Influence of Road Landscape Elements on Comfort Evaluation

Abstract

There are two possible ways to improve the comfort of road users. The first is a method of improving the flatness of the road surface besides the performance of the vehicle and the other method of improving the landscape performance seen while driving from the vehicle. From the viewpoint of maintenance of the road administrator, it is desirable to have more choices. However, it is costly to improve the flatness such as cutting overlay. It is necessary to consider measures to make it possible to select more cost effective maintenance management measures. In this study, as a measure for improving landscape characteristics, we examined how comfort during driving will be affected by changes in road components such as road structure, existing slope, planting and so on. We conducted an evaluation experiment at the time of driving on existing road, Hakone turn-pike. Then, we analyzed the relation between road components and evaluation using Quantification Theory I. Then, it was confirmed that the slope surface shape, the slope surface / planting condition, the road alignment, etc. had an influence on the evaluation.
