Each display device 5 is installed at a position where the driver of the vehicle can see it while driving the vehicle. Each roadside communication device 6 is installed at a position corresponding to the display device 5 .

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

The control unit 11 of the variable fare determination device 1 predicts the degree of congestion and the required time from the congestion information and congestion prediction of each route in each time period. Then, based on the degree of congestion and required time for each route in each time period, the toll for each route in each time period (hereinafter referred to as "variable toll") will be calculated in consideration of the effect of alleviating congestion caused by changing the toll. ) is determined. Here, the "variable charge" 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 period earlier than the applicable period of the variable charge by a predetermined time as the display period for the variable charge, and selects the display device 5 to be displayed among the plurality of display devices 5. decide.

Here, the reason why the display period of the variable toll is set to a time zone earlier than the applicable period by a predetermined time is that the driver can select the route in advance, and the branch to the section to which the variable toll applies is several kilometers to several hundred meters. This is because it is necessary to display on the display device 5 in front.

The storage unit 12 of the variable fare determination device 1 stores the stipulated fare for each route, the correspondence table (FIG. 2), and the variable fare management information (FIG. 3).

The communication unit 13 of the variable fare determination device 1 communicates with the congestion information server to receive traffic congestion information and traffic congestion prediction for each route in each time zone, and communicates with the display information creation device 2 to create a correspondence table and Transmit variable charge management information.

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

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

For example, as shown in FIG. 4, point A, point B (branching point), point C (merging point), and point D are present from upstream to downstream in the traveling direction of the vehicle. A case is assumed in which a plurality of routes (route X and route Y) exist between the B point and the C point.
Furthermore, as a result of traffic congestion prediction, during the period from 10:00:00 to 12:59:59 on July 1, 2018, route X will be highly congested, and route Y will be less congested during the same time period. Assume a case where it is predicted that In this case, even if the distance of the route Y is longer than the distance of the route X, since the toll of the route Y is low, the detour of the route Y is expected to alleviate the congestion of the route X.

In this case, the control unit 11 sets the application period of the variable charge to 10:00:00 to 12:59:59 on July 1, 2018, and sets the charge for each route to the prescribed charge (1000 for route X). Yen), and route Y is determined to be a discounted fare (for example, 840 yen, which is 30% off the standard charge of 1200 yen).
Then, the display period of the variable charge is set to 9:59:00 to 12:58:59, which is slightly before the start time of the applicable period. For the display target, the first display device information (for example, 1001) of the display device 5 installed upstream from the branch point (for example, 2 km upstream from the branch point) is determined.

In addition, variable tolls can be set when congestion is predicted not only due to traffic volume prediction, but also due to scheduled events (for example, construction work, etc.).
For example, if a construction schedule is registered for Route X from 10:00:00 to 12:59:59 on July 1, 2018, variable charge management information will be generated by the operation of the staff. may Based on the construction schedule information, the control unit 11 sets 10:00:00 to 12:59:59 on July 1, 2018 as the application period of the variable charge, and sets the prescribed charge (discount None), and route Y is determined to be a discounted fare.
Then, as the display period of the variable charge, the period from 9:59:00 to 12:58:59 on July 1, 2018, which is slightly before the application start time, is determined. This is expected to have the effect of detouring the construction section, and traffic congestion can be alleviated.

Next, referring back to FIG. 1, the display information creating device 2 will be described. The display information creation device 2 includes a control section 21 , a storage section 22 and a communication section 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 to receive the correspondence table and the variable charge management information. The storage unit 22 of the display information creation device 2 stores a correspondence table and variable charge management information.

FIG. 4 is a diagram showing a display example of variable charge information on a display device.

As shown in FIG. 4, the display device 5 displays an image of the entire route, the required time for each route, variable tolls, and the like. For example, point A, point B (branching point), point C (merging point), and point D are displayed from upstream to downstream in the traveling direction of the vehicle. In addition, multiple routes (route X and route Y) between points B and C are displayed, and information on the required time for each route (route X and route Y) and variable fare (price and type (rule/discount)) is displayed.

Here, variable charges may be set for each vehicle type. In this case, if variable tolls for all vehicle types are displayed, the amount of display information will be too large, and visibility for the driver of the vehicle will be degraded. In this case, variable tolls for each vehicle type may be alternately displayed.

Furthermore, in FIG. 4, both the ownership time and the variable fee are displayed, but if the size of the display board cannot be increased, the visibility from the driver of the vehicle deteriorates due to the excessive amount of displayed information. . In this case, the required time and the variable charge may be displayed alternately.

Specifically, as shown in FIG. 13, the distance 10.00 km of the antenna 63 in the second roadside communication device information (2011) and the distance 7.00 km of the display device 5 in the second display device information (1011) is 3.00 km. Therefore, 90 seconds (correction time) calculated by adding the average running speed of this section to the communication date and time of the antenna 63 of the second roadside communication device information is set.
Then, by comparing the time obtained by adding the correction time to the recorded time of the traffic record and the information displayed on the display device 5 of the second display device information, it is determined whether or not the recognition is possible. The correction time is determined according to the difference distance. The longer the differential distance, the longer the correction time, and the shorter the differential distance, the shorter the correction time.

Similarly, the differential distance between the distance of 9.40 km to the antenna 63 in the third roadside communication device information (eg, 2012) and the distance of 10.00 km to the display device 5 in the second display device information (eg, 1011) is 0.60 km. be.
