According to the present invention, this object is attained by a device for danger zone monitoring at a grade crossing having at least one radar sensor for monitoring the danger zone, and having an identification unit which is designed to
ascertain object trajectories from sequences over time of object positions of respective objects detected by radar sensors, moving through the danger zone,
detect the position of at least one traffic path with the aid of an accumulation of object trajectories,
ascertain the positions of barrier straight lines with the aid of radar reflections of the closed barriers, and
determine the danger zone to be monitored by linking information on the detected position of the at least one traffic path with information on the ascertained position of the barrier straight lines.
