A Mobility Simulation Framework Of Humans With Group Behavior Modeling

We present a mobility simulation framework that simulates the movement behaviors of people to generate spatiotemporal movement data. There is a growing interest in applications that make use of patterns mined from spatio-temporal data. However, since the availability of actual spatio-temporal movement data in the public domain is limited, it is useful to have simulation frameworks that generate data close to the real life behavior of people, so that data mining techniques can be tested. We argue that modeling group behavior effectively is a key element of any real-life simulation framework, because there are many applications that require the knowledge of groups and events. In this work, we propose generic models to represent individual and group movement behaviors. We present an algorithm that takes various behaviors created using the proposed models, and generates spatio-temporal movement data for as many individuals as needed. Experimental analysis shows the efficacy of the proposed framework handling a broad spectrum of behaviors with high scalability.
