Abstract
In this paper, the landscape with a mountain road was interpreted from a new viewpoint of composition of nature and road. From this viewpoint, relation between perceptual process and landscape evaluation was revealed. For this, perceptual process of roadscape elements was analyzed by a tachistoscopic experiment, Landscape evaluation with a mountain road was analyzed by a SD method experiment. Major finding are as follows: 1. Roadscape with cut slopes or retaining walls resembled nature visually, was evaluated highly. 2. Roadscape with road structures united with road visually, was also evaluated highly. The former is existing finding and the latter is new finding. These results showed clearly attributed to the viewpoint.
