Optimization Research On Street Space In Central District Of City Based On The Pedestrian Perspective

As an important part of urban public space,street is the important place to stimulate city's vitality and participate in social activities for the public.The role which street plays in the city attracts more attention of all,"People-oriented" street design becomes an urgent need.However,Urban road construction in our country,is affected by the traditional planning model and the concept of “Car-oriented” for a long time.It just pays attention to cars,ignores the pedestrians and pedestrian traffic,thus brings problems,such as imbalance of street scale,lack of security,decrease of space quality,loss of vitality and so on.Motor vehicle parking which can be seen everywhere on the street,and fragmentation of walking space have brought threats to travel safety of pedestrians and non-motor vehicles seriously.In fact,pedestrians are the main users of the street.The ultimate purpose of the city traffic is serving and transfering human beings by using a variety of traffic tools.Therefore,It's necessary to rethink the existing planning and construction model,to reexamine the roles,which street plays in city development.This paper takes street space in central district of city as the research object,and comprehensively uses methods of literature study,comparative study,case study and so on.By exploring the optimal design of street space from the perspective of pedestrians,so as to realize transformation from traffic road to living street.The article is divided into five parts.The contents of the first part include research background,the theories and practices of city street design and the research purpose and meaning.According to the thought of “problems-analysis-resolution” to organize the study structure and framework.The second part: By observing the pedestrian behavior characteristics and activities on the street to analyse the relationship between street environment and pedestrian activities,summarize the actual demands of pedestrians for the street space and provides basis for street space optimization.The third part: Comparing the present situation on city street construction at home and abroad.Summarizing the development trend and drawing lessons from foreign experience on city street construction,such as European and American.Through investigation and research,Summarizing and analyzing the present situation,the existing problems and the related reasons on street construction in our country.The fourth part: Exploring the optimal design of street space from the perspective of pedestrians.Putting the safety of the pedestrians in the first place on the street design.Througha series of strategies and methods to improve and create the street environment,which gives priority to walking.Putting forward four kinds of improved strategy from the macroscopic angle and specific optimization design methods from the microscopic view.Discussing and summarizing in details from aspects such as the street section,the street intersection,the street interface and so on.Reducing the speed of cars on road and intersection through refinement and humanized designs,to improve the security and comfort of street environment and create a complete street space.The fifth part: Making instance analysis through the urban design optimization case of Guangzhou Pazhou,west area.Discussing the specific application of strategies and methods on city street space optimization,combining the theory with practice,and providing reference for other cities.
