Study On The Planning Of Wuhan City Circle Intercity Railway Network

As the rapid development of economic globalization,so does the urbanization process in our country,leading to the rapid development of city extension.It breaks the restrictions of administrative divisions,forming a phenomenon common development between several cities.Therefore,a number of urban agglomerations formed,which are representative highly developed regions.As well as a substantial increase in the number of residents travel on the travel service level requirements,our group began the planning and construction of the city and even the City Circle intercity rail network.Therefore,scientific and rational development of urban agglomerations intercity rail has become an important research topic.In this background,this paper taking Wuhan city circle as the research subject,from the analysis of characteristics of Wuhan city circle inter-city rail network,traffic analysis,measuring scale,plan layout,the evaluation of Wuhan city circle for five steps such as planning study systematically.Firstly,from definition,intercity railway passenger flow characteristics,function orientation in the face of the inter-city railway has carried on the basic research,summarizes the major world urban agglomeration,and inter-city railway transportation development present situation and prospect of domestic urban agglomeration are analyzed,and then clear the definition of Wuhan city circle,and comparative analysis with other cities of Wuhan city circle characteristic;Then,according to the collected data,the article analyzes the traffic volume of Wuhan city circle,using per capita travel frequency method and regression model method to predict the total passenger travel,using the gravity model method to predict the trip distribution of passenger flow OD table;Online network scale,the first systematic analysis of the four categories of network measurement methods,and to determine the reasonable scale of measurement method is suitable for urban agglomeration's inter-city rail network,such as demand analysis and analogy method,the level of services and then use these methods to measure the scale of Wuhan city circle inter-city railway network and summarizes the analysis;In terms of layout method,firstly analyzes the planning layout of the target and principle,and then summarizes and analyzes the current main use of the layout of the method,including the elements of point,line and plane analytic hierarchy process(AHP),the function such as analytic hierarchy process(AHP)method,and detailed analysis of the wire mesh network form in the early development stage and the different characteristics and shape,on the basis of established planning ideas,and from the urban space,urban axis,tightness of wire mesh nodes,three aspects are analyzed in detail the layout characteristics of Wuhan city circle,and then from the perspective of different wire mesh structure,planning out of the three different in Wuhan city circle line network layout scheme;In project evaluation,from the practical,not coincidence,feasible perspective,established the evaluation system of the rule layer,from the line network structure,the operating effect,practical,social benefits and strategic development of five aspects,such as chose 16 indicators,combined with expert analytical hierarchy process(AHP)method to determine the index weight,finally using comprehensive satisfaction for three schemes of decision research.
