Research on the health evaluation index system of the street space in the old city

Purpose. Healthy street space is an important goal in achieving public health, and street space in old areas is a design object to promote urban renewal. In 2021, China’s urbanization reached 65.22% according to Development and Reform Commission of PRC (2023). The rapid development of urbanization leads to urban problems and public health events that threaten residents’ life safety and physical health in old urban areas. Health issues are a major problem faced in urban renewal. Methodology. In this paper, an index system for evaluating the health of urban streets is established through empirical research. Through the preliminary study on the scope of data acquisition and establishing an index system. The authors identified and weighted eight main and 15 secondary indicators. By asking experts, residents, and tourists and using the information entropy-based weight allocation method, we determined the weight of each indicator. An empirical study of the Dongmenkou area in Yiyang City then followed this. Results. The study results show that the street space in the Dongmenkou district of Yiyang City has problems regarding inappropriate street width, imperfect street greening, poor street safety at night, and uneven distribution of facilities. Suggestions are made to improve the street scale, street environment, and facilities.
