Abstract
To use the concept of dynamic group to study crowd following behaviors, group related rules considering pedestrians’ movement characteristics under relevant configurations are proposed. A hierarchy of individual and subordinate leader–follower groups is devised. The hierarchy is allowed to alter in the run-time so that groups can be dynamically added or removed. Through this method, crowd following behaviors can be modeled with the concept of group in simulations. Data structures and algorithms are designed in order to implement the proposed method into a GPU-based heterogeneous computing platform. Numerical experiments demonstrate the model’s capability to capture phenomena such as self-organization of pedestrian lanes. By calibrating density-dependent parameters, the simulated speed-density relationship shows consistency with the Weidmann fundamental diagram under conditions dominated by dynamic following behaviors. Since such dynamic behaviors are key factors in crowd flows, this work suggests that dynamic group modeling can provide new insights for transportation researchers studying collective dynamics.
