| Research Abstract |
The mechanism of emergence of macroscopic states in flow-dynamics of many body systems such as a traffic flow and self-driven particles is investigated, and is understood as a dynamical phase transition as well as a Hopf bifurcation phenomenon. We performed an experimental study for forming a traffic jam using real vehicles in the arena of Nagoya-Dome, and obtain precise sequential data of the process of forming a jam cluster. Moreover, computer simulations of mathematical models for pedestrians, crowd people, and collective bio-motions are done, and the real phenomena, especially, group-intelligent behaviors are well recreated
