This study tries to find the influence factors of pedestrian way finding in pedestrian malls. The structural equation model (SEM) is used to construct a structural model of way finding. The result indicates that factors influence the degrees of difficulty in way finding are: the local environmental information, and the individual familiarity of space. Among these factors, the local environmental information is the major factor in pedestrian way finding. Pedestrian way finding is influenced by direct factors as well as indirect factors of the local environmental information.
