| 研究実績の概要 |
Analyses of the impact of social relations and social interactions on pedestrian motion patterns have been pursued. In particular, the dynamics of collision avoidance between pedestrian two-person groups and individual pedestrians in an ecological environment have been studied. Our findings revealed that, as social bonding and interaction intensity increase, collision avoidance becomes more pronounced. Additionally, we observed that the likelihood of intrusion decreases as the strength of social bonding and interaction intensity increases.
Furthermore, to understand how visual stimuli could be used to influence pedestrian motion (steering, etc.), a preliminary study to evaluate differences in tracking performances when viewing natural motion against artificial motion has been designed.

理由
The carried out studies aligned with the planned research and provided insights into the influence of social bonding within groups on the movement of individuals in crowds. This represents a significant advancement in the comprehension of how macro-level social behaviors can impact the dynamics of pedestrians. The potential application of these findings to develop more authentic crowd models and simulations is being evaluated.
Furthermore, initial investigations have been conducted on the impact of visual cues in regulating or directing crowd velocity. Notably, particular attention has been paid to selecting the appropriate type of stimuli, as previous literature has shown insufficient attention to this subject matter.

| 今後の研究の推進方策 |
To study how visual stimuli can be used to steer pedestrian individuals, a better understanding of human gaze mechanics is necessary. The mechanism of smooth pursuit will be examined. A study designed to evaluate differences in tracking performances when viewing natural motion against artificial motion will be conducted. Some preliminary studies are also necessary to validate the use of some of the experiment material (stimuli target, etc.). Based on the results of these studies, the use of visual stimuli to affect pedestrian motions will be evaluated. The type of stimuli to select for this purpose will be guided by these results (more natural, easier to track, and less intrusive).
The use of reinforcement learning algorithms for crowd modeling/steering algorithms will also be investigated.
