  And the risk level acquisition part 134 acquires the place information which shows the place corresponding to the position of the pedestrian which the said one terminal position information shows using the one terminal position information and map information. Since a method and procedure for acquiring location information using one piece of location information (here, terminal location information) and map information are known, detailed description thereof is omitted. Then, the risk level acquisition unit 134 acquires a score corresponding to a location condition that the acquired location information matches from a correspondence table held in advance.

  For example, the risk level acquisition unit 134 may acquire the risk level using attribute information. The attribute information is attribute information that three or more pieces of terminal position specifying information used for acquiring one terminal position information usually have. Moreover, the said attribute information is information which shows the attribute of the pedestrian from whom risk level is acquired normally. In this case, the risk level acquisition unit 134 holds, for example, a correspondence table between attribute conditions and risk levels in advance. An attribute condition is a condition related to attribute information. It can also be said that the attribute condition is a condition related to the attribute. The attribute conditions include, for example, that the pedestrian is an elderly person, that the pedestrian is a child, and that the pedestrian is a woman. Then, the risk level acquisition unit 134 acquires, from the terminal location specification information, the attribute information that the three or more pieces of terminal location specification information used for acquiring one terminal location information have in common. Then, the risk level acquisition unit 134 acquires the risk level corresponding to the attribute condition that matches the attribute information from the correspondence table.

  In the correspondence table between the attribute condition and the risk level, the risk level may be a score that is a basis for calculating the risk level. In this case, the risk level acquisition unit 134 calculates the risk level by substituting the acquired score into a calculation formula for calculating the risk level.

And the 2nd judgment part 136 acquires the 2nd judgment result information which is the information which shows the result of the said judgment, for example. The second determination result information indicates, for example, that the pedestrian enters the roadway or that the pedestrian does not enter the roadway.

  For example, the second determination unit 136 acquires the traveling direction of the pedestrian using the history of two or more terminal position information. And the 2nd judgment part 136 is the road which exists in the advancing direction acquired using the newest terminal position information and map information, and the distance from the nearest from the latest terminal position information shows is the road. Calculate the distance. When the acquired traveling direction is toward the roadway and the calculated distance is short enough to satisfy a predetermined condition, the second determination unit 136 determines that the pedestrian has entered the roadway. Judge that. And the 2nd judgment part 136 acquires the 2nd judgment result information which shows that a pedestrian enters into a roadway. Otherwise, the second determination unit 136 acquires second determination result information indicating that the pedestrian does not enter the roadway.

  The second determination result information acquired by the second determination unit 136 is, for example, held in advance by the second determination unit 136. The second determination result information may be stored in a predetermined storage area, for example.

Here, it is assumed that the first determination unit 135 determines that the position indicated by the terminal position information A is a position on the roadway. Then, the first determination unit 135 obtains, for the terminal position information A, first determination result information “roadway” indicating that the position indicated by the terminal position information A is a position on the roadway.

  Next, the first determination unit 135 determines whether the position indicated by the terminal position information B is a position on the roadway using the map information and the terminal position information B. Here, it is assumed that the first determination unit 135 determines that the position indicated by the terminal position information B is not a position on the roadway. Then, the first determination unit 135 acquires, for the terminal position information B, first determination result information “non-roadway” indicating that the position indicated by the terminal position information B is not a position on the roadway.

  Next, the output unit 138 outputs the terminal position information A and the terminal position information B in a size corresponding to the first determination result information corresponding to each terminal position information. At this time, for example, the output unit 138 uses the icon used for outputting the terminal position information when the first determination result information is “roadway” rather than when the first determination result information is “non-roadway”. Terminal position information is output so as to increase. At this time, the output unit 138 outputs the terminal position information together with the map information.

In this example, an example will be described in which the terminal position information is output in a mode corresponding to the second determination result information. In this example, it is assumed that the terminal location information shown in FIG. 10 is stored in a predetermined storage area of the car navigation system.

  First, the second determination unit 136 associates the terminal identification information “202.124.48.24” with “ID = 011” terminal location information, “ID = 013” terminal location information, “ The terminal location information of “ID = 014” is acquired. Then, the second determination unit 136 uses the three terminal position information to determine whether or not the pedestrian carrying the smartphone identified by the terminal identification information “202.124.48.24” enters the roadway. Determine whether. Here, it is assumed that the second determination unit 136 determines that the smartphone enters the roadway. Then, the second determination unit 136 indicates to the terminal identification information “202.124.48.24” that the pedestrian who has the smartphone identified by the terminal identification information enters the roadway. Judgment result information “approach” is acquired.

  Next, the second determination unit 136 associates the terminal identification information “202.127.176.15” with the terminal location information “ID = 012” in FIG. 10, the terminal location information “ID = 015”, Terminal location information of “ID = 016” is acquired. Then, the second determination unit 136 uses the three terminal position information to determine whether or not a pedestrian carrying a smartphone identified by the terminal identification information “202.127.176.15” enters the roadway. Determine whether. Here, it is assumed that the second determination unit 136 determines that the smartphone does not enter the roadway. Then, the second determination unit 136 indicates, to the terminal identification information “202.127.176.15”, that the pedestrian carrying the smartphone identified by the terminal identification information does not enter the roadway. Judgment result information “non-entry” is acquired.

  Next, the output unit 138 adds the terminal location information acquired by the terminal location information acquisition unit 133 to the terminal identification information “202.124.48.24” and the terminal identification information “202.127.176.15”. On the other hand, the terminal position information acquired by the terminal position information acquisition unit 133 is output in a color corresponding to the second determination result information corresponding to each terminal position information. At this time, the output unit 138, for example, when the second determination result information is “entry”, the icon used for outputting the terminal position information is white, and when the second determination result information is “non-entry”, The terminal position information is output so that the icon used to output the terminal position information is black. At this time, the output unit 138 outputs the terminal position information together with the map information. An example of the output is, for example, FIG.

(Example 5)
In this example, an example will be described in which terminal location information is output in a manner corresponding to third determination result information.

  First, it is assumed that the terminal location information acquisition unit 133 acquires terminal location information for each of four different pieces of terminal identification information. Each of the four terminal position information is referred to as terminal position information A, terminal position information B, terminal position information C, and terminal position information D.

  Next, the 3rd determination part 137 acquires attribute information from the terminal position specific information used for acquisition of said each 4 terminal position information. The attribute information is information indicating an age group. The attribute information is attribute information corresponding to each of the four pieces of terminal position information. Here, the attribute information corresponding to the terminal position information A is attribute information A, the attribute information corresponding to the terminal position information B is attribute information B, the attribute information corresponding to the terminal position information C is attribute information C, the terminal position The attribute information corresponding to the information D is defined as attribute information D. Further, it is assumed that the attribute information A is “old man”, the attribute information B is “adult”, the attribute information C is “adult”, and the attribute information D is “child”.

  Next, the third determination unit 137 determines whether the attribute indicated by the attribute information is an elderly person or a child. Then, the third determination unit 137 determines that the attribute information A is an old man or a child, and acquires third determination result information “old child”. The third determination result information indicates that the attribute indicated by the attribute information is an elderly person or a child. In addition, the third determination unit 137 determines that the attribute information B is not an elderly person or a child, and acquires third determination result information “non-aged child”. The third determination result information indicates that the attribute indicated by the attribute information is not an elderly person or a child. In addition, the third determination unit 137 determines that the attribute information C is not an elderly person or a child, and acquires third determination result information “non-aged child”. Further, the third determination unit 137 determines that the attribute information D is an old man or a child, and acquires third determination result information “old child”.

  Next, the third determination unit 137 converts the four pieces of terminal position information of terminal position information A, terminal position information B, terminal position information C, and terminal position information D into third determination result information corresponding to each terminal position information. Output in a shape according to. At this time, the output unit 138, for example, if the third determination result information is “old child”, the icon used for outputting the terminal position information is a star, and the third determination result information is “non-old child”. The terminal position information is output so that an icon used for outputting the terminal position information has a round shape. At this time, the output unit 138 outputs the terminal position information together with the map information. An example of the output is, for example, FIG.

  As described above, according to the pedestrian detection system 1 according to the present embodiment, it is possible to detect a pedestrian existing around the current position and notify the user of the presence of the pedestrian. Thereby, for example, the user who is driving the mobile body can grasp the presence of a pedestrian that cannot be grasped from his current position, and also drives while paying attention to the movement of the pedestrian. be able to.

  Further, for example, when information indicating the current position of the terminal device 11 is directly transmitted to the in-vehicle device 13, it is necessary to acquire information indicating the current position in the terminal device 11, and power consumption in the terminal device 11 (The battery will be depleted faster). On the other hand, according to the pedestrian detection system 1 according to the present embodiment, the terminal device 11 simply transmits information indicating the strength of the radio wave to the relay device 12 in response to reception of the radio wave from the relay device 12. The power consumption in the terminal device 11 can be suppressed (preventing the battery from being depleted quickly). Specifically, when the terminal device 11 is a smartphone, when the information indicating the current position is directly transmitted to the in-vehicle device 13, it is necessary to turn on a so-called GPS function, but the pedestrian detection system according to the present embodiment According to 1, the vehicle-mounted device 13 can specify the position of the user who owns the smartphone without turning on the GPS function.

  In the present embodiment, relay device 12 may include relay terminal location information acquisition unit 124. The relay terminal position information acquisition unit 124 acquires terminal position information. In this case, the relay receiving unit 122 receives the terminal location specifying information from, for example, the other two or more relay devices 12. The relay terminal location information acquisition unit 124 then receives the terminal information received from the terminal device 11, the relay location information stored in the relay location information storage unit 121, and two or more received from the other two or more relay devices 12. The terminal position information is acquired using the terminal position specifying information. Note that the processing and operation performed by the relay terminal location information acquisition unit 124 are the same as the processing and operation performed by the terminal location information acquisition unit 133. Further, the relay transmission unit 123 transmits the terminal location information acquired by the relay terminal location information acquisition unit 124 to the in-vehicle device 13.

  Further, when the relay device 12 acquires terminal location information, the in-vehicle device 13 does not include the terminal location information acquisition unit 133. Then, the reception unit 132 receives terminal position information from the relay device 12. Then, the output unit 138 outputs the terminal location information received by the receiving unit 132.

  FIG. 14 is a block diagram when the relay device 12 includes the relay terminal location information acquisition unit 124 and the in-vehicle device 13 does not include the terminal location information acquisition unit 133.

  In addition, the relay transmission unit 123 normally transmits radio waves within a range in which the distance from the relay device 12 satisfies a predetermined condition. In other words, the radio waves transmitted by the relay transmission unit 123 can be normally received by the terminal device 11 that is close enough to satisfy a predetermined distance to the relay device 12. That is, when the terminal device 11 is normally located in a so-called communication area of the relay device 12, the terminal device 11 receives the radio wave transmitted by the relay device 12. Then, the terminal device 11 transmits terminal information having radio wave intensity information indicating the intensity of the radio wave to the relay device 12.

  In addition, the relay transmission unit 123 normally transmits the terminal location specifying information within a range in which the distance from the relay device 12 satisfies a predetermined condition. In other words, the terminal location specifying information transmitted by the relay transmission unit 123 can be normally received by the in-vehicle device 13 that is close enough to satisfy a predetermined distance to the relay device 12. That is, when the in-vehicle device 13 is normally located within a so-called communication area of the relay device 12, the on-vehicle device 13 receives the terminal position information transmitted by the relay device 12. Thereby, the vehicle-mounted apparatus 13 can detect and output the pedestrian who exists in the range with which the distance from self satisfy | fills the conditions satisfy | filled beforehand, for example. The in-vehicle device 13 may receive the terminal position information transmitted by the relay device 12 even when the distance to the relay device 12 is far enough to satisfy a predetermined condition. Thereby, the vehicle-mounted apparatus 13 can detect and output the pedestrian who exists in the range far enough so that the distance from self satisfy | fills the conditions determined beforehand, for example.
