Abstract
To obtain an on-board device capable of estimating a speed of a preceding train.SOLUTION: An on-board device includes: a stop limit point receiving part 21 that receives a stop limit point from a ground device 30 that calculates the stop limit point indicating a point where a following train is allowed to travel on the basis of positional information about a preceding train; and a preceding train speed estimation part 22 that estimates a speed of the preceding train on the basis of an updated distance of the position indicated at the stop limit point and time required for update that is required for updating the position indicated at the stop limit point.SELECTED DRAWING: Figure 2
