| Outline of Final Research Achievements |
A strong correlation was observed between the gait phase and the body response before and after the onset of vestibular electrical stimulation. The responses of the lower and upper limbs were understandable as a double inverted pendulum control system. However, the curvature obtained from the three roll angles of the head, chest, and hips was larger than that obtained from the actual walking trajectory, indicating that the camber angle, which is the body tilt, is not the only factor in curvature walking. The amplitude modulation of the fixed vertical motion at the starting point of the pedestrian observation did not reproduce the "slipping" as a result of objective observation of walking behavior. On the other hand, the avoidance distance to the obstacle increased, and the trajectory became bigrouped. This was interpreted as a result of a reduction in the reliability of the distance to the object to be avoided.

本成果は，人混みの混雑を緩和させることを目的とした群衆流動の制御のための歩行誘導技術に関するものである．人混みが発生する原因が向かい合う人通しの回避行動がうまくいかず，お互いが常に避け合い続けられるような流れが形成される前の段階が発生してしまうことが原因とされている．そこで本研究では歩行者の歩行誘導を効果的に実現するための歩行者の感覚刺激手法を提案することを目的としている．先行研究では，床に光学素子を敷設することで交通整理を実現することを狙っていたが，本成果はさらに実験室実験を実施することで単一の歩行者の歩行誘導効果を解析し，より誘導効果を高めるための指針を得た．
