Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the transport induction system及beauty traffic guiding method according to the present invention will be described in detail.

<Concept of traffic guidance system according to Example 1>
First, the concept of the traffic guidance system according to the first embodiment will be described. FIG. 1 is an explanatory diagram for explaining the concept of the traffic guidance system according to the first embodiment. Here, road construction is carried out in the illustrated construction section of a road consisting of two lanes with one lane on each side, and construction signals 10a and 10b (hereinafter collectively referred to as "construction signals 10") are performed at both ends of this construction section. Will be shown when installing. Although the upper lane of the road shown in FIG. 1 is defined as the up lane and the lower lane as the down lane, other terms may be used.

The construction signal 10 shown in FIG. 1 is a signal that presents information relating to the right of way of a vehicle passing through the construction section. Similar to the traffic light installed at the intersection, the construction signal 10 has a green circle display (hereinafter, simply referred to as "green signal") or a red circle display (hereinafter, simply referred to as "red light"). If it is a green traffic light, it means that the vehicle can pass through the construction section, and if it is a red traffic light, it means that the vehicle cannot pass. As a result, the vehicle trying to pass through the construction section will pass through the construction section according to the green signal presented on the construction signal 10, or will stop at the stop line in front of the construction section according to the red light. For convenience of explanation, the case where the yellow circle is displayed is omitted here, but in the case of the yellow circle display (yellow traffic light), the vehicle in the standby state cannot safely stop at the stop line. As a condition, pass through the construction section while paying attention to the surrounding traffic.

In addition, two traffic guides are assigned to this construction section. Here, a main person in charge of traffic guidance (main traffic guide) A and a sub-person in charge (deputy traffic guide) B who assists the main traffic guide A are assigned. The reason why the main traffic guide A and the sub traffic guide B are arranged in this way is that if each traffic guide controls the construction signal 10 independently, it causes confusion at the construction site. .. Therefore, here, as a general rule, only the main traffic guide A controls the construction signal 10. Further, it is assumed that the main traffic guide A possesses the main operation terminal 20 shown in the figure, and the sub-traffic guide B possesses the sub-operation terminal 30 shown in the figure.

Here, as a conventional technique, there is a technique for switching the mode of the construction signal 10 to the automatic lighting mode or the manual lighting mode by using the operation terminal 20, but even if this conventional technique is used, the traffic guide is on site. The current state of the construction signal 10 cannot be recognized unless the construction signal 10 of the above is visually recognized. In addition, the traffic guide will visually check the congestion situation at the site and switch the mode. For example, when the construction section is long, one traffic guide should grasp the congestion situation in the up lane and the down lane. I can't. Therefore, in the first embodiment, such a problem is solved, and the main traffic guide A and the sub-traffic guide B (hereinafter, may be collectively referred to as “traffic guide”) are the main operation terminal 20 and the sub-operation, respectively. When a terminal 30 (hereinafter, may be collectively referred to as an "operation terminal") is possessed, the construction signal 10 can be smoothly and efficiently controlled by using the main operation terminal 20 and the sub-operation terminal 30. ..

Specifically, as shown in FIG. 1, the display operation unit 21 of the main operation terminal 20 displays the signal status (red signal, green signal, elapsed time) of the construction signal 10 and the periphery of the construction section. Displays the traffic congestion status (vehicle congestion status in the up lane, vehicle congestion status in the down lane, congestion status of pedestrians, etc.). Although not shown here, the display operation unit 31 of the sub-operation terminal 30 also performs the same display. As a result, the main traffic guide A and the sub-traffic guide B can grasp the signal state of the construction signal 10 and the congestion situation around the construction section with reference to the main operation terminal 20 and the sub-operation terminal 30. ..

Further, when the traffic jam setting button displayed on the display operation unit 21 of the main operation terminal 20 is pressed, the main traffic guide A can set the traffic jam situation, and the traffic jam situation is notified to the sub-operation terminal 30. Will be done. Similarly, when the congestion setting button displayed on the display operation unit 31 of the sub-operation terminal 30 is pressed, the sub-traffic guide B can set the congestion status, and this congestion status is transmitted to the main operation terminal 20. You will be notified. As a result, each traffic guide can grasp the traffic congestion information around the construction section by using each operation terminal. In addition, when each traffic guide sets the traffic jam information, he / she can select from items such as "no traffic jam", "normal", "slightly traffic jam", and "long traffic jam".

Further, when the signal setting button displayed on the display operation unit 21 of the main operation terminal 20 is pressed, the display time of the red signal and the green signal of the construction signal 10 can be set, and the setting notification button is displayed. When the pressing operation is performed, the setting data is notified to the construction signal 10 and the sub-operation terminal 30. In principle, the main operation terminal 20 can set the construction signal 10, but the sub-operation terminal 30 cannot set the construction signal 10. If the construction signal 10 can be set independently of the main operation terminal 20 and the sub operation terminal 30, the construction signal 10 may be unexpectedly changed in setting, which may cause confusion for the traffic guide. Because there is.

However, if it is desired to temporarily set the construction signal 10 from the sub-operation terminal 30, the construction signal 10 must be temporarily permitted (pressing the temporary permission button) by the main operation terminal 20. Can be set. For example, this is because a personal injury accident occurred in the construction section, and the deputy traffic guide B who knew this fact had to suddenly change both the up lane and the down lane to a red light.

In addition, when the main traffic guide A is busy responding to an accident and cannot control the construction signal 10, he / she can press the proxy request button displayed on the display operation unit 21 of the main operation terminal 20. The sub-operation terminal 30 can be requested to act on your behalf. Further, when the accident response by the main traffic guide A is completed and the situation is such that the original role can be fulfilled, the return button displayed on the display operation unit 21 of the main operation terminal 20 is pressed. As a result, the return notification is sent to the sub-operation terminal 30, and the traffic guidance control can be performed by the main operation terminal 20.

As described above, according to the first embodiment, the construction signal 10 installed in the construction section using the main operation terminal 20 and the sub-operation terminal 30 possessed by the main traffic guide A and the sub-traffic guide B, respectively. Is configured to display and control the signal status of the construction signal 10 and the congestion status around the construction section on the display operation units 21 and 31 of the main operation terminal 20 and the sub operation terminal 30. The guide A and the sub-traffic guide B can confirm the situation at the site by using the main operation terminal 20 and the sub-operation terminal 30.

Further, by operating the temporary permission button, the traffic jam setting button, the proxy request button, and the return button provided in the display operation unit 21 of the main operation terminal 20, the construction signal 10 can be efficiently linked with the sub operation terminal 30. Can be controlled.

<Exterior configuration of construction signal 10>
Next, the external configuration of the construction signal 10 shown in FIG. 1 will be described. FIG. 2 is a diagram showing an external configuration of the construction signal 10 shown in FIG. As shown in the figure, the construction signal 10 has a display unit 11, a control unit 12, and the like.

The display unit 11 is composed of a display device such as a liquid crystal panel. The green signal and the red signal are alternately displayed and controlled on the display unit 11, and when the green signal is displayed and controlled, a message such as "Please slow down" is displayed. Further, in the case of a green signal, a graph or the like showing the remaining time of the green signal can also be displayed.

<Structure of control unit 12>
Next, the internal configuration of the control unit 12 shown in FIG. 2 will be described. FIG. 3 is a functional block diagram showing the internal configuration of the control unit 12 shown in FIG. As shown in the figure, the construction signal 10 is provided with a control unit 12, a communication I / F unit 13, and a storage unit 14. The communication I / F unit 13 is a communication interface unit for performing wireless communication between the main operation terminal 20 and the sub operation terminal 30 by using a well-known technology such as wireless LAN or LTE (Long Term Evolution) communication. ..

The authentication processing unit 12a is a processing unit that authenticates whether or not the operation terminal is a device having access authority to the construction signal 10 when an access request is received from the operation terminal. Specifically, when each operation terminal accesses the construction signal 10, the access information includes the identification information. Then, this identification information is compared with the identification information included in the authentication data 14b to authenticate whether or not the user has a legitimate access authority.

For example, when the operation terminal of the access request source is the main operation terminal 20, it is authenticated as having a legitimate access authority, and when the operation terminal of the access request source is the sub operation terminal 30, a legitimate access is performed. Authenticate as not authorized. However, even if the operation terminal of the access request source is the sub-operation terminal 30, if the permission by the main operation terminal 20 is included, it is authenticated that the user has a legitimate access authority. Even if an attempt is made to control the construction signal 10 from a fake operation terminal possessed by a malicious third party, the access request is rejected by such an authentication process. Therefore, it is possible to prevent unauthorized signal control by a malicious third party.

The display control unit 12b is a control unit that displays and controls a green signal, a red signal, and a message with respect to the display unit 11 based on the setting data 14a. A timer is used to switch between the red signal and the green signal.
