Track occupied identification method based on switch curve information

Identification of occupied track is important to train navigation. With traditional train positioning method, it is difficult to identify track occupied in station with several parallel tracks. According to characteristic of switch curve, a track occupied identification method based on the switch curve information is proposed in this paper, in which inertial sensors and GNSS are employed to obtain train's operation state in switch, which will be used for the track occupancy identification. Experimental results demonstrate that the proposed method could realize track occupied identification to some extent with certain application value.
