Abstract: Human behavior may be predicted by building a model of people's physical movements along with a model that represents their affinities to various ontological elements, and their relationships to other people. The model may include a graph of interrelated people, as well as their hobbies, interests, employment, and other elements. The model may be analyzed by simulating people's activities as those activities interact with real or hypothetical networks. The real networks may be used to verify the model by comparing measured parameters to predictive parameters derived from simulation to calibrate the models. A calibrated model may then be used with a modified or hypothetical network to analyze the effects of changes to the real network.

Abstract: Methods, devices, and systems for automatically detecting, tracking, and validating transit journeys are provided. A transit data processing engine receives sensory data gathered by a plurality of sensors of a mobile device registered for automatic tracking of transit journeys and detects, based on transit data of one or more transit agencies and a first set of the sensory data, a potential transit event with the one or more transit agencies. Based on the transit data and a second set of the sensory data, received subsequently to the first set of the sensory data, the processing engine determines then whether the potential transit event defines a transit journey having a starting point with the one or more transit agencies. If the potential transit event defines the transit journey, the transit data processing engine continues to analyse the sensory data being received to detect an ending point of the transit journey.
