As shown in FIG. 7A, the rear wheel 18 includes a drive wheel 18 a that is connected to the drive shaft 21 and applies a driving force on the road 2 and the rail 3, and an outer wheel 18 b that contacts only the road 2. As shown in FIG. 7B, the front wheel 17 is disposed outside the front guide wheel 19 so as not to contact the rail 3.

  The vehicle 1 travels on the road 2 by wheels 17 and 18 of rubber tires in the same manner as a general bus, and drives on the rail 3 while being guided along the rail 3 by the front guide wheel 19 and the rear guide wheel 20. Travel by wheel 18a. Further, in the conversion from the road 2 to the rail 3, the front and rear guide wheels 19 and 20 are lowered by hydraulic pressure in the mode conversion area 12 and engaged with the rail 3, and the front wheel 17 is pulled up to be in the rail running state. In the conversion from the rail 3 to the road 2, the front wheel 18 is lowered and the front and rear guide wheels 19 and 20 are pulled up to be in a road running state.

In this dual mode transport system, if a general vehicle traveling on the road accidentally enters the rail, the vehicle 1 will be obstructed and become extremely dangerous, and traffic safety will not be maintained. End up.

Both are marked R on the rail 3 side. In this state, when the vehicle 1 traveling on the road 2 approaches the gate 7, the display unit 14 of the reception display device 8 stops outward by the R signal shown (steps S1 and S2). The stopped vehicle 1 transmits an approach request signal and a gate opening signal to the reception display device 8 by the remote signal transmitter 6 (step S3). When receiving the entry request signal and the gate opening signal transmitted from the vehicle 1, the remote signal receiver 13 of the reception display device 8 sends the received entry request signal and the gate opening signal to the road side opening / closing control unit 16a. When the approach request signal is sent, the road side opening / closing controller 16a operates the approach request detection relay DmR and enters the vehicle entry permission process (step S4). When entering the vehicle entry permission process, if the vehicle approach signal is not sent from the receiver 9a and the vehicle approach detection relay AR is not operating, the vehicle entry permission process is not advanced, and the R indication on the display unit 14 is displayed. Is not permitted to enter the vehicle (step S5). If the R indication on the display unit 14 does not switch to the Y indication even if the vehicle 1 transmits the entry request signal and the gate opening signal to the reception display device 8, the vehicle 1 changes the stop position and changes the entry request signal and the gate opening.

When the central control device 10 inputs and confirms the vehicle entry detection signal , the confirmation detection relay AcR is operated to operate the vehicle entry permission relay OKR, and the R display on the display unit 14 is switched to the Y display. The entry is permitted (steps S5 and S7). When the vehicle entry permission relay OKR is operated, the gate opening relay GOR is operated to send a gate opening signal to the gate driving unit 7a to open the gate 7 (step S8). When the gate 7 is opened and a signal indicating that the gate 7 is fully opened is sent from the gate drive unit 7a, the gate full open confirmation relay AOR is operated to switch the Y display on the display unit 14 to the G display (steps S11, S12). ). After confirming the G display on the display unit 14, the vehicle 1 travels and enters the gate 7 (step S11). When the vehicle approach signal sent from the receiver 9a is cut off and the vehicle approach detection relay AR is restored, the vehicle approach detection relay ENR and the vehicle entry permission relay OKR are restored and the display unit 14 Switch G display to R display. When the vehicle 1 entering the gate 7 travels and detects the vehicle 1 with the gate control ground element W02 provided on the rail 3 side (step S12), the gate opening relay GOR is restored and sent to the gate drive unit 7a. The gate open signal is cut off and the gate 7 is closed (step S13).

  Similarly, when the vehicle 1 traveling on the rail 3 enters the road 2, the gate 7 is opened and closed to prevent a general vehicle from entering the rail 3.
