Building the Evaluation Scale for View from a Motorway

Abstract

At present, the scale for the landscape design of a roadway has not been setup or systematized efficiently and not reflected on social needs. The purpose of this study is to build the evaluation scale for a driver to feel an amenity and safety, which is significant in the landscape design of a motorway. The research was conducted to identify the landscape elements of the view from a motorway and to analyze how these elements would affect a sense of amenity and safety while driving. As a result, it turns out that the main elements that consist of the view from a motorway are the structure of cross section (side grade and surface material) and road alignment (length of sight), and the evaluation scale that is simply marking these two elements is established. The evaluation scale was confirmed the validity, and examined for application to design for the roadway.
