Abstract: Controlling a level crossing includes one or more transceivers located in proximity of a level crossing area on a first side of a railway track; corresponding passive reflective targets located in proximity of the level crossing area on a second side of the railway track opposite to the first side where each transceiver is located and a control unit connected to each transceiver. Each target is arranged to receive RF signals coming from each transceiver and to send back corresponding reflected signals. Each transceiver is arranged to elaborate said reflected signals to calculate predetermined parameters values. Also, the control unit is arranged to acquire said parameters values from each transceiver and to elaborate them to detect the presence of a train in an area around the level crossing area and, in case of presence of said train, to send a warning message and/or close bars of the level crossing.

Abstract: Controlling a level crossing of a railway track by providing a train having an onboard processor communicating with a wayside processor associated to a level crossing, said train having a forward end and a rear end; moving the train forward along the railway track lowering down gates of the level crossing when train is at a predetermined distance upon detection of the train approaching the level crossing; when the forward end passes over a first reference point defining the beginning of an island area of the level crossing, sending a first message from the onboard safety processor towards the wayside processor informing that the train is approaching the level crossing; maintaining down gates; when the rear end passes over a second reference point defining the end of the island area, sending a second message from the onboard safety processor to the wayside processor informing that the train has left the level crossing; and lifting the gates.

Abstract: A system for controlling a level crossing between a railway track and a road, the system comprising a first couple of transmitters and a second couple of transmitters in proximity of a level crossing area; a first couple of receivers and a second couple of receivers opposite to the transmitters with respect to the railway track, the first couple of transmitters and receivers located on a first side of the road and the second couple of transmitters and receivers located opposite to the first side, a control unit sending and receiving signals from said transmitters and receivers, wherein each couple of transmitters transmits a first beam from a first transmitter towards a corresponding first receiver, and a second beam from a second transmitter towards an opposite second receiver, the control unit activates sending at least one second beam and sends a warning message and/or close bars of the level crossing upon interruption of at least one first beam due to the presence of the train on the railway track.
