Forward monitoring device and forward monitoring method

Abstract

A forward monitoring device includes a map information storage unit that stores track information representing a location and a track geometry of a track, a train information acquisition unit that obtains train location information on a train, and an interceptor presence-absence determination unit that determines, based on the track information, the train location information, and interceptor candidate information, whether there is an interceptor between the train and a first monitoring scope, when the forward monitoring device monitors an obstacle on the track in the first monitoring scope, the interceptor being not the obstacle, the interceptor blocking a view of the first monitoring scope from the train, the interceptor candidate information indicating candidates for the interceptor that blocks a view from the train, the first monitoring scope including a spot on the track at a first distance from the train along the track in the travelling direction of the train.
