Research On Evaluation And Promotion Method Of Old City Street Separation Interface Under The Background Of Urban Renewal

Under the background of urban renewal in the new era,street renewal designs are springing up everywhere.In order to meet the demand of green travel in urban renewal and construction,as well as the requirements of street design guidelines and relevant government policies,the urban street separation interface deserves extensive attention.This paper focuses on the current situation of street separation interface,aiming at providing scientific methods and design ideas for the design of street separation interface in old cities of China.In the past,the treatment of the related elements of the old city street separation interface was based on the simple experience of street construction in the past,and lacked the consideration of the overall angle of streets.In this paper,the concept of street partition interface is put forward,and the unified research on the spatial interface formed by partition facilities elements that divide different traffic spaces in the street is mainly focused on the setting and design of street railings and road partition belts.Motor vehicle lanes,non-motor vehicle lanes,pedestrian lanes and buildings are separated from each other by a street separation interface to define different functional areas of streets.This paper summarizes the current problems and development opportunities faced by the street separation interface in urban renewal design,and puts forward the principles and ideas of upgrading the planning and design of the old city street separation interface.Taking Beijing Exhibition Road block as an example,this paper summarizes the current situation of street separation interfaces in the block through investigation,and analyzes the functions,settings,distribution and main problems of various separation interfaces.On the basis of summarizing and analyzing the current situation of the street separation interface in the exhibition road block,an evaluation system of the street separation interface is established,and the overall evaluation of the street separation interface is carried out by taking the safety,legibility,environmental protection,comfort,service,economy and intelligence of the separation interface as evaluation indexes.To evaluate the current situation of the separation interface of each street in the block and provide scientific basic analysis for the improvement of the separation interface.From the macro level of the block,the upgrading plan of the street partition interface is carried out,and the spatial distribution of the partition interface in different upgrading directions at the block level is proposed.From the micro-level of streets,the upgrading design of street separation interface is carried out.Based on the evaluation of separation interface,demonstration streets are selected to study the upgrading strategy and method of separation interface.For designers and management departments to give guidance in the design of street separation interface,to provide pioneering methods and ideas for the renewal of urban streets.In the future,with the deepening of the renewal and construction of streets in the old city,apart from overcoming the current problems,the street separation interface is more likely to play a variety of roles such as the city's haze prevention interface,sponge channel,belt ecological space,belt leisure space,intelligent street interface,etc.,further improving the well-being and enjoyment of urban residents,and promoting the construction and improvement of urban renewal.
