Research On Street Space Optimization Based On Comprehensive Evaluation Of Physical Environment

With the transformation of China’s development stage,the people’s demand for a better life is growing,from pursuing the speed and scale of urban development to the concern and demand for urban space quality.As one of the outdoor environments under the influence of urban spatial form,the physical environment plays a decisive role in the quality of outdoor space.Traditional urban design often emphasizes economic interests and spatial aesthetics,ignoring the quality of urban space.As a kind of urban space,street space bears the most extensive activities of people.Therefore,it is especially important to improve the quality of street space.Therefore,supporting the design of street space city based on physical environment simulation is an effective way to improve the quality of urban space.However,the existing research is mostly based on a single physical environment factor,and the multi-factor comprehensive analysis needs further research.This paper focuses on the comprehensive simulation evaluation and optimization methods of multi-physical environment elements.The article mainly studies the following contents:Firstly,the existing research on the physical environment is summarized and summarized,and the characteristics of each single physical environment,the selection of simulation software,the setting of relevant parameters,the evaluation criteria and the coupling relationship with the spatial form are clarified.Secondly,the method of conducting climate environment research and physical environment satisfaction survey in the target area is proposed,and the improvementrequirements of the physical environment of the street space in the target area are clarified.By dividing the research area into the overall and key regional levels,the “standard area ratio” is used as the evaluation index,and the selected physical environment elements are weighted according to the importance,and a comprehensive simulation evaluation system of the physical environment is established.Research and develop optimization principles and optimization methods to construct a “conditional cycle optimization process based on physical environment comprehensive simulation evaluation” to optimize street urban design.Finally,taking Futing Street in Weifang City as an example,through analyzing the local climate characteristics and the physical environment needs of Futing Street,it is determined that wind,sunshine and noise are the key targets,and the initial scheme of traditional urban design techniques is comprehensively simulated.Evaluation,there are many problems in the discovery program.Based on the evaluation results,the spatial form is adjusted by “street city design comprehensive evaluation and street space optimization method”,and the scheme is optimized by adding auxiliary measures such as sound barrier and greening.After repeated evaluations – optimization process Form an optimized solution.After comparing the physical environment of the scheme before and after optimization,it is proved that the physical environment of the optimized scheme has been significantly improved,and finally the physical environment of the Futing Street urban design scheme has reached a comprehensive relative optimal state.
