The Research Of Technical And Method On Network Structure Analysis For Urban Rail Transit

The network structure analysis technology of urban rail transit has important guiding significance to the scientific planning of rail transit network.This paper first analyzes the basic characteristics of the single line(radial line,radius line,ring line,main line)of rail transit,the influence on passenger flow and operation and the applicable conditions of urban spatial form.The optimal length model of single line is put forward to consider the factors influencing the length of the line considering the cost of construction,the number of train lines,the operating cost and the passenger flow income.Secondly,the complex network theory is used to establish the topology model under the network P space of different development stages in Beijing,Shanghai and Guangzhou,and the variation law of the characteristic value of the complex network in the process of network development is analyzed.Then,The paper analyzes the relationship between the transfer efficiency of the network structure and the transfer coefficient of the actual operation network,and sums up the different network structure pairs The Influence Law of Transfer Coefficient of Network Operation.Finally,in the analysis of the coordination of urban rail network layout and the coordination of urban spatial structure,the paper reveals the interaction between the two and the interaction law.Static coordination mainly analyzes the consistency of urban rail transit network layout and urban land use,employment and population distribution,and puts forward the coordination degree between the rail transit network site and the city public center,the layout of the rail transit network and the distribution of the urban population in the orientation On the consistency of the rail transit network layout and location characteristics of the three indicators of quantitative evaluation index;dynamic coordination is mainly on the rail transit network generation process and the coordination of urban spatial evolution process analysis,including three aspects :the different development period of the network scale and social and economic coordination of discrimination in the summary of the development of domestic rail transit more perfect on the basis of the law of urban development,the use of spatial structure of the population,The data to determine the development of urban rail transit network ahead or lag.
