A method predicts whether an approaching passenger intends to travel on a passenger moving system having at least one movable pallet. The method includes positioning at least one monitoring device in the vicinity of the passenger moving system such that it monitors a detection area wherein the detection area includes at least a first detection area. The monitoring system then detects the presence of a passenger in the at least first detection area and monitors a trajectory of the passenger. A response is triggered at a control unit of the passenger moving system when the monitored trajectory of the passenger provides a predicted trajectory that reaches the entrance to the passenger moving system.
