Survey of Urban Spatial Quality Research under New Data and New Technology Environment

Urban public space is an important part of citizens' lives, and its environmental quality has an important impact on citizens' activities and behaviors. During the epidemic, both the citizens and the government are more fully aware of people’s desire to enjoy urban public spaces and the importance of the environmental quality of these spaces. At the same time, researchers are aware of the need to build more multi-dimensional, large-scale and Accurate methods for measuring the quality of urban public space, and the establishment of a system that can detect and feedback the quality of urban space in real time, and carry out precise control of urban public space on weekdays and in the case of possible outbreaks. Traditional quantitative research on the quality of urban public space is limited by technology and data sources, mostly small-scale questionnaire surveys and costly and time-consuming. In contrast, the application of some new technologies and new data can bring this situation different. This article summarizes, analyzes and reviews new technologies represented by machine learning, virtual reality, physiological sensors, eye tracking, etc. and new data represented by multi-source city data that have emerged in recent years. Analyze the possibility of more precise analysis and more intuitive presentation of these new technologies and new data in research methods, and propose the possibility of these new data and new technologies to innovate existing research paradigms, and how they can better help research The author responds to basic questions in the fields of architecture, urban design and landscape - how do people perceive and use space, and to what extent and how does the physical space environment affect people's perception and behavior?
