Abstract
A people flow estimation system uses input of movement model data to create movement demand data and estimate the flow of people inside a building using architectural model data. The people flow estimation system is characterized by identifying the names or uses of rooms in the building and the density of in-building personnel; recording occurrence distribution of movement demand inside the building with respect to a reference time; converting the architectural model data into layout data; calculating the number of in-building personnel in a room; and calculating movement demand data from the number of in-building personnel and the data from the recorded movement demand distribution.
