Abstract
In Asian nations, which have reached high economic growth in recent years, development of urban transport infrastructure has been progressing rapidly. Because it is closely connected to urban life, it is important to build a transport infrastructure that has an appropriate balance between the function and quality of an urban environment. As typical developed and developing countries, Japan and China are facing the same problem in relation to streetscapes. In this study, considering the similar points in many ways such as culture, population, transportation infrastructure, etc., the target areas of Chengdu, China, and Tokyo, Japan, were selected and a questionnaire on familiar narrow streets was conducted in both places. The similarities and the differences of sensitivity on the streetscapes in Japan and China were understood with Wilcoxon test. Following that, conditional inference trees method was used to analyse the data obtained from the survey. It revealed that beautiful buildings play a positive role in the comfort and beauty of streetscapes while the bad pavement of sidewalk has the negative affect on the comfort and the beauty of streetscapes. On the aspect of affinity, in Tokyo, the quantity of shops has a positive affect and in Chengdu, the beauty of buildings plays the positive role. Besides those, the presence of obstacles effects the walking strongly both in Tokyo and Chengdu. Such fundamental knowledge revealed in this study will be a salutary lesson for the streetscape development.
