Present Situation and Prospect of the Research on the Public Space Design of Subway in China

Subway public space is an important activity place for urban residents, which has the particularity and complexity of space. This paper summarizes and analyses the previous research on the design of urban subway public space in China from the aspects of research perspective and method, design principle and optimization strategy. The results show that: The current research has formed a relatively complete research system, and the research perspectives are diversified, covering the analysis of subway public space elements at the micro level, the special design of space composition at the meso level, and the composite design of macro level and urban space. The research methods are quantified, modelled and visualized. And put forward the prospect of future research, enhance the comprehensive research perspective; introduce the concept of ecological green; deepen the humanized design; construct a more perfect typed research system and expand the distribution range of research objects; research methods should promote interdisciplinary integration, improve research paths, and improve the accuracy of data acquisition and analysis.
