Modeling and Simulating the Walking Behavior of Small Pedestrian Groups

In the virtual environment, the current methods can simulate some virtual human behaviors realistically. However, these methods take the crowd as a collection of separate individuals, which is difficult to generate interactive behaviors of the virtual crowd, especially for the small pedestrian groups with fewer members. Based on establishing the basic set of formations, this paper will model the walking behavior of small pedestrian groups, and control the interaction between group members. Regarding to the group with more members, we firstly separate the group into multiple smaller groups, and design an algorithm to maintain the consistency and adhesion between these detached groups. The simulation results show that the small pedestrian groups generated by our method can adjust their formations automatically according to the changing environment, and accomplish collision-free movement. Visually speaking, the behaviors of the small group we model are authentic.
