A method of determining information relating to the occupancy of a space that includes receiving first data relating to the occupancy of the space over a time period, receiving second data indicative of either times of decrementing events or times of incrementing events affecting the occupancy of the space during the time period, and either, for each decrementing event time, using the first data to obtain an estimated incrementing event time, or, for each incrementing event time, using the first data to obtain an estimated decrementing event time. The method has particular application in the determination of waiting times, for example in the context of queue monitoring.
