[Figure 6] This is a flowchart explaining the control method related to this disclosure. [Modes for carrying out the invention]

[0013] The configuration example of the control device 100 for preventing traffic accidents described herein will be explained below with reference to the figures. The control device 100 shown in Figure 1 is installed in the roadside and / or bicycle lane around an intersection and comprises at least a detection unit 101 and an output unit 102.

[0014] Figure 2 shows an example of the installation of the control device 100 of this disclosure. The control device 100 is installed in the roadside area 121 and / or the bicycle lane 122 of the intersection 120. In the example shown in Figure 2, the control device 100 uses a notification unit 103 installed in the bicycle lane 122 to notify a vehicle 110 traveling through the intersection 120 of the presence of a cyclist 111 traveling in the bicycle lane 122. The notification unit 103 exemplified in Figure 2 is installed in the bicycle lane 122 of the intersection 120, but is not limited to this location and may be installed at any location in the intersection 120 or in the roadside area 121.

[0015] The detection unit 101 detects terminals 112 carried by persons 111 traveling in the roadside area 121 and / or the bicycle lane 122, such as pedestrians, cyclists, and electric scooter riders.

[0016] The processing of the detection unit 101 will be explained using the sequence diagram in Figure 3. The detection unit 101 is equipped with a first wireless communication means 104 and communicates with a terminal 112 carried by a person 111 passing through the roadside 121 and / or bicycle lane 122. The first wireless communication means 104 detects the presence of the person 111 by receiving a response from the terminal 112.

[0017] The detection unit 101 detects the terminal 112 by performing broadcast by the first wireless communication means 104 and receiving a response from the terminal 112. Specifically, the terminal 112 is a smartphone, and the first wireless communication means 104 is a short-range wireless communication of Bluetooth (registered trademark).

[0018] The control device 100 is an advertiser of the first wireless communication means 104, and periodically transmits an advertisement packet (S10).

[0019] The detection unit 101 detects a person 111 passing through the roadside strip (路側帯)121 and / or the bicycle lane 122 when the detection unit 101 receives a scan request transmitted by an initiator built in the terminal 112 (S20).

[0020] Optionally, the control device 100 may notify the terminal 112 that a vehicle 110 is approaching the intersection 120 (S30). By doing so, the presence of the vehicle 110 can be notified to the passerby (通行する者) 111 carrying the terminal 112.

[0021] Upon receiving that the detection unit 101 has detected a person 111 passing through the roadside strip 121 and / or the bicycle lane 122, the output unit 10^{2} outputs a signal for notifying the driver of a vehicle 110 traveling around the intersection 120 of the presence of the passerby 111 to the notification unit 103. If there is no scan request from the terminal 112, the output unit 102 does not output to the notification unit 103.

[0022] The notification unit 103 includes a light source, and notifies the driver of a vehicle 110 traveling around the intersection 120 of the presence of the passerby 111 by lighting and / or flashing the light source.

[0023] Since the control device 100 of the present disclosure particularly focuses on alerting to prevent卷入 accidents during left turns, it is preferable that the installation location of the notification unit 103 has good visibility from the vehicle 110 traveling in the left turn lane at the intersection 120.<00001​ The notification unit 103 may not only notify the driver of the vehicle 110 using the light source described above, but may also communicate with the wireless communication means 113 of the vehicle 110 by providing a second wireless communication means 105 to notify the driver of the vehicle 110. Figure 4 is a diagram illustrating the configuration of the control system 10 of the present disclosure. The control system 10 comprises a control device 100 and a notification unit 103. Figure 5 is a flowchart illustrating the control method of the control system 10 of the present disclosure.

[0025] The control device 100 detects a terminal 112 carried by a person 111 traveling on the roadside 121 and / or bicycle lane 122 in the detection unit 101 (S101).

[0026] When the detection unit 101 detects a terminal 112 carried by a person 111 traveling on the roadside 121 and / or bicycle lane 122, the output unit 102 outputs a predetermined output (S102). The predetermined output is a signal to notify the drivers of vehicles 110 traveling around the intersection 120 of the presence of the person 111.

[0027] As the output unit 102 outputs a signal to notify the driver of a vehicle 110 traveling around the intersection 120 of the presence of a person 111, the notification unit 103 notifies the driver of the vehicle 110 (S103). The notification is made by lighting and / or flashing the light source provided by the notification unit 103, as described above. This notification method is suitable because it is easily visible to the vehicle 110 even in poor visibility conditions such as rain or at night.

[0028] The notification unit 103 is not limited to the illumination and / or flashing of a light source; it may also use a display panel or means for outputting an alarm sound, but it is preferable that the notification means does not cause light pollution or noise.

[0029] Furthermore, an example of a notification method in which the notification unit 103 is equipped with a second wireless communication means 105 and communicates with the wireless communication means 113 equipped with the vehicle 110 is a wireless communication means compliant with VICS (Vehicle Information and Communication System) (registered trademark). In this case, the second wireless communication means 105 is, for example, a VICS transmitter.

[0030] Figure 6 is a flowchart illustrating in detail the control method of the control system 10 of this disclosure. When the control device 100 starts operating, the detection unit 101 starts the detection operation described above (S110). In the above example, the detection unit 101 continues to transmit advertisement packets periodically, for example, at a predetermined interval, and when the terminal 112 is detected, the detection unit 101 ends the detection operation.

[0031] When terminal 112 is detected, the predetermined output described above is made to notify the driver of vehicle 110 of the presence of a person 111 passing by (S120).

[0032] The conditions for terminating the notification are preferably when there are no more people 111 traveling on the roadside 121 and / or the bicycle lane 122, that is, when the people 111 have moved a predetermined distance away from the intersection 120. Therefore, the detection unit 101 updates the status information of the people 111 traveling on the roadside 121 and / or the bicycle lane 122 (S130).

[0033] The status information is updated by sending an advertisement packet and detecting terminal 112, similar to the detection operation of terminal 112 (S140). Contrary to the detection operation in S110, if terminal 112 is not detected, that is, if there are no longer any persons 111 traveling on the roadside 121 and / or bicycle lane 122, a notification termination signal is sent from the output unit 102 to the notification unit 103 (S150). If terminal 112 is detected, there are still persons 111 traveling on the roadside 121 and / or bicycle lane 122, so the notification continues.

[0034] In this way, it becomes possible to provide a control device, control system, control method, and program that can alert vehicles traveling around an intersection when there are people traveling on the roadside and / or bicycle lane around the intersection.
