Abstract
To revitalize local areas and tourism using the landscape resources in community, Scenic Byways have been built since 2007 in Japan. In this study, we analyzed the regional characteristics of sequential road landscape using the image features (fractal dimension, sky share, green share) of photographs taken at 20-m intervals on the Scenic Byways of Hokkaido and Kanto. The structural (urbanization level, vastness level, forest level) and fluctuation (short-term fluctuation of landscape, contrast of nature and urbanization, contrast of land and forest, fluctuation of skyline) characteristics of the sequential landscapes were evaluated from the average values and the power spectrum density of image features, respectively. In comparison of the Scenic Byways of both regions, the Hokkaido route is vast and monotonous, while the Kanto route is forested, urban and fluctuating. In addition, the sequential landscapes were classified into five clusters based on their structural and fluctuation characteristics, and then the features of each cluster were evaluated.
