Abstract
In this study, a wayfinding experiment in a maze was undertaken, where each pedestrian drew the imaginary path which he was trying to take at the starting point and at each point where his path image changed. Since path images corresponded to the actual paths which were taken by pedestrians, pedestrians can be regarded as walking on the basis of their path images in their mind. According to the tendencies of change of path images, the simulation model for wayfinding behavior was updated, and availability of the model was acknowledged by the inspection of the simulation examples.
