A method for continuously monitoring the occupancy of a passenger transport vehicle, in particular a railway carriage, the passenger transport vehicle comprising - at least one access for entering into an interior of the passenger transport vehicle and/or for exiting from the interior, - a plurality of separate lounge areas located in the interior, - a corridor which connects the access to the lounge areas, in such a way that a person can step directly into each of the lounge areas from the corridor, and - a sensor device arranged on or in a floor of the corridor, which comprises a plurality of pressure measuring points distributed over the area of the corridor, at which pressure data relating to pressure forces orientated at least perpendicular to the floor can be collected, wherein positions of the pressure measuring points relative to the access and the lounge areas are known, wherein the pressure data are transmitted to a data processing device, by means of which the pressure data are evaluated using an evaluation algorithm, wherein by means of the evaluation algorithm i) pressure data resulting from a plurality of pressure measuring points adjacent to one another, which result due to at least one foot of a person standing up in the corridor, are recognised as a human footprint; ii) the pressure data are analysed historically and recognised footprints are registered as belonging together and the person who is present in the corridor is thereby recognised; iii) the recognised person is assigned to one of the lounge areas as soon as he or she leaves the corridor, wherein the assignment is made depending on at least one position and/or direction of movement of the person in the corridor that the person had immediately before leaving the corridor; iv) when a person enters the corridor, this person is assigned as coming from one of the lounge areas, wherein the assignment is made depending on at least one position and/or direction of movement of the person in the corridor that the person had immediately upon entering the corridor; wherein a number of people with which the at least one lounge area is occupied is recorded and continuously updated, so that a statement can be made as to how many people are currently in the lounge area. - at least one access for entering into an interior of the passenger transport vehicle and/or for exiting from the interior, - a plurality of separate lounge areas located in the interior, - a corridor which connects the access to the lounge areas, in such a way that a person can step directly into each of the lounge areas from the corridor, and - a sensor device arranged on or in a floor of the corridor, which comprises a plurality of pressure measuring points distributed over the area of the corridor, at which pressure data relating to pressure forces orientated at least perpendicular to the floor can be collected, wherein positions of the pressure measuring points relative to the access and the lounge areas are known, wherein the pressure data are transmitted to a data processing device, by means of which the pressure data are evaluated using an evaluation algorithm, wherein by means of the evaluation algorithm i) pressure data resulting from a plurality of pressure measuring points adjacent to one another, which result due to at least one foot of a person standing up in the corridor, are recognised as a human footprint;
