抄録

China has become the world’s second largest economy after recent rapid economic growth. On the other hand, the urbanization of China has aggravating the problems of air pollution, traffic congestion, and the dual structure of urban and rural areas. Therefore, the Chinese government has implementing a policy to revise the efficiency-oriented city planning to the quality-oriented, namely “National new urbanization plan”. We conducted a questionnaire survey on streetscapes in Chengdu, China. In this survey, we asked pedestrians and bicycle users about the streetscape during traffic. We applied AIM (Adaptive Index Model) method [1] to analyze this survey data. We used the estimated AIM results to score the satisfaction of the streetscape based on “production rules”. As a result, safety was important for each traffic, and street cleanliness and the number of bicycle parking lot was important for cyclists. Moreover, Satisfaction was low in the school district and the vicinity of parks. On the other hand, the streets were highly satisfied in the shopping district.
