This paper investigated the effect of driving assistant system which is designed for anticipating pre-preceding vehicle on traffic flow stability. The authors have proposed a driving assistant system which is referred to as PRE3 (prediction by pre-preceding vehicle) and confirmed through a driving simulator (DS) experiment that it is efficient for the following driver to anticipate the pre-preceding vehicle in order to make the platoon stable. In this paper, it is investigated whether the effect of PRE3 is extended to the macroscopic stability of traffic flow. Driver's behavior is modeled based on an Optimal Velocity (OV) model and validated using a DS experiment data. Numerical analysis through a traffic simulator confirmed that PRE3 is also efficient to make the traffic flow stable without any deterioration of velocity along a freeway corridor.
