Research On The Evaluation Of Public Space Vitality Of Suzhou High-Speed Railway New Town Based On Big Data Analysis

Since 2008,when China's first beijing-tianjin-hebei intercity railway was put into operation,China's high-speed railway has developed rapidly.Due to the huge economic benefits brought by the beijing-tianjin-hebei intercity railway and the unprecedented concentration of people,many cities have taken the opportunity to join the high-speed railway construction army,so as to promote the economic development of the city and evacuate the huge people in the old city.However,many new high-speed railway cities under construction are not as dynamic as "empty cities" and "ghost cities".Governments and departments pay close attention to these problems and try to find solutions.With the continuous development of city information at the same time,the rise of big data acquisition and analysis technology and its application is gradually changing people's way of life and habits of thinking,in the near future big data technology will be used to explain all kinds of urban phenomenon,and gradually infiltrated some disciplines,such as the urban planning,urban design,in order to improve people's rational city planning and design problems and management issues and the ability of the city.In this paper,based on the above research background,attempts to start from the angle of urban public space vitality,draw lessons from predecessors to high-speed rail metro related theory and urban public space dynamic research,put forward the high-speed new city public space vitality evaluation system by big data analyzing,at the same time take Suzhou high-speed railway new city public space as the empirical research.In order to improve in the future high speed rail new city public space dynamic aspects,this paper provide some reference and advice.The whole study is divided into three parts:Part ?(chapter 1,chapter 2)basic theoretical research.By reviewing previous definitions of urban public space,relevant theories of high-speed railway new city and researches on public space vitality,this paper defines the public space of high-speed railway new city.This paper describes the vitality of public space in the new high-speed railway city,expounds the technical composition of big data and the advantages brought by its application in urban management and urban design.Part ?(chapter 3)construction of evaluation system.This paper mainly points out the shortcomings of the traditional public space evaluation system,analyzes the factors that affect the public space vitality of the new high-speed railway city,and divides the public space vitality of the new high-speed railway city into three levels: material environment,spiritual needs and crowd activities through the analytic hierarchy process,thus constructing the public space vitality evaluation system of the new high-speed railway city.Part ?(chapter 4)empirical research.Firstly,the high-speed railway new town in Suzhou is selected as the research object,and the factors in the evaluation system are analyzed by big data analysis method,the score of vitality evaluation of Suzhou high-speed railway new town was obtained by AHP high-speed vitality evaluation and analysis the specific public space vitality performance of Suzhou high speed rail new city in the physical environment,population,of the spiritual demand,finding out the current Suzhou high speed rail new city public space the cause of the lack of vitality.Secondly,comparing the vitality evaluation system of big data with the traditional vitality evaluation system,it is found that compared with the traditional public space vitality evaluation system,the public space vitality evaluation system based on big data analysis has the advantages of broader perspective and more accurate data.Again according to the Suzhou high speed rail new city public space vitality evaluation results and the evaluation index weight,this paper divided the index factor into four types,and giving vitality optimization suggestions :puts forward the key to optimize factor "high attention-low satisfaction",continue to maintain "high attention-high satisfaction" factor,gradually to promote "low interest-high satisfaction" and "low interest-low satisfaction" factors.And then introduces the specific operating mode and technical guidance.
