  DESCRIPTION OF EMBODIMENTS 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 below in detail with reference to the drawings.

(One example of missing person search support method)
FIG. 1 is an explanatory diagram of an example of the missing person search support method according to the embodiment. In FIG. 1, an information processing apparatus 101 is a computer that supports searching for missing persons. The information processing apparatus 101 may be, for example, a server, 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 has gone missing due to a trap. Elderly people and children have life-threatening risks such as exhaustion and weakness while they are lost, 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 turns out that an elderly person or a child is missing.

  For example, as a measure against wrinkles, 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, equipment failures, and the need to wear shoes in the rain, and this 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 was found, but searchers such as family members and caregivers should preferentially search within the search range. It is difficult to judge. For this reason, the search range is searched randomly, and it still takes time and effort to search for the missing person, and it may not be possible to detect and protect early.

  Therefore, in the present embodiment, a missing person search support method that narrows down the search range and makes it easy to determine a place to search preferentially within the search range will be described. Hereinafter, a missing person search support processing example of the information processing apparatus 101 will be described. Here, a case where an elderly person with dementia or the like is missing due to a hemorrhoid 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 at which the information is missing. As the time of missing, for example, the time when a family member or care worker noticed that he was missing, the time when he / she finally found before missing, etc. are designated.

  Further, the position information is information indicating a position that has been lost. For example, the location of the missing person is designated as the home of the missing person or the place where the family or the care worker last seen before missing. 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 through a user operation input.

  Here, as time information, information indicating a time “10:00 on May 1, 2015” that a family member or a care worker notices that the person has been missing is received, and the home of the missing person “ An example will be described in which information indicating “Mr. XX's home” is received.

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

  Specifically, for example, first, the information processing apparatus 101 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 and 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 (for example, 3 km / h) of an elderly person suffering from dementia may be used.

  Then, the information processing apparatus 101 sets, for example, a circular range with the calculated moving distance as the radius around the position indicated by the received position information. 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.

  Here, if the current time is “May 1, 2015 11:00”, the elapsed time is “1 hour”. If the average moving speed of the missing person is “3 km / h”, the moving distance is “3 km”. For this reason, 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 a rectangle. In this case, for example, the moving 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 the information indicating the set range is displayed on the map, the information processing apparatus 101 performs control for highlighting a predetermined facility within the set range with reference to the facility information of the facility. Here, the facility information is information indicating a correspondence relationship between the name and position of the facility, for example. 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 predetermined facility may be a facility that actively protects a person who appears to be a deaf person, such as a police box, police station, fire department, city hall, town hall, welfare facility for the elderly.

  In the example of FIG. 1, a 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 certain 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's home. In addition, the map 120 displays a circular range 122 having a radius of “3 km” centered on the home of the missing person. The range 122 shows the boundary line of the range set according to the elapsed time from the time when it was missing, and shows the range in which the missing person can move.

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

  As described above, according to the information processing apparatus 101, a range corresponding to the elapsed time from the time of missing can be set for the position of missing. Thereby, the range expanded according to the elapsed time from the missing time to the current time can be set as a range in which the missing person can move.

  Further, according to the information processing apparatus 101, when information indicating the set range is displayed on the map, it is possible to perform control for highlighting a predetermined facility within the range with reference to the facility information of the facility. it can. As a result, the range where the missing person can move is displayed on the map, and when the missing person is seen in the area and the person who seems to be a deceited person is actively protected. You can highlight your facility.

  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 place 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 “●● shrine”, “◇◇ hospital”, It is possible to search for “●● park” with priority, leading to early detection and protection of missing persons.

  Two dotted circles displayed concentrically with the range 121 on the map 120 indicate a range of radius “1 km” and a range of radius “2 km” centered 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.

A landmark is a facility where a person to be monitored is likely to visit, such as a temple, a park, a hospital, or a friend's house. The name is the name of the landmark. The address is a landmark address. The contact information is a landmark telephone number. The guidance rate is a value indicating the degree to which the landmark guides the monitored person. Here, the higher the guidance rate, the higher the degree that the landmark guides the monitored person.

(Memory content of road slope information table 700)
Next, the contents stored in the road slope information table 700 included in the server 201 will be described. The road inclination information table 700 is realized by a storage device such as the memory 302 and the disk 305, for example.

  FIG. 7 is an explanatory diagram showing an example of the contents stored in the road slope information table 700. In FIG. 7, a road inclination information table 700 has fields of an inclination level, a speed variable, and a distance variable, and road inclination information 700-1 to 700-9 is stored as a record by setting information in each field. .

  The inclination level indicates a road gradient, that is, a degree of inclination with respect to a horizontal plane. The slope level “1” indicates no slope (flat ground). An inclination level of 2 or more indicates an upward gradient (uphill), and the higher the inclination level, the larger the upward gradient. An inclination level of −1 or less indicates a downward gradient (downhill), and the lower the inclination level, the larger the downward gradient.

  Here, the moving speed of elderly people when moving on a sloped road tends to be lower than when moving on a flat ground, whether it is uphill or downhill. The speed variable indicates the degree of decrease in the moving speed of the elderly when moving on the road of 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 the case of moving on a flat ground.

  Further, in the present embodiment, when estimating an “arrival position” to be described later, the distance of the road whose moving speed is reduced by x can be regarded as the distance extended by x times the actual distance. For example, the distance of a road whose moving speed is reduced by 70% is regarded as a distance extended by 70% of the actual distance. The distance variable indicates a distance extension corresponding to the degree of decrease in the moving speed corresponding to each inclination level (unit:%).

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

  FIG. 8 is an explanatory diagram illustrating an example of calculating the distance based on the distance variable. In FIG. 8, a section 801 indicates a road having an inclination level “4”. The actual distance of the section 801 is “100 m”. In the case of the inclination level “4”, the speed variable is “30%” and the distance variable is “170%”. Therefore, the distance A of the section 801 is regarded as a distance extended by 70% of the actual distance “100 m”, and “distance A = actual distance × distance variable × 1/100 = 100 m × 1.7 = 170 m”. "

In FIG. 9, the traffic volume / road width information table 900 has fields of a traffic volume level, a road width level, a speed variable, and a distance variable. By setting information in each field, the traffic volume / road width information 900-1 to 900-1 is set. 900-15 is stored as a record.

  The traffic level indicates the traffic volume of the vehicle traveling on the road. The higher the traffic level, the more traffic. The road width level indicates the road width of the road. A higher road width level indicates a wider road. Here, the moving speed of the elderly tends to decrease as the traffic volume increases, and further decreases as the road width 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 traffic volume level and the road width level (unit:%). For example, the speed variable “30%” corresponding to the combination of the traffic volume level “5” and the road width level “1” reduces the movement speed by 70% compared to when traveling on a road with a small traffic volume and a wide road width. It is shown that. The distance variable indicates an extension of the distance according to the degree of decrease in the moving speed corresponding to the combination of the traffic volume level and the road width level (unit:%).

Next, the contents stored in the weather / roof information table 1000 of the server 201 will be described. The weather / roof information table 1000 is realized by a storage device such as the memory 302 and the disk 305, for example.

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

  The weather indicates weather such as rain, cloudy weather, and sunny weather. The roof indicates whether or not a pedestrian roof that prevents rain, solar radiation, and the like is provided on the road. A roof “with” indicates a road with a roof, and a roof “without” indicates a road without a roof. Here, the moving speed of elderly people in rainy weather tends to be lower than that in sunny weather. However, if the road is covered, the degree of decrease in moving speed is 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 presence or absence of a 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 the case of moving on a road when the weather is cloudy. Yes. The distance variable indicates the extension of the distance according to the degree of decrease in the moving speed corresponding to the combination of the weather and the presence or absence of the roof (unit:%).

(Contents stored in the temperature information table 1100)
Next, the storage contents of the temperature information table 1100 that the server 201 has will be described. The temperature information table 1100 is realized by a storage device such as the memory 302 and the disk 305, for example.

  FIG. 11 is an explanatory diagram showing an example of the contents stored in the temperature information table 1100. In FIG. 11, the temperature information table 1100 has fields of temperature, speed variable, and distance variable, and stores the temperature information 1100-1 to 1100-5 as records by setting information in each field.

  The temperature indicates the temperature of the atmosphere (unit: degree). Here, when the temperature is high such as a midsummer day or when the temperature is low such as a midwinter day, the moving speed of the elderly tends to be lower than when the temperature is easy to spend (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%” when the temperature is “40 ° C.” indicates that the moving speed is reduced by 60% compared to the case of moving on the road at a comfortable temperature. The distance variable indicates an extension of the distance corresponding to the degree of decrease in moving speed corresponding to each temperature (unit:%).

(Storage contents of streetlight information table 1200)
Next, the storage contents of the streetlight information table 1200 included in the server 201 will be described. The streetlight information table 1200 is realized by a storage device such as the memory 302 and the disk 305, for example.

  FIG. 12 is an explanatory diagram showing an example of the stored contents of the streetlight information table 1200. In FIG. 12, a streetlight information table 1200 has fields of time zone, streetlight number level, speed variable, and distance variable. 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 in which one day is divided every hour. The street lamp number level indicates the number of street lamps provided on the road. The higher the number of streetlights, the higher the number of streetlights. Here, since the time zone from the evening to about dawn is dark and it is difficult to walk, the moving speed of the elderly tends to decrease compared to other time zones. However, the greater the number of street lamps provided on the road, the smaller the degree of decrease in travel speed.

  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 lamps (unit:%). For example, the speed variable “20%” corresponding to the combination of the time zone “0 o'clock” and the street lamp number level “1” reduces the movement speed by 80% compared to when traveling on a road during bright hours such as noon.

In FIG. 21, the server 201 includes a reception unit 2101, a setting unit 2102, a display control unit 2103, a search unit 2104, and an estimation unit 2105. The accepting unit 2101 to the estimating unit 2105 are functions as control units. Specifically, for example, by causing the CPU 301 to execute a program stored in a storage device such as the memory 302 and 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 in a storage device such as the memory 302 and the disk 305, for example.

  The accepting unit 2101 accepts time information and position information. Here, the time information is information indicating the time when the monitored person is missing (missing time). The position information is information indicating a position (missing place) where the monitored person is missing. Specifically, for example, the reception unit 2101 receives time information and position information by receiving missing person information from the client device 202.

  The setting unit 2102 sets a range corresponding to the 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 in which 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 movement speed V of the monitored person, a predetermined movement speed set in advance, for example, an average movement speed (for example, 3 km / h) of an elderly person suffering from dementia may be used. The setting unit 2102 may select the average moving speed V of the monitored person from among a plurality of speed candidates.

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

  In addition, the average moving speed of elderly people may vary depending on the weather. For example, the moving speed in rainy weather tends to be lower than that in sunny weather. For this reason, for example, the setting unit 2102 may select the moving speed corresponding to the weather at the missing place as the average moving speed V with reference to information indicating the correspondence relationship between the weather and the moving speed.

  Note that the server 201 can identify the weather near the missing place by accessing a server that provides a weather forecast service and acquiring weather information, for example.

  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 monitored person by multiplying the calculated elapsed time T and the average moving speed V of the monitored person. Then, the setting unit 2102 sets, for example, a circular range with the calculated moving distance D as a radius around the position indicated by the received position information.

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

Selection of a landmark as a destination is performed, for example, on a map screen 3200 shown in FIG.

  Based on the elapsed time T from the time indicated by the received time information, the estimation unit 2105 estimates the arrival position when moving on the searched route at a predetermined movement speed. Specifically, for example, the estimation unit 2105 may estimate the position moved by the movement distance D (elapsed time T × average movement speed V) on the searched route as the arrival position. However, when 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 moving speed of elderly people when moving on a sloped road tends to be lower than when moving on flat land, whether it is an uphill or a downhill. For this reason, the estimation unit 2105 may estimate the arrival position on the basis of the gradient (inclination level) of each section on the searched route with reference to road inclination information.

  Specifically, for example, first, the estimation unit 2105 extracts the 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 a distance variable corresponding to the specified inclination level of each section with reference to, for example, the road inclination information table 700 illustrated in FIG.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the identified slope level of each section and the actual distance of each section. The actual distance of each section can be obtained from the start point coordinates and 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 respective sections.

  Then, the estimation unit 2105 may estimate the position moved by the movement distance D on the calculated total distance L as the arrival position. Accordingly, it is possible to estimate the arrival position when moving on the route at the average moving speed V in consideration of the gradient (inclination level) of each section on the route.

  Here, with reference to FIG. 22, an example of estimating the arrival position in consideration of the gradient (inclination level) of each section on the route will be described.

  FIG. 22 is an explanatory diagram illustrating an example of estimating the arrival position. In FIG. 22, a route 2200 is a route from the departure place “Osan's house” to the destination “●● park”. “Home of Mr. XX” is a position where the monitored person is missing (a missing place).

  The route 2200 includes a section 2201, a section 2202, and a section 2203. Here, the actual distances of the sections 2201 to 2203 are each set to “1000 m”. Further, the slope level of the section 2201 is “1”, the slope level of the section 2202 is “4”, and the slope level of the section 2203 is “5”.

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

  Here, the distance variable of the section 2201 is “100%”. For this reason, the distance of the section 2201 is “1000 m (= 1000 m × 100 × 1/100)”. Further, 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 estimation 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 having the calculated total distance L “4650 m” as the arrival position.

  Here, if 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 the movement distance D “3000 m” on the route 2200 having the total distance L “4650 m”. That is, the arrival position is a position 2204 obtained by moving the section 2203 of the distance “1950 m” by “300 m”.

  Returning to the explanation of FIG. 21, as described above, the moving speed of the elderly tends to decrease as the traffic volume increases, and further decreases as the road width decreases. Therefore, the estimation unit 2105 refers to the traffic information on the road and estimates the arrival position based on the traffic volume (traffic volume level, road width level) of each section on the searched route. Good.

  Specifically, for example, first, the estimation unit 2105 refers to the section information of each section on the searched route, and specifies the traffic level and the road width level of each section. Next, for example, the estimation unit 2105 refers to the traffic volume / road width information table 900 illustrated in FIG. 9 and identifies a 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 level and road width level of each identified 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 respective sections. Then, the estimation unit 2105 estimates the position moved by the movement distance D on the calculated total distance L route as the arrival position.

  Thereby, the arrival position when moving on the route at the average moving speed V can be estimated in consideration of the traffic volume (traffic volume level, road width level) of each section on the route.

  In addition, as described above, the moving speed of elderly people during rainy weather tends to be lower than when it is sunny and cloudy. However, if the road is covered, the degree of decrease in moving speed is small. For this reason, the estimation unit 2105 acquires weather information, and when the acquired weather information indicates rainy weather, it is referred to the road roof information and whether each section on the searched route is covered or not. The arrival position may be estimated based on the above.

  Specifically, for example, the estimation unit 2105 first specifies the roof level of each section with reference to the section information of each section on the searched route. Next, for example, the estimation unit 2105 refers to the weather / roof information table 1000 illustrated in FIG. 10 and identifies a distance variable corresponding to the roof level of each identified section.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the identified roof level of each 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 respective sections. Then, the estimation unit 2105 estimates the position moved by the movement distance D on the calculated total distance L route as the arrival position.

  Thereby, the arrival position when moving on the route at the average moving speed V can be estimated in consideration of whether each section on the route is covered.

  Further, as described above, the moving speed of the elderly when the temperature is high or low on a midsummer day, a midwinter day, etc. tends to be lower than when the temperature is easy to spend (for example, 20 degrees). For this reason, the estimation unit 2105 may acquire the temperature information, and the acquired temperature information may estimate the arrival position based on the temperature. The temperature information can be acquired by accessing a server that provides a weather forecast service, for example.

  Specifically, for example, first, the estimation unit 2105 acquires temperature information indicating the temperature of a time zone including the missing time. Next, for example, the estimation unit 2105 refers to the temperature information table 1100 illustrated in FIG. 11 and identifies a distance variable corresponding to the temperature indicated by the acquired temperature information.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the identified 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 respective sections. Then, the estimation unit 2105 estimates the position moved by the movement distance D on the calculated total distance L route as the arrival position.

  Thereby, the arrival position when moving on the route at the average moving speed V can be estimated in consideration of the temperature of the day.

  Further, as described above, the time zone from evening to about dawn is dark and difficult to walk, so the moving speed of the elderly tends to be lower than in other time zones. However, the greater the number of street lamps provided on the road, the smaller the degree of decrease in travel speed. For this reason, when the current time is included in a predetermined time zone, the estimation unit 2105 refers to the street lamp information on the road, and based on the number of street lamps existing in each section on the searched route, May be estimated. The predetermined time zone can be arbitrarily set. For example, the predetermined time zone is set to a time zone from 0:00 to 5:00, a time zone from 17:00 to 23:00, or the like.

  Specifically, for example, first, the estimation unit 2105 refers to the section information of each section on the searched route, and specifies the street lamp number level of each section. Next, for example, the estimation unit 2105 refers to the streetlight information table 1200 illustrated in FIG. 12 and identifies a distance variable corresponding to the streetlight number level of each identified section.

  And the estimation part 2105 calculates the distance of each area based on the distance variable corresponding to the street lamp number level of each identified area, and the actual distance of each area. Next, the estimation unit 2105 calculates the total distance L of the route by accumulating the calculated distances of the respective sections. Then, the estimation unit 2105 estimates the position moved by the movement distance D on the calculated total distance L route as the arrival position.

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

  Further, as described above, the moving speed of elderly people when moving on a road with stairs tends to be lower than 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 existing in each section on the searched route with reference to the road stairs information.

  Specifically, for example, first, the estimation unit 2105 refers to the section information of each section on the searched route and specifies the stair level of each section. Next, for example, the estimation unit 2105 refers to the staircase information table 1300 illustrated in FIG. 13 and identifies a distance variable corresponding to the staircase level of each identified section.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the identified stair level of each 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 respective sections. Then, the estimation unit 2105 estimates the position moved by the movement distance D on the calculated total distance L route as the arrival position.

  Thereby, the arrival position when moving on the route at the average moving speed V can be estimated in consideration of the length of the stairs existing in each section on the route.

  Further, as described above, the movement speed of elderly people when traveling on a road with many passersby tends to be lower than when traveling on a road with few passers-by. For this reason, the estimation unit 2105 may estimate the arrival position based on the amount of people passing through each section on the searched route with reference to road passer information.

  Specifically, for example, the estimation unit 2105 first identifies the passer-by level of each section with reference to the section information of each section on the searched route. Next, for example, the estimation unit 2105 refers to the passer-by information table 1400 illustrated in FIG. 14 and specifies a distance variable corresponding to the passer-by level of each specified section.

  Then, the estimation unit 2105 calculates the distance of each section based on the distance variable corresponding to the passerby level of each identified 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 respective sections. Then, the estimation unit 2105 estimates the position moved by the movement distance D on the calculated total distance L route as the arrival position.

  Thereby, the arrival position when moving on the route at the average moving speed V can be estimated in consideration of the amount of people passing through each section on the route.

  Note that the arrival position may be estimated in consideration of a plurality of factors such as the gradient of each section on the route, the traffic volume, the presence / absence of a roof, the number of street lamps, the length of stairs, passers-by, and air 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 for a plurality of elements and the actual distance of each section.

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

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

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