Abstract: An occupancy estimator calculates an occupancy estimate (x ) of a region based on sensor data (z) provided by one or more sensor devices and a model-based occupancy estimate generated by an occupant traffic model (f). The occupant traffic model (f) is based on predicted movement of occupants throughout a region. The occupancy estimation system includes an occupancy estimator algorithm (20) that combines the sensor data (z) and the model-based occupancy estimate generated by the occupant traffic model (f) to generate an occupancy estimate (x) for the region.

Abstract: A system generates occupancy estimates based on a Kinetic-Motion (KM)-based model that predicts the movements of occupants through a region divided into a plurality of segments. The system includes a controller for executing an algorithm representing the KM-based model. The KM-based model includes state equations that define each of the plurality of segments as containing congested portions and uncongested portions. The state equations define the movement of occupants based, in part, on the distinctions made between congested and uncongested portions of each segment.

Abstract: A model-based egress support system (10) employs models to generate an optimal egress route for occupants in a region. The system includes an egress controller (16) that is connected to receive detection data. The egress controller (16) executes an optimization algorithm (22) to select an egress route based on model-based egress estimates generated by an egress prediction model (18) in response to the detection data.
