Abstract
Recently in Japan, many bridges have been built with deliberate consideration on landscape and aesthetic aspects. There are several measures for landscape prediction but no effective tool has been developed for landscape design of a bridge form. The authors have been developing a prototype of comprehensive computer aided design(CAD) system for visual design of a bridge form. In this study, the authors have been developed the system for analyzing visual impact of a bridge and making zone map of view area. in order to support planning a bridge in landscape. Visibility, view angle, distance between view point and a bridge and angle of incidence which consists of vertical and horizontal components are analyzed in this system. And from these result making zone map of view area is feasible.
