Vadere-A Simulation Framework to Compare Locomotion Models

摘要

Unlike many dynamical systems in physics, there is no universally accepted locomotion model for crowd dynamics. On the contrary, many different approaches compete, of which some are more suitable for a specific scenario, like evacuations, than others. We showcase how to compare microscopic models based on a real-world experiment using the open-source simulation framework Vadere and two models: the Optimal Steps Model and the Behavioral Heuristics Model. Aside from quantitative aspects, we discuss visual results. Both models are able to reproduce the density-speed relation to a reasonable degree. We also identify model characteristics that led to deviations, thus enhancing our understanding of both models and facilitating the decision which model to choose to investigate a particular real-world situation.
