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.
