Dynamics of group motions controlled by signal processing: A cellular-automaton model and its applications

Abstract Dynamics of collective motions in a multi-element system is studied by means of a two-dimensional cellular-automaton model. Two-state signals are introduced into the system in order to examine the effect of signal co-operation on the traffic-flowing phenomenon in cities. Critical density for phase transition varies as the color arrangement changes. A translation method of signal unit is proposed in examining the signal arrangement which yields the maximum flow rate of elements. Regular arrangements of different colors realize large flow rates in the system with crossings.
