About research
“Flow” in social systems (e.g. human mobility, car traffic, and goods distribution) displays complex behavior. For its vastness, it is difficult to simply apply its fundamental knowledge to real systems. To bridge the gap, we proposed a framework of mathematical modeling in which minimal subsystems (i.e. roads) were interconnected with each other. Through this method, we found that the networked flow displays “macroscopic jamming” that is distinctive from the normal jam observed in each subsystem. Moreover, we proved that this macroscopic jamming can be mitigated through a simple redistribution control on flow.
