Building occupancy estimation with people flow modeling in AnyLogic

With more and more high rise buildings in modern cities, people flow and occupancy estimation has gained lots of attention in recent years. Most previous works on this topic are based on the Kalman filter (KF) due to its high efficiency. However, the Kalman filter requires good people flow models which are usually hard to get due to the complexity of people behavior. People simulation softwares such as AnyLogic have the capability to simulate complicated people behaviors in buildings. In this work, AnyLogic is adopted to simulate people flow and identify the people flow model, which is further used in the Kalman filter to estimate people flow in both simulation and real people experiment.
