Abstract
The objective of this paper is to find clues for improving inefficient traffic condition caused by deluded equilibrium (Nakayama. et. al, 1999). With this aim, a day-to-day dynamic traffic simulation model was developed. The simulation model comprises a traffic simulator and a simulator of driver behaviors. The latter simulates the driver's learning of route choice strategies. The results of simulation analysis indicate that providing traffic information and the reducing road capacity in roadways of which traffic volume is excessive, are efficient means for breaking drivers' negative beliefs and improving the inefficiency in deluded equilibrium.
