TRAVEL PATTERN CREATION DEVICE, TRAVEL PATTERN CREATION METHOD AND AUTOMATIC TRAIN OPERATION DEVICE

In the method that a collision risk is estimated to reduce a collision risk in a section where a train is traveling, and if the estimated collision risk is greater than a predetermined reference value, and the travel pattern of the travel section is repeatedly corrected until the collision risk becomes below the reference value, there is a problem that an inter-station travel time increases with the correction of the travel pattern, and a travel time between stations specified on a schedule cannot be satisfied. In a track transportation system that travels on a track, a travel pattern is created from a risk value for each section obtained by dividing stations into a plurality of sections and the travel time between stations.
