ABSTRACT:
A device for measuring mean staying time of persons inside a building by processing signals from an entry/exit detector that outputs entry and exit signals when persons enter into and exit from the building. The device includes a staying measurer for determining the number of persons staying inside the building by subtracting the number of exit signals from the number of entry signals, an entry or exit measurer for determining the number of persons who have entered into or exited from the building by counting the entry or exit signals per predetermined period of time, and a calculating section for calculating the mean staying time of persons in the building during such a time period by dividing the number of persons staying inside at the time the unit time has expired by the number of persons who have exited.
