As shown in FIG. 16, first, as a process of step S <b> 21, the traffic information providing unit 122 transmits the transmission terminal 10 (transmission associated with the acceleration information based on the acceleration information stored in the acceleration information database 114. It is determined whether or not the vehicle on which the terminal 10 of the terminal ID is mounted is suddenly stopped. Specifically, the traffic information providing unit 122 determines that the vehicle on which the transmission terminal 10 is mounted is suddenly stopped when the absolute value of acceleration is greater than the sudden stop determination threshold. Here, the sudden stop determination threshold value is a preset value. The sudden stop determination threshold is set, for example, experimentally, empirically, or theoretically. When the traffic information providing unit 122 determines that the vehicle on which the transmission terminal 10 is mounted is stopped suddenly, the traffic information providing unit 122 proceeds to the process of step S21.

  As the process of step S22, the traffic information providing unit 122 uses the other transmission terminal 10 (the transmission terminal 10 having the transmission terminal ID associated with the acceleration information) based on the acceleration information stored in the acceleration information database 114. ) For all, it is determined whether or not the vehicle (other vehicle) on which the transmission terminal 10 is mounted is stopped suddenly. Here, the other transmission terminal 10 is a transmission terminal 10 that is different from the transmission terminal 10 that has been determined that the vehicle has suddenly stopped in the process of step S21, and is determined based on the transmission terminal ID, for example. The Specifically, when the absolute value of the acceleration associated with the other transmission terminal 10 is larger than the sudden stop determination threshold, the traffic information providing unit 122 is mounted with the transmission terminal 10. It is determined that the vehicle is suddenly stopped. When the traffic information providing unit 122 determines that the vehicle on which the other transmission terminal 10 is mounted is suddenly stopped, the traffic information providing unit 122 proceeds to the process of step S23.

Specifically, the traffic information providing unit 122 refers to the acceleration information database 114 and acquires the acceleration acquisition time associated with the acceleration information. In addition, when there are a plurality of other transmission terminals 10 that are determined to be suddenly stopped in the process of step S22, the process of step S23 is performed for all of the plurality of suddenly stopped vehicles for the plurality of transmission terminals 10. Judge with. Specifically, the traffic information providing unit 122 determines the sudden stop time of the vehicle that has been determined to have been suddenly stopped in the process of step S21 and the sudden stop of the other vehicle that has been determined to have been suddenly stopped in the process of step S22. When the time interval with the stop time is less than or equal to the traffic accident determination threshold, it is determined that the times are close. Here, the traffic accident determination threshold value is a preset value. The traffic accident determination threshold value is set experimentally, empirically, or theoretically, for example. For example, the traffic accident determination threshold is 2 seconds.

  The traffic information providing unit 122 determines that the sudden stop time of the vehicle determined to be suddenly stopped in the process of step S21 is close to the sudden stop time of the other vehicle determined to be suddenly stopped in the process of step S22. If so, the process proceeds to step S24. On the other hand, if not, the traffic information providing unit 122 ends the traffic information providing process.

  As the process of step S24, the traffic information providing unit 122 determines whether or not the same receiving terminal 50 has detected a plurality of vehicles determined to have a sudden stop time in the process of step S23. Specifically, the traffic information providing unit 122 refers to the acceleration information database 114 and receives the receiving terminal ID (of the transmitting terminal 10) associated with the transmitting terminal ID of the transmitting terminal 10 mounted on each vehicle. If the receiving terminal ID is the same, it is determined that the same receiving terminal 50 has detected. The traffic information providing unit 122 proceeds to the process of step S25 when determining that the plurality of vehicles determined to have the sudden stop time near in the process of step S23 are detected by the same receiving terminal 50. On the other hand, if not, the traffic information providing unit 122 ends the traffic information providing process.

  For example, in the case of the acceleration information database 114 shown in FIG. 10, the traffic information providing unit 122 performs the processing in steps S <b> 21 to S <b> 24 described above, based on the acceleration and the acquisition time, and the transmission terminal ID = a and the transmission terminal ID. = B is identified, and the receiving terminal 50 with the receiving terminal ID = A is detected.

  As the processing of step S25, the traffic information providing unit 122 refers to the receiving terminal registration information database 113 and determines that the same receiving terminal 50 has detected in the processing of step S24, the receiving terminal of the receiving terminal 50 concerned. The position information of the receiving terminal 50 associated with the ID is acquired.

  As the process of step S26, the traffic information providing unit 122 refers to the contact information database 112, and the transmission terminal mounted on each vehicle determined to be detected by the same receiving terminal 50 in the process of step S24. Each contact address (email address) associated with the 10 sending terminal IDs is acquired. And the traffic information provision part 122 transmits the positional information on the receiving terminal 50 acquired by the process of step S25 to each acquired contact.

Remember.

(Operation, action, etc.)
FIG. 17 is a diagram illustrating a series of processes in the traffic support system 1. With reference to FIG. 17, an example of operations and actions in the traffic support system 1 will be described below.

  The receiving terminal 50 (for example, receiving terminal ID = A) is the transmitting terminal detection information transmitted by the first transmitting terminal 10 (for example, transmitting terminal ID = a) and the second transmitting terminal 10 (for example, transmitting terminal ID = b). Is received, the own receiving terminal ID (receiving terminal ID = A) is added and transmitted to the traffic information providing server 100.

  In the traffic information providing server 100, when the acceleration information management unit 121 receives the transmission terminal detection information from the reception terminal 50 by the acceleration information management process, the transmission terminal ID, the acceleration information, and the information included in the transmission terminal detection information are received. The receiving terminal ID is stored in the acceleration information database 114.

  And in the traffic information provision server 100, the traffic information provision part 122 performs a traffic information provision process. As a result, the traffic information providing unit 122 stops each vehicle (installed in the vehicle) when a plurality of vehicles are suddenly stopped and their sudden stop times are close and detected by the same receiving terminal 50. The position information is transmitted to each contact address associated with the transmitting terminal 10). That is, the traffic information providing unit 122 detects an accident as the movement status of one of the plurality of transmission terminals 10 based on the signals of the plurality of transmission terminals 10 received by the reception terminal 50, and detects the vehicle ( The position information is transmitted to each contact address associated with the transmission terminal 10) mounted on the vehicle.

  Here, when a plurality of vehicles stop suddenly and their sudden stop times are close and the same receiving terminal 50 detects these sudden stops, the receiving terminal 50 is within the receiving area (for example, the receiving area of 20 m). This means that a plurality of vehicles are suddenly stopped at the same time, and there is a high possibility that a plurality of vehicles are suddenly stopped due to a contact accident or the like. Therefore, when such a contact accident occurs, the traffic information providing unit 122 can contact the contact information associated with each vehicle with the position information of the receiving terminal 50 as the position information of the contact accident. It becomes like this.

(Effect in this embodiment)
(1) The traffic information providing server 100 detects a moving state of the transmission terminal 10 based on acceleration information that is a signal of the transmission terminal 10 acquired via the reception terminal 50, thereby providing a vehicle equipped with the transmission terminal 10. It is possible to detect the movement status of people and the like more accurately. For example, the traffic information providing server 100 that is the subject of the processing is not mounted on the vehicle, and its processing resources are not limited by the environment on the transmitting terminal 10 side, so that the vehicle provided with the transmitting terminal 10 by processing resources that are not limited, It is possible to detect the movement status of people and the like more accurately.

(2) The traffic information providing server 100 can more accurately detect the movement status of one transmitting terminal 10 by using signals from a plurality of transmitting terminals 10.
(3) The traffic information providing server 100 can output the position information of the receiving terminal 50 based on the situation relating to a car, bicycle, or human traffic accident.

(4) The traffic information providing server 100 can more easily detect the movement status of the transmission terminal 10 by using the position information or acceleration information of the transmission terminal 10.
(5) The traffic information providing server 100 can detect the movement status of the transmission terminal 10 by a simpler process such as comparing the acceleration of the transmission terminal 10 with a preset threshold value.

  In the description of the above-described embodiment, the traffic information providing server 100 configures a position information output device, for example. Moreover, the traffic information provision part 122 comprises a detection means and an output means, for example.

(Other examples of this embodiment)
As another example of the embodiment, the transmission terminal 10 may be attached to a bicycle or a person. Moreover, in the traffic support system 1, the transmission terminal 10 attached to a car, a bicycle, or a person may be mixed. Here, when the transmission terminal 10 is attached to a bicycle or a person, the traffic information providing server 100 naturally performs a process corresponding to that. For example, when the transmission terminal 10 is attached to a bicycle or a person, the traffic information providing server 100 determines the stop of the bicycle or the person using a threshold value for determining a sudden stop that is different from that for a car.

  As another example of the embodiment, the receiving terminal 50 is not limited to being fixedly installed, and may be mobile. In this case, the receiving terminal 50 attached to a car, a bicycle, or a person receives the transmitting terminal detection information from the transmitting terminal 10. In addition, the receiving terminal 50 has positioning means such as GPS (Global Positioning System), adds the position information of the own terminal to the transmitting terminal detection information, and transmits it to the traffic information providing server 100. And the traffic information provision server 100 manages the positional information on the receiving terminal 50 together with the transmitting terminal detection information.

  As another example of the embodiment, the traffic support system 1 may use the position information of the transmission terminal 10 as a signal of the transmission terminal 10. In this case, the transmitting terminal 10 detects its own position information by positioning means such as GPS. Then, the transmission terminal 10 transmits the detected position information by including it in the transmission terminal detection information. When the traffic information providing server 100 receives the calling terminal detection information via the receiving terminal 50, the traffic information providing server 100 stores the position information included in the calling terminal detection information in the database and based on the position information (change in position). The acceleration information is calculated, and the calculated acceleration information is stored in the acceleration information database 114 as shown in FIGS. At this time, for example, the acceleration acquisition time is the time when the calculation is performed, or the time when the transmission terminal 10 or the traffic information providing server 100 acquires the position information.

  As another example of the present embodiment, the traffic information providing unit 122 may simply output a telephone number as a contact address on the display unit connected to the traffic information providing server 100. Further, the traffic information providing unit 122 may simply output the position information of the receiving terminal 50 acquired by the process of step S25 to the display unit. Through these processes, the company that manages the traffic information providing server 100 verbally explains the location information output on the display unit to the contact number of the telephone number output on the display unit.

  As another example of the present embodiment, the receiving terminal 50 may have its own location information instead of the receiving terminal registration information database 113. In this case, when receiving the transmission terminal detection information from the transmission terminal 10, the reception terminal 50 includes the location information in the transmission terminal detection information and transmits the transmission terminal detection information to the traffic information providing server 100. And the traffic information provision part 122 acquires the positional information on the receiving terminal 50 based on the receiving terminal detection information received in the process of step S25.

  As another example of the present embodiment, the receiving terminal 50 may be communicable with another receiving terminal 50 through another communication line (for example, a 920 MHz band LoRa wireless communication line). For example, in this case, a plurality of receiving terminals 50 are grouped so that they can communicate with each other, and any of the receiving terminals 50 communicates with the traffic information providing server 100 via the Internet line 200 as a representative. As a result, the receiving terminal 50 transmits the transmission terminal detection information detected by itself to the traffic information providing server 100 via the representative receiving terminal 50.

  Further, in the present embodiment, based on the signal of the transmission terminal received by the reception terminal, a detection step of detecting the movement status of the transmission terminal, and on the reception terminal based on the movement status detected in the detection step An output step for outputting the associated position information is realized.
