[0043] According to at least one embodiment, the apparatus or program requests the other vehicle not to enter the traffic path based on the first information and the second information. As an example, the request is to transmit to a machine or device by some electromagnetic signal that the other vehicle shall not enter the traffic path, or that the other vehicle should not enter the traffic path. Or, as an example, the request is that the vehicle's machine receives status information and the vehicle's device transmits a signal to the vehicle's power to block the power to enter the traffic path. Or, the request is that the vehicle's machine receives status information and notifies the vehicle's driver that the vehicle should not enter the traffic path. As an example, to notify this, the vehicle's machine or device is programmed or made to play a predetermined sound (for example, the voice "Please do not enter this traffic path"), sound a predetermined alarm, emit a predetermined light, or emit a predetermined vibration. Or, the request is that the control machine or the device of the control system receives status information and notifies the controller using the control machine or the control system that the vehicle should not enter the traffic path. The notification method can be realized by one or more of the above methods. Or, the control machine or the control system transmits a signal to block the power to enter the traffic path to the vehicle's device or the vehicle's power. As an example, the apparatus receives, as the first information, information that an airplane on runway C has been given permission to land, receives, as the second information, information that another airplane has entered runway C, and requests that the airplane related to the second information (that "other airplane") not enter runway C. An example of the request is that the device of the airplane related to the second information transmits a signal to block the power to enter the traffic path to the vehicle's power. Or, the device of the airplane related to the second information notifies the driver of that airplane that the airplane should not enter the traffic path. Or, the device of the control machine or the control system receives status information and notifies the controller using the control machine or the control system that the vehicle should not enter the traffic path. The above examples are to request that the airplane related to the second information does not enter.On the other hand, as another embodiment, it is also possible to require that an airplane related to the first information does not intrude. This method can be implemented by any one or more of the above methods.

[0044] According to at least one embodiment, one or more devices can be replaced with AI. As an example, the AI transmits and receives the first or second information. Or, the AI is requested to ensure that the vehicle does not intrude into the traffic route. Or, the AI requests another vehicle not to intrude into the traffic route.
