive refugees can be strongly urged, the evacuation behavior can be started smoothly, and the evacuation rate of the entire residents can be improved.

[Evacuation information distribution device]
First, the evacuation information distribution apparatus according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing the configuration of the evacuation information distribution apparatus according to this embodiment.

  The evacuation information distribution device 10 is composed of a communication processing device such as a server device as a whole, and evacuation information related to evacuation at the time of a disaster such as when a disaster occurs or when there is a risk of a disaster is transmitted to a mobile phone network or the Internet. A function of delivering to a plurality of evacuees' communication terminals such as an active evacuee terminal 21 carried by the active evacuees 20 and passive evacuee terminals 31 and 32 used by the passive evacuees 30 via the communication network 40 Have.

  Among these, the active refugee terminal 21 is composed of a mobile communication terminal such as a mobile phone or a PDA carried by the active refugee 20. The passive evacuee terminal 31 is composed of a mobile communication terminal such as a mobile phone or PDA carried by the passive evacuee 30, and the passive evacuee terminal 32 is a fixed communication terminal such as a personal computer used indoors by the passive evacuee 30. Consists of.

The administrator terminal 50 includes an information processing terminal such as a personal computer or a portable terminal, and has a function of connecting to the evacuation information distribution apparatus 10 via a communication line and remotely controlling evacuation information distribution control.
A geographic information system (GIS) 51 includes a communication processing device such as a server device, is connected to the evacuation information distribution device 10 via a communication line, and maps in response to a request from the evacuation information distribution device 10. The system has a function to provide information and the acquired location information so that, for example, a logical contradiction such as a line of action trajectory running on the building due to a position error caused at the time of positioning does not occur. It has a function of generating new map information by plotting on a map while performing necessary position correction using existing road information and building information. The geographic information system 51 can be widely used as an image technology related to disaster prevention. For example, the spatial information (attribute information) of each element is added and used in a disaster or the like. In addition, about the specific example of a geographic information system, what is necessary is just to utilize the existing technique (for example, refer nonpatent literature 1 etc.).

[Principle of the Invention]
First, the principle of the present invention will be described.
As mentioned above, not all evacuees who evacuate based on evacuation information related to evacuation, such as evacuation destination and evacuation time provided by government agencies at the time of disaster, have the same risk awareness. Differences are recognized.
For this reason, even if the current evacuation information is communicated, evacuees with high risk awareness take the initiative based on the information, etc., but evacuees with low risk awareness, etc. There is a delay in escape due to the fact that the degree cannot be properly recognized, or because the situation does not know how to act.

During actual disasters, individuals (evacuation behavior psychology) such as evacuees who take the initiative to evacuate due to differences in risk perception, and evacuees who cause evacuation after confirming the evacuation behavior of someone else Difference in evacuation decision-making criteria occurs.
Therefore, evacuation information that is different from those who evacuate on their own initiative, that is, those who are evacuated on their own initiative, that is, vulnerable people who have a low risk awareness and who are psychologically uneasy, are able to obtain a sense of security and smoothly evacuate. It is necessary to provide evacuation information that can be started.

  The inventors conducted a questionnaire survey based on the theory of social psychology in order to confirm the existence of such a difference in evacuation decision-making criteria, that is, a difference in crisis consciousness, in the degree of risk recognition. Analyzed, subjects were classified into several groups according to differences in evacuee behavior. In addition, Leon Festinger's social behavior is shared by the evacuation behavior model obtained from these groups and the consumer behavior model in Everett M. Rogers's innovator theory. Based on the comparative process theory, we analyzed the importance of evacuation information in the evacuation behavior model, that is, the propagation of danger to disasters.

[Innovator theory]
FIG. 2 is an explanatory diagram showing consumer types of innovator theory.
First, I will explain innovator theory and its consumer type. According to innovator theory, consumers' attitudes toward product purchases are listed in order of early purchase of new products: innovators (innovators), opinion leaders (early adopters), early majorities (early majors). ), Late Majority (Late Majority), and Laggards (Laggards).

  Of these, innovators are adventurous and willing to adopt new ones, accounting for 2.5% of the total market. An opinion leader is a person who is sensitive to fashion and who collects information and makes decisions. It has great influence on other consumers and is also called Early Adopters, accounting for 13.5% of the total market. Early Majority is a relatively prudent person who takes in new things faster than average, accounting for 34.0% of the total market. Late Majority is a relatively skeptical person who makes the same choice after seeing what the majority of others are trying, accounting for 34.0% of the total market. Lagard is one of the most conservative people who have little interest in trends and trends and do not adopt until innovation becomes a tradition, accounting for 16.0% of the total market.

  Among these consumer types, innovators have a small number of people, and the focus is on the novelty of the product itself, and it does not pay much attention to the value of the product. Opinion leaders, on the other hand, pay attention to new values and have a great influence on other consumers, so they play the role of conveying new values through their networks. Even if innovators and opinion leaders are combined, their cumulative share is only 16% of the total market. However, this 16% corresponds to a region where the cumulative frequency distribution curve grows rapidly, and it is considered that whether or not it spreads to these two will be the turning point of whether it will spread to the next early majority or late majority. . Innovator theory advocates this point of consideration as "the logic of 16% penetration".

[Questionnaire survey]
Next, a questionnaire survey will be described. In the questionnaire survey, questions on evacuation behavior and daily behavior were prepared using 44 participants from an evacuation drill conducted in a certain area as subjects. FIG. 3 is an example of a questionnaire question. The answering method is a format in which one of “I do not think so”, “I do not think so”, “I think so”, or “I think so” is selected.
Using the scores for evacuation behavior and daily behavior calculated for each subject from these answers, the subjects were classified into several clusters according to differences in refugee behavior. At this time, the difference in the degree of risk recognition was scored by weighting the questioning factors that measure qualities as opinion leaders in the consumer category.

FIG. 4 shows a clustering analysis result regarding evacuation behavior. Here, the horizontal axis is a score related to evacuation behavior, and the vertical axis is a score related to daily behavior. It can be considered that the higher the score, the more active behavior is taken, and the smaller the score, the more passive behavior is taken.
According to this clustering analysis result, it was found that subjects were roughly classified into six groups from Group A to Group F, depending on the combination of behavioral characteristics in evacuation behavior and behavioral characteristics in daily behavior. Moreover, about the F group, it turned out that the five small classifications from F1 group to F5 group exist.

  FIG. 5 is a psychological analysis result for each refugee action classification. Here, for each refugee behavior classification obtained in FIG. 4, the correspondence between the psychological analysis of the subject belonging to the classification and the consumer type in the innovator theory, and the gender configuration of the subject belonging to the classification are shown. Has been.

  Of these, Group A is active in daily regional exchanges, and has a strong tendency to desire a leader position in the town. In the event of a disaster, he collects various information himself while paying attention to the situation of evacuation in the neighborhood, and evacuates on his own initiative. In addition, there is a strong tendency to call attention and action instructions to neighbors based on the information, and a cause to try to evaluate oneself (type that can play a role of local leadership). Therefore, the group A corresponds to an opinion leader in the innovator theory.

  Group B is slightly less inclined to take a leadership position in town, but is actively engaged in local exchange. There is also a strong tendency to collect various information by themselves without worrying about the evacuation in the neighborhood at the time of a disaster, and to call attention and action instructions to the neighbors based on the information, and the cause to evaluate themselves ( Various types of information gathering activities before active evacuation advisories are issued). Accordingly, group B is a so-called leading consumer and corresponds to an opinion leader.

  In Group C, local exchanges are limited to exchanges with close acquaintances, and there is a tendency for local activities and connections with neighbors to be somewhat weak. However, in the event of a disaster, there is a strong tendency to collect various information by themselves, and to call attention and action instructions to neighbors based on that information, as well as a cause to evaluate themselves (actively evacuation advisories are issued) Various types of information gathering activities before.) Therefore, the group C is a so-called leading consumer reserve army and corresponds to an early majority (see, for example, Non-Patent Document 2).

  Group D has little tendency to desire a leadership position in the town, but regional exchanges are relatively active. In the event of a disaster, we collect various information on our own without worrying about the state of evacuation in the neighborhood, and take the initiative to evacuate based on that information, but the tendency to call attention to neighbors is somewhat low (self-contained type) . Therefore, the D group corresponds to an innovator in the innovator theory.

  Group E is very active in daily regional exchanges, and has a strong tendency to desire a leader in the town. However, in the event of a disaster, you can evacuate after confirming the evacuation behavior of someone and the surrounding evacuation, and there is a tendency to speak to other neighbors as well as the reason for evaluating yourself (actively) Various types of information gathering activities are not conducted before the evacuation advisory is issued). Therefore, the E group is a market avenue that plays a hub role in information transmission, and corresponds to an early majority.

  In the F1 group, regional exchanges are limited to exchanges with close acquaintances, and there is a tendency for local activities and connections with neighbors to be somewhat weak. In the event of a disaster, he collects various information and confirms someone's evacuation behavior, but he does not take the initiative. However, when evacuating, there is a tendency to talk to neighbors and a reason to evaluate themselves (a cautious type that does not take the initiative). Therefore, the F1 group corresponds to the early majority in the innovator theory.

  In the F2 group, regional exchanges are limited to exchanges with close acquaintances, and there is a slight tendency to see some local activities and connections with neighbors. In the event of a disaster, there will be no information gathering activity or confirmation of someone's evacuation behavior, nor will they take the initiative in evacuating. However, when evacuating, there is a tendency to speak to neighbors and a cause to evaluate themselves (passive introversion type). Therefore, the F2 group corresponds to the late majority in the innovator theory.

  In the F3 group, regional exchanges are limited to exchanges with close acquaintances, and there is a tendency for local activities and connections with neighbors to be somewhat weak. There is interest and interest in people's opinions, but I do not consult myself. In the event of a disaster, there is also a tendency to evacuate at their own discretion by collecting various information and checking someone's evacuation behavior. However, when she evacuates, she also speaks to neighbors, but the sense of accomplishment tends to be somewhat low. Accordingly, the F3 group corresponds to the early majority in the innovator theory.

  In the F4 group, local exchanges are limited to exchanges with close acquaintances, and there is a tendency for local activities and connections with neighbors to be somewhat weak. There is interest and interest in people's opinions, but I do not consult myself. At the time of a disaster, there are two trends: information gathering activities and the tendency to confirm someone's evacuation behavior, and the opposite tendency. Both tend to evacuate at their own discretion. In addition, when evacuating, there is a mix of people who tend to talk to neighbors but who do not feel a sense of accomplishment at all. Therefore, the F4 group has characteristics of both early majority and late majority in the innovator theory.

  In the F5 group, local exchanges are limited to exchanges with close acquaintances, and there is a tendency for local activities and connections with neighbors to be weak. There is interest and interest in people's opinions, but I do not consult myself. In the event of a disaster, only someone's evacuation behavior is confirmed, no information gathering activities are performed, and there is a low tendency to evacuate at their own discretion. Also, when evacuating, there is a tendency to speak to neighbors, but there is a tendency to feel no achievement at all. Therefore, the F5 group has both the properties of late majority and lagard in the innovator theory.

[Contrast between evacuation behavior and consumer behavior]
FIG. 6 is a comparison table of evacuee behavior classification and consumer type of innovator theory. FIG. 7 is a graph comparing the behavior of evacuees and the consumer type of innovator theory.
The composition ratios are calculated by applying the refugee behavior classification obtained by the clustering analysis result, that is, each of Group A to Group E and Group F1 to Group F5 to the consumer type of innovator theory. In addition, among the subjects, those who experienced disaster were included, so for each consumer type, the ratio by classification indicating the proportion of disaster experienced people among subjects of the consumer type, The ratio of the total number of experienced persons showing the proportion of the disaster experienced persons is shown.

  As shown in FIG. 6, among the refugee behavior classifications, the composition ratio of the classification belonging to the innovator is 3.0%, the composition ratio of the classification belonging to the opinion leader is 17.7%, and the composition ratio of the classification belonging to the early majority is The composition ratio of the classification belonging to the late majority was 17.6, and the composition ratio of the classification belonging to Lagard was 8.8%. As shown in FIG. 7, the frequency distribution curve P1 of these composition ratios has a larger early majority composition ratio and a smaller late majority composition ratio than the composition ratio frequency distribution curve P0 related to the consumer type. It turns out that it has the same distribution tendency as the consumer type.

  As a result, the innovator theory consumer behavior model, in which information about new products propagates to many consumers via each consumer group classified as a consumer category, It can be seen that the evacuation behavior models have similarities. Therefore, it can be understood that when the information related to the new product is replaced with the evacuation information, the evacuation information propagates to many refugees via each refugee group obtained by the evacuation behavior model classification.

Here, in the event of a disaster, the evacuation decision criteria differ for each evacuee according to the above-mentioned difference in the degree of crisis awareness with respect to the disaster. The evacuees who have the cause to try to evacuate for the first time are separated.
This means that the opinion leaders in the innovator theory take the active action of actively discovering the value of new products, whereas the early majority and late majority receive the value of new products passively. It is very similar to the consumer behavior model of taking action.

[Propagation of importance of evacuation]
In the consumer behavior model in innovator theory, it is pointed out that many of the early and late majority are provided with the value of new products by opinion leaders, and that the sales leaders hold the key to expanding sales of new products. Yes. In other words, when the opinion leader grasps the value of the new product and distributes the new information to the early majority and late majority, the value of the new product is widely communicated.

On the other hand, in the evacuation behavior model, as described above, an evacuee who takes the initiative in evacuation, that is, an active refugee corresponds to an opinion leader, and an evacuation in which an evacuation cause occurs only after confirming someone's evacuation behavior. An evacuee, that is, a passive refugee, corresponds to an early majority or a late majority.
Therefore, for evacuation information related to disasters, it is important that active refugees distribute new information indicating the results of grasping evacuation information to passive refugees. It is thought to lead to communication.

  For this reason, if the active refugee acquires the result of grasping the evacuation information and distributes it to the passive refugees who are less conscious of the crisis, the importance and necessity of evacuation can be specifically notified. In addition, this makes it possible to strongly encourage the evacuation behavior of passive refugees, to start the evacuation behavior smoothly, and to improve the evacuation rate of the entire residents.

  The present invention pays attention to such points, and in the evacuation information distribution device 10 that distributes evacuation information related to evacuation during a disaster to communication terminals of a plurality of evacuees via the communication network 40, the communication terminal is active. The active refugee terminal 21 carried by the active refugee 20 who performs the evacuation action or the passive refugee terminals 31 and 32 used by the passive refugee person 30 which performs the passive evacuation action. It is registered in the terminal database together with the communication address, and indicates the position of the active refugee terminal 21 via the communication network 40 from the active refugee terminal 21 classified in the terminal database among the communication terminals at the time of evacuation. Passive evacuation that acquires location information, generates evacuation status information indicating the evacuation status of the active refugee 20 based on the location information, and is classified by the terminal database among the communication terminals To the terminal 31 and 32 is the generated evacuation status information that was set to deliver.
