Study On The Spatial Effect Of Hefei Rail Transit Station

Through the development of the urban underground transportation space,the major cities explore the way of emancipating the space and alleviating the urban congestion.Urban underground rail traffic,that is,the subway,is the most important part of urban underground transportation.Since the first subway has been built in 1965,about 28 cities have been approved to operate,build and plan the subway.As the capital city of Anhui Province,Hefei opened the first subway line in 2016,and so far two lines have been put into use.The cross line form of Hefei rail transit has been basically mature,and the subway has gradually become one of the important transportation ways for the citizens to travel.The subway station space includes two parts: the ground and the underground.The most of the ground space in the subway station is the subway station with a radius of 400 meters.The underground space in the subway station area refers to the underground construction part of the subway station.The domestic research on the metro station space is becoming more and more perfect and rich with the expansion of the subway development scope.Based on the Hefei Metro Line 1,line 2 along the site to conduct field research,describe around the site planning and construction characteristics,summarized the classification and distribution of line 1,line 2 subway stations along the line,grasp the impact of opening traffic in Hefei city from the macro level.On this basis,the questionnaire survey was conducted to investigate the way,frequency and scope of the citizens' travel before and after the opening of the subway,and to explore the impact of subway opening on the life circle of the citizens,and to calculate and quantify the changing range of the livelihood circle of the city.In order to investigate the impact of different stations on Hefei Metro Line 1 and line 2,the paper investigates the impact of different stations on the subway station and the terminal station.Besides,by investigating the way of the public to the starting station and the destination from the terminal,the paper discusses the demand of the public for different geographical locations.This paper analyzes the status quo of the ground floor space of the subway station area under different distribution characteristics,and summarizes the problems and optimization directions of the underground space in the subway station area under different distribution characteristics.With the subway station on the surrounding area map and space distribution function image,to explore the influence of the surrounding area of the subway users,and then explore the impact of different stand points of underground space atmosphere and underground space on the subway crowd behavior characteristics,for the domain of underground space for the subway station to lay the foundation for sample selection and research.The research on underground space of subway station is mainly carried out through two angles of user's visual behavior and action characteristics.Influence of underground space in subway station domain research on crowd visual behavior,the selection of Hefei representative sites for filming,with the underground space development of the city subway photos mature of eye movement experiment,analysis of the impact of the subway station and the distribution of underground space on human visual elements produced a variety of visual behavior,combined with the current Hefei subway station underground space atmosphere problems explore the future direction and method of optimization.By using research methods of behavior measurement,recorded the weekday traffic peak,non peak traffic day and weekend three while the underground space of crowd behavior and comparative analysis,to explore the underground space with the elements that influence people in different periods,and through the establishment of a number of people with time varying image changes in different periods using the crowd summed up different distribution characteristics under the law,discuss the rationality of the underground space.Through the investigation of underground space in Hefei subway operation and the subway station on the ground,the initial grasp of the current situation of Hefei rail transit development and existing problems,and through the eye movement experiment,behavior measuring station space visualization study direction and method of optimization of underground space in Hefei subway station ground,use the crowd behavior,providing a certain reference for the design of Hefei city and the other in the space station construction and to be constructed.
