Timing of traffic lights and phase separation in two-dimensional traffic flow Original Research Article

In this paper, we study the effects of traffic light period in two-dimensional Biham–Middleton–Levine (BML) traffic flow model. It is found that a phase separation phenomenon, in which the system separates into coexistence of free flow and jam, could be observed in intermediate vehicle density range when traffic light period image. We have explained the reason of occurrence of phase separation and investigated its behavior in different traffic light period.
