A method for detecting an anomaly in a passenger flow towards a transport device is disclosed. The method comprising the steps of aggregating historical data relating to said passenger flow and determining a forecast passenger flow value for a target time frame on the basis of said historical data. The method includes computing a first forecast on the basis of the passenger flow in a first set of said time frames directly preceding said target time frame. The method also includes computing a second forecast on the basis of the passenger flow in a second set of said time frames, said second set of time frames having occurred on a same weekday and at a same time as the target time frame, in weeks preceding the target time frame. The method further comprises combining the first and second forecasts.
