Perception and Evaluation of Street Space Quality in Puntoon Community,Guangzhou
摘要
Abstract
Guided by the concepts of"New Vitality for Old Cities"and"People's Cities"in Guangzhou,this study found that renewing old communities requires a balance between preserving the cultural context and meeting the demands of modern life.The Puntoon Community in Guangzhou,as a micro-renovation pilot project,faces many issues.These include redefining the boundaries between public and private spaces in the street areas during the transformation process.This is a typical case for research as the study integrates image-recognition technology with visualized stated preference to construct a research framework of"physical feature recognition preference model construction utility optimization",providing a quantitative approach to enhancing the quality of community street spaces. The study collected a total of 368 street-view images of 21 streets in the Puntoon Community,taken from the perspective of pedestrians.Semantic segmentation was conducted by combining the PSPNet model and the ADE20K dataset.Visual features were quantified using the K-means clustering algorithm,and eight evaluation elements,including walking safety and color richness,were categorized into distinct levels.Based on this,a visual SP questionnaire was designed,and 327 sample data were analyzed using the mixed logit(MXL)model.The findings revealed that color richness(RI=17.16%)and interface transparency(RI=17.13%)were the core visual elements that influence preferences,followed by social activity and spatial comfort;facility convenience had the least impact.Subgroup analysis indicated that residents were more interested in social functions,and tourists were more sensitive to facility convenience and spatial comfort.The study classified streets into three types through utility evaluation:T1,T2,and T3.T1 streets have insufficient pedestrian safety and attractiveness.T2 streets lack facilities and greenery.T3 streets need to improve interface transparency and social vitality.Hence,some targeted improvement measures are proposed,including implementing traffic diversions and adding social spaces in T1 streets,optimizing the signage and greenery in T2 streets,and enhancing social scene creation in T3 streets.After the renovation,the space utility of the streets significantly improved. The subjective and objective integrated evaluation systems in this study provide a quantified basis,based on user preferences,for renewing streets in old communities.In the future,it can further promote the sustainable renewal of blocks by combining residents'emotional needs with community cohesion.关键词
