Description

  The present invention generally relates to an evacuation guidance system using a portable terminal having a wireless communication function.

  In recent years, an evacuation guidance system using a mobile phone having a GPS (Global Positioning Systems) function when a disaster occurs has been proposed (see, for example, Patent Document 1). This system provides the evacuation route from the current location to the evacuation site on the display of the mobile phone based on the location information from the GPS mobile phone of the residents.

In addition, a vehicle navigation system has been developed that presents a route from a current position of a vehicle to a destination using position information obtained by a GPS function. There has been proposed a system that accumulates position information of a moving body such as a vehicle and analyzes a trend such as an activity state of the moving body by using the vehicle navigation (see, for example, Patent Document 2).

  With the evacuation guidance system as described above, residents can evacuate quickly to a designated evacuation site while viewing the evacuation route displayed on the mobile phone display.

  By the way, in the evacuation route set on the system, there is a possibility that there are places (roads and vacant spaces) that are not accessible due to road construction, for example. In such a case, since the residents cannot pass along the route that is being guided, they may turn back or make a detour, resulting in problems such as delaying evacuation.

  In order to eliminate such inconvenience, it is necessary to update the evacuation route for guidance on the system side. However, in practice, it is not easy including the timing of updating. For example, by combining the evacuation guidance system and the system that accumulates the location information of the moving body as described above and analyzes the movement status of the moving body, etc., the trend of residents who are likely to delay evacuation is analyzed. A system that can provide an optimal evacuation route in real time is desirable, but it is not easy to implement.

  Therefore, an object of the present invention is to provide an evacuation guidance system that can appropriately change an evacuation route for guiding to an evacuation site.

  An aspect of the present invention is that, in a system that provides a terminal with map information indicating an evacuation route to an evacuation site, a location where the evacuation route cannot pass is generated by monitoring the movement of the terminal. The evacuation guidance system includes a function of changing an evacuation route according to an inconvenient situation.

  An evacuation guidance system according to an aspect of the present invention includes: a receiving unit that receives position information that is transmitted from a terminal having a wireless communication function and indicates a current position of the terminal; and a current state of the terminal based on the position information. Means for determining an evacuation route from a position to an evacuation site, means for generating map information including information indicating the evacuation route, means for transmitting the map information to the terminal, and based on movement of the terminal And changing means for determining whether or not the evacuation route is appropriate and changing the evacuation route when the evacuation route is inappropriate.

  The evacuation guidance system of the present invention can provide an evacuation guidance system that can automatically change the evacuation route when it is determined that the evacuation route provided to the terminal is inappropriate.

  Embodiments of the present invention will be described below with reference to the drawings.

(System configuration)
FIG. 1 is a block diagram illustrating a configuration of an evacuation guidance system according to the present embodiment.

  As shown in FIG. 1, the system includes a terminal 10 having a wireless communication function, a server 11, a database 12, and a wireless base station 30. The terminal 10 is a mobile phone, for example, and has a so-called GPS function and Web browser function, and generates and transmits position information 100P indicating the current position based on radio waves from the GPS satellite 20. Further, the terminal 10 has a built-in display device for displaying map information (GIS information) 100G provided from the server 11 described later on the display 10A.

  The server 11 has a wireless communication function for performing wireless communication with the terminal 10 via the wireless base station 30, transmits the map information 100G to the terminal 10 by the wireless communication, and receives the position information 100P from the terminal 10. To do.

  The server 11 executes evacuation guidance processing described later using software prepared in advance and information stored in the database 12. The database 12 stores map information necessary for evacuation guidance, position information transmitted from the terminal 10, and the like.

(Evacuation guidance processing)
Hereinafter, the evacuation guidance process according to the present embodiment will be described with reference to the flowcharts of FIGS. 2 and 3 together with FIG. 1.

  First, roughly speaking, when a disaster occurs, a resident makes an inquiry to the server 11 by wireless communication from a terminal (mobile phone) 10 that is carried. Here, the server 11 corresponds to a computer system of a system center managed by, for example, a local public entity. The server 11 provides an evacuation route to a preset evacuation site to the terminal 10 that has made an inquiry (access).

  The resident moves to the designated evacuation site while confirming the evacuation route provided from the server 11 on the display 10A of the terminal 10.

  Hereinafter, the processing procedure of the server 11 will be specifically described with reference to the flowchart of FIG.

  Upon receiving access from the terminal 10, the server 11 receives the position information 100P transmitted from the terminal 10 by wireless communication (step S1). The server 11 recognizes the current position of the terminal 10 based on the position information 100P. Furthermore, the server 11 determines an evacuation route (evacuation route) from the current position to the designated evacuation site using information stored in the database 12 (map information and information indicating the designated evacuation site) (step) S2).

  Next, the server 11 uses the information stored in the database 12 to generate map information 100G including the determined evacuation route (route from the current position to the evacuation site) (step S3). The server 11 transmits the generated map information 100G to the terminal 10 by wireless communication (step S4).

  The terminal 10 receives the map information 100G transmitted from the server 11, and generates a map image including the evacuation route using the map information 100G. The terminal 10 displays the generated map image on the display 10A. The map image indicates an evacuation route (evacuation route) from the current position of the terminal 10 to the evacuation site.

  A resident carrying the terminal 10 can move from the current position to the evacuation site while confirming the evacuation route displayed on the display 10A.

  Here, the server 11 continuously receives the position information 100P from the terminal 10 that provided the map information 100G, and monitors the movement route of the terminal 10 (step S5). That is, the server 11 records the route on which the terminal 10 is actually moving in association with the map information stored in the database 12.

  When the travel route of the terminal 10 matches the evacuation location of the evacuation route provided, the server 11 stops the monitoring process and proceeds to the next process (evacuation guidance process of another terminal) (NO in step S6). .

(Evacuation route change processing)
On the other hand, if the route of the terminal 10 is different from the evacuation route provided, the server 11 proceeds to the evacuation route change process (YES in step S6). By monitoring the movement route of the terminal 10, the server 11 specifies and records a portion (location or road) where the actual movement route and the provided evacuation route do not match before reaching the evacuation site from the current position. To do.

  Here, the server 11 repeatedly executes the processes from the above-described steps S1 to S5, thereby monitoring the movement routes of the plurality of terminals 10 with respect to the same evacuation route, thereby causing the inconsistent portion (location or road). Are stored in the database 12.

  Then, the server 11 determines that there is an inaccessible place (or road) in the provided evacuation route based on the monitoring results of the movement routes of the plurality of terminals 10 (accumulation of inconsistent portions with respect to the same evacuation route). Determination is made, and the place where the passage is impossible is specified on the map information (step S7).

  Next, the server 11 changes the previously set evacuation route to a new evacuation route up to the same evacuation location including another accessible location excluding the specified inaccessible location (step S8). The new evacuation route is stored in the database 12 in place of the previously set evacuation route (step S9).

  By such an evacuation route change process, the server 11 performs map information including a new evacuation route 220 corresponding to the same evacuation place with respect to the terminal 10 by the evacuation guidance process (steps S1 to S4) as described above. 100G is provided.

  Therefore, as shown in FIG. 2, when the generated map image 200 is displayed on the display 10A, the terminal 10 displays a new evacuation route (evacuation route) 220 from the current position 210 to the evacuation site. In this case, the previous evacuation route is a route including the inaccessible place 230. By the evacuation route change processing, the server 11 provides a new evacuation route 220 from the current position 210 to the same evacuation site, except for the inaccessible place 230.

  Thereby, the resident carrying the terminal 10 moves to the evacuation site while avoiding the inaccessible place 230 from the current position 210 while checking the new evacuation route 220 displayed on the display 10A. be able to.

  As described above, according to the system of the present embodiment, for example, when a disaster occurs, the evacuation route from the current position of the terminal 10 to the evacuation site can be provided to the terminal 10 carried by the residents. Further, it is possible to determine the presence of an inaccessible place (or road) included in the provided evacuation route from the actual travel route of the terminal 10 and to set a new evacuation route to avoid the inaccessible place. it can.

  In other words, it is possible to provide an evacuation route to a designated evacuation location and to reliably update the evacuation route to avoid an inaccessible location. Therefore, since the evacuation route including the inaccessible place can be automatically updated, it is possible to reduce the situation that the inhabitants in the middle of evacuation turn back or make a detour when moving to the evacuation place.

  In short, according to the present embodiment, it is possible to determine the suitability of an evacuation route from the movement status of a terminal that moves based on the provided evacuation route, and to update an inappropriate evacuation route to an appropriate evacuation route at all times. Become.

  In addition, although the terminal 10 assumed portable terminals, such as a mobile telephone which a resident carries, it is not restricted to this, The navigation for vehicles mounted in the vehicle which has a GPS function may be sufficient.

(Other embodiments)
In the present embodiment, the server 11 determines the presence of an inaccessible place (or road) included in the provided evacuation route from the actual travel route of the terminal 10 and newly avoids the inaccessible place. A change process for setting an evacuation route is executed.

  As another embodiment, the server 11 may measure the travel time from the actual travel route of the terminal 10 to the evacuation site, and execute a change process for changing the evacuation route based on the measurement result. That is, the server 11 does not determine the presence of an inaccessible place (or road) included in the provided evacuation route, but makes the travel time from a specific position included in the evacuation route to the evacuation place the shortest time. You may perform the process which updates an evacuation route so that it may become.

  In the evacuation route change processing of this embodiment, when a new road is created after setting the evacuation route previously, a new evacuation that includes the new road and can reduce the travel time to the evacuation site A route can be provided.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
