<First embodiment>
In the first embodiment, a case will be described in which an antenna of a roadside communication device is installed at a position corresponding to a display device called an information board. Examples of the case include a case where the antenna of the roadside communication device is directly attached to the display device and a case where the display device and the antenna of the roadside communication device are attached to a gantry provided across the road.

  FIG. 1 is a block diagram illustrating an example of a schematic configuration of the variable fee management system. As shown in FIG. 1, the variable fee management system includes a variable fee determination device 1, a display information creation device 2, a traffic record management device 3, an evidence recording unit 4, a plurality of display devices (information boards) 5, a plurality of roadside communications. A device 6 and a plurality of terminal devices 7 are provided.

  The variable fare determination device 1, the display information creation device 2, the traffic record management device 3, the evidence recording unit 4, and the terminal device 7 are devices on the central side, and the installation locations are not particularly limited. The plurality of display devices 5 and the plurality of roadside communication devices 6 are roadside devices, and are installed on or along the road. Each display device 5 is installed at a position where the driver of the vehicle can visually observe the vehicle while driving. Each roadside communication device 6 is installed at a position corresponding to the display device 5.

  First, the variable fee determining device 1 will be described. The variable fee determination device 1 includes a control unit 11, a storage unit 12, and a communication unit 13.

  The control unit 11 of the variable fare determination device 1 predicts the degree of congestion and the required time from the traffic jam information and the traffic jam prediction of each route in each time zone. Then, based on the congestion degree and the required time of each route in each time zone, taking into account the effect of congestion mitigation caused by changing the toll, the toll of each route in each time zone (hereinafter referred to as “variable fee”) Is determined. Here, the “variable fee” may be determined automatically by the system or manually registered in the system based on the judgment of the operator.

  Then, the control unit 11 determines a time zone earlier by a predetermined time as a display period related to the variable fee with respect to the application period of the variable fee, and sets the display device 5 to be displayed among the plurality of display devices 5. decide.

  Here, the reason for setting the variable charge display period to be a time zone earlier than the application period by a predetermined time is that the driver can select a route in advance, and several kilometers to several hundred meters of branches to the variable charge application section. This is because the display on the display device 5 is required in the foreground.

  The storage unit 12 of the variable fee determination device 1 stores a prescribed fee for each route, an association table (FIG. 2), and variable fee management information (FIG. 3).

  The communication unit 13 of the variable fare determining device 1 communicates with the traffic information server to receive the traffic information and the traffic prediction of each route in each time zone, Send variable fee management information.

  The control unit 11 determines identification information (hereinafter, referred to as “display device information”) of the display device 5 to be displayed based on the association table between the display device 5 and the roadside communication device 6 that are installed correspondingly. . Further, the control unit 11 generates variable fee management information including information such as the variable fee and the display period.

  FIG. 2 is a diagram illustrating an example of an association table between a display device and a roadside communication device. As shown in FIG. 2, the correspondence table includes first display device information (for example, 1001) of the display device 5 installed correspondingly and first roadside communication device information (for example, 2001) of the roadside communication device 6.

  For example, as shown in FIG. 4, it is assumed that a point A, a point B (branch point), a point C (junction point), and a point D exist from upstream to downstream in the vehicle traveling direction. It is assumed that a plurality of routes (route X and route Y) exist between the point B and the point C. Furthermore, as a result of the traffic congestion prediction, the congestion degree of the route X is high during the time period from 10:00 to 12:59:59 on July 1, 2018, and the congestion degree of the route Y in the same time period is low. Suppose the case is predicted. In this case, even if the distance of the route Y is longer than the distance of the route X, the effect of reducing the congestion of the route X due to the detour of the route Y is expected because the fee of the route Y is low.

  In this case, the control unit 11 sets the applicable period of the variable fee to be from 10:00 to 12:59:59 on July 1, 2018, and sets the fee for each route to the prescribed fee (1000 And the route Y is determined to be a discounted fee (for example, 840 yen for three discounts of a prescribed fee of 1200 yen). Then, the display period of the variable fee is set to 9:59:00 to 12:58:59 slightly before the start time of the application period. The display object determines the first display device information (for example, 1001) of the display device 5 installed on the upstream side of the branch point (for example, 2 km upstream of the branch point).

  In addition, not only traffic jams based on traffic volume prediction but also variable rates can be set when traffic jams are predicted due to scheduled events (for example, construction). For example, if a construction schedule for the route X from 10:00 to 12:59:59 on July 1, 2018 is registered, the variable charge management information is generated by the operation of the attendant. You may. Based on the construction schedule information, the control unit 11 sets the variable charge application period from 10:00:12 to 12:59:59 on July 1, 2018, and sets a prescribed charge (discount) for the route X. None), and the route Y is determined to be a discounted fee. Then, 9:59:00 to 12:58:59 on July 1, 2018, slightly before the application start time, is determined as the display period of the variable fee. As a result, a detour effect of the construction section is expected, and congestion can be alleviated.

  Next, returning to FIG. 1, the display information creation device 2 will be described. The display information creation device 2 includes a control unit 21, a storage unit 22, and a communication unit 23.

  The communication unit 23 of the display information creation device 2 communicates with the communication unit 13 of the variable charge determination device 1 and receives the association table and the variable charge management information.
