Train-running management device

A train-running management device that comprises a ground running control unit to transmit a running pattern, or information contributing to generation of the running pattern, to a control-target train, wherein

• in a case where a first running pattern when the control-target train runs without being affected by a preceding train and a subsequent train is divided into an acceleration section where a train accelerates, and deceleration section where a train decelerates, and an intermediate section between the acceleration section and the deceleration section and in a case where a speed in the intermediate section is a first speed, when the ground running control unit determines that the control-target train affects a subsequent train, the ground running control unit changes the first running pattern to be indicated to the control-target train to execute running control such that a speed of the control-target train in the acceleration section becomes higher than the first speed and a speed of the control-target train in the intermediate section becomes lower than the first speed.
