Abstract

Even when there is no accurate position information of a traffic light provided on a traveling line, a state of the traffic light is identified with high accuracy. Therefore, one of representative state determination devices is a state determination device including a traffic light database configured to store, based on an image in a traveling direction of a traveling train, information related to a traffic light included in the image, a sensor unit attached to the train, and a traffic light specification unit configured to specify the traffic light from an image acquired by the sensor unit. The traffic light database includes movement trajectory information of a traffic light calculated from an image of the traffic light included in the image in the traveling direction and/or appearance region information of the traffic light calculated from distance information from a line on which the train travels to the traffic light, and the traffic light specification unit specifies the traffic light from the image acquired by the sensor unit with reference to the traffic light database and determines a state of the corresponding traffic light.
