Research on optimal design strategy of urban public space based on GIS and spatial behavior analysis

With the acceleration of urbanization, the design and optimization of urban public space have become the key to improving urban quality and residents’ quality of life. This study explores the optimal urban public space design strategy based on GIS (geographic information system) and spatial behavior analysis. The research background lies in the problems of low efficiency, single function and traffic congestion in urban public spaces. Through GIS technology, the spatial analysis of urban public space is carried out. The residents’ usage habits are understood by combining spatial behavior analysis, and the optimization design strategy is put forward. The experimental results show that after optimizing the spatial layout, the use efficiency of public space increased by 25%; the functional configuration increased in leisure and entertainment areas, and the average daily flow of people in public spaces is increased by 40%. Improved traffic organization, reduced congestion points, and improved the accessibility of public space by 30%. This study confirms the effectiveness of GIS and spatial behavior analysis in the optimal public space design. It provides the scientific basis and practical guidance for future urban public space design and transformation.
