This paper proposes anticipation effect as another possible mechanism that might be origin of synchronized flow. The simulation of this effect is performed based on a new cellular automaton model. Since the overreaction in deceleration is removed due to the introduction of anticipation effect, qualitative changes of traffic flow characteristics appear compared with the results of NaSch model, and the congested traffic flow exhibits the features of synchronized flow. The authors also study the spatiotemporal patterns induced by an on-ramp. It is shown that the patterns are consistent with the three phase traffic theory. The work is expected to shed some light on the mechanism of synchronized flow.
