As one of such application software, application software called “route search application” for guiding a user (hereinafter referred to as “user”) of a mobile terminal device to a destination is known. By using the route search application, the user can easily reach the destination even when there is no map at hand.

  In general, in a system that implements a route search application, basic data (map and road data) required to execute a route search is held in a server. Then, when the user uses the route search application, necessary data is downloaded from the server to the mobile terminal device. Thereby, the mobile terminal device can execute a route search without holding a huge amount of data inside.

  By the way, in recent years, it is important to promptly guide people to evacuation shelters when disasters such as earthquakes occur. In particular, guiding tourists who are not familiar with the land to evacuation centers is an important issue. In this regard, since mobile terminal devices such as mobile phones have become widespread in recent years, it is considered to guide a user to an evacuation site using a mobile terminal device when a disaster occurs.

May be. In such a case, the mobile terminal device cannot search and display the evacuation route.

  Therefore, Japanese Patent Application Laid-Open No. 2007-147340 discloses that the mobile terminal device can provide route guidance of the evacuation route even when a disaster occurs and communication between the server and the mobile terminal device is not possible. An invention of an evacuation route providing system is disclosed. According to this evacuation route providing system, evacuation route and map data are regularly downloaded from the route search server to the mobile terminal device during normal times. When communication between the mobile terminal device and the route search server is interrupted due to the occurrence of a disaster, etc., the evacuation route is displayed on the display means of the mobile terminal device based on the data downloaded in normal times. Is done. In this way, it is possible to provide evacuation route information to the user even when a failure has occurred in the communication infrastructure.

Disaster information input means is realized.

  First, the operation of each component of the mobile terminal device 20 will be described. The sightseeing function selection means 200 is a means for allowing the user to select a sightseeing function desired by the user (presentation of various information on sightseeing facilities, guidance on sightseeing courses, introduction of accommodation facilities / restaurants / souvenir shops, etc.). When the user selects a sightseeing function, the sightseeing function selection means 200 outputs function selection information Fda indicating the sightseeing function selected by the user. The GPS information acquisition unit 210 acquires position information (latitude / longitude information) for specifying the current position of the user based on radio waves received from GPS satellites, and outputs GPS information Gda indicating the position information. The GPS information acquisition unit 210 is realized by the GPS processing unit 25 (see FIG. 4) as hardware.

  The user information transmission means 230 transmits the function selection information Fda, GPS information Gda, and operation information Ada to the server 10 as user information Yda. Note that the GPS information Gda and the operation information Ada are, for example, at the timing when the user activates the sightseeing / evacuation guidance application 30 and the timing when the user performs some operation using the sightseeing / evacuation guidance application 30. 20 to the server 10. Further, the GPS information Gda and the operation information Ada may be transmitted from the mobile terminal device 20 to the server 10 every predetermined period while the user is using the sightseeing / evacuation guidance application 30.

  The data receiving unit 240 receives data transmitted from the server 10. From the server 10 to the mobile terminal device 20, significant information Mda that is useful data for searching for an evacuation route, and tourism information Kda that is data corresponding to the tourism function selected by the user by the tourism function selection unit 200, Is sent. The significant information Mda transmitted from the server 10 is stored in the significant information storage unit 250. The significant information storage means 250 is realized by a flash ROM 22 or RAM 23 (see FIG. 4) as hardware.

  The personal situation input means 271 is a means for allowing the user to input the disaster situation and exercise ability (ability to avoid or overcome obstacles on the evacuation route) when the disaster occurs. The personal status input means 271 is realized by displaying a screen as shown in FIG. As shown in FIG. 6, for example, “climbing”, “running”, “flat only”, “wheelchair”, “foot injury”, “cannot walk”, “stretcher”, “children”, “pram”, etc. Button is displayed. The user only has to press a button indicating the corresponding state. The personal status information Ida indicating the content input by the personal status input means 271 is used by the evacuation route search means 260.

  Note that the screen shown in FIG. 6 is an example, and the screen layout and items displayed on the screen are not limited thereto. This also applies to the movable distance input means 272 (see FIG. 7) and the surrounding situation input means 280 (see FIG. 8) described later.

  The movable distance input means 272 is a means for causing the user (a disaster victim) to input a moving means and a movable distance when a disaster occurs. This movable distance input means 272 is realized by displaying a screen as shown in FIG. As shown in FIG. 7, for example, buttons indicating moving means such as “walking”, “bicycle”, “car”, and an input box capable of inputting a movable distance are displayed. The user presses a button indicating the corresponding moving means and inputs the movable distance. The movement capability information Dda indicating the content input by the movable distance input unit 272 is used by the evacuation route search unit 260.

  The peripheral status input means 280 is a means for allowing the user to input the peripheral status of the user (disaster) when a disaster occurs. This peripheral state input means 280 is realized by displaying a screen as shown in FIG. As shown in FIG. 8, the surrounding situation input means 280 is configured to be able to input, for example, a disaster situation and a congestion situation. The area for entering the disaster status includes, for example, buttons indicating the type of disaster such as “fire”, “water damage”, “collapse”, “cracking”, “strong”, “strong”, “medium” , A button indicating the intensity of the disaster such as “weak” and an input box capable of inputting the scale of the disaster are displayed. In the area for entering the congestion status, for example, buttons indicating the degree of congestion such as “Danger”, “Strong”, “Normal”, “Slightly”, and an input box in which the range of congestion can be input. Is displayed. The user selects the type of disaster, the intensity of the disaster, and the degree of congestion, and inputs the scale of the disaster and the range of congestion. The surrounding situation information Pda indicating the contents input by the surrounding situation input means 280 is used by the evacuation route searching means 260.

  The evacuation route searching means 260 determines the optimum refuge / evacuation route for the user based on the GPS information Gda, the input contents by the user, and the significant information Mda transmitted from the server 10 and stored in the significant information storage means 250. Explore. More specifically, as shown in FIG. 9, the evacuation route searching means 260 includes GPS information Gda, personal situation information Ida, movement ability information Dda, surrounding situation information Pda, geographical statistical information Sda, congestion information Cda, route profile Pro. Based on the simulation result Sre, the optimum evacuation site / evacuation route for the user is searched using the 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 the 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 the user performs a search for an evacuation route by the evacuation route search means 260 at the time of a disaster, the display means 290 displays the search result Re of the evacuation site / evacuation route.

  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 function selection information Fda is given to the data selection / transmission means 170, and the GPS information Gda is given to the data selection / transmission means 170 and the geographical statistical information acquisition means 110, The operation information Ada is given to the congestion state determination unit 120.

  Based on the GPS information Gda sent from each mobile terminal device 20, the geographic 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 the point at a predetermined period in real time. One point may be configured by one position coordinate (minimum unit position coordinate) in the GPS information Gda, or one point may be configured by a plurality of position coordinates in the GPS information Gda. 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. 10 and the passing number data having a data format as shown in FIG. Note that the geographical statistical information acquisition unit 110 may determine 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 the 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 the position 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 of the user X at that time are described. (Current position) is predicted. A specific example of this prediction will be described with reference to FIG. Regarding the route shown in FIG. 12, for convenience of explanation, it is assumed that the time required for moving from point B to point C and the time required for moving from point B to 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 this case, if there are 10 users moving in the same way as user X, “9 out of 10 people are at point C at 10:30 and the other one is at 10:30. Is predicted to be at point D. By performing such prediction, the number distribution and the like at each time point is estimated based on information of a large number of users. Note that a 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. 13, 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 basic information Bda described later based on GPS information Gda transmitted from each mobile 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 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. 14 is an example of a data format of the congestion information Cda generated by the congestion state determination unit 120. As shown in FIG. 14, the congestion information Cda is composed of position data (start point and end point data) of each route and congestion degree 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 the motion / behavior of a person 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 degree of congestion may be expressed in a plurality of levels (for example, 5 levels), may be expressed as a 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 basic information Bda described later. That is, 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. 15, for example. 15, “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 basic information Bda described later to perform a simulation for predicting the congestion degree of each point / route when a disaster occurs. Execute 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. 16 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 basic information storage unit 150 stores basic information Bda necessary for searching for an evacuation route. The basic information Bda includes a map, road information, shelter information, and the like. FIG. 18 is a diagram illustrating an example of a data format of road information. As shown in FIG. 18, the road information is composed of position data of each road (start point and end point data), distance data from the start point to the end point, road width data, and the like. FIG. 19 is a diagram illustrating an example of a data format of shelter information. As shown in FIG. 19, the refuge information includes refuge location data, capacity data, doctor presence / absence data, food stocktaking data, and the like. The basic information storage unit 150 is realized by the auxiliary storage device 14 as hardware.

  The tourist information storage means 160 stores 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. Has been. 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 and tourism 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 basic information Bda. By the way, transmitting all information (all significant information Mda and all tourism information Kda) held by the server 10 to the mobile terminal device 20 means that the storage capacity of the mobile terminal device 20 or communication for data transmission is performed. It is not realistic considering time. Therefore, the data selection / transmission unit 170 includes a significant information selection unit 172 and a tourist information selection unit 174 so that only necessary information is transmitted from the server 10 for each portable terminal device 20. . 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 GPS information Gda sent from each mobile terminal device 20. The tourist information selection unit 174 selects only the tourist information Kda desired by the user based on the GPS information Gda and the function selection information Fda sent from each portable terminal device 20. The significant information Mda selected by the significant information selecting unit 172 and the tourist information Kda selected by the sightseeing information selecting unit 174 are transmitted to the portable terminal device 20 by the data selecting / transmitting unit 170.

<2. Second Embodiment>
In the first embodiment, the server 10 determines the degree of congestion based on the operation information Ada transmitted from the mobile terminal device 20. However, the present invention is not limited to this, and the degree of congestion may be obtained based on the number of mobile phone users in each evacuation area. Therefore, an embodiment in which the degree of congestion is obtained based on the information on the number of mobile phone users (data on the number of mobile phone users in the area of each base station) acquired from the server of the mobile phone base station. This will be described below as a second embodiment. Hereinafter, description of the same points as in the first embodiment will be omitted as appropriate.

<2.1 Overall configuration>
The overall configuration of the evacuation route providing system according to the present embodiment is the same as that of the first embodiment. That is, the evacuation route providing system is realized by the server 10 and the plurality of mobile terminal devices 20. In order to realize this evacuation route providing system, the sightseeing / evacuation guidance application 30 is installed in the mobile terminal device 20.

<2.2 Detailed configuration of evacuation route providing system>
FIG. 22 is a block diagram showing a detailed functional configuration of the evacuation route providing system in the present embodiment. The server 10 is provided with a shelter priority information generation unit 165 and a mobile phone user number information acquisition unit 180 in addition to the components in the first embodiment (see FIG. 5). Unlike the first embodiment, the mobile terminal device 20 is not provided with the operation information acquisition unit 220. Therefore, in the present embodiment, unlike the second embodiment, the user information Yda transmitted from the mobile terminal device 20 to the server 10 does not include the operation information Ada.

  First, regarding the components in the server 10, differences from the first embodiment will be described. In general, data of the number of mobile phone users in the area of the base station (mobile phone user number information) is held in each mobile phone base station server. In the present embodiment, the mobile phone user number information acquisition unit 180 acquires the mobile phone user number information Tda held in the server of the mobile phone base station in real time. The mobile phone user number information Tda is given to the congestion state determination means 120, the shelter priority information generation means 165, and the data selection / transmission means 170.

  The congestion state determination unit 120 generates congestion information Cda based on the mobile phone user number information Tda and the basic information Bda. In general, the evacuation area and the area of the mobile phone base station have the same granularity (minimum unit size). Therefore, in the congestion state determination unit 120 in this embodiment, data indicating the degree of congestion for each evacuation area. Is generated as the congestion information Cda.

  The shelter priority information generating unit 165 generates the shelter priority information Hda based on the mobile phone user number information Tda and the basic information Bda. The refuge priority information Hda is “refuge priority” in order to prevent users exceeding the capacity from being guided to each refuge in consideration of the number of people in each refuge and the distribution of people in each refuge area. It is information indicating "degree". Specifically, the refuge priority information generation means 165 predicts the actual number of people in each evacuation area based on the mobile phone user number information Tda, and each refuge obtained from the predicted number of people and the basic information Bda. Compare with the capacity. Then, the priority of each evacuation site is determined so that users exceeding the capacity cannot be guided to each evacuation site. For example, assume that one evacuation site exists in each of two adjacent evacuation areas. Specifically, it is assumed that “evacuation center A” exists in “evacuation area A” and “evacuation area B” exists in “evacuation area B”. Here, if the capacity of the evacuation site A is 100 and the capacity of the evacuation site B is 80, if the estimated number of people in the evacuation area A is 60 and the estimated number of people in the evacuation area B is 100, The priority of the evacuation site A is increased so that the user in the evacuation area B is guided to the evacuation site A. The shelter priority information Hda thus generated is stored in the basic information storage unit 150 as one of the basic information Bda.

  The mobile phone user number information Tda given to the data selection / transmission means 170 is transmitted to the mobile terminal device 20 as one of the significant information Mda. The shelter priority information Hda stored in the basic information storage unit 150 is also transmitted to the mobile terminal device 20 as one of the significant information Mda by the data selection / transmission unit 170. As for the shelter priority information Hda, the data in the format stored in the basic information storage unit 150 may be transmitted to the mobile terminal device 20 as it is, or stored in the basic information storage unit 150. Data obtained by processing the data according to the position of the mobile terminal device 20 may be transmitted to the mobile terminal device 20.

  Next, regarding the components in the mobile terminal device 20, differences from the first embodiment will be described. The significant information Mda stored in the significant information storage unit 250 includes shelter priority information Hda in addition to the information in the first embodiment. The evacuation route searching means 260 determines the optimum refuge / evacuation route for the user based on the GPS information Gda, the input contents by the user, and the significant information Mda transmitted from the server 10 and stored in the significant information storage means 250. Explore. At that time, the evacuation destination as the guidance destination is determined based on the above-described refuge priority information Hda. Specifically, based on the refuge priority information Hda, the order of evacuation center candidates to be presented to the user as a guidance destination is determined.

That is, in this embodiment, the operation information Ada is not acquired by the operation information acquisition unit 220 (see FIG. 5). Accordingly, the operation information Ada is not included in the user information Yda transmitted to the server 10 by the user information transmitting unit 230 in step S130.

  In step S160, the significant information Mda transmitted from the server 10 is received. In step S170, the significant information Mda is stored in the significant information storage unit 250 (flash ROM 22 or RAM 23). The significant information Mda includes shelter priority information Hda in addition to the information in the first embodiment.

<2.3.2 Server processing>
In step S200, the user information Yda transmitted from the mobile terminal device 20 is received. The user information Yda does not include operation information Ada. After the tourist information Kda is transmitted to the mobile terminal device 20 in step S220, the mobile phone user number information acquisition unit 180 acquires the mobile phone user number information Tda held in the server of the mobile phone base station. (Step S225).

  In step S240, the congestion state determination unit 120 generates congestion information Cda based on the basic information Bda and the mobile phone user number information Tda acquired in step S225. After the simulation for predicting the degree of congestion at each point / route when a disaster occurs in step S260, the basic information Bda and the mobile phone user number information Tda are obtained by the shelter priority information generation unit 165. Based on this, the refuge priority information Hda is generated (step S265). Thereafter, significant information Mda is transmitted to the mobile terminal device 20 in step S270. The significant information Mda includes shelter priority information Hda in addition to the information in the first embodiment.

  In the present embodiment, the mobile phone user number information acquisition step is realized by step S225, and the shelter priority information generation step is realized by step S265. In FIG. 23, for convenience of explanation, step S225 is provided between step S220 and step 230. However, the processing of step S225 (processing for acquiring mobile phone user number information Tda) is performed sequentially (in real time). Done.

<2.4 Processing in the event of a disaster>
The flow of processing when a disaster occurs is the same as in the first embodiment (see FIG. 21). However, in the present embodiment, as described above, the refuge priority information Hda is transmitted to the portable terminal device 20 as one of the significant information Mda. The guide shelter is determined based on the degree information Hda.

<2.5 Effect>
According to this embodiment, in addition to the same effects as those of the first embodiment, the following effects can be obtained. In the present embodiment, when searching for evacuation shelters and evacuation routes in each mobile terminal device 20, the evacuation center for guiding the user is determined in consideration of the evacuation center priority information Hda. For this reason, even if there are more people in a certain evacuation area than the number of people in the evacuation area, by allocating the evacuation destination as a guide based on the degree of congestion, etc. Evacuation destinations are distributed to shelters in the surrounding evacuation area. This makes it possible to search for evacuation shelters and evacuation routes so that all users are accommodated in the evacuation shelters. In addition, the shelter priority order information Hda is generated based on the mobile phone user number information Tda acquired in real time. Searching for evacuation shelters and evacuation routes is performed in consideration. Furthermore, by using the evacuation center priority information Hda, it is possible to search for evacuation sites and evacuation routes with a small amount of calculation in each mobile terminal device 20.

  Incidentally, in the first embodiment, the congestion information Cda is generated based on the operation information Ada transmitted from the mobile terminal device 20, but in the present embodiment, the congestion information Cda is acquired from the server of the mobile phone base station. The congestion information Cda is generated based on the mobile phone user number information Tda. In this regard, with respect to data obtained from the mobile terminal device 20, there is a possibility that a sufficient number of data for grasping the degree of congestion of the entire evacuation area cannot be obtained. Moreover, although the information of local congestion degree is obtained from the data obtained from the portable terminal device 20, it is conceivable that the accuracy is insufficient for the entire evacuation area. In this regard, the server of the mobile phone base station holds a sufficient number of data to grasp the congestion level of the entire evacuation area. Therefore, according to the present embodiment, it is possible to search for a shelter / evacuation route while taking into consideration the degree of congestion of the entire evacuation area.

<2.6 Modification>
In the first embodiment, the congestion information Cda is generated based on the operation information Ada, and in the second embodiment, the congestion information Cda is generated based on the mobile phone user number information Tda. In this regard, the congestion information Cda generated based on the operation information Ada and the congestion information Cda generated based on the mobile phone user number information Tda may be used in combination. This makes it possible to search for shelters and evacuation routes using both local congestion level information such as the congestion level for each route and congestion level information for the entire evacuation area. Improves.
