道路走行時の快適性に景観構成タイプが与える影響

抄録

Improving comfort when driving on the road is an important aspect of customer satisfaction. There are a wide range of factors related to comfort. In this study, all roadscape components on expressways were considered as roadscape composition type, and the effects of these types on comfort were determined. Specifically, we used the roadscape composition type as explanatory variables and the results of the comfort questionnaire as objective variables, and analyzed them using Quantification Theory 1, adding considerations based on partial correlation coefficients and category scores. Along with considering the influence of each roadscape composition type on comfort based on partial correlation coefficients and category scores, the number of roadscape composition type and the size of roadscape composition type were also found to affect comfort. Even roadscape composition type that are not highly comfortable (e.g., falling object prevention fences) can be expected to improve comfort by improving their shape and color.
