A Study On The Urban Transport Accuracy And Spatial Differentiation From The Perspective Of Microcirculation

For a long time,the main driving force of urban development in traffic city,traffic problems is also the focus of scholars.This paper studies the livability of urban traffic in Xi'an from the perspective of microcirculation,and analyzes its spatial differentiation characteristics.At present,there are still some related research in China.In the research content,this paper takes the streets of Xi'an City as the basic unit,mainly through the resident subjective traffic demand data and Xi'an objective traffic supply data comparison,to analyze,to more accurately grasp the status of traffic land use in Xi'an,Facilities and spatial law,and then according to its law,aims to Xi'an traffic microcirculation supply and demand summary,the future planning and improvement of transport facilities to provide practical advice,but also on other similar domestic urban traffic problems Provide a valid reference.In the research methods,this paper mainly uses literature analysis,analytic hierarchy process,social survey method,Arc GIS spatial analysis method,descriptive statistical method and empirical research method.The specific use of these methods is as follows: on the one hand,through the social survey method to obtain Xi'an city traffic microcirculation livability subjective data;the other hand,through the Xi'an Municipal Public Security Bureau Traffic Authority and the Xi'an Municipal Transportation Bureau on the Xi'an City traffic situation announcement and the Xi'an Bureau of Statistics "2016 Xi'an Statistical Yearbook" to provide the data,while the use of Xi'an remote sensing images and Xi'an traffic map digital,access to Xi'an city traffic objective data.And then use SPSS statistical analysis software for factor analysis,cluster analysis and correlation analysis.And then with the help of Arc GIS software to obtain the data and statistical analysis of the results reflected in the space.Finally,the paper analyzes the present situation and the improvement measures of the traffic microcirculation in Xi'an,and makes a conclusion on the comparative analysis and comprehensive analysis of the subjective and objective supply data.The results and conclusions are as follows:(1)At present,the internal traffic arrangement of Xi'an is not reasonable,among which the street area along the second ring and the third ring is the area that needs to be improved.(2)The traffic classification of Xi'an is: Conditions are not convenient and congested streets,mainly between the Second Ring and the Third Ring Road,the overall characteristics of the population is relatively dense but the public transport,including subway configuration is insufficient;traffic conditions convenient and non-congested streets,they are less and scattered,Mainly in the tricyclic,and basically within the scope of the existing subway coverage;despite the traffic conditions are convenient but the overall congestion more serious streets,their relatively large number and mainly concentrated in the Second Ring Road and the second ring within the city center area;Although the traffic facilities are not convenient but the residents travel is not congested streets,such streets are mainly distributed in the tricyclic outside the subway along the development of slower areas;subway on urban traffic convenience greater impact.(3)Xi'an public transport system is mostly in accordance with the distance to the center of the city to configure the distance,making a lot of street traffic in Xi'an a lot of convenience;(4)such as railway stations,passenger stations and other areas of huge traffic(5)Xi'an fast rail transit transfer inconvenient phenomenon,affecting the residents of their use of satisfaction;(6)large-scale residential community and the residents of the street residents of the public transport demand is not enough attention,(7)different types of large-scale community of subjective commute convenience evaluation is very different,more comprehensive function of large-scale residential community subjective commuter convenience evaluation than the urban community, High,the function of a single large residential community subjective commuter convenience evaluation is very low,in addition to promoting employment-living integration of space development model,you can consider trying to promote street system.
