Evaluation And Optimization Of Space Environment Of Subway Station Entrance In Qingdao Old City

Due to the advantages of high speed,large traffic volume,safety and comfort,urban subway has developed rapidly in recent years and gradually plays a leading role in public transportation in big cities.Subway can effectively alleviate urban traffic congestion and improve passengers’ green travel experience,especially in the old urban areas where urban space is limited,community facilities are aging and historical features are gathered.Subway plays a huge role in guiding the expansion of urban space form and improving urban landscape environment.As the only channel for passengers to get in and out of the station,the subway entrance and exit play the role of "connecting the preceding and the following" as a whole.It is not only the transition space between the subway station space and the urban aboveground space,but also an important node for the exchange and circulation of various elements in the urban space.Subway entrances and exits should not only echo the design of underground space environment,but also integrate with the urban space environment.In order to clarify the influencing factors of subway entrance and exit space environment in the old city,and provide relevant basis for urban managers to make subway entrance and exit planning and design and construction decisions,this paper first summarizes the research results and shortcomings of subway entrance and exit space in the old city at home and abroad,based on the development status of urban subway in China and the further improvement of the suitability requirements of subway entrance and exit space environment To reveal the necessity of environmental optimization design strategy of subway entrance and exit in the old city.Secondly,this paper defines the research background and significance of the entrance and exit space environment of Qingdao metro station in the old urban area,and expounds the relevant concepts of the optimization of the entrance and exit space environment of Qingdao metro station in the old urban area;thirdly,from the perspective of residents and passengers,this paper uses the analytic hierarchy process to determine six first-class evaluation indexes,including safety,convenience,practicability and aesthetics,and takes them as an example This paper constructs the evaluation system of spatial environment index of subway station entrances and exits in the old urban area of Qingdao,and uses the evaluation system to evaluate the entrances and exits of four representative stations in the old urban area,such as Qingdao station and Renmin Huitang station.Finally,according to the evaluation results,the paper puts forward the targeted optimization strategies for the current situation of the entrance and exit space environment of the subway station in the old city of Qingdao,and tries to deepen the theoretical understanding of the entrance and exit space environment of the subway station in the old city of Qingdao.The main conclusions are as follows:(1)On the whole,the evaluation system can better reflect the advantages and disadvantages of each index of import and export,and can provide a very useful reference for the formulation of targeted optimization strategy.It can be used for reference before the planning and construction of the subway station entrance and exit in the old urban area of Qingdao,and can also be used for evaluation and optimization after the construction.(2)As a transportation hub,Qingdao metro station has higher requirements for the efficiency,convenience and guidance of the entrance and exit.The entrance and exit of the subway people’s Hall station are satisfactory in terms of safety,practicability,efficiency,guidance and aesthetics,and need to be further improved in terms of convenience.(3)The optimization of the space environment of subway station entrance and exit in the old city mainly focuses on changing the passageway ladder into a permanent ramp to improve the traffic efficiency,transforming the surrounding green landscape design to improve the aesthetics,and optimizing the public transport connection to improve the convenience..
