As a result, the location and type of the disaster and the extent of the disaster are recognized. It is also possible to detect the state of congestion due to obstacles on the road, disaster victims, vehicles, and the like by comparing images of portions corresponding to the road.

  The evacuation route searching means 260 is based on the current position information Gda, the surrounding disaster information Rda, the user status information Ida, the movement capability information Dda, and the significant information Mda transmitted from the server 10 and stored in the significant information storage means 250. Search for the best shelter and route for users. More specifically, the evacuation route searching means 260, as shown in FIG. 8, present location information Gda, user status information Ida, movement capability information Dda, neighboring disaster information Rda, geographical statistical information Sda, congestion information Cda, route Based on the profile Pro and the simulation result Sre, the optimum refuge / evacuation route for the user is searched using the guidance basic information Bda. The geographical statistical information Sda, the congestion information Cda, the route profile Pro, and the simulation result Sre will be described later. The search result Re of the refuge / evacuation route by the evacuation route search means 260 is displayed on the display means 290.

  The display unit 290 displays various information. For example, when a user selects a certain sightseeing function by the sightseeing function selection unit 200 in normal times, the display unit 290 displays the sightseeing information Kda corresponding to the sightseeing function selected by the user. Further, for example, when a user searches for an evacuation route by the evacuation route search means 260 at the time of a disaster, the display means 290 displays the evacuation site / evacuation route search result Re.

  Next, the operation of each component of the server 10 will be described. The user information receiving unit 100 receives user information Yda sent from the mobile terminal device 20. Regarding the user information Yda received by the user information receiving means 100, the sightseeing function selection information Fda is given to the data selection / transmission means 170, and the current location information Gda is given by the data selection / transmission means 170 and the geographical statistical information acquisition means 110. And the operation information Ada is provided to the congestion state determination means 120.

  Based on the current position information Gda sent from each mobile terminal device 20, the geographical statistical information acquisition unit 110 obtains the number of people at each point (that is, the number distribution) and the number of people passing through at each point in a predetermined period in real time. Note that one point may be configured by one position coordinate (minimum unit position coordinate) in the current position information Gda, or one point may be configured by a plurality of position coordinates in the current position information Gda. good. The data obtained by the geographical statistical information acquisition means 110 is stored as the geographical statistical information Sda in the RAM 13 or the auxiliary storage device 14 (see FIG. 3), and the route profile generation means 130, the disaster simulation execution means 140, and the data It is read by the CPU 11 when the function as the selection / transmission means 170 is executed.

  The geographic statistical information Sda includes, for example, the number distribution data having a data format as shown in FIG. 9 and the passing number data having a data format as shown in FIG. Note that the geographical statistical information acquisition unit 110 may obtain the number of people for each road and the number of people passing through each road during a predetermined period.

  By the way, the use timing and use interval of this sightseeing / evacuation guidance application 30 are different for each user. For this reason, in order to obtain information on the number distribution and information on the number of people passing through each point in real time, it is necessary to interpolate the information. Therefore, in the present embodiment, when location information of a certain user (hereinafter referred to as “user X”) cannot be acquired at the most recent time, as described below, The position coordinates (current position) are predicted.

  A specific example of this prediction will be described with reference to FIG. In addition, regarding the route shown in FIG. 11, for convenience of explanation, it is assumed that the time required for moving from the point B to the point C and the time required for moving from the point B to the point D are both 30 minutes. For example, based on past data, it is assumed that a person who has moved from point A to point B tends to move to point C next. Here, it is assumed that the user X moves from the point A toward the point B and reaches the point B at 10:00. In such a case, if the position information about the user X cannot be acquired after 10 o'clock, a prediction is made that “the user X is at the point C at 10:30”.

  Based on past data, 90% of people who moved from point A to point B moved from point B to point C, and 10% of people moved from point B to point D. Assume. In such a case, if there are 10 users moving in the same way as User X, “9 out of 10 people were at point C at 10:30 and the remaining one was 10:00. A prediction is made that "I will be at point D in 30 minutes". By performing such prediction, the number distribution and the like at each time point are estimated based on information of a large number of users. The specific prediction method is not limited to the above-described example as long as the position coordinates can be statistically obtained using past data.

  In order to perform the prediction as described above, it is necessary to accumulate each user's behavior (movement) history as data. Therefore, the geographical statistical information acquisition unit 110 includes a behavior profile generation unit 112 that generates a behavior profile in which data indicating a user's movement tendency in the past is stored. The behavior profile has a data format as shown in FIG. 12, for example. In this example, the ratio of the person who next moves to the third point among the persons who moved from the first point to the second point is held in the action profile as data.

  Further, by providing “day of the week” and “weather” in the data item, it becomes possible to hold the movement tendency for each day of the week and the movement tendency for each weather as data. The behavior profile generation means 112 generates such a behavior profile with reference to guidance basic information Bda described later, based on current position information Gda transmitted from each portable terminal device 20 as needed. The behavior profile is used for predicting the position coordinates (current position) of the user as described above.

  Based on the operation information Ada sent from each mobile terminal device 20, the congestion state determination unit 120 determines the congestion state in each route while referring to guidance basic information Bda described later. The determination result by the congestion state determination unit 120 is stored as congestion information Cda in the RAM 13 or the auxiliary storage device 14 (see FIG. 3), and is used as the route profile generation unit 130, the disaster simulation execution unit 140, and the data selection / transmission unit 170. When the function is executed, it is read by the CPU 11.

  FIG. 13 is an example of a data format of the congestion information Cda generated by the congestion state determination unit 120. As shown in FIG. 13, the congestion information Cda is composed of position data (start point and end point data) of each route and congestion data of the route. The congestion state determination unit 120 may determine the congestion state at each point.

  As described above, the motion information Ada is information representing a person's motion / behavior, such as “stopped”, “running”, and “sitting”. Based on this operation information Ada, for example, if there are many people who are “stopped” in a certain route, it can be determined that “the congestion degree of the route is high”. Further, for example, if there is any person who is “running” on a certain route, it can be determined that “the congestion degree of the route is relatively low”. The congestion degree may be expressed in a plurality of levels (for example, 5 levels), may be expressed in percentage, or may be expressed in other units.

  Based on the geographical statistical information Sda and the congestion information Cda, the route profile generation means 130 generates a route profile Pro in which data indicating the characteristics of each route is stored while referring to guidance basic information Bda described later. In other words, the route profile generation unit 130 obtains long-term characteristics for each route based on the information on the number of people acquired and accumulated in normal times, the number of people passing (at each point), and the degree of congestion. The route profile Pro is stored in the RAM 13 or the auxiliary storage device 14 (see FIG. 3), and is read out by the CPU 11 when functions as the disaster simulation execution unit 140 and the data selection / transmission unit 170 are executed.

  In the present embodiment, the characteristics of each route are represented by the number of people who can pass within a predetermined period and the moving speed. The route profile Pro has a data format as shown in FIG. 14, for example. 14, “movement speed A” is a movement speed when moving from the start point side to the end point side, and “movement speed B” is a movement speed when moving from the end point side to the start point side. The reason why the moving speed A and the moving speed B exist in this way is that, for example, the speed of walking up and down differs on a slope.

  In addition, by providing “day of the week” and “weather” in the data item, it is possible to hold the characteristics for each day of the week and the characteristics for each weather as data. Such a route profile Pro is used for simulation by the disaster simulation execution means 140 (prediction of congestion at each point / each route when a disaster occurs), and is sent to the mobile terminal device 20 for evacuation route search means. 260 is used to search for a shelter / evacuation route.

  The disaster simulation execution means 140 uses the geographical statistical information Sda, the congestion information Cda, the route profile Pro, and the guidance basic information Bda described later to predict the congestion degree of each point / route when a disaster occurs. Are executed at predetermined time intervals. In other words, the disaster simulation execution means 140 is based on the distribution of the number of people acquired and accumulated in normal times, the number of people passing (at each point), the degree of congestion, and the long-term characteristics of each route. Predict the degree of congestion of points and each route.

  The simulation result Sre by the disaster simulation execution means 140 is stored in the RAM 13 or the auxiliary storage device 14 (see FIG. 3), and is read out by the CPU 11 when the function as the data selection / transmission means 170 is executed. The simulation result Sre includes, for example, point-specific prediction congestion degree data having a data format as shown in FIG. 15 and route-specific prediction congestion degree data having a data format as shown in FIG. Such a simulation result Sre is transmitted to each mobile terminal device 20 by the data selection / transmission unit 170 at regular time intervals, and is used for the search for the evacuation site / evacuation route by the evacuation route search unit 260.

  The guidance basic information storage unit 150 stores guidance basic information Bda that is necessary when searching for an evacuation route. The guidance basic information Bda includes a map, road information, shelter information, and the like. FIG. 17 is a diagram illustrating an example of a data format of road information. As shown in FIG. 17, the road information includes position data (start point and end point data) of each road, distance data from the start point to the end point, road width data, and the like. FIG. 18 is a diagram illustrating an example of a data format of refuge information. As shown in FIG. 18, the shelter information is composed of data on the position of the shelter, data on the number of persons accommodated, data on the presence / absence of a doctor, data on the status of food stockpile, and the like. The guidance basic information storage unit 150 is realized by the auxiliary storage device 14 as hardware.

  The surrounding past information storage unit 155 stores the surrounding past information Pda for recognizing the damage situation around the user at the time of the disaster compared with the surrounding current information Vda by the surrounding state recognition unit 280. In the past past information Pda, there are information (still images or moving images) taken of roads and surrounding buildings, standing trees, rivers, etc. at a certain time in the past, and information on the location where the image was taken and the posture at the time of taking the image. include.

  FIG. 19 is a diagram illustrating an example of a data format of the surrounding past information Pda. As shown in FIG. 19, the surrounding past information Pda includes the position (latitude, longitude, altitude may be included) at which the video was shot, the direction, the elevation angle and depression angle of the camera used for shooting, and the shot. It consists of video data and the like. The peripheral past information storage unit 155 is realized by the auxiliary storage device 14 as hardware. The surrounding past information Pda is obtained by collecting and collecting images of all directions of 360 degrees from a vehicle or the like traveling on a road during normal times so that users who can exist in various places can be flexibly handled. It is preferable to keep it.

  In the tourist information storage means 160, there is tourist information Kda which is various information (tourist facility information, tourist course information, accommodation facility / restaurant / souvenir store information, etc.) to be provided to the user by the tourist app 32. Stored. The tourist information storage means 160 is realized by the auxiliary storage device 14 as hardware.

  The data selection / transmission means 170 transmits significant information Mda, surrounding past information Pda, and sightseeing information Kda to the mobile terminal device 20. The significant information Mda includes geographical statistical information Sda, congestion information Cda, route profile Pro, simulation result Sre, and guidance basic information Bda. By the way, transmitting all information (all significant information Mda, all past past information Pda, and all tourism information Kda) held by the server 10 to the mobile terminal device 20 is stored in the mobile terminal device 20. Considering the capacity and communication time for data transmission, it is not realistic.

  Therefore, in order to transmit only necessary information for each portable terminal device 20 from the server 10, the data selection / transmission means 170 includes significant information selection means 172, surrounding past information selection means 173, and sightseeing information selection means. 174 is included. Significant information selection means 172 selects only significant information Mda necessary for searching for shelters / evacuation routes in each mobile terminal device 20 based on the current position information Gda sent from each mobile terminal device 20.
