Determine (S101) (calculation means). A method for determining the degree of urgency will be described later.

  In addition, the traffic control server 3 stops the ETC process between the ETC antenna 7 and the ETC vehicle by giving an instruction to stop the ETC process to the lane control device 12 (S102).

  Subsequently, it is determined whether the toll gate (first toll gate) is a main toll gate installed on the main line of the toll road based on the toll gate type of each toll gate stored in the database 170 (S103). (First determination means).

  As a result of the determination in S103, when it is determined that the toll booth (first toll booth) is the main toll booth (Yes in S103), the toll booth (first toll booth) using the urgency level of each toll booth Is determined to be higher than the urgency level of the next toll gate (second toll gate) (S104) (comparison judgment means).

  As a result of the comparison determination, when it is determined that the urgency level of the toll gate (first toll gate) is equal to or higher than the urgency level of the next toll gate (second toll gate) (Yes in S104), the traffic control server 3 starts. An instruction to open the gate of the control device 9 and an instruction to display a passage permission instruction on the display unit 304 of the roadside display device 8 are transmitted to the lane control device 12 (S105) (first traffic control instruction means).

  If it is determined that the urgency level of the toll gate (first toll gate) is less than the urgency level of the next toll gate (second toll gate) (No in S104), the traffic control server 3 An instruction to control the closing of the gate and an instruction to display a passage prohibition instruction on the display unit 304 of the roadside display device 8 are transmitted to the lane control device 12 (S106) (first traffic control instruction means).

  On the other hand, as a result of the determination in S103, if it is determined that the toll gate (first toll gate) is not the main toll gate (No in S103), then whether the toll gate (first toll gate) is the entrance toll gate or not Is determined (S107).

  As a result of the determination in S107, when it is determined that the toll gate (first toll gate) is the entrance toll gate (entrance of S107), the traffic control server 3 instructs the start control device 9 to close the gate and the roadside An instruction to display a traffic prohibition instruction on the display unit 304 of the display device 8 is transmitted to the lane control device 12 (S108) (second traffic control instruction means). When it is determined that the toll gate (first toll gate) is the exit toll gate (exit of S107), the traffic control server 3 instructs the road control device 8 to open and control the gate of the transmission control device 9. An instruction to display the passage permission instruction on the display unit 304 is transmitted to the lane control device 12 (S109) (third traffic control instruction means).

  Next, traffic control by the roadside device 10 performed based on each traffic control instruction of the traffic control server 3 will be described.

The roadside display device 8 displays a passage permission instruction on the display unit 304.

  Further, based on an instruction to the lane control device 12 of the traffic control server 3 in S106, the transmission control device 9 installed in each lane of the toll gate (first toll gate) (main toll gate) performs gate closing control. At the same time, the roadside display device 8 displays a traffic prohibition instruction on the display unit 304 (first traffic control means).

  Based on the instruction to the lane control device 12 of the traffic control server 3 in S108, the transmission control device 9 installed in each lane of the toll gate (first toll gate) (entrance toll gate) performs gate closing control. The roadside display device 8 displays a traffic prohibition instruction on the display unit 304 (second traffic control means).

  Further, based on an instruction to the lane control device 12 of the traffic control server 3 in S109, the transmission control device 9 installed in each lane of the toll gate (first toll gate) (exit toll gate) performs gate opening control. At the same time, the roadside display device 8 displays a passage permission instruction on the display unit 304 (third traffic control means).

  FIG. 13 is a conceptual diagram showing an example of a data configuration in which the degree of urgency is displayed together with information on an earthquake occurrence area, a toll booth, and an earthquake intensity.

  Seismic intensity 5 in region A, seismic intensity 6 in region B, seismic intensity 5 in region C, seismic intensity 5 in area C, urgency 2 for toll booth associated with area A, urgency 3 for toll booth associated with area B, The urgency level of the C toll booth associated with region C is 1. Here, the urgency is determined as follows, for example. The urgency level is set to 1, 2, 3 in three steps in descending order of urgency level. The urgency is determined according to the seismic intensity. The urgency is 3 when the seismic intensity is 7 or 6 or higher, the urgency is 2 when the seismic intensity is 6 or 5 or lower, and the urgency is 5 when the seismic intensity is 5 or lower. Set to 1. For the sake of simplicity, the urgency level is determined only by the seismic intensity. However, it may be determined by the strength of the rock in the area where the toll gate is installed, weather conditions, weather, deterioration of nearby roads, completion date, etc. .

  By performing the above traffic control, the traffic control system 100 calculates the degree of urgency based on the earthquake occurrence information received from the seismometer server 4 when an earthquake of a certain magnitude or larger occurs, and when the toll gate is the main toll gate Compares the urgency of the toll booth (first toll booth) and the next toll booth (second toll booth), and the urgency at the first toll booth is higher than the urgency at the second toll booth In this case, the traffic control is performed to guide the passing vehicle toward the second toll gate. If the urgency level at the first toll gate is lower than the urgency level at the second toll gate, the first toll gate The control to keep the passing vehicle at is performed.

  Also, if the toll gate is an entrance toll gate, traffic control is performed so that the toll vehicle does not enter the toll road. If the toll gate is the exit toll gate, the toll vehicle is guided from the toll road to the general road. Do traffic control.

  When the traffic control system performs the above traffic control, more appropriate traffic control can be performed on the passing vehicle.

  Moreover, although the above-mentioned embodiment is expressed as a traffic control system such as a toll road, the present invention is generally applied to a control system that calculates an urgency level based on predetermined data and guides evacuation based on the urgency level. It can be done.
