The sound output unit 16C is for converting the electrical signals from the control units 10B and 10C into sound and outputting the sound, and includes, for example, a speaker.

  The danger information management program 11A-1 is for causing the control unit 10A to execute a series of procedures for managing the danger information database 11A-3. The map information database 11A-2 is configured by associating map information M for pedestrians with a name (for example, a1) assigned to each intersection on the map information M (FIG. 9 to FIG. 9). 12). The risk information database 11A-3 includes, for example, a risk level 39 for each combination of the risk time zone 25 and the risk target person 27 in a section 38 (for example, section a8-a10) obtained by dividing the road on the map information M for each intersection. Are stored in association with each other (see FIGS. 5 and 9 to 12). In FIG. 5, the combinations of the danger time zone 23 and the danger target person 27 having the same risk level 39 in the a8-a10 section, the a6-a10 section, and the a7-a11 section are collectively shown for convenience. . The risk information database 11A-3 further includes a coefficient 25c for each day section 25a, a coefficient 25d for each time section 25b, a coefficient 27a for each risk target person 27, and a risk degree A for each risk factor 29. Stored in association.

  The terminal program 11B-1 receives the input of the dangerous position information 21, the dangerous type 23, the dangerous time zone 25, the dangerous target person 27, and the risk factor 29 (see FIG. 7), and sends the information to the route guidance device 1A. This is for causing the control unit 10B to execute a series of procedures for the transmission of. The terminal program 11C-1 receives input of the personal information 31, the departure point 33, the destination 35, and the danger type 23 (see FIG. 8) of the guardian 1C-1, and searches the route guidance device 1A for the route. This is for causing the control unit 10B to execute a series of procedures for request, reception of the route information 37 sent from the route guidance device 1A, and output of the route information 37. Details of these series of procedures will be described in detail later in “Series of Procedures in Danger Information Collection Phase P1” and “Series of Procedures in Route Information Provision Phase P2”.

  Here, the dangerous position information 21 is a place where it is perceived as dangerous sensuously or a place where an incident actually occurred. For example, the reporter 1B-1 selects the name of the location from the location list 22 or makes a GPS search request to the terminal device 1B instead of using the location list 22, for example. The location of the GPS receiver 13B is acquired or a map search request is made instead of using the location list 22, and input to the terminal device 1B by selecting the location from the displayed pedestrian map information M Information.

  Further, the danger type 23 is a kind of danger that can be perceived sensuously or an event that has actually occurred. This risk type 22 is obtained, for example, by selecting from the risk type list 24 what kind of danger the sensation feels or what actually happened is. The danger type list 24 includes, for example, a traffic accident 23A, a chikan 23B, a take-away 23C, and a robber 23D.

  The dangerous time zone 25 is a dangerous time zone in the section 38 closest to the location. This dangerous time zone 25 is obtained, for example, by selecting in what time zone the zone 38 closest to the location is considered dangerous from the dangerous time zone list 26. The dangerous time zone list 26 includes, for example, a weekday list 26A having a total of two types of weekday sections 25a, weekdays and weekends and holidays, and a total of AM7 to AM9, AM9 to PM3, PM3 to PM5, PM5 to PM7, and PM7 to AM7. A time division list 26B having five types of time divisions 25b is included (see FIGS. 5B and 5C). Coefficients 25c are respectively assigned to weekdays and weekends and holidays included in the day-of-week classification list 26A. For example, 1 is assigned to “weekdays” and 2 is assigned to “Saturdays, Sundays, and holidays”. Similarly, a coefficient 25d is assigned to each element included in the time division list 26B. For example, 1 to 5 are assigned in the order of the list. The dangerous time zone 25 corresponds to the coefficient 26C (for example, the coefficient A applied to weekdays) corresponding to the day-of-week section 25a selected from the day-of-week section list 26A and the time section 25b selected from the time-section list 26B. (For example, A3) that is combined with a coefficient (for example, coefficient 3 assigned to PM3 to PM5).

  The danger target person 27 is a person who is likely to be exposed to danger in the time zone of the section 38 closest to the location. The risk target person 27 is obtained, for example, by selecting one or more persons who are likely to be exposed to the risk from the risk target person list 28. The risk target person list 28 includes, for example, a kindergarten / elementary / middle school (male) 27A, a kindergarten / elementary / middle school (female) 27B, a high school / college student (male) 27C, a high school / college student (female) 27D, a general (male) 27E, A total of seven types of people, general (female) 27F and elderly 27G, are included (see FIG. 6A). Each element included in the risk target person list 28 is assigned a coefficient 27a. For example, 1 to 7 are assigned in the order of the list.

  The risk factor 29 is an event that is sensuously felt dangerous in the section 38 closest to the location or that has actually occurred. The risk factor 29 is obtained by, for example, selecting one or more from the risk factor list 30 to feel sensuously dangerous or to actually happen. The risk factor list 30 includes, for example, 29A with low traffic, 29B with a poor view, 29C with no traffic light at the intersection, 29D without a sidewalk, 29E with a heavy traffic, 29E with a thick forest, and darkness in the daytime It includes a total of 12 items: 29G, 29H with a pervert, 29J with a traffic accident, 29K with a chinkan case, 29L with a takeaway case, and 29M with a robbery case (Fig. 5 ( C)). Each element (risk factor 29) included in the risk factor list 30 is assigned a risk A for each risk type 23. For example, for a traffic accident 23A, 0, 3, 3 in the order of the list. , 3, 3, 0, 1, 0, 10, 0, 0, 0 are assigned, respectively, and for Chikan 23B, 3, 1, 0, 0, 0, 3, 3, 6 in the order of the list. , 0, 10, 0, 0 are assigned, and 3,3,0,0,0,1,5,6,0,0,10,0 are assigned to the removal 23C in the order of the list. 3, 3, 0, 0, 0, 3, 3, 6, 0, 0, 0, 10 are assigned to the robber 23D in the order of the list. Here, the sum of the risk A of each of the traffic accidents 23A, the kankan 23B, the take away 23C and the robber 23D listed above for each risk factor 29 is the risk factor 29 when the risk type 23 is not distinguished. Since the risk level A, that is, the overall risk level A of each risk factor 29 is represented, this risk level A is classified separately as the risk level A of the non-classified 23E. 9, 10, 3, 3, 3, 7, 11, 18, 10, 10, 10, and 10 are assigned to the non-classified 23E in the order of the risk factor list 30, respectively.

  The personal information 31 is information representing the social classification of the guardian 1C-1, for example. The personal information 31 is obtained, for example, by selecting one social classification of the guardian 1C-1 from the personal information list 32. The social classifications here are, for example, kindergarten / elementary / middle school (male) 27A, kindergarten / elementary / middle school (female) 27B, high school / college student (male) 27C, high school / college student (female) 27D, general (male) 27E, general (female) 27F, elderly person 27G, and the like are classified according to the same items as those included in the above-described risk target person list 28, and these elements are included in the personal information list 32. A coefficient is assigned to each element included in the personal information list 32. For example, 1 to 7 are assigned in the order of the list.

  The starting point 33 is the current location of the guardian 1C-1 or the route information of the safest route (the safest route) for the guardian 1C-1 when the guardian 1C-1 is going to the destination 35 from now on. The point farthest from the destination 35 that requires 37. For example, instead of using the departure place list 34, the guardian 1C-1 selects the name of the departure place 33 from the departure place list 34 or makes a GPS search request to the mobile terminal device 1C. Go to automatically acquire the location of the GPS receiver 13C, or make a map search request instead of using the departure place list 34, and select the location from the displayed pedestrian map information M Is information input to the mobile terminal device 1C.

  The destination 35 is a destination that the guardian 1C-1 needs to go from now on. The destination 35 is the same as the departure point 33. For example, the guardian 1C-1 selects the name of the destination 35 from the destination list 36 or makes a map search request instead of using the destination list 36. This is information input to the mobile terminal device 1C by selecting a location from the displayed pedestrian map information M.

  The route information 37 is, for example, a plurality of routes (first route 37A, second route 37B, third route 37C, fourth route 37D) from the starting point 33 to the destination 35 as illustrated in FIGS. ) And at least one route selected from among the selected routes, and a safety rank (described later) of the selected route.

  Here, when determining which of the plurality of routes is the safest route (the safest route), the risk of the route is taken into consideration. The risk of one route is calculated, for example, by the total value of the risk 39 of each section 38 included in the route (first calculation method) or the risk 39 of each section 38 included in the route. Calculated based on the maximum value (second calculation method). The risk level 39 used when calculating the risk level of each section 38 is the sum of the risk levels A corresponding to one or a plurality of risk factors 29 existing in a section 38, and is classified for each risk type 23. (See FIG. 5A). Therefore, the magnitude of the risk 39 in each section 38 differs depending on the danger type 23.

  The rank of the safety level included in the route information 37 is, for example, 100 multiplied by a value obtained by dividing the risk level of the safest route by the sum of the risk levels 39 of all the sections 38 included in the map information M. Value is the safest range (for example, 0 to less than 0.3), semi-safe range (for example, 0.3 to less than 5), intermediate safe range (for example, 5 to less than 10), semi-danger range (for example, 10 to less than 50) , Which is included in the most dangerous range (for example, 50 or more and 100 or less), and indicates a relatively objective safety level of the safest route. For example, when the risk level of the safest route is 3 and the sum of the risk levels 39 of all sections 38 included in the map information M is 600, the risk level of the safest route is included in the map information M. Since the value obtained by multiplying the value obtained by dividing the risk level 39 of all the sections 38 by the sum of 100 is 0.5, it can be seen that the safety rank of the safest route is the quasi-safe range. As described above, the rank of safety level has a function of complementing an insufficient part of the safest route that only knows the relative safety level.

  Here, the initial value of the risk level 39 may be 0 until the risk factor 29 is reported to the set of sections 38, the risk time zone 25, and the risk target person 27 from the reporter 1B-1. One or a plurality of risk factors 29 assumed for the set of sections 38, the risk time zone 25, and the risk target person 27 are prepared in advance and correspond to the prepared one or more risk factors 29. It is good also as a total value of risk A to do.

  Further, the value of the risk level 39 is updated by, for example, the following first addition method or second addition method. In the first addition method, the dangerous position information 21, the dangerous time zone 25, and the dangerous subject 27 that overlap with the set of sections 38, the dangerous time zone 25, and the dangerous subject person 27 are transferred to the terminal device of the reporter 1B-1. When received from 1B, a value obtained by summing the risk A corresponding to one or more risk factors 29 received from the terminal device 1B of the reporter 1B-1 for each risk type 23 is already stored. The risk level 39 is added for each risk type 23.

  An example of calculation when this first addition method is used, for example, the location corresponding to the a8-a10 section as the dangerous position information 21, A3 as the dangerous time zone 25 at the location, and the dangerous object at the location 2 for the person 27 and “29A with low traffic” and “B foresight 29B” as the risk factors 29 at the location are respectively received from the terminal device 1B of the reporter 1B-1 in the section a8-a10. The value of the risk 39 already stored for each risk type 23 in relation to the combination of the risk time zone 25 (A3) and the risk target person 27 (2) ((traffic accident 23A, power supply 23B, take-away 23C, robbery 23D , Unclassified 23E) = (10, 10, 12, 12, 44)), the risk A corresponding to the risk factor 29 is set for each risk type 23. Value ((traffic accident 23A, trenchless 23B, kidnapping 23C, robbery 23D, non-classified 23E) = (3,4,6,6,19)) is added to each. As a result, the value of the risk level 39 for each risk type 23 becomes ((traffic accident 23A, chikan 23B, take away 23C, robbery 23D, unclassified 23E) = (13, 14, 18, 18, 63)). . By correcting the value of the risk level 39 in this way, the risk level 39 for the section 38, the risk time zone 25, and the risk target person 27 that many people think is not a problem at any time. It becomes possible to bring the size close to the degree of danger that people who frequently use the section 38 and the danger time zone 25 (dangerous person 27) feel on their skin.

  In the second addition method, a value (new value) obtained by summing the risk A corresponding to one or more risk factors 29 received from the terminal device 1B of the reporter 1B-1 for each risk type 23 has already been obtained. It is determined whether or not the value of the risk level 39 (existing value) for each stored risk type 23 is greater than the existing value. The value is stored, and when the new value becomes equal to or less than the existing value, the value of the risk level 39 is left as the existing value.

  An example of calculation when this second addition method is used, for example, the location corresponding to the a8-a10 section as the dangerous position information 21, A3 as the dangerous time zone 25 at that location, and the dangerous object at that location 2 for the person 27 and “29A with low traffic” and “B foresight 29B” as the risk factors 29 at the location are respectively received from the terminal device 1B of the reporter 1B-1 in the section a8-a10. The existing value of the risk 39 already stored for each risk type 23 in association with the combination of the risk time zone 25 (A3) and the risk target person 27 (2) is ((traffic accident 23A, power supply 23B, take away 23C, robbery 23D, unclassified 23E) = (10, 10, 12, 12, 44)), and the risk A corresponding to the risk factor 29 is a risk species. The new value is the sum for each 23, it is ((traffic accident 23A, trenchless 23B, kidnapping 23C, robbery 23D, non-classified 23E) = (3,4,6,6,19)). Accordingly, since the new value is smaller than the existing value, the value of the risk level 39 remains the existing value.

  At this time, in the same section, danger time zone 25, and risk target person 27, one or a plurality of risk factors 29 such that the new value is equal to or less than the existing value are repeatedly received from the terminal device 1B of the reporter 1B-1. When it does, it can be understood that many people think that it is not wrong when an incident or accident occurs, so the value of the risk 39 is corrected according to the number of times of repeated reception (danger information reception count 40) It is preferable to do. For example, the value of the risk level 39 may be increased by 1 each time it is repeatedly received, and the risk level is increased when the risk information reception count 40 is 1 to 5, as shown in FIG. The risk level B (= 3) is added to the value of 39, the risk level B (= 8) is added to the value of the risk level 39 in the case of 6 to 10, and the risk level 39 is dangerous in the case of 11 or more A degree B (= 15) may be added. By correcting the value of the risk level 39 in this way, the risk level 39 for the section 38, the risk time zone 25, and the risk target person 27 that many people think is not a problem at any time. It becomes possible to bring the size close to the degree of danger that people who frequently use the section 38 and the danger time zone 25 (dangerous person 27) feel on their skin.

  Hereinafter, the risk level of the unclassified 23E of each route illustrated in FIGS. 9 to 12 (first route 37A, second route 37B, third route 37C, and fourth route 37D) is shown. A calculation method using the first calculation method when the junior high school student (female) (= coefficient 2) and the dangerous time zone 25 is PM5 to PM7 (= coefficient A4) on weekdays will be described.

  First, the first route 37A passes through the a1-a2 section, the a2-a3 section, the a3-a6 section, the a6-a7 section, the a7-a11 section, and the a10-a11 section while going from the departure point 33 to the destination 35. It is a route that goes through. Here, as illustrated in FIG. 5A, it is assumed that the risk level 39 of the section a7-a11 is 31 among the above sections, but the risk level 39 of the other sections is 0. At this time, the degree of risk of the first route 37A becomes 31, for example, when the first calculation method is used.

  Next, the second route 37B goes through the a1-a2, the a2-a3, the a3-a6, the a6-a10, and the a10-a11 sections while going from the departure point 33 to the destination 35. It is a route. Here, as illustrated in FIG. 5A, it is assumed that the risk level 39 in the a6-a10 section among the above sections is 10, and the risk level 39 in the other sections is 0. At this time, the risk degree of the second route 37B becomes 10 when the first calculation method is used, for example.

  Next, the third route 37C passes through the a1-a2 section, the a1-a4 section, the a4-a8 section, the a8-a10 section, and the a10-a11 section while going from the departure point 33 to the destination 35. It is a route. Here, as illustrated in FIG. 5A, it is assumed that the risk level 39 of the section a8-a10 is 44 and the risk level 39 of the other sections is 0. At this time, the degree of risk of the third path 37C becomes 44 when the first calculation method is used, for example.

  Finally, in the fourth route 37D, while going from the departure point 33 to the destination 35, the a1-a2 section, the a1-a4 section, the a4-a8 section, the a8-a9 section, the a9-a10 section, and the a10-a11 section It is a route that goes through. Here, as illustrated in FIG. 5A, it is assumed that the degree of risk 39 is 0 in any of the above sections. At this time, the degree of risk of the fourth path 37D becomes 0 when the first calculation method is used, for example.

  From these results, it can be seen that the overall safest route when the child / elementary / junior high school student (female) goes from the departure point 33 to the destination 35 on weekdays PM5 to PM7 is the fourth route 37D with a zero risk. I understand.

  Subsequently, with reference to FIG. 13 and FIG. 14, an example of operations of the route guidance device 1A, the terminal device 1B, and the mobile terminal device 1C according to the present embodiment will be described.

  FIG. 13 shows an example of the flow of the danger information collection face P1 in which the danger level 39 is accumulated for each set of section 38, danger time zone 23, and danger target person 27 in the danger information database 11A-3. . FIG. 14 shows an example of the flow of the route information provision phase P2 for providing the safest route information 37 from the danger information database 11A-3.

  First, in the route guidance device 1A, when the risk information management program 11A-1 is started, the route guidance device 1A enters a state of waiting for communication with the terminal devices 1B and 1C. On the other hand, when the terminal program 11B-1 is started up in the terminal device 1B, it enters a waiting state for input of the dangerous position information 21, the dangerous type 23, the dangerous time zone 25, the dangerous subject 27, and the dangerous factor 29. On the other hand, when the terminal program 11C-1 is started up in the mobile terminal device 1C, it enters a state waiting for input of information (personal information 31, departure point 33, destination 35) necessary for searching for the safest route. In this way, preparations for operating the route guidance device 1A, the terminal device 1B, and the mobile terminal device 1C are completed.

(Danger Information Collection Phase P1)
The reporter 1B-1 uses the location list 21, the GPS search button 22A or the map search button 22B, the dangerous position information 21, the dangerous type list 23 using the dangerous type list 23, the day classification list 23A and the time classification. When a dangerous time zone 25 including a day of the week section 25a and a time section 25b is input using the list 26B, a dangerous person 27 is input using the dangerous person list 28, and a risk factor 29 is input using the dangerous person list 28 ( Input of information such as risk factor 29: Step S1), the terminal device 1B accepts it (Step S2). Subsequently, when the reporter 1B-1 presses the report button 41 (step S3), the terminal device 1B transmits information such as the input risk factor 29 to the route guidance device 1A (step S4).

  Thereafter, the route guidance device 1A receives information such as the risk factor 29 transmitted from the terminal device 1B (step S5). Then, the route guidance device 1A refers to the map information database 11A-2, finds a section 38 corresponding to the dangerous position information 21, and associates the dangerous time zone 25 and the dangerous target person 27 with the found section 38. . At this time, it is searched whether or not it has been previously reported to the section 38, the danger time zone 25, and the risk target person 27 that are the same as the associated section 38, the risk time period 25, and the risk target person 27, If no report has been made before, the risk information reception count 40 is set to 1, and the risk information reception count 40 is associated with the section 38, the risk time zone 25, and the risk target person 27, and the risk information database 11A- 3 is stored. On the other hand, if it has been previously reported to the associated section 38, the dangerous time zone 25 and the dangerous target person 27, the dangerous time period 25 and the dangerous target person 27, the dangerous time period 25 A value obtained by adding 1 to the risk information reception count 40 associated with the band 25 and the risk target person 27 is stored in the risk information database 11A-3 as the risk information reception count 40 (association: step S6).

  Next, the route guidance device 1 </ b> A obtains a risk level 39 by summing the risk levels A corresponding to the received one or more risk factors 29. Subsequently, it is determined whether the stored risk information reception count 40 corresponds to any region of 1 to 5, 6 to 10, 11 or more, and the number assigned to the corresponding region is determined as the risk level B. As a result, the risk level B is added to the previously calculated value of the risk level 39 to calculate a new risk level 39 in the section 38 (calculation of the risk level 39: step S7). At this time, if the newly calculated risk 39 (new value) is greater than the stored risk 39 (existing value), the newly determined risk 39 is used as the risk information database 11A-. 3 and conversely, when the risk level 39 obtained by the calculation is smaller than the risk level 39 that is already stored, the value of the risk level 39 that is already stored is left as it is (the risk information 2 Save: Step S8).

  By repeating such a procedure, the danger information database 11A-3 as shown in FIG. 5A is constructed.

(Route information provision phase P2)
The guardian 1C-1 uses the personal information list 32, the personal information 31, the departure place list 34, the GPS search 34A or the map search 34B, the departure place 33, and the destination list 36 or the map search 36B. When the destination 35 is entered and the danger type 23 is entered using the danger type list 24 (input of information necessary for the route search request: step S10), the mobile terminal device 1C accepts it (step S11). . Subsequently, when the person requiring protection 1C-1 presses the route search button 42 (step S12), the mobile terminal device 1C transmits the route search request to the route guidance device 1A together with the received information (step S13).

  Thereafter, the route guidance device 1A receives information necessary for requesting the safest route information 37 transmitted from the mobile terminal device 1C and accepts a route search request (step S14). Then, the route guidance device 1A reads map information M including the departure point 33 and the destination 35 from the map information database 11A-2, and then extracts a plurality of possible routes from the route from the departure point 33 to the destination 35. To do. Then, the route guidance device 1A calculates the risk level 39 of each extracted route, and provides the safest route for the risk target person 27 corresponding to the personal information 31 and the information associated with the safest route in the risk information database. Extract from 11A-3 (step S15). Here, if the guardian 1C-1 selects the non-classification 23E as the risk type 23, the route having the smallest risk 39 corresponding to the risk A of the non-classification 23E is extracted and specified. If the risk type 23 (traffic accident 23A or the like) is selected, a route having the smallest risk level 39 corresponding to the risk level A of the specific risk type 23 is extracted. Subsequently, the route guidance device 1A transmits route information 37 including the selected safest route and accompanying information to the mobile terminal device 1C (step S16).

  In step S16, the route having the smallest risk level 39 corresponding to the risk level A for each risk type (traffic accident 23A,...) Is extracted, and the risk level corresponding to the risk level A of unclassified 23E. Each safest route from which the route 39 is extracted is arranged together with accompanying information, and the route having the smallest risk level 39 corresponding to the type of danger 23 selected by the guardian 1C-1 is displayed at the top of the list. It is also possible to transmit the information arranged in the mobile terminal device 1C as the route information 37.

  Thereafter, the mobile terminal device 1C receives the route information 37 transmitted from the route guidance device 1A (step S17). Then, the mobile terminal device 1C receives the GPS signal from the GPS satellite by the GPS receiving unit 13B and acquires the current position information (step S18). Based on the acquired current position information, the route information 37 is displayed on the display unit 14C, and information necessary to guide the guardian 1C-1 to the destination 35 is output from the voice output unit 16C. (Step S19). For example, when the guardian 1C-1 is using the mobile terminal device 1C while walking, the route guidance device 1A has transmitted the current position so that the current position is always located at the center of the display unit 14C. The route information 37 is displayed while being corrected as needed. When the route information 37 includes a plurality of safest routes, the route guidance device 1A displays the list on the display unit 14C and selects one of them as the guardian 1C-1 in need. When the guardian 1C-1 selects one safest route from the list, the selected safest route is displayed on the display unit 14C. In this way, the person requiring protection 1C-1 is guided to the destination 35 via the safest route.

  As described above, in the route guidance device 1A and the risk information management method of the present embodiment, the personal information 31 of the guardian 1C-1 requiring protection of the mobile terminal device 1C transmitted from the mobile terminal device 1C, the departure place 33 and the destination 35 are received, the received personal information 31, the departure place 33 and the destination 35, the map information M included in the map information database 11A-2, and the danger information 2 included in the danger information database 11A-3. Based on the above, route information 37 of the safest route for the guardian 1C-1 is selected from a plurality of routes from the departure point 33 to the destination 35, and the selected route information 37 is the guardian who needs protection. 1C-1 is transmitted to the mobile terminal device 1C. Thereby, the guardian 1C-1 can grasp in advance the safest path for the guardian 1C-1 among the plurality of routes to the destination 35.

  Further, in the mobile terminal device 1C or the terminal program 11C-1 according to the present embodiment, when the personal information 31, the departure place 33, and the destination 35 of the guardian 1C-1 are input, the input personal information 31 The starting point 35 and the destination 37 are transmitted to the route guidance device 1A. Thereafter, when the safest route information 37 for the guardian 1C-1 among the plurality of routes from the departure point 33 to the destination 35 transmitted from the route guidance device 1A is received, the GPS signal from the GPS satellite 1D is received. Is received, position information is acquired, and the safest route information 37 is output based on the acquired position information. Thereby, the guardian 1C-1 can grasp in advance the safest route for the guardian 1C-1 among the plurality of routes to the destination 37.

  As a result, there is no possibility that the guardian 1C-1 such as a young child or a young woman will step into a dangerous place for a while, so the possibility of getting involved in a crime or accident can be reduced. As a result, it is possible to protect the guardian 1C-1 such as a young child or a young woman from crimes and accidents.

  In addition, by adopting the danger information management system of this embodiment, it is possible to reduce the number of crimes and accidents involved, so it is possible to realize a safe country that can be proud of in the world. Thus, the danger information management system of this embodiment can greatly contribute to the creation of a safe country.

  While the present invention has been described with reference to the above embodiment, the present invention is not limited to this, and various modifications can be made. For example, in the above embodiment, the safest route information 37 is provided to the person requiring protection 1C-1, but the user of the mobile terminal device 1C, for example, tries to protect the person requiring protection 1C-1. If it is a person who wants to protect the guardian 1C-1, the route information 37 of the route with the highest degree of danger (most dangerous route) is provided to the person who wants to protect the guardian 1C-1. You may do it. As a result, even if the person requiring protection 1C-1 erroneously views the safest route information 37 or does not use this system, he / she accidentally steps into a dangerous place. Since the person who wants to protect the person 1C-1 can flexibly and intensively patrol the road with the highest degree of danger according to the danger target person and the dangerous time zone, such person is protected from crimes and accidents. It becomes possible.

  In the above embodiment, the GPS receivers 13B and 13C are detected using the GPS satellite 1D. However, the present invention is not limited to this, for example, using a base station such as a mobile phone. The position of the mobile terminal device 1C may be detected.
