A2. Acquisition and use of evacuation information:
FIG. 2 is a flowchart showing processing of the mobile phone 200 when acquiring and outputting evacuation information. The process of FIG. 2 is not automatically triggered by the user's operation of the mobile phone 200, but is automatically performed by the main control unit 210 of the mobile phone 200.

  In step S <b> 10, the main control unit 210 acquires current position information from the GPS unit 201. Then, the main control unit 210 stores the acquired current position information in the RAM. The process of step S10 is repeatedly performed through the processes of steps S27 and S45 described later. The process of step S10 is performed every 10 seconds, for example. In addition, the function part of the main control part 210 which implement | achieves the function of step S10 is shown as the position measurement unit 231 in FIG.

  In step S <b> 20, the main control unit 210 acquires attribute information of the point represented by the current position information from the route search server 100 via the communication unit 205. The request for attribute information in step S20 is transmitted to the route search server 100 together with the current position information. The main control unit 210 receives the attribute information of the point represented by the current position information from the route search server 100 and stores it in the RAM 212.

  In step S25, the main control unit 210 determines whether the attribute represented by the attribute information received in step S20 is “accommodation facility” or “business establishment”. If the attribute is “accommodation facility” or “business establishment”, the process proceeds to step S30. Otherwise, the process proceeds to step S27.

  In step S27, the main control unit 210 determines whether or not the frequency of the user visiting an area such as a facility including the position represented by the current position information during the past time Ps is greater than or equal to Th. More specifically, among the current position information acquired during the past time Ps (for example, 180 days) and stored in the RAM 212, attribute information (for example, “○” It is determined whether or not the number of current position information representing points having the same attribute information as “shopping center” and “xx station” is equal to or greater than Th. The threshold value Th can be set to an appropriate value (for example, Th = 2500) from integers of 2 or more.

  If the determination result in step S27 is Yes, the user frequently visits the spot. If the determination result of step S27 is No, the process returns to step S10. If the determination result is Yes, the process proceeds to step S30.

  In step S30, the main control unit 210 of the mobile phone 200 requests the route search server 100 to search for a route from the current location to the evacuation site closest to the current location with the latest current location information. In response to the request from the mobile phone 200, the route search server 100 searches for a route from the point indicated by the current position information received together with the request to the nearest evacuation site. Then, route data representing the route is transmitted to the mobile phone 200. The route data to be transmitted may include attribute information such as the available facilities at the evacuation site, the number of people that can be accommodated, and the estimated number of days of consumption of the stored food.

  In step S <b> 30, the main control unit 210 of the mobile phone 200 requests the map server 150 for map image data around the route including the route represented by the route data received from the route search server 100. A request for a map image to the map server 150 is made with position information obtained from route data. In response to the request from the mobile phone 200, the map server 150 extracts a map image based on the route data. Then, the map server 150 transmits the map image data to the mobile phone 200. The mobile phone 200 receives the data transmitted from the route search server 100.

  The map image data transmission request to the mobile phone 200 to the map server 150 is sent to the map server 150 when the route search server 100 is requested by the mobile phone 200 to search for a route to the evacuation site. It may be done.

  The route data including the attribute information of the evacuation site and the information of the map image data required for the route search server 100 and the map server 150 in step S30 are collectively referred to as “evacuation information”. In addition, the function part of the main control part 210 which implement | achieves the function of step S30 is shown as the refuge area information acquisition unit 232 in FIG.

Information on the route from the place to the nearest evacuation site and information on the evacuation site is automatically acquired. For example, an “accommodation facility” is a place where the user is expected to sleep later. The “business office” is a place where the user is expected to work afterwards. For this reason, after a user visits the place, even if a disaster occurs and the information on the route and the evacuation place cannot be acquired through the communication line, the user uses the information stored in the RAM 212. be able to.

  Moreover, in the determination of step S25, the determination of Yes is also performed when the visit frequency does not exceed the predetermined value (see step S27). For this reason, the visit frequency in the long term is not so high that it is determined as Yes in step S27, that is, when staying at the office for only several hours on a day trip or for a short period such as 1 night, 2 nights, etc. Evacuation information is also acquired when staying at a hotel.

  For example, assume that the user visits the company Of2 for a day trip (see FIG. 3). In such a case, when the current position information is acquired in the company Of2 (see step S10 in FIG. 2), the determination result in step S25 is Yes. As a result, evacuation information is acquired in step S30. Specifically, attribute information such as the evacuation route ER7 from the company Of2 to the evacuation site EA7, the area EM7 map image, and the equipment available for the evacuation site EA7 is acquired.

  In addition, in both the process of step S25 and the process of step S27 in FIG. 2, there is a point that reaches step S30. For example, the company Of1 where the user normally commutes brings a determination result of Yes in both steps S25 and S27, and reaches step S30. In step S30, the evacuation information already stored in the RAM 212 is not requested again from the route search server 100. By setting it as such an aspect, the load of the route search server 100, the map server 150, the communication carrier server 190, the mobile phone 200, and the communication line can be reduced.

  In step S <b> 45 of FIG. 2, the main control unit 210 of the mobile phone 200 determines whether disaster occurrence data has been received from the Japan Meteorological Agency server 300. If disaster occurrence data has been received, the process proceeds to step S50. If disaster occurrence data has not been received, the process returns to step S10.

  In step S <b> 50, the main control unit 210 of the mobile phone 200 outputs a sound from the sound output unit 203 and generates a vibration by the vibration mechanism 204 to issue a warning to the user. Then, the main control unit 210 displays a map image and an evacuation route on the display panel 202 with a predetermined operation of the command input unit 206 performed by the user thereafter. More specifically, the main control unit 210 selects the evacuation information stored in the RAM and associated with the position represented by the latest current position information. Such evacuation information includes information on the evacuation place closest to the current position. Then, the main control unit 210 displays the evacuation route and the map image on the display panel 202 based on the evacuation information.

  For example, when the user is in the company Of1 shown in the upper right of FIG. 3, the company Of1 that is the current position is included based on the evacuation route ER4 stored in the RAM and the map image data of the area EM4. A map of the predetermined area DA and a part of the evacuation route ER4 are displayed on the display panel 202. At the same time, attribute information of the evacuation site EA4 (available facilities, the number of people that can be accommodated, etc.) is also displayed. Note that the user can enlarge, reduce, and move the range of the map to be displayed by operating the command input unit 206 of the mobile phone 200.

  In step S60, the main control unit 210 of the mobile phone 200 is triggered by a predetermined operation of the command input unit 206 by the user, and is obtained via the route data, map image data, and GPS unit 201 included in the evacuation information. Based on the position information, route guidance is performed via the display panel 202 and the audio output unit 203. In addition, the function part of the main control part 210 which implement | achieves the function of step S50, S60 is shown as the information output unit 234 in FIG.

  According to such an aspect, even when the communication line is interrupted or becomes unstable due to a disaster, the user can move to the evacuation site by using the information regarding the evacuation site.

  In this embodiment, the GPS unit 201 corresponds to a “position measuring unit” in the claims. The communication unit 205 corresponds to a “communication unit” in the claims. The RAM 212 corresponds to a “storage unit” in the claims. The display panel 202, the audio output unit 203, and the vibration mechanism 204 correspond to an “output unit” in the claims. The main control unit 210 corresponds to a “control unit” in the claims.

In this embodiment, step S10 corresponds to a “measurement position information acquisition step” in the claims. Step S20 corresponds to the “measurement point attribute information acquisition step” in the claims. Step S30 corresponds to a “first type evacuation site information acquisition step” in the claims. Step S40 corresponds to the “first type evacuation site information storage step” in the claims.
Steps S50 and S60 correspond to an “output step” in the claims.

  In this embodiment, the condition determined in step S25 corresponds to the “first sub-condition” in the claims. The determination condition in step S25 is that the current location represented by the current position information acquired before (previous) determination in step S25 exists once in the facility area within a predetermined time interval (threshold Th). = 1). That is, in step S25, Th1 = 1. The condition determined in step S27 corresponds to the “second sub-condition” in the claims. In step S27, Th2 ≧ 2. The conditions determined in steps S25 and S27 correspond to the “first acquisition condition” in the claims. Here, the “first acquisition condition” has been described as configured from the conditions determined in steps S25 and S27, but the “first acquisition condition” is configured from other determination conditions. It is good.

B. Second embodiment:
In the first embodiment, evacuation information is acquired for the position represented by the current position information (see steps S30 and S40 in FIG. 2). However, in the second embodiment, evacuation information may be acquired for other positions in addition to the position represented by the current position information. That is, the second embodiment is different from the first embodiment in the process of step S30 of FIG. 2 in the first embodiment. The other points of the second embodiment are the same as those of the first embodiment.

  FIG. 4 is a flowchart showing the contents of the process for requesting evacuation information (see step S30 in FIG. 2) in the second embodiment. In step S305, the main control unit 210 of the mobile phone 200 determines whether or not the current position is a transportation station based on the attribute information of the current position acquired in step S20. If the current position is a transportation station, the process proceeds to step S307. Otherwise, the process proceeds to step S310.

  In step S307, the main control unit 210 of the mobile phone 200 determines whether evacuation information for a station different from the station at the current position is stored in the RAM 212. If such evacuation information is stored in the RAM 212, the process proceeds to step S320. Otherwise, the process proceeds to step S310.

  In step S310, the main control unit 210 of the mobile phone 200 requests the route search server 100 to search for a route from the current location to the evacuation site closest to the current location with the latest current location information. The route data is received from the route search server 100. In addition, the main control unit 210 of the mobile phone 200 requests the map server 150 for map image data around the route including the route represented by the route data received from the route search server 100. Then, map image data around the route is received from the map server 150. The subsequent processing is the same as that after step S40 in the first embodiment.

  On the other hand, in step S320 of FIG. 4, the main control unit 210 of the mobile phone 200 requests the route search server 100 to search for a route from the station at the current position to the station where the evacuation information is stored in the RAM 212. . Then, the route search server 100 obtains route data including position information of stations on the way (including stop stations and passing stations). When there are a plurality of stations in the RAM 212 where evacuation information is already stored, a request for searching for a plurality of routes is made to the route search server 100. Here, a plurality of evacuation information and the like are stored in the RAM 212.

  In step S330, the main control unit 210 of the mobile phone 200 requests the route search server 100 to search for the route to the nearest evacuation site for the current position and the station on the way. Then, the route data is received from the route search server 100. In addition, the main control unit 210 of the mobile phone 200 requests the map server 150 for map image data around the route including the route represented by the route data received from the route search server 100. Then, the map image data is received from the map server 150. The subsequent processing is the same as that after step S40 in the first embodiment.

  For example, in the map of FIG. 3, it is assumed that the user is using a section of the train line L1 from the nearest station St1 of his home Hm to the nearest station St2 of the company. The station on the way is station St3.

  In such a case, first, the visit frequency in the period Ps exceeds Th for either the station St1 or the station St2, and the determination result in step S27 of FIG. 2 is Yes. As a result, evacuation information is acquired for the station. For example, it is assumed that evacuation information is acquired for the nearest station St1 of the home Hm. The evacuation information includes attribute information such as the evacuation route ER2 from the station St1 to the evacuation site EA2, the map image data of the area EM2 indicated by the alternate long and short dash line, and the equipment available for the evacuation site EA2.

After that, for the nearest station St2 of the company, the visit frequency in the period Ps exceeds Th, the determination result in step S27 of FIG. 2 is Yes, and the process of step S30 (see FIG. 4) is performed. At this time, the evacuation information for the station St1 is already stored in the RAM 212. For this reason, the determination result of step S307 in FIG. 4 is Yes. as a result,
In addition to the evacuation information of the current station St2, the evacuation information of the station St3 is also requested (step S330).

  That is, in step S330, the evacuation route ER3 from the station St2 to the evacuation site EA3, the map image data of the area EM3, the evacuation information including attribute information such as the available facilities of the evacuation site EA3, and the evacuation site from the station St3 Evacuation route ER5 to EA5, map image data of area EM5, and evacuation information including attribute information such as available facilities of evacuation site EA5 are requested and acquired.

  In such an aspect, since the station is a station through which a user usually travels such as a train or a station that stops only for a very short time, the visit frequency is threshold in the process of step S27 in FIG. Evacuation information is also acquired for stations that do not exceed the value Th.

  In the event of a disaster, the transportation means such as a train may not travel to the station where the user is scheduled to get off, and may stop at the nearest station from the location at the time of the disaster. In the second embodiment, even in such a case, evacuation information including an evacuation route from a station of transportation means such as a train (for example, station St3) to the nearest evacuation site (for example, evacuation site EA5) is acquired in advance. Yes. Therefore, the user can quickly move to the evacuation site according to the route guidance performed by the mobile phone 200.

  In the present embodiment, step S330 corresponds to the “second type evacuation site information acquisition step” in the claims. Step S40 corresponds to the “second-type refuge area information storage step” in the claims. The conditions determined in steps S305 and S307 correspond to the “second acquisition condition” in the claims. Here, the “second acquisition condition” has been described as configured from the conditions determined in steps S305 and S307, but the “second acquisition condition” is configured from other determination conditions. It is good.

C. Variation:
The present invention is not limited to the above-described examples and embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

C1. Modification 1:
In the above embodiment, it is determined whether or not the attribute of the current position is “accommodation facility” or “business establishment” in the determination regarding the attribute in step S25 of FIG. However, in the determination in step S25 of FIG. 2, it is possible to proceed to the information request processing in step S30 even when the attribute of the current position is another attribute.

  For example, when the attribute of the current position is “station”, the user is expected to wait for the transportation means such as a train, a bus, a ship, and an aircraft at the station for a while after that. For this reason, it is preferable to make an information request even when the attribute of the current position is “station”. In such an embodiment, for example, in the example of FIG. 3, the evacuation route ER6 from the station St4 on the route L2 used for the day trip to the nearest evacuation site EA6, the attribute information of the evacuation site EA6, and the map of the area EM6 Image data is acquired.

C2. Modification 2:
In the said Example, both determination of step S25 based on an attribute and determination of step S27 based on a frequency are performed as determination of whether to acquire evacuation information (refer FIG. 2). However, it is also possible to adopt a mode in which only one of the determination based on the attribute and the determination based on the frequency is performed. Since the determination in step S25 is based on the attribute information of the actual current position, the user has visited the facility having the attribute information once. That is, the determination condition in step S25 is that the current location represented by the current position information acquired before (previous) determination in step S25 exists once in the area of the facility within a predetermined time interval (threshold value). It can be said that the condition of value Th = 1) is included.

  That is, in the above embodiment, the frequency threshold Th is 1 in the determination in step S25, and the frequency threshold Th is a predetermined number of 2 or more in the determination in step S27.

  In the determination in step S25, it is also possible to make a determination regarding the frequency as in step S27. However, the frequency threshold in the determination in step S25 is preferably smaller than the frequency threshold in the determination in step S27.

C3. Modification 3:
In the above embodiment, the “region” for determining whether or not the current position is included in step S27 is a region having attribute information of the same facility. However, the “area” used when determining the frequency in step S27 can be an area defined by another method.

  For example, the “region” used when determining the frequency may be a region having a predetermined size and shape including the latest “current position”. More specifically, the “region” used when determining the frequency may be a circular region having a radius r centered on the latest “current position”. Further, for example, the entire area in which the map database has map data can be divided into a plurality of areas in advance, and the area including the latest “current position” can be set as the “predetermined area”.

C4. Modification 4:
In the above-described embodiment, the evacuation information already stored in the RAM 212 is not requested again from the route search server 100. However, it is more preferable that the evacuation information for each point is repeatedly acquired. For example, it is preferable that the evacuation information is acquired again for a certain point or facility (area) when a certain period has elapsed since the evacuation information was last acquired. Moreover, when evacuation information is acquired, the visit frequency in the past time section Ps is set to 0, and when the frequency becomes Th or more next time, the evacuation information may be acquired again. .

C5. Modification 5:
In the above embodiment, the information acquired by the mobile phone 200 in steps S30 and S40 in FIG. 2 includes information on route data and map image data. However, the information automatically acquired through the communication line by the mobile phone 200 as the information processing apparatus may be other information.

  For example, the information automatically acquired by the information processing apparatus may be only the attribute information of the evacuation site. The number of evacuation sites at that time is, for example, (i) the nearest evacuation site where a predetermined condition is satisfied, (ii) N points from the closest point to the point satisfying the predetermined condition (N is 2) (Iii) an evacuation place within a predetermined distance from a point satisfying a predetermined condition. Even in such a mode, the user can move to the evacuation site with reference to the information in a situation where the communication line cannot be sufficiently used.

  Further, for example, the information automatically acquired by the information processing apparatus can be information on the nearest toilet at a point that satisfies a predetermined condition. According to such an aspect, the user can add to the toilet by referring to the information in a situation where the communication line cannot be sufficiently used, and can use the water supply.

  The information automatically acquired by the information processing apparatus may be information regarding a convenience store nearest to a point that satisfies a predetermined condition. With such an aspect, the user can use the convenience store with reference to the information in a situation where the communication line cannot be sufficiently used. Convenience stores may release some products in the event of a disaster. For this reason, it is also possible to obtain the released product using the above information.

  In addition, route data representing a route to one or more evacuation sites, toilets, and convenience stores can be included. That is, the information automatically acquired by the information processing apparatus can be various information relating to a point that satisfies a predetermined condition and that is different from the point. In other words, a toilet and a convenience store are included in the broader “evacuation site” in this specification.

C6. Modification 6:
In the above embodiment, the display based on the evacuation information is performed in response to the reception of the disaster occurrence data transmitted from the Meteorological Agency server 300 (see steps S45 and S50 in FIG. 2). However, the display based on the evacuation information may be performed in response to the occurrence of another event.

  For example, due to the occurrence of a disaster, a display based on evacuation information is performed on the screen that is initially displayed during data communication by the mobile phone 200, triggered by the mobile phone operator performing a predetermined display. You can also In addition, display based on evacuation information triggered by the fact that the mobile phone 200 has received a notification from a mobile phone operator or a third party other than the Japan Meteorological Agency that provides a service notifying the occurrence of a disaster. Can also be done. Furthermore, it is also possible to perform display based on the evacuation information when the user uses the disaster message dial and terminates the use. That is, the event that triggers the display based on the information received and stored in advance can be various events resulting from the occurrence of a disaster.

C7. Modification 7:
In the above embodiment, in step S50, the evacuation route and the map image are displayed on the display panel 202 based on the evacuation information including information on the evacuation place closest to the position represented by the latest current position information. However, the information used when output is performed on the display panel 202 as the output unit may include evacuation information other than the evacuation information related to the latest current position information.

  For example, the evacuation information used in the display can be evacuation information selected based on a point determined based on the “current position” in a past predetermined time interval (for example, several minutes) including the current time. . The point may be a point as a center of gravity obtained by averaging the “current position” in a past predetermined time interval including the current time. In addition, when the area on the map is divided into minute areas (for example, grid areas with intervals of several meters), the point is in the minute area having the highest presence frequency in the past predetermined time section including the current time. It can also be a predetermined point.

  And in the said Example, the evacuation information utilized in the case of an output is a set of evacuation information. However, the evacuation information used at the time of output can be two or more sets of evacuation information. In such a case, for example, information on a plurality of evacuation sites can be output.

C8. Modification 8:
In the above embodiment, the display of the map and evacuation route in step S50 of FIG. 2 and the route guidance in step S60 are performed with a predetermined operation of the command input unit 206 by the user as a trigger. However, these processes can be automatically performed without the user's operation of the portable terminal. In addition, it is preferable that the acquisition of evacuation information (steps S10 to S40 in FIG. 2) is automatically performed without any user operation.

C9. Modification 9:
Map image data as image data stored in the map database 156 of the map server 150 may be stored as raster data or may be stored as vector data. The map image data transmitted to the mobile phone 200 as a terminal device carried by the user may be raster data or vector data. Further, one of the map image data in the map database 156 and the map image data transmitted to the terminal device can be vector data and the other can be raster data.

  In the above embodiment, the map image data that is normally used and the map image data transmitted to the mobile phone 200 as the evacuation information are data extracted from the same map database 156. However, the map image data transmitted to the mobile phone 200 as the evacuation information can be map image data different from the map image data used for normal route search and route guidance. For example, the map image data transmitted to the mobile phone 200 as evacuation information is map image data with a smaller data amount when representing the same region than the map image data used for normal route search and route guidance. Is preferred.

C10. Modification 10:
In the above embodiment, the output unit that provides information to the user is configured as the display panel 202, the audio output unit 203, and the vibration mechanism 204 (see FIG. 1). However, the output unit can output information in the form of a printed matter, or can output information with unevenness constituting Braille. The output unit only needs to be able to provide information to the user in some form such as an image, sound, touch, or vibration.

C11. Modification 11:
In the above-described embodiment, a system is used in which a current position is identified by receiving radio waves from a GPS (Global Positioning System / Global Positioning System) satellite. The current position acquisition unit as a component of the guidance device may be based on any principle or use a system operated by any institution as long as the current position can be specified.

C12. Modification 12:
In the above embodiment, an example in which the route includes a train line has been described. However, the present invention can be applied to route guidance in the case where various routes such as a route bus, a regular ferry, and an aircraft are included in the route in addition to the train. That is, the route included in the route may be “a route on which the transportation means is operated on a predetermined route”.

C13. Modification 13:
In the above embodiment, the route guidance system includes the route search server 100, the map server 150, the telecommunications carrier server 190, and the mobile phone 200 as its components. However, for example, the route search server 100 and the map server 150 may be the same server. The carrier server 190, the route search server 100, and the map server 150 may be the same server.

  That is, the route guidance system as a guidance device may be one device in which each component is housed in one housing. Further, the route guidance system as a guidance device may be configured as two or more devices whose constituent elements are connected to each other by a data communication line. For each function such as a function for generating route information and a function for generating map information, one or more arbitrary functions can be assigned to each device. Each function may be realized by one device, or two or more devices may be realized in cooperation. In an aspect in which two or more components are connected by a communication line, the output unit that outputs information to the user is preferably carried by the user.

C14. Modification 14:
In the above embodiment, a part of the configuration realized by hardware may be replaced with software, and conversely, a part of the configuration realized by software may be replaced by hardware. For example, a part of the function of the application software 230 (FIG. 1) can be executed by the control circuit.

  A computer program for realizing such a function is provided in a form recorded on a computer-readable recording medium such as a floppy disk or a CD-ROM. The host computer reads the computer program from the recording medium and transfers it to the internal storage device or the external storage device. Alternatively, the computer program may be supplied from the program supply device to the host computer via a communication path. When realizing the function of the computer program, the computer program stored in the internal storage device is executed by the microprocessor of the host computer. Further, the host computer may directly execute the computer program recorded on the recording medium.

  In this specification, the host computer is a concept including a hardware device and an operation system, and means a hardware device that operates under the control of the operation system. The computer program causes such a host computer to realize the functions of the above-described units. Note that some of the functions described above may be realized by an operation system instead of an application program.

  In the present invention, the “computer-readable recording medium” is not limited to a portable recording medium such as a flexible disk or a CD-ROM, but an internal storage device in a computer such as various RAMs and ROMs, An external storage device fixed to a computer such as a hard disk is also included.
