Description

  The present invention relates to a tsunami countermeasure system. More specifically, the present invention relates to a tsunami countermeasure system that allows residents to independently conduct research on evacuation routes in the event of a tsunami caused by an earthquake.

  When an earthquake occurs, not only can houses be destroyed directly due to seismic forces, but tsunamis can occur in coastal areas. When such a tsunami occurs, a house may be swept away or a road may be flooded, and evacuation may occur.

  In addition, when a tsunami occurs, a normal evacuation route may be submerged, and the evacuation route may not be able to pass. In other words, if there is no tsunami, even if there is a possibility of being able to evacuate, there is a possibility that it will be impossible to evacuate and will die.

  Especially for people with physical disabilities and elderly people, not only will they need to evacuate in a shorter time and the shortest route, but will also require the cooperation of neighboring residents for evacuation. . However, when a tsunami occurs, there is a high possibility that the evacuation route and evacuation cooperation assumed for disasters such as ordinary earthquakes will not work effectively.

  As described above, in areas where damage may occur due to tsunamis, residents are trained to identify and evacuate evacuation routes and evacuation cooperation systems that allow safe evacuation even in the event of a tsunami. There is a need.

  Here, when examining evacuation routes and evacuation cooperation systems, it is necessary to understand how flooding and damage spread when a tsunami occurs. And the technique which simulates flood damages, such as a tsunami, is developed conventionally (refer patent document 1).

  On the other hand, a technique for simulating an evacuation route for evacuating a person safely in the event of a fire or a flood has been developed (Patent Document 2, etc.). Patent Document 2 discloses an evacuation guidance system that detects an environmental state such as a water level, smoke concentration, or temperature and guides it to an appropriate evacuation route. In Patent Document 2, a safe evacuation route can be specified based on simulation data such as how water enters a structure such as an underground mall, how smoke flows, how a fire spreads, and so on. Discloses a technique that can visually indicate the direction of an evacuation route.

  By the way, the software etc. which simulate the flood damage like patent document 1 mentioned above simulate the occurrence condition of flood damage, and do not have the function to construct a safe evacuation route. Therefore, the evacuation route and evacuation cooperation system must be examined separately based on the simulation results. For example, if we ask a specialist in disaster prevention measures, we believe that it is possible to build an evacuation route and evacuation cooperation system based on the simulation results. However, it is rare for specialists to fully grasp the actual situation at the site, and it is difficult to establish an appropriate evacuation route and evacuation cooperation system. On the other hand, it is difficult for residents to build their own evacuation routes and evacuation cooperation systems based on the simulation results. In other words, it is very difficult to establish an evacuation route and evacuation cooperation system suitable for the local situation even if the situation of the occurrence of flood damage is obtained by software that simulates flood damage.

  On the other hand, with the technique of Patent Document 2, it is possible to simulate an evacuation route during a fire or flood. However, the technique of Patent Document 2 is merely a method for calculating an evacuation route in a space that is closed to some extent, such as a building or an underground mall, and the evacuation route is limited. And since the technique of patent document 2 is not what calculates the evacuation route in the situation where there are an infinite number of evacuation routes which can be assumed like the outdoors, it simulates the evacuation route in case of flood damage. That is virtually impossible.

  As described above, at present, there is no simulation software or the like suitable for building an evacuation route when a tsunami caused by an earthquake occurs.

  And in constructing appropriate evacuation routes and evacuation cooperation systems in tsunamis, it is important to incorporate the opinions of residents who have a good grasp of the actual situation at the site. If the evacuation route and the evacuation cooperation system can be constructed in a form in which the resident participates, the resident can understand the importance of grasping the appropriate evacuation route and the importance of the construction of the evacuation cooperation system. Then, in the event of an actual tsunami, it can be expected that a synergistic effect will be created that makes it easier for individual residents to take appropriate measures.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a tsunami countermeasure system in which residents can participate in the construction of an evacuation route in the event of a tsunami, and can also educate the importance of disaster countermeasures to the residents. .

The tsunami countermeasure system of the first invention is a tsunami countermeasure system that is used by residents to voluntarily investigate and study evacuation routes when a tsunami occurs due to an earthquake. Tsunami simulation means for simulating the evacuation, evacuation simulation means for simulating the evacuation situation at the time of the tsunami occurrence, tsunami occurrence situation simulated by the tsunami simulation means, and evacuation situation simulated by the evacuation simulation means The evacuation simulation means sets an evacuation start position setting unit for setting an evacuation start position for arranging an evacuation person, and an evacuation route setting for setting an evacuation route from the evacuation start position to the evacuation place And the speed at which people pass through the evacuation route And evacuation speed setting unit that sets a, characterized in that it comprises at least the set value input unit evacuation route residents can enter, a.

And a function of determining whether or not evacuation is possible through the set evacuation route.

According to the first invention, since the tsunami occurrence situation and the evacuation situation are simulated, when evacuating, it is possible to compare one's own position during the evacuation and the tsunami occurrence situation. Then, the danger of the evacuees when evacuating through the set evacuation route can be grasped. If the evacuation start position, the evacuation route, and the evacuation speed are set by the person who actually evacuates, it is possible to grasp the danger in a situation close to when a disaster actually occurs. Then, since the person (resident) who actually evacuates can be involved in setting the evacuation route, the most appropriate evacuation route for the resident can be selected. In addition, the involvement of residents in the setting of evacuation routes can change residents' awareness of disaster prevention and help them understand the importance of evacuation plans.
According to the second invention, since the tsunami occurrence situation and the evacuation situation are displayed in an overlapping manner, the danger of the evacuation route can be grasped more accurately. In addition, since the evacuation start position, the evacuation route, and the evacuation speed can be changed, it becomes easy to find an appropriate evacuation route.
According to the third invention, since the information on the building and the passage between the buildings is changed based on the information from the residents, it is possible to simulate the tsunami occurrence situation and the evacuation situation in a state that is more closely related to the lives of the residents. If the cityscape input unit has a function of inputting cityscape data from the outside, the situation of the simulation target area can be quickly reproduced.
According to the fourth invention, an evacuation route that cannot be used based on the information of the evacuation assistance tool when a wheelchair is required or when assistance of a person is required, such as evacuation of an elderly person or a disabled person Can be judged. For this reason, it is possible to set an evacuation route suitable for evacuation of elderly people and persons with disabilities who require time for evacuation.
According to the fifth aspect of the invention, a passage that cannot be passed due to the influence of a tsunami or an earthquake can be set, so that an evacuation route suitable for evacuation in an actual disaster can be studied.
According to the sixth aspect of the present invention, a route that can be used in the case of evacuation can be set although it is not used for normal traffic, and therefore an evacuation route suitable for evacuation in an actual disaster can be examined.
According to the seventh invention, in an actual disaster, a large number of people evacuate at the same time, so an evacuation route in a situation closer to the actual disaster can be set.

This is an example in which the evacuation situation data and the tsunami occurrence situation data are displayed on the display means 40 together with a plan view of the cityscape. This is an example in which the evacuation situation data and the tsunami occurrence situation data are displayed on the display means 40 together with a plan view of the cityscape. This is an example in which the evacuation situation data and the tsunami occurrence situation data are displayed on the display means 40 together with a plan view of the cityscape. It is the flowchart which showed an example of the building collapse simulation.

  The tsunami countermeasure system of the present invention is a system for simulating the situation where a tsunami arrives when a tsunami occurs due to an earthquake or the like, and the situation where an evacuation is made from a tsunami. It is characterized by having a function that enables research.

  In particular, the tsunami countermeasure system of the present invention is characterized in that it has a function that enables independent research and study of evacuation routes even by residents who do not have specialized knowledge about tsunamis. doing. For this reason, in the tsunami countermeasure system of the present invention (hereinafter referred to as the present system), residents can increase their awareness of disaster prevention by using this system and voluntarily considering evacuation routes. The effect is that an evacuation plan suitable for the area can be constructed.

  Needless to say, the application of the tsunami countermeasure system of the present invention is not limited to the application described above. For example, it can be used for earthquake and tsunami specialists (for example, firefighters, local government officials, scholars), etc., to study tsunamis and to consider city plans to minimize damage when tsunamis occur.

  Hereinafter, the tsunami countermeasure system of the present invention will be described. In the following, the function and operation of the tsunami countermeasure system of the present invention will be mainly described on the assumption that residents and others voluntarily examine evacuation routes.

  As shown in FIG. 1, the tsunami countermeasure system 1 of the present embodiment includes tsunami simulation means 10, evacuation simulation means 20, cityscape setting means 30, display means 40, and result display means 2. . The tsunami countermeasure system 1 according to the present embodiment also includes a storage unit 60 that stores information used by each unit, information input via each unit, a simulation result by each unit, and the like.

  The result display means 2 is a plan view of a cityscape (so-called general map, see FIG. 2) based on information of cityscape data, which will be described later, formed by the cityscape setting means 30, and simulation results of the tsunami simulation means 10 and the evacuation simulation means 20. Is displayed on the display means 40. That is, the result display unit 2 has a function of causing the display unit 40 to display data stored in the storage unit 60. As will be described later, the cityscape setting means 30, the tsunami simulation means 10, and the evacuation simulation means 20 may each have a function of displaying a cityscape plan view and simulation results. However, if the result display means 2 is provided separately from these means, a plan view of the cityscape and simulation results can be confirmed without activating these means. In addition, if the simulation results of the respective means are displayed on the display means 40 simultaneously, for example, by superimposing the cityscape plan view and all the simulation results, the result display means 2 independent from these means may be provided. desirable.

  The storage means 60 is a storage medium such as a hard disk or a flash memory. The equipment used as the storage means 60 is not particularly limited, but can store information supplied from the tsunami simulation means 10, the evacuation simulation means 20, the cityscape setting means 30, the display means 40, etc. What is necessary is just to have the function which can supply the predetermined information memorize | stored according to a request | requirement to each means. The storage means 60 corresponds to a storage medium or a simulation result storage unit as defined in the claims. Of course, each means may have an independent storage means, but if one storage means 60 stores all information, there is an advantage that it becomes easy to link data. .

  The display unit 40 has a function of displaying information stored in the storage unit 60 according to commands from the result display unit 2, the tsunami simulation unit 10, the evacuation simulation unit 20, and the cityscape setting unit 30. For example, the display unit 40 has a function of displaying a plan view of a cityscape (a so-called general map, see FIG. 2) and the like based on information on cityscape data to be described later according to a command from the cityscape setting unit 30. Yes. In addition, an image (see FIGS. 6 to 8) in which a plan view of the cityscape and the tsunami occurrence status are superimposed by a command from the tsunami simulation means 10, and a plan view of the cityscape and the evacuation status are superimposed by a command from the evacuation simulation means 20. The display means 40 has a function of displaying the image (see FIG. 5).

  The display means 40 is not particularly limited as long as it can display an image or the like, such as a liquid crystal display, a plasma display, or an organic EL display. However, if a touch panel in which a display and an input device are integrated is used as the display means 40, advantages such as easy input and change of various data can be obtained. For example, touch the screen to change the cityscape data in the cityscape setting means 30 (to be described later), set the evacuation start position, evacuation place, evacuation route, etc. in the evacuation simulation means 20, in other words, the object on the cityscape plan view. You can input and change by touching directly. Then, since operation becomes easy, it becomes easy for residents to use. Of course, it goes without saying that a keyboard, a mouse or the like may be used for inputting various data and the like as in the prior art.

(Cityscape setting means 30)
The cityscape setting means 30 will be described.
The cityscape setting means 30 is a means for setting a situation such as a building or a road (including a passage between buildings) in a region where simulation is performed (in other words, a region where flooding occurs due to a tsunami). That is, it is a means for setting the situation of the area where the residents etc. are evacuated, in other words, the area where the residents etc. reside. In the following, the cityscape information set by the cityscape setting means 30 is referred to as cityscape data.

The cityscape setting means 30 includes a cityscape input unit 31 that reads external information about the cityscape and forms cityscape data. This cityscape input unit 31 also has a data storage function for storing cityscape data in the storage means 60. Specifically, the cityscape input unit 31 reads information on a commercially available map that can be acquired via the Internet or the like, and creates cityscape data based on information such as buildings and roads included in the information. . For example, the base map information data provided by the Geographical Survey Institute can be acquired to create cityscape data.
As described above, if cityscape data is created by reading information on a commercially available map, there is an advantage that the cityscape can be reproduced accurately and quickly to some extent. Of course, the cityscape input unit 31 is provided with a function for inputting information on the cityscape (information on buildings, roads, etc.). Using this cityscape input unit 31, residents can input cityscape information from the beginning to obtain cityscape data. You may create it.

  The cityscape setting unit 30 includes a data changing unit 32 having a data changing function for changing the information of the cityscape data stored in the storage unit 60 and adding information. When the above-described base map information data or the like is used as the initial cityscape data, the current cityscape may have changed from the cityscape at the time when the basemap information data or the like was created. Therefore, if the data changing unit 32 changes the information of the cityscape data or adds information, the cityscape data suitable for the current cityscape can be formed.

  The data changing unit 32 has a function of forming changed cityscape data by changing or adding the following information to the cityscape data.

  For example, regarding buildings, fine adjustment of the position where the building is built, the height and width of the building, its material (wooden or reinforced concrete, etc.), and the space provided around the building (garden etc.) ) Information can be changed and added. Of course, when a building disappears or is newly constructed, it also has a function of erasing the building information to make it a vacant land or inputting new building information.

  In addition, as road information, there are functions that allow you to fine-tune the position and width of national and prefectural roads, and to change and add information such as the position and width of living passages that exist between adjacent buildings. Have. The passage for living means a passage through which automobiles and the like cannot pass but bicycles and people can pass. In other words, the passage for daily life means a passage that residents often use on a daily basis, or a passage that is not normally used but understands that people can pass normally if they are residents. In addition, the state which can pass normally here means the state which can walk at least a person facing the front, and the meaning which does not include the state where it can pass somehow if a body is turned sideways.

  Further, the data changing unit 32 is an area where a person can pass other than roads and passages for daily life, that is, an area where he / she does not normally pass but can escape through the place in case of emergency. It may have a passable area setting function having a function of setting (area). If it has such a function, it is possible to set an evacuation route in consideration of a passage that a person can use for evacuation during an actual tsunami other than a road. Then, an evacuation route suitable for evacuation in an actual disaster can be considered. For example, there is a high possibility that people can actually pass through even if they do not go in daily life, such as in a field, school yard, or house garden. Then, when setting the evacuation route, it is preferable to set such a place as a passable region because the evacuation route can be diversified and the evacuation route can be shortened.

  Further, the data changing unit 32 may change information such as the position and size of a plant such as a tree planted in a road, a park, a home garden, etc., and may add or remove a plant. It may have a function that can.

  Thus, if the cityscape data is changed by the data changing function 32, the simulation of the tsunami generation situation and the evacuation situation in the tsunami simulation means 10 and the evacuation simulation means 20 described later can be performed more accurately. In particular, if the cityscape data is changed based on information from residents, it is possible to simulate the tsunami occurrence and evacuation conditions in a more closely connected manner. Specifically, simulations can be performed based on the cityscape closest to the current situation, and evacuation using areas that can be used for evacuation that can be used for evacuation that can not be used everyday or passages that residents use daily can be considered.

  Of course, if you want to know the tsunami risk of the entire macro city (for example, calculate the expected value of the tsunami risk of the entire administrative area), you can perform sufficient simulation with the cityscape data prepared in advance. The data changing unit 32 may not be provided. However, if the tsunami countermeasure system 1 of the present embodiment is used for disaster prevention education for residents and voluntary disaster prevention measures, it is desirable to provide the data changing unit 32.

  The cityscape setting means 30 determines whether or not to form new cityscape data when the tsunami countermeasure system 1 of the present embodiment is activated, or which data among the already stored cityscape data is used, It is desirable that the display unit 40 has a function of displaying a screen for selecting the above.

  Of course, when the tsunami countermeasure system 1 of the present embodiment is activated, the cityscape image is automatically displayed on the display unit 40 based on the last used cityscape data among the cityscape data stored in the storage unit 60. You may do it. In this case, it is desirable that the display unit 40 has a function of displaying a screen for changing the cityscape data that is the basis of the cityscape image displayed on the display unit 40.

(Tsunami simulation means 10)
Next, the tsunami simulation means 10 will be described.
The tsunami simulation means 10 is a means for simulating how the inundation due to the tsunami spreads (tsunami generation situation). Specifically, a means for simulating the tsunami generation situation based on the building information stored in the cityscape data (including the cityscape data prepared in advance) set by the cityscape setting means 30 described above. is there. The tsunami simulation means 10 includes a tsunami condition input unit 12 and a tsunami simulation unit 13.

  The tsunami condition input unit 12 has a function of setting conditions for the generated tsunami. For example, it has a function to input information such as the epicenter and intensity of the earthquake that causes the tsunami, the height and speed of the tsunami that reached the coast, and the time from the occurrence of the earthquake to the coast Yes.

  The tsunami condition input unit 12 also has a function (environment setting function) for setting environmental conditions for simulating a tsunami occurrence situation. The environmental conditions set by the tsunami condition input unit 12 are not particularly limited. For example, if conditions such as wind direction, wind speed, weather (clear or rainy), temperature, humidity, etc. can be changed, the tsunami simulation unit 13 should perform a simulation under conditions closer to the actual situation. Can do. In particular, it is preferable to be able to set the tide level in the coastal area before the tsunami occurs, since the difference in the tsunami occurrence status due to the height of the tide level can be grasped.

  The tsunami simulation unit 13 generates a tsunami such as how the inundation due to the tsunami spreads when a tsunami with the condition set by the tsunami condition input unit 12 (or a tsunami generated under the set condition) approaches the coast. It has a function to simulate the situation. Further, the tsunami simulation unit 13 has a function of causing the storage unit 60 to store simulated tsunami generation status data (tsunami generation status data). Even if the tsunami and the environmental conditions are the same, the situation where the tsunami spreads varies depending on the distance between buildings, the size (height and width) of the buildings, and the arrangement of the buildings. In the tsunami simulation means 10 of the tsunami countermeasure system 1 of the present embodiment, the tsunami generation situation is simulated using the above-mentioned cityscape data, so that the tsunami occurrence situation in the set townscape can be accurately simulated.

  The method by which the tsunami simulation means 10 simulates the tsunami occurrence state, that is, the algorithm for calculating the spread of the tsunami is not particularly limited. For example, a well-known algorithm that simulates the tsunami generation status based on submarine crustal motion calculations such as the horizontal position and depth of the fault, fault size, fault direction, fault tilt, slip direction and size can do.

  In addition, when inputting information such as the epicenter and intensity of an earthquake that causes a tsunami to the tsunami condition input unit 12, the tsunami simulation unit 13 described later is based on these information and other information. Therefore, it is necessary to have a function for calculating the height, speed, arrival time, etc. of the tsunami reaching the coast. For example, the above items can be calculated if they have a calculation function such as a tsunami propagation speed equation associated with crustal deformation of the seabed and Green's law.

  Since the tsunami occurrence status data stores tsunami information and other conditions, the tsunami simulation means 10 reads the tsunami information and other conditions from the tsunami occurrence status data stored in the storage means 60. A function may be provided. If such a function is provided, simulation conditions can be easily set when performing a tsunami simulation under the same conditions as those performed in the past.

  Further, the tsunami simulation means 10 may be provided with a function of storing tsunami information and other conditions as tsunami condition data independently from the tsunami occurrence status data, and a function of reading the tsunami condition data. Also in this case, the simulation conditions can be easily set when performing a tsunami simulation under the same conditions as those performed in the past.

  In the case where the tsunami condition data is stored in the storage unit 60 independently of the tsunami occurrence status data, it is desirable to store the tsunami condition data in the storage unit 60 in such a manner that they are associated with each other. That is, it is desirable to store the tsunami condition data and the tsunami occurrence status data in association with the storage means 60 so that the tsunami occurrence status data can be retrieved from the tsunami condition data or the tsunami occurrence status data can be retrieved from the tsunami occurrence status data. .

(Evacuation simulation means 20)
Next, the evacuation simulation means 20 will be described.
The evacuation simulation means 20 is a means for simulating a situation where an evacuating person (evacuee) evacuates. Specifically, the evacuation simulation means 20 simulates a situation in which an evacuee moves after starting evacuation based on information set by each setting unit described later, and calculates the calculated evacuation situation data. It has a function of storing in the storage means 60. The evacuation status data is data including, for example, position data of evacuees when a certain time has elapsed since the start of evacuation. Information set by each setting unit, which will be described later, may also be included in the evacuation situation data as necessary.

  The evacuation simulation means 20 includes an evacuation place setting unit 21, an evacuation start position setting unit 22, an evacuation route setting unit 23, an evacuation speed setting unit 24, and an evacuation simulation unit 25.

The evacuation site setting unit 21 has a function of setting an evacuation site. The evacuation site setting unit 21 can set an evacuation site set in the area or set an original evacuation site. Then, it is possible to verify whether or not the evacuation site set in the area is safe, and it is possible to consider a more appropriate evacuation site.
The evacuation site is not necessarily the final evacuation site. For example, in the case of a bedridden person or the like, there is a high possibility that evacuation by a car or the like is necessary. In such a case, a place where a car or the like can enter, and a place closest to the evacuee's house may be set as an evacuation place.

  The evacuation start position setting unit 22 has a function of setting an evacuation start position where an evacuee is arranged. In other words, the evacuation start position setting unit 21 has a function of setting where the evacuee evacuates from. For example, when simulating from the state where the evacuees are at home, the home is set as the evacuation start position. Further, when simulating evacuation from a company, school, station, etc., each location is set as an evacuation start position.

  In the evacuation site setting unit 21 and the evacuation start position setting unit 22, the method for setting the evacuation site and the evacuation start position is not particularly limited. For example, if a touch panel is adopted as the display means 40, it is possible to set an evacuation place and an evacuation start position by displaying a cityscape image on the display means 40 and touching a predetermined building or place. . In addition, when each place and building in the cityscape is stored in the cityscape data in association with the street address or name, etc., the publicly-known input such as a keyboard is used to enter the street address or name of the place to be set as the evacuation place or evacuation start position. You may make it input using an apparatus.

  The evacuation route setting unit 23 has a function of setting an evacuation route for the evacuee to move from the evacuation start position to the evacuation site. That is, the evacuation route setting unit 23 has a function of setting which road the refugee evacuates through.

  The method for setting the evacuation route in the evacuation route setting unit 23 is not particularly limited. For example, if a touch panel is adopted as the display means 40 to be described later, a street image is displayed on the display means 40, and a route (roads, life passages, and passages) that are passed when evacuating from the evacuation start position to the evacuation site is displayed. It is also possible to set an evacuation route by tracing the area. Moreover, you may make it set an evacuation route so that an intersection may be connected by touching the intersection which passes when evacuating. Of course, a route that passes by the name of the road (for example, National Route X, XX Street, XX Highway, etc.) may be designated. In this case, the resident may give a name to the road through which the resident passes and specify the road through which the resident passes. When a route is specified by a road name, it is desirable to input the road name in the order of passing.

  The evacuation speed setting unit 24 has a function of setting a speed at which the refugee moves from the evacuation start position to the evacuation place. That is, the evacuation speed setting unit 24 has a function of setting an evacuation speed (evacuation speed) according to the refugee. For example, if the evacuation route setting unit 23 sets the evacuation speed slower when the refugee is an elderly person and sets the movement speed faster when the refugee is a youth, an appropriate evacuation suitable for each refugee is set. The situation can be simulated. The method for setting the evacuation speed is not particularly limited. For example, the evacuation speed of the refugee may be individually entered as a numerical value, or when the age of the refugee is entered, the average evacuation speed (such as fast walking) of that age may be set. When the average evacuation speed is set, it is desirable that the evacuation speed can be appropriately changed (faster or slower).

  The evacuation speed may be set constant throughout the evacuation route, but the evacuation speed may be changed according to the location of the evacuation route. If the evacuation speed is changed according to the situation of the passage of the evacuation route, the evacuation situation can be simulated more appropriately. For example, if the evacuation speed is set slower in passages that cannot be moved quickly (for example, passages that cannot be run, passages that climb stairs, places that are not paved, etc.), the actual evacuation situation A simulation close to that can be performed.

  The evacuation simulation unit 25 determines the evacuation situation based on the evacuation route set by the evacuation route setting unit 23, the evacuation speed set by the evacuation speed setting unit 24, and the cityscape data set by the cityscape setting unit 30. It has a function of simulating and storing the evacuation status data in the storage means 60. Even if the evacuation start place and the evacuation place are the same, whether or not the evacuation can be performed changes depending on how to take the evacuation route and the evacuation speed at that time. In the evacuation simulation means 20 of the tsunami countermeasure system 1 of the present embodiment, the evacuation route can be designated and the evacuation speed can also be designated using the above-mentioned cityscape data, so the evacuation situation is simulated in a form close to the actual evacuation situation. I can.

The function of setting the evacuation place, the evacuation start position, the evacuation route, and the evacuation speed in the evacuation place setting unit 21, the evacuation start position setting unit 22, the evacuation route setting unit 23, and the evacuation speed setting unit 24 is described in the claims. This corresponds to the set value input unit or set value change unit.
Of course, a set value input unit independent from the evacuation place setting unit 21, the evacuation start position setting unit 22, the evacuation route setting unit 23, and the evacuation speed setting unit 24 is provided, and the evacuation place, the evacuation start position, the evacuation route, and the evacuation speed are provided. May be set from the set value input unit.

  Further, evacuation basic data including an evacuation place, an evacuation start position, an evacuation route, and an evacuation speed, which are formed in advance, may be stored in the storage means 60, and the evacuation situation may be simulated using the evacuation basic data. . In this case, each setting part mentioned above does not necessarily need to be provided, and the function to set an evacuation place etc. does not need to be provided. However, if a function for setting the evacuation place etc. is provided in all or a part of the setting parts (or if an independent setting value input part is provided in each setting part), the evacuation place is determined based on the result of the evacuation simulation. And the like can be appropriately changed.

In addition, the timing at which the evacuees start evacuation is usually after a tsunami warning is issued after an earthquake or the like occurs. In other words, although the timing of evacuees to start evacuation is earlier than the time from the occurrence of a tsunami at the epicenter of the earthquake until it reaches the coast, a certain time has passed since the occurrence of the tsunami. As will be described later, when displaying the evacuation status data and the tsunami occurrence status data in a superimposed manner, if the result display means 2 delays the evacuation status data from the tsunami occurrence status data and starts the display, the occurrence of a tsunami The evacuation situation can be confirmed in consideration of the deviation of evacuation start.
If the evacuation situation is confirmed in consideration of such deviation, it is desirable that the evacuation simulation means 20 has a function of setting an evacuation start time, that is, a time from the occurrence of a tsunami to the start of evacuation. . In this case, by displaying the evacuation situation data and the tsunami occurrence situation data at the same time by the result display means 2, the evacuation situation can be confirmed in consideration of the tsunami occurrence and the deviation of the evacuation start.

(simulation)
Next, using the tsunami countermeasure system 1 of the present embodiment, a situation will be described in which residents and others consider an evacuation route during a tsunami.
In the following, a case will be described in which the base map information data provided by the Geographical Survey Institute is acquired and changed into cityscape data.

(Cityscape data setting)
When the tsunami countermeasure system 1 of the present embodiment is activated, the cityscape setting unit 30 forms cityscape data before simulating the tsunami occurrence situation and the evacuation situation, and causes the display unit 40 to display a cityscape plan view based on the cityscape data.

A procedure for setting cityscape data will be described with reference to the flowchart of FIG.
First, the cityscape input unit 31 of the cityscape setting unit 30 is connected to the Internet, and acquires base map information data provided by the Geographical Survey Institute. The acquired base map information data is stored in the storage unit 60 as cityscape data, and a cityscape plan (hereinafter simply referred to as a cityscape plan) based on the cityscape data is displayed on the display unit 40 (see FIG. 2). .

  In addition, when the base map information data is acquired, data including information on road edges and building perimeter lines can be acquired, so the cityscape floor plan of the cityscape data is equivalent to a general map. And shape and building arrangement and shape information can be acquired.

  When the cityscape plan is displayed on the display means 40, the cityscape input unit 31 inputs building information including coordinate data and building attributes for each building and each road on the cityscape plan. Although the method of inputting each building information is not specifically limited, For example, the following method is employable.

First, when inputting the coordinate data of a building displayed on the cityscape plan view, the corners of the building are specified in turn in a clockwise direction (or counterclockwise). The corner of the building can be specified by touching the screen or double-clicking with the pointer placed at the corner. When the corner of the building is specified, the coordinates of the corner of the building are set on the city plan and the position of the building is set.
When the position of the building is set, the building attributes (such as properties such as fire resistance and the height of the building) are input. The method for inputting the building attribute is not particularly limited, but a method of inputting the attribute using a keyboard or the like, or a method of specifying the attribute with a check box can be employed.

  When building attributes are input, building information (that is, information including building attributes and building position information) is stored in the storage unit 60.

  For each road, information such as its width and position is input, and building information including such information is stored in the storage means 60.

  And if building information is memorize | stored in the memory | storage means 60 about all the buildings and roads, the basic cityscape data will be formed.

  Here, when the building information and road information in the basic cityscape data are different from the current state, the data changing unit 32 changes the building information and road information, and the changed cityscape data is stored in the storage means 60. Is remembered.

There is no particular limitation on the method of inputting building information or road information by the data changing unit 32.
For example, if there is a building that exists on the cityscape plan but does not actually exist, the building can be deleted from the cityscape plan view by designating the building and deleting the information. In addition, a building is added when a building exists even though it is a vacant land on the cityscape plan view. The method of adding a building is not particularly limited. For example, in a cityscape plan view, a building may be added by sequentially specifying a plurality of positions and surrounding a specific area.
Further, in the base map information data, there is a possibility that there is no data up to the daily passage. Of course, there are no road areas other than roads as roads in the base map information data. Therefore, the data changing unit 32 adds a life passage and a passable area. There is no particular limitation on the method of adding a passage for living or a accessible area. For example, in a city plan, if there are roads or vacant areas that can be used as living passages or accessible areas, click the start and end points of the area to be set as a living passage or accessible area with the mouse. An area between the start point and the end point may be added as a daily passage or a passable area. Even when the daily passage and the passable area are set, the changed cityscape data including the daily pass and the passable area is stored in the storage unit 60.

When the cityscape data has already been formed and the cityscape data is stored in the storage means 60, the cityscape setting means 30 reads the cityscape data to be used from the storage means 60 and based on the cityscape data. A city plan view is displayed on the display means 40.
Moreover, when adding a change to the read cityscape top view, it can be changed by the data changing unit 32 in the same manner as described above (see FIG. 3B).

(Tsunami simulation)
When cityscape data is formed by the cityscape setting means 30, the tsunami simulation means 10 is implemented using the cityscape data.

First, the tsunami simulation means 10 reads cityscape data.
Next, when conditions such as tide level, wind direction, and wind speed are set by the tsunami condition input unit 12, a tsunami simulation is performed by the tsunami simulation unit 13.
Then, tsunami occurrence status data that is a simulation result by the tsunami simulation unit 13 is formed, and this tsunami occurrence status data is stored in the storage unit 60.

(Evacuation simulation)
When the cityscape data is formed by the cityscape setting unit 30, the evacuation simulation unit 20 executes an evacuation simulation.

The procedure of the evacuation simulation will be described with reference to the flowchart of FIG. 4B and FIG.
First, the evacuation simulation means 20 displays a cityscape plan on the display means 40 based on the cityscape data.

  Next, an evacuation place EP that is a destination to be evacuated is set by the evacuation place setting unit 21, and an evacuation start position SP is set by the evacuation start position setting unit 22. Of course, the evacuation place EP may be set after setting the evacuation start position SP.

  When the evacuation start position SP is set, the evacuation route ER is set by the evacuation route setting unit 23. The evacuation route ER can be set by various methods as described above. For example, a route to the evacuation site EP can be set in the order of a road coming out from the building at the evacuation start position SP, a road connected to the road, and a road moving from the road.

  When the evacuation route ER is set, the evacuation speed setting unit 24 sets the evacuation speed. The evacuation speed may be the same for all evacuation routes, or the evacuation speed may be changed depending on the road or location on the evacuation route ER.

  When the setting of the evacuation speed is completed, the evacuation simulation unit 25 performs an evacuation simulation. Then, evacuation situation data which is a simulation result by the evacuation simulation unit 25 is formed, and this evacuation situation data is stored in the storage means 60.

(Result display)
When the simulation by the tsunami simulation means 10 and the evacuation simulation means 20 is completed, the result display means 2 displays the evacuation situation data and the tsunami occurrence situation data on the display means 40 together with the cityscape plan view. Specifically, the movement status of the evacuees based on the evacuation status data and the tsunami occurrence status based on the tsunami occurrence status data are displayed on the display means 40 as moving images. Then, the situation where the tsunami spreads after the tsunami occurs (that is, the occurrence of inundation due to the tsunami) and the relative positional relationship of the evacuees can be grasped with images, so the user can sense the evacuation situation It will be easier to grasp.

6 to 8, when the evacuation situation data and the tsunami occurrence situation data are displayed on the display means 40 together with the cityscape plan view by the result display means 2 for the two evacuation routes ER1 and ER2 shown in FIG. Is shown.
6-8, the hatched part has shown the place where the flooding by the tsunami produced.

  As shown in FIG. 6, it is assumed that the evacuees do not evacuate for a certain period of time after the occurrence of the tsunami.

  As shown in FIG. 7, the distance between the refugee and the tsunami changes after a certain time has elapsed since the refugee started evacuation on the evacuation routes ER1 and ER2. However, at the time of FIG. 7, the distance between the refugee and the tsunami is not so different between when evacuating the evacuation route ER1 and when evacuating the evacuation route ER2.

  However, when the tsunami spreads further, as shown in FIG. 8, the refugees passing through the evacuation route ER1 are sufficiently separated from the tsunami, whereas the refugees passing through the evacuation route ER2 have reached the tsunami. You enter the area and you can evacuate only to the position of ×.

  The two evacuation routes ER1 and ER2 can visually grasp that the evacuation route can be evacuated by one evacuation route and the other evacuation route cannot be evacuated even though the moving distance from the evacuation start position SP does not change so much. That is, in the tsunami countermeasure system 1 according to the present embodiment, the user can easily understand the evacuation situation.

  In the example described above, the case where the tsunami simulation is performed first has been described, but either the tsunami simulation or the evacuation simulation may be performed first. If the evacuation route is to be considered after looking at the results of the tsunami simulation, the tsunami simulation may be performed first. In addition, if it is necessary to confirm a sense of evacuation, an evacuation simulation may be performed first.

(Additional functions)
The tsunami countermeasure system 1 of the present embodiment can simulate evacuation in a tsunami in a more realistic situation if it has the following functions in addition to the functions described above.

(Building collapse simulation)
A tsunami is usually caused by an earthquake, but if an earthquake occurs, the building may collapse or a landslide may occur, blocking the passage and making it impossible to pass. Then, even if evacuation is simulated when the building is not collapsed, there is a possibility that evacuation cannot be performed when an actual tsunami occurs. For example, even if you can evacuate to an evacuation route on the way, if the building is collapsed in front of the evacuation passage (that is, the evacuation route between the current position and the evacuation site), you will not be able to proceed any further. . In this case, there is a high possibility that evacuation after reaching the passage blocked by the collapse of the building will be difficult. In other words, when a building is collapsed in front of an evacuation passage, it is necessary to consider an evacuation route assuming that situation.

  Therefore, it is preferable that the tsunami simulation means 10 includes a building collapse simulation unit 14 having a function of simulating whether a building is collapsed by an earthquake or whether a passage is blocked by a collapse of the building. Specifically, the building collapse simulation unit 14 uses the seismic source and the intensity of the earthquake (seismic intensity) input from the tsunami condition input unit 12 and inputs the seismic intensity based on the building information stored in the cityscape data. Has a function of simulating whether the building collapses or not. If such a building collapse simulation unit 14 is provided, it is possible to grasp a passage that may become unusable during an evacuation, so that a more appropriate evacuation simulation can be performed.

  For example, the building collapse simulation unit 14 calculates a building to be collapsed and a passage blocked by the collapse of the building, and stores the calculated information in the storage unit 60 as collapse data. Then, in accordance with a command from the tsunami simulation means 10, the collapse data is displayed on the display means 40 together with a plan view of the cityscape and an image in which the tsunami occurrence state is superimposed. In addition, the evacuation status is also displayed on the display unit 40 in accordance with commands from the evacuation simulation unit 20 together with these images. Then, you can check whether there is a collapsed building etc. on the evacuation route, so you can judge whether the set evacuation route can be used when a tsunami occurs, which is suitable when an actual tsunami occurs Evacuation routes can be considered.

  The method by which the building collapse simulation unit 14 simulates the collapse of the building, that is, the algorithm for calculating the collapse of the building is not particularly limited. For example, building collapse in each passage can be simulated based on the collapsed building algorithm shown in FIG. In other words, using the seismic intensity level as a parameter, it is possible to calculate the number of buildings to be collapsed in each passage by giving a collapse probability depending on the age at which the wooden building was built. And if the number of collapsed buildings in each passage becomes a certain number or more (for example, three or more buildings), it can be determined that the passage cannot pass (is blocked) due to the collapse of the building. Note that the number of buildings to be collapsed can be obtained probabilistically using the assumed seismic intensity floor and the buildings of each age existing in the passage and their collapse rates as parameters.

  Also, without providing the building collapse simulation unit 14, collapse data in which a building to be collapsed and a passage blocked by the building to be collapsed are set in advance is stored in the storage means 60. Based on this collapse data, tsunami simulation means is stored. 10 may cause the display unit 40 to display the collapsed data. In this case, the collapse data may be data that simulates a building collapsed due to an earthquake and its collapse situation in advance, or a person who uses the tsunami countermeasure system 1 uniquely (that is, based on experience and usual circumstances). ) Data created by designating the building to collapse may be used.

  A function (prevention place setting function) for setting a passage to be blocked in advance as described above may be provided in the tsunami simulation means 10. Then, if the location where traffic is hindered by a tsunami or earthquake can be grasped, the passage can be removed from the evacuation route in advance. For example, if it is assumed that a place where a landslide is expected to occur due to an earthquake or the like cannot be passed in advance, an evacuation route that does not use the passage can be considered. Then, an evacuation route suitable for evacuation in an actual disaster can be considered.

(Evacuation judgment means 50)
In the above example, the evacuation situation simulated by the evacuation simulation means 20 is displayed on the display means 40 so as to overlap with the plan view of the cityscape, the tsunami occurrence situation, the collapse data, etc. Judging. That is, the person determines whether or not evacuation is possible by looking at the image displayed on the display means 40. However, in this case, there is a possibility that the subjectivity of the person who saw the image will be included in the judgment of evacuation, and it may not be possible to properly judge whether or not evacuation is possible.

  Therefore, an evacuation determination unit 50 may be provided for determining whether or not evacuation is possible using the set evacuation route. In this case, it is possible to present an objective judgment as to whether or not evacuation by the evacuation route is possible, so that an appropriate evacuation route can be considered.

  The method by which the evacuation determination unit 50 determines whether or not evacuation is not particularly limited, but for example, the following method can be used to determine whether or not evacuation is possible. First, based on the evacuation status data, when the set evacuation route cannot reach the evacuation place within a predetermined time, it can be determined that the evacuation route cannot be evacuated. Further, based on the collapse data and the evacuation status data, when the evacuation route is blocked by a building or the like, the passage cannot pass, and therefore it can be determined that the evacuation route cannot be evacuated.

  The method by which the evacuation determination unit 50 displays whether or not evacuation is possible is not particularly limited. For example, if evacuation cannot be performed with the set evacuation route, “NG” may be simply displayed. In addition, when the evacuation route is blocked by a building or the like, the evacuation route may be displayed only up to that position by a command from the evacuation determination means 50. That is, the image may indicate that the set evacuation route can only evacuate to that position.

(When many people evacuate)
In the above example, the case where the evacuation determination unit 50 determines whether or not evacuation can be performed due to an environmental factor (passage situation or tsunami occurrence situation) when one refugee evacuates has been described. .

  However, when an actual tsunami occurs, many people will be evacuated at the same time. Even in the case of the above example, it is also possible to predict whether or not evacuation is possible with a certain degree of accuracy in a situation where a large number of people evacuate by reducing the evacuation speed of the refugees. However, it is desirable to be able to judge the situation in which a large number of people are evacuating at the same time in a manner close to actual evacuation.

  For example, evacuation status data obtained by setting a evacuation route by each of a plurality of people is stored in the storage unit 60 in association with the set tsunami condition data. And the evacuation judgment means 50 judges whether the evacuation by the set evacuation route is possible based on the plurality of evacuation situation data when the tsunami of the same condition occurs. Then, since it is determined whether or not evacuation is possible through an evacuation route based on the evacuation status of a plurality of evacuees, it is possible to determine whether or not evacuation is possible in a form closer to actual evacuation.

In this case, the method for determining whether or not evacuation is possible using the set evacuation route is not particularly limited. For example, whether or not evacuation is possible can be determined by the following method.
First, if multiple evacuees enter the same passage at the same timing based on multiple evacuation status data, determine whether multiple refugees can pass simultaneously based on information on the passage in the cityscape data To do. If a plurality of evacuees cannot pass simultaneously, it can be determined that the evacuation route cannot be evacuated. When determining whether or not evacuation is possible in this way, the evacuation determination means 50 may determine the number of evacuees who can pass simultaneously from the information on the width of the passage of the cityscape data. It is preferable that the number of people who can move along the passage at the same time is included in advance.

  In addition, when multiple evacuees enter the same passage at different timings, and the evacuation speed of the evacuee who has already entered the passage earlier than the evacuation speed of the refugee who has entered the passage later, It can be determined that the evacuation route cannot evacuate. In the case of a passage where multiple people can pass, an evacuee whose evacuation speed is slower than an refugee who has entered the passage later has already entered the passage, and the number of refugees who have a slower evacuation speed If there are more people than can pass through the passage at the same time, it can be determined that the evacuation route cannot be evacuated.

  Note that even when the evacuation determination unit 50 determines whether or not the evacuation determination unit 50 can evacuate assuming a situation in which a large number of people have evacuated, the method by which the evacuation determination unit 50 displays whether or not evacuation is possible is not particularly limited. For example, if there is an evacuee who cannot evacuate on the set evacuation route, it may simply display “NG”. Further, only the evacuation route of the evacuees who cannot evacuate may be displayed only up to the position where the evacuation can not be evacuated according to the command from the evacuation judgment means 50.

  If the evacuation determination unit 50 is not provided, a plurality of evacuation status data may be displayed on the display unit 40 at the same time. Even in this case, since movements of a plurality of evacuees can be grasped at the same time, it is possible to evaluate whether or not the evacuation route set by each evacuee can be evacuated.

(Judgment based on evacuee information)
In some areas, there are evacuees who can only move in wheelchairs or bedridden evacuees (hereinafter referred to as care recipients). The assistance of other people is required to evacuate those who need care. Moreover, when a refugee who needs care evacuates, there is a possibility that it cannot pass even in a passage through which a healthy person can pass. Therefore, the evacuation determination unit 50 may be provided with a function for determining whether or not a care-required refugee can evacuate according to the set evacuation route.

  There is no particular limitation on the method for determining whether a refugee who needs care can be evacuated. For example, the following method can be employed.

First, information on an evacuation assistance tool required when an evacuation target person evacuates is stored in the storage means 60 (corresponding to an evacuation assistance tool storage unit in claims).
On the other hand, the evacuation simulation means 20 is provided with an evacuation target person input unit 26 for inputting or selecting information unique to the evacuee (that is, information on the evacuation assistance tool). Then, evacuation status data including information specific to the evacuee input or selected by the evacuation target person input unit 26 is stored in the storage unit 60.
Then, the evacuation determination means 50 determines whether or not an evacuee can evacuate the passage included in the set evacuation route based on the evacuation situation data.

  If it is determined whether the refugee who needs care is allowed to evacuate by the method described above, an evacuation route that cannot be used can be appropriately determined based on the information of the evacuation assistance tool. Then, it is possible to set an evacuation route suitable for evacuation of elderly people and persons with disabilities who need time for evacuation.

  For example, consider a case where an evacuee can move to an evacuation site in a short time by using stairs, but can move to an evacuation site even on a detour, although it is a detour. In this case, in the case of a refugee who is inconvenient, he / she inputs to the evacuation subject input unit 26 that his / her foot is inconvenient and selects or inputs a cane or a wheelchair as an evacuation assist tool. Then, when the information that the wand is used is included in the evacuation status data, the evacuation determination unit 50 determines that evacuation is possible even if an evacuation route that passes through the stairs is selected. On the other hand, when the information that the wheelchair is used is included in the evacuation situation data, the evacuation determination unit 50 determines that evacuation cannot be performed when the evacuation route that passes through the stairs is selected. That is, since the evacuation determination means 50 determines whether or not evacuation can be appropriately performed according to the refugee based on the information on the passage and the evacuation status data, the appropriate evacuation route corresponding to the state of the refugee should be considered. Will be able to.

  If the evacuation person can move regardless of the situation of the passage if there is only one person who assists, the person who assists selects or inputs one person as an evacuation assistance tool. Then, when an evacuation route that can be passed only by one person is selected, the evacuation determination means 50 determines that evacuation is impossible, so that an evacuation route suitable for an evacuee who needs assistance can be considered.

  If evacuation status data including information specific to the refugee is accumulated, the residents can share information on where the refugee requiring care lives. It is also possible to determine residents to assist care recipients and to examine appropriate evacuation routes for the residents to assist.

  The information specific to evacuees described above is not particularly limited. For example, you can list information such as whether you are physically disabled or whether you can walk on your own, but it contains information necessary for life after evacuation, such as the physical condition of the evacuees requiring care (hypertension and pre-existing conditions). May be.

  Information on the evacuation assistance tool is not particularly limited. For example, it is preferable to include not only tools such as wheelchairs, walking sticks and stretchers necessary for the movement of evacuees but also information on devices (for example, oxygen inhalers) that assist the activities of evacuees.

  The tsunami countermeasure system of the present invention is suitable as a system for residents to voluntarily investigate and study local disaster prevention measures.
