1. A method for controlling a level crossing having barriers and signals, the method comprising:
establishing a duration of a level crossing closure based at least in part on first signals caused by a first ultrasonic wave conducted in a first rail running over the level crossing and second signals caused by an ultrasonic wave conducted in a second rail running over the level crossing;
detecting the first signals and the second signals in a first time period, in which the level crossing is closed and the rails are clear; and
detecting the first signals and the second signals in a second time period, in which the level crossing is open;
wherein establishing the duration includes a first comparison of the signals detected in the first time period to the signals detected in the second time period.
