Abstract

The generation of synthetic human mobility scenarios is often realized through data-driven or rule-based approaches. They work in a fire-and-forget principle and provide limited support to induce controlled activities in simulated scenarios. However, including controlled preset activities in the generation phase enables the creation of mobility scenarios that include a-priori known outliers or key events. Such mobility test datasets might be used in outlier detection for machine learning algorithms or for inducing non-typical mobility, where models do not exist or are too complex to construct. In this work we propose an activity-based scheduler to include controlled preset key events in the scheduling process of daily human mobility scenarios. Further, with our rule-based approach we can synthesize new activities of a target region even when initial data is unavailable or missing. In addition we propose a hierarchical methodology to iteratively add activities according to their number of constraints and provide a publicly available Python-based implementation. Our validation shows that our approach is able to integrate non-typical behavior in typical mobility scenarios.
