Abstract
The purpose of the present study is to clear the relation of visual disorder and regularity to physical situation in the central business district. So we grasped visual effects in street views and then extracted elements that we had perceived as disorder and regularity. Then we cleared the relation between elements and their situations. We got following results : (1) Disorder is decided by distribution form and impression of disorderly elements. Regularity is influenced by physical situations of not only regular ones but also disorderly ones. (2) Disorder and regularity in street views are decided by mutuality of physical situations of individual elements.
