1. A method for operating a railroad crossing, the method comprising, for rail vehicles approaching a railroad crossing:
using an axle counter to capture measurement data during a passage of the rail vehicle;
using arithmetic measures to calculate a velocity of the rail vehicle and an acceleration of the rail vehicle as properties of the rail vehicle from the measurement data of the axle counter;
specifying a time of closure for triggering a closure of the railroad crossing as a function of the calculated properties of the rail vehicle with reference to:
a calculated velocity as the rail vehicle is leaving the axle counter, and
a calculated acceleration as the rail vehicle is leaving the axle counter;
calculating a first further property as to whether the rail vehicle is a passenger train or a freight train, by arithmetic measures based on calculated axle spacings;
in a first checking step during the calculation of the first further property, checking whether identical or similar patterns can be identified in at least a predominant share of a sequence of axle spacings; and
if no pattern could be identified, assigning to the rail vehicle a property of a freight train as the first further property, or
if a pattern was identified, at least one of assigning to the rail vehicle a property of a passenger train as the first further property or performing a further checking step.
