Fraunhofer IAIS develops many data mining algorithms that answer both questions for different scenarios. In this work, we present a method that uses no frequency counts but points of interesting locations (POI) and the total number of pedestrians. We utilise model trees to compute frequency estimates and show and evaluate this approach on a public building scenario taken from an industrial project.entraffic information systemtraffic flow estimation005006629presentation
