The publicity of urban space is closely related to its economic and cultural value. However, accurate quantitative analysis of publicity is still lacking. Even space syntax lacks consideration for Realistic Operation of Traffic Nodes. In contrast, the Urban Network Analysis (UNA) method takes into account the traffic nodes, the building function and other factors, and makes the quantitative description of the publicity of urban space more reasonable. With UNA, this study used accessibility as the main index, and took Nanjing City of China as a case to analyze the publicity of urban space. The research was based on the big data of urban buildings and Traffic road structure. And the analysis result was verified with Urban Heat Map of Tencent. The result showed the effectiveness of the UNA in the quantitative analysis of urban spatial publicity. And the analysis method can be widely used in urban planning and research.
