A ground control device includes a control unit that determines a control mode of operation control on a train in a communication area of a radio communication apparatus, based on information on a communication level indicating a communication state between the train and the radio communication apparatus determined in a predetermined period, and performs train operation control according to the determined control mode on a train entering or approaching the communication area after the control mode is determined, and a storage unit that stores one or more pieces of the information on the communication level on one or more of the radio communication apparatuses.

To improve throughput rates of packets transmitting positive train control (PTC) messages in an asynchronous wireless network that supports controlling movement of trains, data rates are adjusted based one or more conditions of the link. Modulation and coding schemes with less overhead can be employed to increase the data rate at which information is transferred when an estimated link quality or conditions are relatively good. Conversely, when the estimated link quality is relatively poor, more robust modulation and coding schemes for transmissions can be used to maintain link performance but at the cost of reduced data rates. Optionally, if the estimated link quality is higher than required to achieve a predefined maximum transmit rate at a given default power rate, transmit power can be reduced to that necessary for transmit at the predefined maximum transmit rate.

A communication status inference apparatus acquires a wireless signal as data indicating a radio wave environment of a wireless base station installed along a railway line when an onboard system and the wireless base station perform cognitive wireless communication, the wireless signal being received by a monitoring reception apparatus in the vicinity of the wireless base station, and executes an inference process of inputting the acquired data indicating the radio wave environment to a communication status inference model and outputting frequency-specific communication status information based on a signal-to-noise ratio (SNR) at which the wireless base station performed wireless communication under the radio wave environment. The communication status inference model is a machine learning model that has undergone learning using training data with the data indicating the radio wave environment as an input and with the frequency-specific communication status information based on the SNR as an output.

In a method for mixed operation of a section of railroad line, the section of line is trafficable by trains equipped with a train control system, and by trains not equipped with this train control system. The section of line is provided with a switch so that in the event that a train not equipped with the train control system is to enter the section of line from the direction of a side track, the section of line is indicated as occupied. The occupied indication is triggered by a first throwing of the switch in the direction of the side track. After the train not equipped with the train control system has passed through, the occupied indication is canceled. The cancelation is triggered by a second throwing of the switch. After throwing of the switch, a clearing run is carried out on the section of line by an equipped train.
