A Study on the Perceptual Evaluation of Public Space Around Elevated Areas from the Perspective of Inventory Renewal

After the incremental wave of rapid urbanisation, managers, designers and users have to face the re-evaluation of spatial quality and spatial vitality. In the era of stock renewal, the multiplicity of road forms and the vitality of road space have brought greater challenges to the problems of stock development and urban renewal and triggered the academic community to pay attention to the rational use of public space around elevated. Elevated bridges are an important result of incremental planning, and the comfort of space is an important practice to meet the demand of stock planning. In this paper, we extract a typicalised scenario of urban elevated space, and simulate the impact of urban elevated on the thermal comfort of the surrounding public space through environmental diversity maps. At the same time, we investigate the use of eye-tracking and SD evaluation methods to construct a perceptual evaluation system for public spaces around elevated spaces. The goal of this study is to make a scientific exploration for enhancing the vitality of elevated peripheral public space, and also to provide a reference for the future development of cities towards elevated spaces.
