  Hereinafter, with reference to the drawings, embodiments of a missing person search support program, a missing person search support method, and an information processing apparatus according to the present invention will be described in detail.

(One example of the missing person search support method)
FIG. 1 is an explanatory view showing an example of a missing person search support method according to the embodiment. In FIG. 1, the information processing apparatus 101 is a computer that supports a search for a missing person. The information processing apparatus 101 may be, for example, a server, or may be a PC (Personal Computer), a smartphone, a tablet terminal, or the like.

  The missing person is, for example, an elderly person or a lost child who is lost due to a bribe. The elderly and children are at a loss of physical strength while being lost, and are debilitating, and there is a risk of life-threatening problems such as dehydration due to heat stroke, traffic accidents, and fractures due to falls. For this reason, it is important to detect and protect as soon as possible when it is found that the elderly and children have become missing.

  For example, as a measure against pressure sores, it is conceivable to attach a device having a GPS (Global Positioning System) tracking function to shoes such as elderly people with dementia. However, there are problems such as cost problems, breakdown of equipment, and not wearing shoes at the time of heeling, which is not a sufficient solution.

  In addition, it is possible to narrow the search range based on the elapsed time from the time when the missing is found, but it is better for searchers such as family members and care workers to search anywhere in the search range first It is difficult to judge For this reason, the search range is to be searched gradually, and searching for the missing person takes time and effort, and it may not be able to find and protect early.

  Therefore, in the present embodiment, a search for a missing person search support method will be described, which narrows the search range and makes it easy to determine a portion to be searched preferentially within the search range. Hereinafter, an example of the missing person search support processing of the information processing apparatus 101 will be described. Here, the case where elderly people with dementia etc. are missing due to a pressure sore will be described as an example.

  (1) The information processing apparatus 101 receives time information and position information. Here, the time information is information indicating the time when the missing state is found. For example, the time when a family member or a care worker noticed the missing, or the time when the user saw last before the missing was specified as the time when the missing became unknown.

  Further, the position information is information indicating the position where it has become missing. For example, the location of the missing person's home or the place where a family member or a care worker saw last before becoming missing is specified as the missing location. For example, the information processing apparatus 101 may receive time information and position information from an external computer, or may receive time information and position information directly input to the own apparatus by a user's operation input.

  Here, as the time information, the information indicating the time “10:00, May 1, 2015” at which the family and the care staff noticed that it was missing was accepted, and as the position information, the home of the missing person “ The case where the information indicating “Mr. ○ ○ home” is accepted will be described as an example.

  (2) The information processing apparatus 101 sets, for the position indicated by the received position information, a range corresponding to the elapsed time from the time indicated by the received time information. Here, the range is a movable range of the missing person estimated based on the elapsed time from the time when the missing becomes to the current time.

  Specifically, for example, the information processing apparatus 101 first calculates an elapsed time from the time indicated by the received time information to the current time. Next, the information processing apparatus 101 calculates the moving distance of the missing person by multiplying the calculated elapsed time by the average moving speed of the missing person. As the average moving speed, a predetermined moving speed set in advance, for example, an average moving speed of elderly people suffering from dementia (for example, 3 km / h) may be used.

  Then, the information processing apparatus 101 sets, for example, a circular range having the calculated movement distance as a radius centering on the position indicated by the received position information. Thereby, the range expanded according to the elapsed time from the time when it became unknown to the present time can be set as the movable range of the missing person.

  Here, assuming that the current time is "11:00 on May 1, 2015", the elapsed time is "one hour". Also, assuming that the average moving speed of the missing person is “3 km / h”, the moving distance is “3 km”. Therefore, a circular area having a radius of "3 km" is set around the home of the missing person.

  The shape of the range is not limited to a circle. For example, the shape of the range may be rectangular. In this case, for example, the movement distance of the missing person may be used as the distance from the position indicated by the position information to each vertex or the distance to each side.

  (3) When displaying information indicating the set range on the map, the information processing device 101 performs control to highlight a predetermined facility within the set range by referring to the facility information of the facility. Here, the facility information is, for example, information indicating the correspondence between the name of the facility and the position. The predetermined facility is, for example, a facility where a missing person such as a temple, a park, a hospital, or a friend's house is likely to stop by. In addition, the specified facility may be a facility that actively protects a prisoner-like person such as a police box, a police station, a fire station, a city office, a town office, a welfare institution for the elderly, etc.

  In the example of FIG. 1, the map 120 is displayed on the display screen 110. The map 120 is a diagram in which the area including the home of the missing person is reduced at a constant rate and represented on a plane using figures, symbols, and the like. The display screen 110 may be included in the information processing apparatus 101, or may be included in an external computer connected to the information processing apparatus 101.

  In the map 120, a balloon 121 indicates the position of the missing person at home. Further, on the map 120, a circular range 122 with a radius of "3 km" is displayed centering on the home of the missing person. A range 122 indicates the boundary of the range set in accordance with the elapsed time from the time of the missing, and indicates the movable range of the missing person.

  Further, in the map 120, the shrines, hospitals, and parks located within the range 122 are highlighted. Specifically, a balloon 123 indicating the position of “●● Shinto shrine” in the range 122 is displayed. In addition, a balloon 124 indicating the position of “◇ hospital” within the range 122 is displayed. Further, a balloon 125 indicating the position of “●● park” in the range 122 is displayed. In each of the balloons 123 to 125, a facility name is displayed.

  As described above, according to the information processing apparatus 101, it is possible to set a range corresponding to the elapsed time from the time of the missing state to the position of the missing state. Thereby, the range expanded according to the elapsed time from the missing time to the current time can be set as the movable range of the missing person.

  Further, according to the information processing apparatus 101, when displaying information indicating the set range on the map, control is performed to highlight a predetermined facility within the range with reference to the facility information of the facility. it can. In this way, the range where the missing person can move is displayed on the map, and when the facility that the missing person is likely to stop by and the person who is likely to see it included in the range are positively protected You can highlight the facilities that will

  For this reason, a searcher such as a family member or a care worker can narrow down the search range and can perform an efficient search by determining a portion to be searched preferentially within the search range. In the example of FIG. 1, the searcher can narrow down the search range within the range 122 on the map 120, and "● ● Shinto shrine", "◇ 病院 hospital", where missing persons are likely to drop in the range 122, We can search for "●● park" with priority and can lead to early detection of missing person, protection.

  In addition, two dotted-line circles displayed concentrically with the range 121 on the map 120 respectively indicate a range of radius “1 km” and a range of radius “2 km” centering on the home of the missing person. For example, the searcher can determine the approximate distance from the home of the missing person to each facility, using the two dotted circles displayed on the map 120 as a guide.

(System Configuration Example of Missing Person Search Support System 200)
Next, a system configuration example of the missing person search support system 200 according to the embodiment will be described. In the following description, a case where the information processing apparatus 101 shown in FIG. 1 is applied to the server 201 of the missing person search support system 200 will be described as an example.

(Stored contents of monitored person information DB 500)
Next, the storage contents of the monitored person information DB (database) 500 that the server 201 has will be described. The monitored person information DB 500 is realized by, for example, a storage device such as the memory 302 and the disk 305 shown in FIG.

  FIG. 5 is an explanatory diagram of an example of the storage content of the monitored person information DB 500. As shown in FIG. In FIG. 5, the monitored person information DB 500 has fields of monitored person ID, name, age, gender, address, and contact address, and by setting information in each field, monitored person information (for example, monitored person information Supervisor information 500-1, 500-2) is stored as a record.

  Here, the monitored person ID is an identifier for identifying the monitored person. A person to be monitored is a person to be monitored, and is, for example, an elderly person suffering from dementia. The name is the name of the person being monitored. The age is the age of the monitored person. The gender is the gender of the monitored person. The address is the address of the monitored person. The contact information is the name and telephone number of the contact information notifying the contact information regarding the monitored person. As the contact information, for example, the name and telephone number of the family of the monitored person are set.

(Memory content of landmark information DB 600)
Below, the memory content of landmark information DB600 which the server 201 has is demonstrated. The landmark information DB 600 is realized by, for example, a storage device such as the memory 302 and the disk 305.

  FIG. 6 is an explanatory view showing an example of the storage content of the landmark information DB 600. As shown in FIG. In FIG. 6, the landmark information DB 600 has fields of a monitored person ID, type, name, address, contact address, and induction rate, and by setting information in each field, landmark information (for example, a landmark) Information 600-1) is stored as a record.

  Here, the monitored person ID is an identifier for identifying the monitored person. The type is a type of landmark. The landmark is, for example, a facility such as a temple, a park, a hospital, a friend's house, etc. where a monitored person is likely to stop by. The name is the name of the landmark. The address is the address of the landmark. The contact is the landmark's phone number. The induction rate is a value indicating the degree to which the landmark guides the person to be monitored. Here, the higher the induction rate, the higher the degree to which the landmark guides the person to be monitored.

(Stored contents of road inclination information table 700)
Below, the memory content of the road inclination information table 700 which the server 201 has is demonstrated. The road inclination information table 700 is realized by, for example, a storage device such as the memory 302 and the disk 305.

  FIG. 7 is an explanatory view showing an example of the storage content of the road inclination information table 700. As shown in FIG. In FIG. 7, the road inclination information table 700 has fields of inclination level, speed variable and distance variable, and stores information on road inclination information 700-1 to 700-9 as records by setting information in each field. .

  The inclination level indicates the slope of the road, that is, the degree of inclination with respect to the horizontal plane. The slope level "1" indicates no slope (flat ground). A slope level of 2 or more indicates an upward slope (uphill slope), and indicates that the higher the slope level, the larger the upward slope. A slope level of -1 or less indicates a downslope (downslope), and the lower the slope level, the greater the downslope.

  Here, the traveling speed of the elderly when traveling on a sloped road tends to decrease as compared to traveling on a flat ground, regardless of whether it is an ascending slope or a descending slope. The speed variable indicates the degree of decrease in the moving speed of the elderly when moving on the road at each inclination level (unit:%). For example, the speed variable "30%" at the inclination level "4" indicates that the moving speed is reduced by 70% compared to when moving on a flat ground.

  Further, in the present embodiment, when estimating the “attainment position” described later, it is possible to regard the distance of the road at which the moving speed is reduced by a factor of x as a distance which is extended by a fraction of the actual distance. For example, it is considered that the distance of the road at which the traveling speed is reduced by 70% is a distance extended by 70% of the actual distance. The distance variable indicates the extension of the distance according to the degree of decrease of the moving speed corresponding to each inclination level (unit:%).

  Here, an example of calculation of the distance based on the distance variable will be described with reference to FIG.

  FIG. 8 is an explanatory view showing an example of calculation of the distance based on the distance variable. In FIG. 8, a section 801 indicates a road with a slope level “4”. The actual distance of the section 801 is "100 m". In the case of the inclination level “4”, the velocity variable is “30%” and the distance variable is “170%”. For this reason, assuming that the distance A of the section 801 is a distance extended by 70% of the actual distance "100 m", "distance A = actual distance x distance variable x 1/100 = 100 m x 1.7 = 170 m It becomes ".

(Contents stored in traffic volume and road width information table 900)
Next, the storage contents of the traffic volume and road width information table 900 that the server 201 has will be described. The traffic volume and road width information table 900 is realized by, for example, a storage device such as the memory 302 and the disk 305.

  FIG. 9 is an explanatory diagram of an example of the storage content of the traffic volume and road width information table 900. As shown in FIG. In FIG. 9, the traffic volume and road width information table 900 has fields of traffic volume level, road width level, speed variable, and distance variable, and information is set in each field to set traffic volume and road width information 900-1. Store 900-15 as a record.

  The traffic level indicates the traffic volume of the vehicle traveling on the road. The higher the traffic level, the higher the traffic volume. The road width level indicates the road width of the road. The higher the road width level, the wider the road is. Here, the traveling speed of the elderly tends to decrease as the traffic volume increases, and to decrease as the road width decreases.

  The speed variable indicates the degree of decrease in moving speed of the elderly when traveling on the road corresponding to the combination of traffic volume level and road width level (unit:%). For example, the speed variable "30%" corresponding to the combination of traffic level "5" and road width level "1" is 70% lower in travel speed than when traveling on a road with less traffic and wide road It is shown that. The distance variable indicates an extension of the distance according to the decrease in travel speed corresponding to the combination of traffic volume level and road width level (unit:%).

(Contents stored in weather and roof information table 1000)
Below, the memory content of the weather and roof information table 1000 which the server 201 has are demonstrated. The weather and roof information table 1000 is realized by, for example, a storage device such as the memory 302 and the disk 305.

  FIG. 10 is an explanatory view showing an example of the storage content of the weather / roof information table 1000. As shown in FIG. In FIG. 10, the weather and roof information table 1000 has fields of weather, roof, speed variable and distance variable, and records information on weather and roof information 1000-1 to 1000-6 by setting information in each field. Remember as.

  The weather indicates the weather such as rain, cloudy or sunny. The roof indicates whether the road has a roof for pedestrians to prevent rain, solar radiation, and the like. A roof "with" indicates a covered road, and a roof "without" indicates a roofless road. Here, the moving speed of the elderly at the time of rainy weather tends to be lower than that at the time of sunny or cloudy. However, if the road is covered, the degree of decrease in travel speed will be small.

  The speed variable indicates the degree of decrease in the moving speed of the elderly when moving on the road corresponding to the combination of the weather and the roof (unit:%). For example, the speed variable "20%" corresponding to the combination of the weather "rain" and the roof "none" indicates that the moving speed is reduced by 80% compared to when moving on a road when it is sunny or cloudy. There is. The distance variable indicates the extension of the distance according to the degree of decrease of the moving speed corresponding to the combination of the weather and the presence or absence of the roof (unit:%).

(Memory content of temperature information table 1100)
Below, the memory content of the air temperature information table 1100 which the server 201 has is demonstrated. The air temperature information table 1100 is realized by, for example, a storage device such as the memory 302 and the disk 305.

  FIG. 11 is an explanatory diagram of an example of the storage content of the air temperature information table 1100. In FIG. 11, the air temperature information table 1100 has fields of air temperature, speed variable, and distance variable, and stores the air temperature information 1100-1 to 1100-5 as a record by setting information in each field.

  Temperature indicates the temperature of the atmosphere (unit: degree). Here, when the temperature is high, such as on a summer day, or when the temperature is low, such as on a winter day, the moving speed of the elderly tends to be lower than when the temperature is comfortable (for example, 20 degrees). The speed variable indicates the degree of decrease in the moving speed of the elderly when moving on the road at each temperature (unit:%). For example, the speed variable "40%" at the temperature of "40 degrees" indicates that the moving speed is reduced by 60% as compared to the case of moving on the road at the time of comfortable temperature. The distance variable indicates an extension of the distance according to the degree of decrease of the moving speed corresponding to each air temperature (unit:%).

(Memory content of the streetlight information table 1200)
Below, the memory content of the street lamp information table 1200 which the server 201 has is demonstrated. The streetlight information table 1200 is realized by, for example, a storage device such as the memory 302 and the disk 305.

  FIG. 12 is an explanatory view showing an example of the storage content of the streetlight information table 1200. As shown in FIG. 12, the streetlight information table 1200 has fields of time zone, streetlight number level, speed variable and distance variable, and by setting information in each field, streetlight information (for example, streetlight information 1200-1 to 1200). -3) is stored as a record.

  The time zone is a time zone obtained by dividing one day into one hour. The number of lampposts indicates the number of lampposts provided on the road. The higher the level of streetlights, the greater the number of streetlights. Here, since the time zone from the evening to dawn is dark and difficult to walk, the moving speed of the elderly tends to decrease compared to other time zones. However, as the number of streetlights provided on the road increases, the degree of decrease in travel speed decreases.

  The speed variable indicates the degree of decrease in the moving speed of the elderly when moving on the road corresponding to the combination of the time zone and the number of street lights (unit:%).

(Example screen of missing person setting screen)
Next, a screen example of the missing person setting screen displayed on the display 406 of the client device 202 will be described. The missing person setting screen is displayed, for example, when the missing person search support application is activated on the client device 202.

  FIG. 20 is an explanatory view showing an example of a missing person setting screen. In FIG. 20, the missing person setting screen 2000 is an operation screen for setting the missing person. In the missing person setting screen 2000, for example, when the box 2001 is selected by the user's operation input using the input device 407 shown in FIG. 4, the name of the missing person can be input.

  When box 2002 is selected on the missing person setting screen 2000, the age of the missing person can be input. When box 2003 is selected on the missing person setting screen 2000, the missing time can be input. As the missing time, for example, a time when a family member or a care worker notices that the monitored person is missing, or a time when the monitored person was last seen before becoming missing is input. Ru.

  When the box 2004 is selected on the missing person setting screen 2000, information indicating a missing place can be input. The missing place may be designated by designating one point on the map. As the missing place, for example, information indicating the home of the person to be monitored or a place where a family member or a care worker finally saw the person to be monitored before it becomes missing is input. If boxes 2005 and 2006 are selected on the missing person setting screen 2000, it is possible to input the contact information (name of the contact person, telephone number) of the missing person.

  When the search button 2007 is selected with the name input in the box 2001 on the missing person setting screen 2000, the age, address, and contact information of the missing person corresponding to the input name is the box 2002, It is automatically input in 2004-2006.

(Example of functional configuration of server 201)
FIG. 21 is a block diagram showing a functional configuration example of the server 201. As shown in FIG. In FIG. 21, the server 201 includes an accepting unit 2101, a setting unit 2102, a display control unit 2103, a searching unit 2104, and an estimating unit 2105. The reception unit 2101 to the estimation unit 2105 are functions as a control unit, and more specifically, for example, by causing the CPU 301 to execute a program stored in a storage device such as the memory 302 or the disk 305 illustrated in FIG. Alternatively, the function is realized by the I / F 303. The processing result of each functional unit is stored, for example, in a storage device such as the memory 302 or the disk 305.

  The receiving unit 2101 receives time information and position information. Here, the time information is information indicating the time when the monitored person went missing (lost time). Further, the position information is information indicating a position (lost place) where the monitored person is lost. Specifically, for example, the receiving unit 2101 receives time-of-day information and position information by receiving missing person information from the client device 202.

  The setting unit 2102 sets a range corresponding to an elapsed time T from the time indicated by the received time information, for the position indicated by the received position information. Here, the range is a range where the monitored person can move, which is estimated from the elapsed time T from the missing time to the current time and the average moving speed V of the monitored person.

  As the average moving speed V of the person to be monitored, a predetermined moving speed set in advance, for example, an average moving speed (for example, 3 km / h) of elderly people suffering from dementia may be used. In addition, the setting unit 2102 may select the average moving speed V of the monitored person from among the plurality of speed candidates.

  For example, the average moving speed of the elderly may vary depending on the age and gender. Therefore, the setting unit 2102 selects the moving speed corresponding to the age and gender of the person to be monitored as the average moving speed V with reference to, for example, the information indicating the correspondence between the age, the sex, and the moving speed. May be

  Also, the average moving speed of the elderly may vary depending on the weather. For example, the moving speed at the time of rainy weather tends to be lower than at the time of sunny or cloudy. Therefore, the setting unit 2102 may select the moving speed corresponding to the weather of the missing place as the average moving speed V, for example, with reference to the information indicating the correspondence between the weather and the moving speed.

  In addition, the server 201 can specify the weather in the vicinity of the missing place by, for example, accessing the server providing the weather forecast service and acquiring the weather information.

  Specifically, for example, first, the setting unit 2102 calculates an elapsed time T from the time indicated by the received time information to the current time. Next, the setting unit 2102 calculates the movement distance D of the person to be monitored by multiplying the calculated elapsed time T by the average movement speed V of the person to be monitored. Then, the setting unit 2102 sets, for example, a circular range having the calculated movement distance D as a radius centering on the position indicated by the received position information.

  Thereby, the range expanded according to elapsed time T from the missing time to the current time can be set as the movable range of the monitored person. In the following description, as a range set according to the elapsed time T, a circular range having the moving distance D as a radius will be described as an example. In addition, a circular range having a radius of movement distance D may be described as an “approximately circle”.

  When displaying the information indicating the set approximate circle on the map, the display control unit 2103 performs control to highlight a predetermined facility included in the approximate circle with reference to the facility information of the facility. Here, the information indicating the approximate circle may be, for example, line information indicating the boundary of the approximate circle by a solid line or a dotted line, and even if it is graphic information indicating the approximate circle with a background color different from other areas. Good.

  The predetermined facility is, for example, a facility where a monitored person, such as a temple, a park, a hospital, or a friend's house is likely to stop by. In addition, the specified facility may be a facility that actively protects a prisoner-like person such as a police box, a police station, a fire station, a city office, a town office, a welfare institution for the elderly, etc.

  Specifically, for example, the display control unit 2103 first acquires map data of the display area. The display area is an area of a predetermined range including a missing place on the map, and is set, for example, in a range of several kilometers to several tens of kilometers around the missing place. The map data of the display area may be acquired from the map information DB 1900 shown in FIG. 19 or may be acquired from an external map server.

  Next, the display control unit 2103 refers to the landmark information DB 600 shown in FIG. 6, and among the landmarks corresponding to the monitored person ID of the monitored person, the lands whose address is included in the set approximate circle Identify the mark. Further, the display control unit 2103 refers to the police box etc. information table 1500 to specify facilities such as police box where the address is included in the set approximate circle.

  Next, based on the map data of the display area, the display control unit 2103 generates screen information of a facility map in which facilities such as landmarks and alternations included in the approximate circle on the map are highlighted and displayed. More specifically, for example, the display control unit 2103 displays an icon capable of identifying the type of the facility, or balloon-displays the facility name of the facility, in association with the position of the facility such as a landmark or police box. It is also possible to generate screen information of the facility map to be

  Then, the display control unit 2103 causes the display 406 of the client device 202 to display the facility map by transmitting the screen information of the generated facility map to the client device 202. More specifically, for example, the display control unit 2103 may transmit screen information of the facility map to the client device 202 in response to receiving a map display request of the facility map from the client device 202.

  As a result, the range (approximate circle) where the monitored person can move is displayed on the map, and when the facility that the monitored person is likely to stop by and the person who is likely to be dropped out are included You can highlight the facilities that will protect you. Note that a display example of the facility map will be described later with reference to FIG.

  In addition, the display control unit 2103 acquires weather information, and when the acquired weather information indicates rainy weather, refers to the roof information of the road to highlight the covered road included in the set approximate circle. Control may be performed. Specifically, for example, the display control unit 2103 first extracts the section information of the section included in the approximate circle on the map from the map information DB 1900 shown in FIG. Then, the display control unit 2103 specifies the section of the roof level “1” with reference to the roof level of the extracted section information.

  Next, based on the map data of the display area, the display control unit 2103 generates screen information of a roof map that highlights and displays a section of roof level “1” included in the approximate circle on the map. More specifically, for example, the display control unit 2103 may generate screen information of a roof map in which the section of the roof level “1” is displayed in a color different from that of the other sections.

  Then, the display control unit 2103 displays the roof map by transmitting the screen information of the generated roof map to the client device 202. More specifically, for example, the display control unit 2103 may transmit the screen information of the roof map to the client device 202 in response to receiving the map display request of the roof map from the client device 202.

  Thus, it is possible to display the range (approximate circle) in which the person to be monitored can move on the map, and highlight the covered road (section) included in the range. In addition, the display example of a roof map is later mentioned using FIG.

  Further, the display control unit 2103 may perform control of highlighting a steep road included in the set approximate circle by referring to the road inclination information. Specifically, for example, the display control unit 2103 first specifies the section of the specific inclination level with reference to the inclination level of the section information of the section included in the approximate circle. The specific inclination level can be set arbitrarily, and is set to, for example, an inclination level such as “3 or more” or “−3 or less”.

  Next, based on the map data of the display area, the display control unit 2103 generates screen information of a road inclination map in which a section of a specific inclination level included in the approximate circle on the map is emphasized and displayed. More specifically, for example, the display control unit 2103 may generate screen information of a road inclination map in which a section of a specific inclination level is displayed in a color different from that of the other sections.

  Then, the display control unit 2103 displays the road inclination map by transmitting the screen information of the generated road inclination map to the client device 202. More specifically, for example, the display control unit 2103 transmits the screen information of the road inclination map to the client device 202 in response to receiving the map display request of the road inclination map from the client device 202. Good.

  Further, the display control unit 2103 may perform control to highlight the road on which the stairs included in the set approximate circle exist by referring to the stairs information of the road. Specifically, for example, the display control unit 2103 first specifies a section at a specific step level with reference to the step level of the section information of the section included in the approximate circle. The specific stair level can be arbitrarily set, for example, set to the stair level such as “two or more”.

  Next, the display control unit 2103 generates, based on the map data of the display area, screen information of a stairs map in which a section of a particular stairs level included in the approximate circle on the map is emphasized and displayed. More specifically, for example, the display control unit 2103 may generate screen information of a stair map in which a section of a particular stair level is displayed in a color different from that of the other sections.

  Then, the display control unit 2103 transmits the screen information of the generated stairs map to the client device 202, thereby displaying the stairs map. More specifically, for example, the display control unit 2103 may transmit the screen information of the stairs map to the client device 202 in response to receiving the map display request of the stairs map from the client device 202.

  Thus, it is possible to display the range (approximate circle) in which the person to be monitored can move on the map, and to highlight the road (section) on which the stairs are included included in the range. In addition, the example of a display of a stairs map is later mentioned using FIG.

  Further, the display control unit 2103 may perform control to highlight a road having a large traffic volume included in the set approximate circle by referring to the traffic volume information of the road. Specifically, for example, the display control unit 2103 first specifies a section at a specific traffic level with reference to the traffic level of the section information of the section included in the approximate circle.

At this time, the display control unit 2103 may specify a section of a specific traffic volume level and a specific road width level in consideration of the road width level. The specific road width level can be arbitrarily set, for example, set to a road width level such as “1”.

  Next, based on the map data of the display area, the display control unit 2103 generates screen information of a traffic volume map in which a section of a specific traffic volume level included in the approximate circle on the map is emphasized and displayed. More specifically, for example, the display control unit 2103 may generate screen information of a traffic volume map in which a section of a specific traffic volume level is displayed in a color different from that of the other sections.

  Then, the display control unit 2103 transmits the screen information of the generated traffic map to the client device 202 to display the traffic map. More specifically, for example, the display control unit 2103 may transmit screen information of the traffic map to the client device 202 in response to receiving the map display request of the traffic map from the client device 202. Good.

  Thus, it is possible to display the range (approximate circle) in which the person to be monitored can move on the map, and to highlight the roads (sections) with high traffic included in the range. A display example of the traffic volume map will be described later with reference to FIG.

  In addition, when the current time is included in a predetermined time zone, the display control unit 2103 performs control to highlight the road with many street lights included in the set approximate circle by referring to the street light information of the road. You may The predetermined time zone can be set arbitrarily, and is set to, for example, a time zone from 0 o'clock to 5 o'clock or a time zone from 17 o'clock to 23 o'clock.

  Specifically, for example, the display control unit 2103 first specifies the section with the specific number of streetlights level by referring to the level with the number of streetlights of the section information of the section included in the approximate circle. The specific streetlight number level can be arbitrarily set, and for example, is set to the streetlight number level such as “3 or more”.

  The search unit 2104 refers to the facility information of the facility and searches for a route from the position indicated by the received position information to any one of the facilities. Specifically, for example, first, the search unit 2104 specifies a landmark having a high induction rate among landmarks corresponding to the monitored person ID of the monitored person with reference to the landmark information DB 600. At this time, the search unit 2104 may specify a landmark having a high inductivity existing in the display area.

  Here, a landmark with a high induction rate may be, for example, a landmark with the highest induction rate, or may be a landmark with a induction rate equal to or higher than a threshold (for example, 50%). Furthermore, the landmarks with high induction rates may be a plurality of high-order landmarks with high induction rates.

  Next, the searching unit 2104 sets the specified landmark as a destination, and searches for a route from the position indicated by the received position information to the destination. At this time, for example, the search unit 2104 may search for a route with the shortest distance to the destination. Also, the search unit 2104 may search for a route with the smallest cumulative value such as the slope level and traffic volume level of each section on the route to the destination.

  The search unit 2104 may set a landmark selected by the user's operation input as a destination, and search for a route from the position indicated by the received position information to the destination. The selection of the landmark to be the destination is performed, for example, on a map screen 3200 shown in FIG. 32 described later.

  The estimation unit 2105 estimates an arrival position when moving at a predetermined moving speed on the searched route based on the elapsed time T from the time indicated by the received time information. Specifically, for example, the estimation unit 2105 may estimate a position moved by the movement distance D (elapsed time T × average movement velocity V) on the searched route as the arrival position. However, if the total distance L of the route is shorter than the movement distance D, the destination is estimated as the arrival position.

  In addition, as described above, the traveling speed of the elderly when traveling on a sloped road tends to decrease as compared with traveling on a flat ground, regardless of whether it is an ascending slope or a descending slope. Therefore, the estimation unit 2105 may estimate the arrival position based on the slope (slope level) of each section on the searched route with reference to the slope information of the road.

  Specifically, for example, first, the estimation unit 2105 extracts section information of each section on the searched route from the map information DB 1900, and specifies the inclination level of each section. Next, the estimation unit 2105 specifies, for example, the distance variable corresponding to the inclination level of each of the identified sections with reference to the road inclination information table 700 shown in FIG. 7.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the inclination level of each section specified and the actual distance of each section. The actual distance of each section can be determined from the start point coordinates and the end point coordinates of each section. Next, the estimation unit 2105 calculates the total distance L of the route by accumulating the calculated distances of the sections.

  Then, the estimation unit 2105 may estimate a position moved by the movement distance D on the route of the calculated total distance L as the arrival position. In this way, it is possible to estimate the reached position when moving at the average moving velocity V on the route, in consideration of the slope (tilt level) of each section on the route.

  Here, with reference to FIG. 22, an example of estimation of the reached position in consideration of the slope (tilt level) of each section on the route will be described.

  FIG. 22 is an explanatory view showing an example of estimation of the reached position. In FIG. 22, a route 2200 is a route from the departure place “Mr. ○ ○ 's house” to the destination “●● park”. “Mr. ○○ 's home” is a position (lost place) where the monitored person is missing.

  The route 2200 includes an interval 2201, an interval 2202, and an interval 2203. Here, the actual distances of the sections 2201 to 2203 are respectively set to "1000 m". Further, the inclination level of the section 2201 is “1”, the inclination level of the section 2202 is “4”, and the inclination level of the section 2203 is “5”.

  In this case, the estimation unit 2105 refers to the road inclination information table 700 to identify the distance variable corresponding to the inclination level of each of the sections 2201 to 2203. Then, the estimation unit 2105 calculates the distance of each of the sections 2201 to 2203 based on the distance variable corresponding to the inclination level of each of the sections 2201 to 2203 and the actual distance of each of the sections.

  Here, the distance variable of the section 2201 is “100%”. Therefore, the distance of the section 2201 is “1000 m (= 1000 m × 100 × 1/100)”. Also, the distance variable of the section 2202 is “170%”. Therefore, the distance of the section 2202 is “1700 m (= 1000 m × 170 × 1/100)”. Further, the distance variable of the section 2203 is "195%". Therefore, the distance of the section 2203 is “1950 m (= 1000 m × 195 × 1/100)”.

  Next, the estimating unit 2105 calculates the total distance L of the route 2200 by accumulating the calculated distances of the sections 2201 to 2203. Here, the total distance L of the route 2200 is “4650 m”. Then, the estimation unit 2105 estimates the position moved by the movement distance D on the route 2200 of the calculated total distance L “4650 m” as the arrival position.

  Here, assuming that the average moving speed V is “3 km / h” and the elapsed time T is “1 h”, the moving distance D is “3 km”. For this reason, the arrival position is a position moved by a movement distance D “3000 m” on the route 2200 of the total distance L “4650 m”. That is, the arrival position is a position 2204 in which the section 2203 of the distance "1950 m" is moved by "300 m".

  Returning to the description of FIG. 21, as described above, the traveling speed of the elderly tends to decrease as the traffic volume increases, and to decrease as the road width decreases. For this reason, the estimation unit 2105 estimates the arrival position based on the traffic volume (traffic volume level, road width level) of each section on the searched route by referring to the traffic volume information of the road. Good.

  Specifically, for example, the estimation unit 2105 first specifies the traffic volume level and the road width level of each section with reference to the section information of each section on the searched route. Next, the estimation unit 2105 specifies, for example, with reference to the traffic volume and road width information table 900 shown in FIG. 9, the distance variable corresponding to the combination of the traffic volume level and the road width level of each identified section.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the traffic volume level and the road width level of each section specified, and the actual distance of each section. Next, the estimation unit 2105 calculates the total distance L of the route by accumulating the calculated distances of the sections. Then, the estimation unit 2105 estimates a position moved by the movement distance D on the route of the calculated total distance L as the arrival position.

  In this way, it is possible to estimate the arrival position when moving at the average travel speed V on the route in consideration of the traffic volume (traffic volume level, road width level) of each section on the route.

  Further, as described above, the moving speed of the elderly at the time of rainy weather tends to be lower than that at the time of sunny or cloudy. However, if the road is covered, the degree of decrease in travel speed will be small. For this reason, when the estimation unit 2105 acquires weather information and the acquired weather information indicates rainy weather, it refers to the roof information of the road and determines whether each section on the searched route is covered or not The arrival position may be estimated on the basis of

  Specifically, for example, the estimating unit 2105 first specifies the roof level of each section with reference to the section information of each section on the searched route. Next, the estimation unit 2105 specifies, for example, the distance variable corresponding to the roof level of each of the specified sections with reference to the weather / roof information table 1000 shown in FIG.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the roof level of each specified section and the actual distance of each section. Next, the estimation unit 2105 calculates the total distance L of the route by accumulating the calculated distances of the sections. Then, the estimation unit 2105 estimates a position moved by the movement distance D on the route of the calculated total distance L as the arrival position.

  In this way, it is possible to estimate the reached position when moving at the average moving speed V on the route, considering whether each section on the route is covered or not.

  In addition, as described above, the moving speed of the elderly when the temperature is high or low, such as summer day or winter day, tends to be lower than that when the temperature is comfortable (for example, 20 degrees). Therefore, the estimation unit 2105 may acquire the temperature information, and the acquired temperature information may estimate the reached position based on the temperature. The temperature information can be acquired, for example, by accessing a server providing a weather forecast service.

  Specifically, for example, the estimation unit 2105 first acquires temperature information indicating the temperature of the time zone including the missing time. Next, the estimation unit 2105 specifies, for example, the distance variable corresponding to the air temperature indicated by the acquired air temperature information with reference to the air temperature information table 1100 illustrated in FIG.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the specified air temperature and the actual distance of each section. Next, the estimation unit 2105 calculates the total distance L of the route by accumulating the calculated distances of the sections. Then, the estimation unit 2105 estimates a position moved by the movement distance D on the route of the calculated total distance L as the arrival position.

  Thereby, in consideration of the temperature on the day, it is possible to estimate the reached position when moving at the average moving speed V on the route.

  Further, as described above, since the time zone from the evening to the dawn is dark and difficult to walk, the moving speed of the elderly tends to decrease compared to other time zones. However, as the number of streetlights provided on the road increases, the degree of decrease in travel speed decreases. For this reason, when the current time is included in a predetermined time zone, the estimation unit 2105 refers to the streetlight information of the road, and based on the number of streetlights present in each section on the searched route, the reaching position You may decide to estimate The predetermined time zone can be set arbitrarily, and is set to, for example, a time zone from 0 o'clock to 5 o'clock or a time zone from 17 o'clock to 23 o'clock.

  Specifically, for example, the estimation unit 2105 first specifies the number of lampposts of each section with reference to the section information of each section on the searched route. Next, the estimation unit 2105 specifies, for example, the distance variable corresponding to the level number of the streetlights of each identified section with reference to the streetlight information table 1200 shown in FIG. 12.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the number of level lights of each section specified and the actual distance of each section. Next, the estimation unit 2105 calculates the total distance L of the route by accumulating the calculated distances of the sections. Then, the estimation unit 2105 estimates a position moved by the movement distance D on the route of the calculated total distance L as the arrival position.

  Thereby, in the time zone where the missing time is dark and difficult to walk, the arrival position when moving at the average moving speed V on the route is estimated in consideration of the number of streetlights present in each section on the route. be able to.

  In addition, as described above, the moving speed of the elderly when moving on a road with stairs tends to be lower than that when moving on a road without stairs. For this reason, the estimation unit 2105 may estimate the arrival position based on the length of the stairs present in each section on the searched route, with reference to the stairs information of the road.

  Specifically, for example, the estimating unit 2105 first specifies the step level of each section with reference to the section information of each section on the searched route. Next, the estimation unit 2105 specifies, for example, the distance variable corresponding to the step level of each of the specified sections with reference to the step information table 1300 shown in FIG.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the step level of each of the specified sections and the actual distance of each section. Next, the estimation unit 2105 calculates the total distance L of the route by accumulating the calculated distances of the sections. Then, the estimation unit 2105 estimates a position moved by the movement distance D on the route of the calculated total distance L as the arrival position.

  In this way, it is possible to estimate the arrival position when moving at the average moving velocity V on the route, taking into consideration the length of the stairs present in each section on the route.

  Further, as described above, the moving speed of the elderly when moving on a road with many passersby tends to be lower than that in the case of moving on a road with few passers. Therefore, the estimation unit 2105 may estimate the reaching position based on the amount of people passing each section on the searched route with reference to the passerby information of the road.

  Specifically, for example, first, the estimation unit 2105 specifies the passer level of each section with reference to the section information of each section on the searched route. Next, the estimation unit 2105 specifies, for example, the distance variable corresponding to the passer level of each of the identified sections with reference to the passer information table 1400 shown in FIG.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the passer level of each specified section and the actual distance of each section. Next, the estimation unit 2105 calculates the total distance L of the route by accumulating the calculated distances of the sections. Then, the estimation unit 2105 estimates a position moved by the movement distance D on the route of the calculated total distance L as the arrival position.

  In this way, it is possible to estimate the arrival position when moving at the average moving speed V on the route, taking into consideration the amount of people passing each section on the route.

  The arrival position may be estimated in consideration of a plurality of factors such as the slope of each section on the route, traffic volume, the presence or absence of a roof, the number of streetlights, the length of stairs, passersby, and temperature. In this case, the estimation unit 2105 calculates the distance of each section based on, for example, the maximum distance variable among the distance variables of a plurality of elements and the actual distance of each section.

  In addition, the display control unit 2103 may perform control to display information indicating the estimated arrival position on the map along with the searched route. Specifically, for example, the display control unit 2103 displays, on the map, the route (moving route) to the estimated arrival position along with the searched route (searching route) based on the map data of the display area. Generate screen information of the search route map. More specifically, for example, the display control unit 2103 may generate screen information of a search route map that displays the movement route in a display format different from the search route.

  Then, the display control unit 2103 transmits the screen information of the generated search route map to the client device 202 to display the search route map. More specifically, for example, the display control unit 2103 may transmit screen information of the search route map to the client device 202 in response to receiving a map display request of the search route map from the client device 202. Good.

  Thus, for example, along with a search route to a facility having a high degree of guiding a person to be monitored, a moving route to a position where the person to be monitored is estimated to be moving by the current time may be displayed on a map. it can. A display example of the search route map will be described later with reference to FIG.

(The missing person search support processing procedure of server 201)
Next, the missing person search support processing procedure of the server 201 will be described.

  FIG. 35 is a flow chart showing an example of the missing person search support processing procedure of the server 201. In the flowchart of FIG. 35, first, the server 201 determines whether missing person information has been received from the client device 202 (step S3501).

  Here, the server 201 waits to receive missing person information (step S3501: No). When the server 201 receives missing person information (step S3501: YES), the server 201 executes map generation processing (step S3502). Note that a specific processing procedure of the map generation processing will be described later with reference to FIGS. 36 to 38.

  Next, the server 201 performs control to display the facility map on the display 406 of the client device 202 (step S3503). Then, the server 201 determines whether a map display request has been received from the client device 202 (step S3504).

  Here, if the map display request has not been received (step S3504: NO), the server 201 proceeds to step S3506. On the other hand, if the map display request has been received (step S3504: YES), the server 201 performs control to display the map corresponding to the received map display request on the display 406 of the client apparatus 202 (step S3505).

  Next, the server 201 determines whether the destination has been changed on the search route map (step S3506). Here, if the destination has not been changed (step S3506: NO), the server 201 proceeds to step S3509.

  On the other hand, if the destination has been changed (step S3506: YES), the server 201 executes a search route map generation process (step S3507). The specific processing procedure of the search route map generation processing is the same as steps S3808 to S3811 shown in FIG. 38 described later, and thus the illustration and description thereof will be omitted.

  Next, the server 201 performs control to display the search route map on the display 406 of the client device 202 (step S3508). Then, the server 201 determines whether an end instruction for ending the display of the map screen has been received from the client device 202 (step S3509).

  Here, if the end instruction has not been received (step S3509: NO), the server 201 returns to step S3504. On the other hand, if the end instruction has been received (step S3509: YES), the server 201 ends the series of processing according to this flowchart.

  In this way, various map screens that support search for the missing person can be displayed on the display 406 of the client device 202.

  Next, a specific processing procedure of the map generation processing of step S3502 shown in FIG. 35 will be described.

  36 to 38 are flowcharts showing an example of a specific processing procedure of the map generation processing. In the flowchart of FIG. 36, first, the server 201 calculates an elapsed time T from the time (lost time) indicated by the received missing person information to the current time (step S3601).

  Next, the server 201 calculates the movement distance D of the person to be monitored by multiplying the calculated elapsed time T by the average movement speed V of the person to be monitored (step S3602). Then, the server 201 sets a circular approximate circle whose radius is the calculated movement distance D, centering on the position (the missing place) indicated by the received missing person information (step S3603).

  Next, the server 201 acquires map data of the display area (step S3604). Then, the server 201 refers to the landmark information DB 600 to specify the landmarks included in the set approximate circle (step S3605). At this time, the server 201 may specify the facility such as the police box included in the set approximate circle by referring to the police box information table 1500.

  Next, the server 201 generates screen information of a facility map in which landmarks included in the approximate circle on the map are emphasized and displayed based on the acquired map data of the display area (step S3606). In this way, it is possible to generate a facility map that highlights facilities that the monitored person is likely to drop in, which is included in the movable range (approximate circle) where the monitored person can move.

  Next, the server 201 specifies the section of the specific inclination level with reference to the inclination level of the section information of the section included in the approximate circle on the map (step S3607). Then, based on the map data of the display area, the server 201 generates screen information of a road inclination map which emphasizes and displays a section of a specific inclination level included in the approximate circle on the map (step S3608).

  Thus, it is possible to generate a road inclination map that highlights steep roads (sections) included in the range (approximate circle) in which the person to be monitored can move.

  Next, the server 201 refers to the traffic volume level of the segment information of the segment included in the approximate circle on the map, and identifies the segment of the specific traffic volume level (step S3609). At this time, the server 201 may specify a section of a specific traffic volume level and a specific road width level, also in consideration of the road width level. Then, based on the map data of the display area, the server 201 generates screen information of a traffic volume map to highlight and display a section of a specific traffic volume level included in the approximate circle on the map (step S3610). The process shifts to step S3701 shown in FIG.

  In this way, it is possible to generate a traffic volume map that highlights roads (sections) with high traffic volumes included in the range (approximate circle) in which the monitored person can move.

  In the flowchart of FIG. 37, first, the server 201 acquires weather information (step S3701). Then, the server 201 determines whether the acquired weather information indicates rainy weather (step S3702). Here, when it does not indicate rainy weather (step S3702: No), the server 201 proceeds to step S3705.

  On the other hand, if it indicates rainy weather (step S3702: YES), the server 201 refers to the roof level of the section information of the section included in the approximate circle on the map, and identifies the section of the roof level "1" (step S3703). ). Then, based on the map data of the display area, the server 201 generates screen information of a roof map that highlights and displays the section of roof level “1” included in the approximate circle on the map (step S3704).

  Thus, it is possible to generate a roof map that highlights the covered roads (sections) included in the range (approximate circle) where the monitored person can move.

  Next, the server 201 determines whether the current time is included in a predetermined time zone (step S3705). Here, when it is not included in the predetermined time zone (step S3705: No), the server 201 proceeds to step S3707.

  On the other hand, when it is included in the predetermined time zone (step S3705: Yes), the server 201 refers to the number of streetlights level of the section information of the section included in the approximate circle on the map and It identifies (step S3706). Then, based on the map data of the display area, the server 201 generates screen information of a streetlight map that emphasizes and displays a section of the specific streetlight number level included in the approximate circle on the map (step S3707).

  In this way, it is possible to generate a streetlight map that highlights roads (sections) with many streetlights or roads (sections) with few streetlights that are included in the range (approximate circle) in which the monitored person can move.

  Next, the server 201 refers to the step level of the section information of the section included in the approximate circle on the map, and identifies the section of the specific step level (step S3708). Then, based on the map data of the display area, the server 201 generates screen information of a stair map for emphasizing and displaying a section of a particular stair level included in the approximate circle on the map (step S3709). The process moves to step S3801 shown in FIG.

  A stairs map can be generated that highlights roads (sections) on which stairs are present, which are included in the range (approximate circle) where the monitored person can move.

  In the flowchart of FIG. 38, first, the server 201 specifies a specific passer level section with reference to the passer level of the section information of the section included in the approximate circle on the map (step S3801). Then, based on the map data of the display area, the server 201 generates screen information of a passer map for emphasizing and displaying a section of the specific passer level included in the approximate circle on the map (step S3802).

  In this way, it is possible to generate a passerby map that highlights roads (sections) with a large number of passers, which are included in the range (approximate circle) in which the monitored person can move.

  Next, the server 201 refers to the bus information table 1600 to identify the bus stop included in the approximate circle on the map (step S3803). Then, based on the map data of the display area, the server 201 generates screen information of a bus stop map to be displayed by highlighting bus stops included in the approximate circle on the map (step S3804).

  As a result, it is possible to generate a bus stop map highlighting the bus stops included in the range (approximate circle) in which the monitored person can move.

  Next, the server 201 refers to the care staff position information table 1800 to specify the position of the care staff present in the display area (step S3805). Then, the server 201 generates screen information of a care staff map indicating the position of the specified care staff based on the map data of the display area (step S3806).

  Thus, it is possible to generate a care staff map that displays information indicating the current position of the care staff present in the display area on the map.

  Next, the server 201 refers to the landmark information DB 600 to identify the landmark having the largest inductive ratio in the display area (step S3807). Then, the server 201 sets the specified landmark as a destination (step S3808), and searches for a route from the position (lost place) indicated by the missing person information (step S3809).

  Next, based on the elapsed time T, the server 201 estimates the arrival position when moving at the average moving speed V on the searched route (step S3810). At this time, the server 201 estimates the arrival position in consideration of, for example, the slope of each section on the route, traffic volume, the presence or absence of a roof, the number of streetlights, the length of stairs, passersby, air temperature, and the like.

  Then, based on the map data of the display area, the server 201 generates screen information of a search route map that displays the route (moving route) to the estimated arrival position on the map together with the searched route (search route). Then (step S3811), the process returns to the step that called the map generation process.

  In this way, a search route map is displayed that displays a movement route to a position where it is estimated that the person to be monitored is moving by the current time, as well as a search route to a facility with a high degree of guiding the person to be monitored Can.

  As described above, according to the server 201 according to the embodiment, a range (for example, an approximate circle) corresponding to the elapsed time T from the time of missing is set for the position of missing can do. Thereby, the range expanded according to elapsed time T from the missing time to the current time can be set as the movable range of the monitored person.

  Further, according to the server 201, when displaying information indicating the set range on the map, control can be performed to highlight a predetermined facility within the range with reference to the facility information of the facility. For example, facilities where people to be monitored such as temples, parks, hospitals, and friend's houses are likely to drop in, prescribed police stations, police stations, fire stations, city halls, town halls, welfare facilities for the elderly, etc. It is a facility that actively protects when you see it.

  As a result, the range (approximate circle) where the monitored person can move is displayed on the map, and when the facility that the monitored person is likely to stop by and the person who is likely to be dropped out are included You can highlight the facilities that will protect you.

  Further, according to the server 201, it is possible to set a range according to the elapsed time T from the time when the missing becomes based on the moving speed selected from the predetermined moving speed or the plurality of speed candidates. .
