In this paper, we introduce a driver behavior model that can show realistic behaviors of vehicle. We have developed the system which links macroscopic traffic simulator (TS) with driving simulator (DS). This system can evaluate various ITS services by observing and analyzing both the behavior of DS driver and the effect on the traffic situation. In this system, the behavior of vehicles controlled by this system is required to be similar to that of real vehicles. We construct the driver behavior model which contains sub-modules for perception of information about nearby vehicles, judgment and action selection, the modules are applied for various situations. Using this driver behavior model and a vehicle dynamics model, we can simulate realistic vehicle behavior decided by interactions with neighboring vehicles.
