Description

  The present invention relates to an evacuation route search system that searches for an evacuation route to an evacuation site when an abnormal situation such as a disaster occurs or is predicted.

  Conventionally, when a dispatch command is issued to an emergency vehicle such as a fire engine or an ambulance, a system for searching a route from a dispatch station to a destination and displaying the route on a map has been proposed (for example, Patent Document 1).

  However, there is no system that searches for routes for residents to evacuate to evacuation sites (for example, various facilities such as parks, schools, and public halls) when an abnormal situation such as a disaster occurs or is predicted. Is the actual situation. For this reason, if an abnormal situation occurs or is predicted, the residents have to choose an evacuation route based on their own judgment and follow the route to evacuate.

JP 2002-156902 A

  Here, one or a plurality of the evacuation sites are set in an area divided within a predetermined range, and there are a large number of buildings such as houses associated with evacuation to individual evacuation sites. For this reason, inhabitants of a large number of buildings are evacuated in one evacuation site, and the scale is about several tens to several hundreds.

  Then, as described above, if residents and the like freely select an evacuation route by self-judgment, there is a possibility that evacuees may concentrate on a specific evacuation route. In addition, in the situation where the region is confused due to the occurrence of an abnormal situation or its prediction, even if the evacuation site itself can be grasped, if you evacuate without confirming the route, you will get lost along the way There is also a fear.

  Furthermore, if the road on the route is congested due to concentration of evacuees or there are areas where traffic is prohibited, it may not be possible to follow the route that the evacuated inhabitants had in mind. It is difficult to understand the degree of traffic and prohibited areas in the pre-evacuation situation.

  SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an evacuation route search system that can appropriately guide an evacuee to an evacuation place when an abnormal situation such as a disaster occurs or is predicted.

  The present invention employs the following means in order to solve the above problems.

  That is, in the first invention, in an area including an evacuation place at the time of occurrence of an abnormal situation and a large number of buildings associated with evacuation to the evacuation place, the evacuation place from each building existing in the area. An evacuation route search system for searching an evacuation route to a building registration means for pre-registering a building for which a route search is requested among the many buildings existing in the region, and the region An abnormal situation information acquisition unit that acquires abnormal situation information, a map information storage unit that stores map information of the area, and an evacuee of the registered building based on the map information when the abnormal situation information is acquired Evacuation route search means for searching for an evacuation route to the evacuation site, and first information transmission means for transmitting the evacuation route information selected by the search to each registered building.

  According to the first aspect of the invention, when the abnormal situation information based on the occurrence or prediction of an abnormal situation is acquired, the evacuation route search means searches for an evacuation route to the evacuation site for refugees in the registered building. The first information transmitting means transmits the evacuation route information selected by the search to each registered building. In each registered building that has received the information, if the evacuation route is presented to the refugee existing in the building, the refugee can grasp the evacuation route to the evacuation site. Thereby, it is possible to suppress the occurrence of problems that may occur when an evacuee selects an evacuation route by self-judgment.

  In addition, every time there is a search request from an evacuee of a building existing in the area, the evacuation route is not searched every time, but the evacuation route search for the evacuee of each registered building is performed on one system. It will be done together. For this reason, routes are allocated so that evacuees do not concentrate on specific evacuation routes, and various information that cannot be grasped only by existing in buildings (for example, the degree of congestion of roads) and attributes of evacuees are also considered. It is possible to search for an evacuation route. Thereby, an evacuee can be appropriately guided to an evacuation place.

  In the second invention, the building registration means also registers the number of evacuees in each registered building, and the evacuation route search means ensures that the number of evacuees is less than a predetermined number in one evacuation route. Search for evacuation routes.

  According to the second invention, since a large number of evacuees do not concentrate on one evacuation route, the evacuee can move smoothly to the evacuation site. When evacuating, many evacuees select the shortest route or the road that they normally use, and the evacuees tend to concentrate on a specific road. Therefore, there is a great merit in performing the sort by the number of people.

  In this case, the predetermined number of persons is determined in consideration of various circumstances such as the width of the road serving as an evacuation route, the width of the sidewalk if the road and the sidewalk are separated, and the amount of traffic of the vehicle.

  In the third invention, the building registration means also registers the attributes of the refugees in each registered building, and the evacuation route search means for the buildings where the refugees having specific attributes are registered, The shortest route between the building and the evacuation site was searched.

  According to the third aspect, since the shortest route is searched for the refugee having a specific attribute, it is possible to avoid the search from the evacuation route that goes around to the evacuation site and increase the burden. In this case, the specific attribute may be an attribute that is difficult to move quickly by walking compared to a normal person, for example, an elderly person, an infant, a pregnant woman, a disabled person, and the like.

  In a fourth aspect of the present invention, road information acquisition means for acquiring road information of the area is further provided, and the evacuation route search means searches for the evacuation route based on the map information and the road information.

  According to the fourth aspect of the invention, for example, the evacuation route is searched in consideration of road information such as the degree of congestion of the road and the presence of a prohibited road, so that a more appropriate evacuation route can be searched. The evacuation route from a non-registered building is congested, or part of the route is a prohibited road, making it difficult to evacuate along the evacuation route unexpectedly. Can be avoided.

  In a fifth aspect of the invention, the abnormal situation information includes information on whether or not evacuation using a vehicle is possible, and the evacuation route search means is based on the map information and road information when the vehicle is usable. The evacuation route when using a vehicle is searched.

  According to the fifth invention, in each registered building, not only the evacuation route by foot but also the evacuation route at the time of using the vehicle is presented to the refugee, the refugee can receive information on the availability of the vehicle and the vehicle. The evacuation route when using it can be grasped. If there is a person with the specific attribute mentioned above or there is an evacuation site at a distance of several kilometers or more, it is difficult for the refugee to receive the vehicle availability and the evacuation route when possible. Useful. Moreover, since the evacuation route is searched in consideration of road information (for example, the degree of traffic congestion and the existence of prohibited roads) when using the vehicle, evacuation along the evacuation route is unexpectedly difficult even when the vehicle is moving. Can be avoided.

  In a sixth aspect of the present invention, a route information acquisition unit that is installed in each registered building and acquires the evacuation route information; and the evacuation route that is installed in each registered building and is based on the evacuation route information is represented by a map of the region. Display means for displaying on the information.

  In the sixth aspect of the invention, the display means installed in the registered building displays the evacuation route selected by the search together with the map information. You can grasp the route at a glance. Thereby, the convenience can be improved.

  In a seventh aspect of the present invention, the information processing apparatus further includes second information transmitting means for transmitting the evacuation route information to a mobile terminal possessed by an refugee in each registered building.

  According to the seventh aspect, the mobile terminal can display the evacuation route on the screen. Since the evacuees can evacuate while looking at the evacuation route displayed on the mobile terminal, it is possible to avoid getting lost during the evacuation and forgetting the evacuation route.

  In an eighth aspect of the present invention, the apparatus further comprises a detection unit that is installed in the area and detects a body surface temperature of a passerby, the abnormal situation information includes occurrence information of an infectious disease, and the evacuation route search unit includes The evacuation route is searched by the detection means so as to avoid a road on which a person having a body surface temperature equal to or higher than a predetermined value passes.

  According to the eighth aspect of the invention, when an abnormal situation occurs due to the occurrence of an infectious disease, the refugee can evacuate while avoiding the road on which a person having a body surface temperature equal to or higher than a predetermined value passes. A person with a high body surface temperature, that is, a high fever, is likely to have an infection. For this reason, when the passerby possesses the virus, the risk of the virus being infected during evacuation can be reduced.

The figure which shows the outline of the whole area, and an evacuation route. The block diagram which shows the electrical constitution of a system.

  An embodiment of an evacuation route search system will be described below with reference to the drawings. This evacuation route search system is a system that searches an evacuation route (evacuation route) from a pre-registered building to an evacuation site associated with the building and notifies the resident of the registered building of the evacuation route.

  Here, the registered building is assumed to be a large number of houses built in a residential lot, and the evacuation site is assumed to be an elementary school that includes the residential lot in the school area. FIG. 1 is a diagram showing an overall outline of an area including the residential lot and an elementary school. Incidentally, in FIG. 1, the searched evacuation route is also shown.

  As shown in FIG. 1, the area X includes a residential lot 11 and an elementary school 12. A large number (for example, about several tens of houses) of individual houses 21 are built in the residential lot 11. Each house 21 is divided into a plurality of house blocks 22 (a first block 22a, a second block 22b, and a third block 22c). In the residential lot 11, a plurality of doorways 13 are provided. In addition, a management center 23 that performs various management tasks in the residential lot 11 such as crime prevention is also installed in the residential lot 11.

  The elementary school 12 is an evacuation place associated with each house 21 in the residential lot 11. A plurality of entrances 14 for entering and exiting the site of the elementary school 12 (two in the figure, a first entrance 14a and a second entrance 14b) are provided.

  Next, the configuration of the evacuation route search system will be described. FIG. 2 is a block diagram showing the electrical configuration of the system.

  The evacuation route search system includes a management server 31 as evacuation route search means. The management server 31 has a microcomputer composed of a CPU and the like, and is installed in the management center 23 of the residential lot 11. The management server 31 performs various controls for searching for a slammed route from the residential subdivision 11 to the elementary school 12 based on the road information of the region X and the like.

  The management server 31 has a storage unit 31a. The storage unit 31a stores map data including roads and the like provided in the region X, and building registration data in which the houses 21 of the residential subdivision 11 serving as the departure point of the evacuation route are registered. In addition, the number of residents residing in each house 21 (that is, the number of evacuees) and the attributes for each resident are also registered with the building registration data. By the way, the attribute of the resident refers to such things as gender (male or female), elderly (for example, over 75 years old), whether or not pregnant, whether or not there is a disability.

  Registration of data such as pre-registration of these houses 21, the number of residents, and attributes of residents is performed by an input operation using the operation unit 32 of the management server 31. For this reason, you may make it register only the house 21 with which the registration request was requested | required among each house 21 of the house subdivision 11. In this embodiment, the storage unit 31a for storing map data corresponds to a map information storage unit, and the management server 31 and the operation unit 32 correspond to a building registration unit.

  Various devices are connected to the management server 31. As one of them, an external communication device 33 is connected. The external communication device 33 can communicate with an information providing organization J (for example, an administrative organization such as a prefectural municipality or the police) through a public communication network such as the Internet or wireless. Through the communication, the management server 31 acquires disaster information for the region X from the information providing organization J. Disaster information refers to information such as evacuation instructions and evacuation recommendations issued to notify the occurrence of various disasters such as earthquakes, wide-area fires, floods, tsunamis, and earth and sand, and to predict the occurrence of such disasters. is there. This disaster information corresponds to abnormal situation information.

  In addition, a specific road may be designated as a prohibited road due to the occurrence of a disaster or its prediction. The management server 31 also acquires information about such a closed road and road information such as vehicle traffic information from the information provider J through the external communication device 33.

  In addition, a monitoring camera 34 is connected to the management server 31. A large number of surveillance cameras 34 are installed on roads in the region X so that the entire road in the region X is covered as an image acquisition range. As its installation mode, for example, it is installed using a utility pole, a new installation pole, etc. at intervals of about several to 10 m along the road. Each surveillance camera 34 is assigned a device address, and each device address is associated with the map information of the region X. For this reason, the management server 31 can grasp which location in the region X the output destination of the image information corresponds to by the device address.

  Then, the monitoring camera 34 always shoots the surrounding roads installed, and outputs the captured image information to the management server 31. The management server 31 analyzes this image information to grasp the road conditions included therein. For example, there are situations such as congestion of people and vehicles, traffic jams, and situations where rubble or the like has accumulated on the road due to a disaster, making it difficult to pass.

  In this embodiment, the management server 31 and the external communication device 33 correspond to an abnormal situation information acquisition unit and a road information acquisition unit. The surveillance camera 34 also corresponds to road information acquisition means.

  Next, the home server 41 installed in each house 21 of the house subdivision 11 is connected to the management server 31, and the evacuation route information (evacuation route information) selected by the search is sent to each home server 41. Output individually. For this reason, the management server 31 corresponds to a first information transmission unit, and the home server 41 corresponds to a route information acquisition unit. Each home server 41 includes a microcomputer including a CPU, various memories, and the like, and map information of the region X is stored in the memory.

  Each home server 41 is connected to a wireless communication unit 43 and a home monitor 42, and the home server 41 controls the operation of the wireless communication unit 43 and the home monitor 42. Based on the evacuation route information received from the management server 31, the evacuation route to the elementary school 12 is displayed on the home monitor 42.

  The home monitor 42 as a display means is installed on the living wall surface of each house 21, and the home server 41 displays the evacuation route on the map information of the region X based on the evacuation route information acquired from the management server 31. The wireless communication unit 43 can perform wireless communication with a mobile terminal T such as a mobile phone owned by a resident of each house 21, and the home server 41 uses the wireless communication unit 43. The evacuation route information is output to the mobile terminal T. For this reason, the home server 41 and the wireless communication unit 43 correspond to a second information transmission unit. The mobile terminal T displays the evacuation route on the display monitor Ta together with the map information of the region X based on the evacuation route information.

  Next, various control processes executed by the management server 31 and the home server 41 in this route search system will be described.

  Triggered by the acquisition of disaster information for the region X from the information provider J, the management server 31 searches for an evacuation route from each house 21 of the residential subdivision 11 to the elementary school 12 that is an evacuation site. . When searching for this evacuation route, the management server 31 considers the following first to fifth items based on the map information of the region X.

  That is, first, the distance to the elementary school 12 (specifically, the entrance / exit 14) is made as short as possible. Second, avoid roads crowded with evacuees and vehicles. Third, avoid roads designated as non-traffic. Fourthly, one evacuation route should not exceed the set upper limit (for example, about 60 people). Fifth, prevent multiple evacuation routes from overlapping in part.

  Among these, the upper limit of the number of evacuees in the fourth item takes into account various circumstances such as the size of the road that serves as the evacuation route, the size of the sidewalk if the road and the sidewalk are separated, and the traffic volume of the vehicle To be determined.

  Regarding the house 21 in which an attribute having a specific attribute among the resident attributes is registered, the consideration is performed by searching for the route in consideration of only the first matter among the aforementioned matters. As the specific attribute, for example, an elderly person, an infant, a pregnant woman, a disabled person, and the like can be considered. This is because when an evacuee having these attributes is included, the priority should be given to selecting the evacuation route with the shortest distance rather than distributing the evacuation route.

  An example of route search performed in consideration of these matters will be described with reference to FIG. Here, it is assumed that the following items are registered as the number of evacuees and resident attributes. First, it is registered in advance that there are about 50 residents (refugees) in each housing block 22 of the residential lot 11. It is assumed that there are about four residents in each house 21. In one house 21a belonging to the third block 22c, there are elderly residents, and their attributes are registered in advance.

  Further, as road conditions in region X, there are a congested road 51 that is crowded with vehicles and refugees to elementary school 12, and a prohibited road 52 that is closed, and the management server 31 grasps the presence as a road condition. Suppose you are. Such road information is acquired from the information providing organization J or is grasped based on the captured image information of the monitoring camera 34.

  As shown in FIG. 1, different evacuation routes R <b> 1 to R <b> 3 are assigned to each housing block 22 as an evacuation route R from the residential lot 11 to the first doorway 14 a of the elementary school 12. For the first evacuation route R1 assigned to the house 21 of the first block 22a, the route that is the shortest to the elementary school 12 is selected using the doorway 13a corresponding to the first block 22a. Here, another evacuation route R4 that uses another doorway 13b to reach the second doorway 14b of the elementary school 12 is also the shortest, but is excluded because the evacuation route R4 includes the congested road 51. ing.

  The second evacuation route R2 assigned to the house 21 of the second block 22b uses the doorway 13c corresponding to the second block 22b, and is the shortest route to the elementary school 12 and does not overlap with the first evacuation route R1. Selected.

  For the third evacuation route R3 assigned to the house 21 of the third block 22c, a route that is not the shortest to the elementary school 12 but a little detour is selected using the doorway 13d corresponding to the third block 22c. This is because the road does not overlap the first evacuation route R1 and the second evacuation route R2 and avoids the prohibited road 52. However, with respect to the house 21a in which elderly residents exist, the branch route Ra that branches the third evacuation route R3 on the way is selected. In this case, even if it partially overlaps with the second evacuation route R2, the shortest distance is given the highest priority.

  As described above, according to this embodiment, the following advantageous effects can be obtained.

  (1) When disaster information is issued from the information providing organization J, the evacuation route R to the elementary school 12 that is an evacuation site is displayed on the home monitor 42 of each house 21 in the residential subdivision 11. Thereby, the resident of the house 21 can grasp the evacuation route R to the elementary school 12 at a glance. The evacuation route R is also displayed on the mobile terminal T such as a resident, and the resident can evacuate while looking at the evacuation route displayed there. As a result, it is possible to avoid forgetting the evacuation route R and getting lost during the evacuation.

  (2) When searching for the evacuation route R, the evacuation route R for each house 21 of the residential subdivision 11 is collectively performed on one system, not for each building individually. Therefore, the evacuation route R can be searched by assigning the evacuation route R, considering road information such as the degree of congestion, and the attributes of the residents. Thereby, a resident can be appropriately guided to the elementary school 12.

  (3) Different evacuation routes R1 to R3 are allocated in the blocks 22a to 22c of the residential lot 11. In each of these evacuation routes R1 to R3, since the upper limit of the refugee is set, it is possible to avoid the concentration of evacuation of residents on the specific evacuation route R.

  (4) For the house 21a in which the resident attributes are registered in advance and the elderly resident is present, the shortest route (the route including the branch route Ra) to the elementary school 12 is searched. For this reason, the third evacuation route R3 that makes a detour to the elementary school 12 is searched, and the burden on the elderly can be prevented.

  (5) The evacuation route R is searched in consideration of road information such as the congested road 51 and the prohibited road 52 acquired from the monitoring camera 34 and the information providing organization J. Therefore, it can be avoided that evacuation along the evacuation route R becomes unexpectedly difficult due to the presence of the traffic jam road 51 and the traffic prohibition road 52. Thereby, a more appropriate evacuation route R can be searched.

  Note that the present invention is not limited to the embodiment described above, and can be implemented, for example, in the form shown as another example below.

  (A) In the above embodiment, the house 21 of the residential lot 11 is assumed as a registered building. However, in the region X, a house (including a collective housing), a commercial building, a store, etc. existing outside the residential lot 11 The building may be registered based on the request of the user. In addition to the building registration, the number of evacuees and attributes registered together with the building registration are registered using the operation unit 32 of the management server 31. In this case, since the entire building existing in the region X is to be registered, the management server 31 may be installed not in the management center 23 of the residential subdivision 11 but in a common facility such as a public hall in the region X. Furthermore, it is also possible to apply to an area where the residential lot 11 does not exist.

  (B) In the above embodiment, the elementary school 12 including the residential subdivision 11 in the school area is assumed as an evacuation site. However, the evacuation site includes various facilities such as parks, public halls, and hills during disasters such as tsunamis. It is. Normally, an evacuation site is designated in advance, but a temporary evacuation site may be set depending on the scale and type of disaster. In such a case, since the temporary evacuation place is included in the disaster information, the evacuation route R may be searched by setting the place for the purpose.

  (C) In the above embodiment, the number of residents (the number of evacuees) and attributes are registered for each registered house 21, but the registration is not essential. This is because, even if the number of people and attributes are not grasped, the route search considering the route of the evacuation route R and the road information is possible. However, if these registrations are made, it is preferable in that a route search such as limiting the number of evacuees assigned to one evacuation route R or prioritizing the shortest route for a specific attribute is possible.

  (D) In the above embodiment, registration of data such as the pre-registration of the houses 21, the number of residents, and the attributes of the residents is performed by an input operation using the operation unit 32 of the management server 31. You may make it register by. In this case, registration is performed using an input operation unit provided in the home server 41, and the registration information is transmitted to the management server 31. The building registration means is configured by the home server 41 and its input operation unit.

  (E) In the above embodiment, the explanation is mainly made on the assumption of evacuation by walking. However, if the disaster information includes information on whether or not evacuation using a vehicle is possible, the vehicle can be used. For example, the evacuation route R when using the vehicle may be searched. In the case of a vehicle, since it is easily affected by traffic jams and traffic prohibitions, it is preferable to search for an evacuation route R in consideration of not only map information but also road information regarding the presence of traffic jam roads 51 and traffic prohibition roads 52.

  As a result, if there is a person with the specific attributes (elderly, etc.) mentioned above, or if there is an evacuation site at a distance of several kilometers or more, whether or not the vehicle can be used and evacuation when it is possible The route R can be displayed to provide useful information to residents.

  (F) In the above embodiment, evacuation is assumed when disasters such as earthquakes and floods occur and predictions are made. However, in the search for evacuation routes R when infections such as influenza occur and predictions are made. You may apply. That is, the above evacuation route search system can be applied when an abnormal situation including a disaster occurs or is predicted.

  Here, in the system applied to the abnormal situation of infectious disease occurrence, a thermography (detection means) for detecting the body surface temperature of the passerby is installed in the region X, and information on the body surface temperature of the passerby is managed by the management server 31. A configuration for outputting to may be adopted. In this case, similarly to the monitoring camera 34, a large number of thermographs are installed on the road in the region X so that the entire road in the region X is covered as a detection range. Then, the management server 31 searches the evacuation route R while avoiding a road on which a person having a body surface temperature equal to or higher than a predetermined value (for example, 38 degrees) passes during a disaster due to the occurrence of an infectious disease.

  A person with a high body surface temperature, that is, a high fever, is likely to have an infection. For this reason, if it avoids the road where the body surface temperature passed the predetermined value or more, the possibility that the virus possessed by the passer-by may be infected at the time of evacuation can be reduced.
