Analysis of Walkability of Historical Blocks of Shanghai Old City Area Based on Spatial Syntax

The improvement of walking environment quality can effectively alleviate the traffic pressure of the city, which is conducive to the environment construction of the low-carbon city. The measurement of the pedestrian environment is an important premise of urban planning and construction, and an important indicator to measure social ecology and pedestrian safety. From the perspective of spatial syntax, this paper selects four parameter values, namely connection value, global integration degree, local integration degree and comprehensibility degree, to quantitatively analyses the spatial structure and road network characteristics of blocks, and to explore the walkability of blocks from the topological structure itself. The empirical research object is Shanghai Old City area, which is the cradle of Shanghai-style culture and the window to show the historical accumulation and traditional culture of Shanghai to foreign tourists. Through the research and analysis, it provides a theoretical basis for further optimizing the walking experience of historical districts and updating the planning and design of road space.
