The present invention addresses the problem of providing an inexpensive signal system having a small number of devices while reliably preventing a collision with a preceding train and an obstacle. In order to solve the above problem, provided is a signal system characterized by having: a plurality of reflectors continuously disposed on a track; a train traveling on the track; a detection unit for detecting objects in front of the train; a specifying unit for specifying the reflectors from among the objects; and a control unit for setting a stop limit on the near side of the furthest one of the reflectors continuously seen from the vicinity of the train, providing a speed limit according to the stop limit, and braking the train when the traveling speed of the train exceeds the speed limit. |
