Aging-friendly Evaluation and Optimization Strategy of Public Space in Old Residential Areas: A Case Study of Suojincun Street in Nanjing

In recent years, the number of elderly people in China has been growing, and the problem of population ageing has been aggravated. The problem of population aging has aggravated by the fact that the quality of life of the elderly has become the focus of social attention. Most of the elderly in China mainly live in old neighborhoods, and improving the living space for the elderly is the key to improve the quality of life of the elderly. This study is based on the Suojincun street in Nanjing, and combines fieldwork and questionnaire survey methods to analyze the problems in renovating old neighborhoods from three aspects: transportation, greening and activity space. The research reveals several challenges in the aging of old residential areas, including disorganized internal traffic, limited green spaces with subpar quality, inadequate attention to needs of the elderly for activity space, underutilization of certain areas, and a lack of functional facilities.Based on the design principles of ageing community renovation, corresponding community optimization strategies are proposed, in order to provide certain reference and guidance for similar designs, so as to promote the development of residential areas for the elderly and improve their sense of well-being.
