In recent years, landscape designs have been widely noticed because the quality of life has been one of main concerns for people. However, there are not many quantitative evaluation methods of landscape. Main purpose in this study is to present a quantitative evaluation approach of bridge landscape in relation to image-impression, i.e. Kansei. Firstly, the overall complexity of landscape including the bridge and its backgrounds is measured using the fractal dimension. Then, some interrelationships among image-impression, fractal dimension and several attributes such as color phase, construction locations, structural types and viewpoints are clarified by the Rough Set Theory in order to evaluate bridge sceneries in landscape design.
