Research On Transportation Pattern And Station Layout Allocation Of Intercity Railways

With the deepening of regional economic integration and the acceleration of urbanization,the urban agglomerations passenger traffic is faced with new opportunities and challenges,and the demands of the traffic networked and modernized are growing up.As the inter-city railway has the characteristics such as regional,inter-city nature and the transit type operation,it has become the most important way of the urban agglomerations passenger traffic development.Thus,within the background of the inter-city railway big scale construction,combining with the experiences at home and abroad of the inter-city railway construction and operation,this paper clarifies the function of inter-city railway furtherly,discusses the reasonable speed target and transportation organization mode,and studies the station layout and rational allocation of facilities and equipments,which has important practical significance for guiding future inter-city railway construction and drafting operation management.This paper includes several parts as the following shows:Clarifying the function of inter-city railway furtherly.Firstly,this paper analyses the concept of the inter-city railway.Then,this paper analyses the basic elements of the inter-city railway function from four aspects like line network status,targeting people,service scope,service quality.Lastly,combining with our countries'urban passenger traffic characteristics,based on the urban agglomerations inter-city railway development plans in our countries,this paper makes a comprehensive analysis of our countries'inter-city railway function.Studying on the inter-city railway speed target.Firstly,this paper clarifies the main principle of the inter-city railway speed target selection,then according to the idea frame of the inter-city railway speed target selection,with the analysis from several aspects like project investment,the speed target coordination of nearby network,operating costs and economic benefits,attracting passenger flow,this paper finally determines the reasonable inter-city speed target.Studying on the inter-city railway transportation organization mode. This part includes the cross-line passenger flow and the original line passenger flow transportation organization mode.For the cross-line passenger flow,there exists two modes as operating cross-line train and transferring,firstly,this paper analyses the influencing factors,then discusses the advantages and disadvantages of the two modes,lastly,conducts the research of the operating mode of the cross-line train.Regarding the original line passenger flow,firstly,this paper classifies the operating mode of the original line train,then,this paper analyses the influences of the overtaking mode with speed difference to the inter-city trains in different aspectsStudying on the inter-city station layout selection and rational allocation of facilities and equipments.After analysing the inter-city station type,this paper summarizes the inter-city railway station layout plans according to the differences of train operation type,the relative position of lines and platforms,and the line laying patterns,then it proposes the suggesting construction standards of the inter-city railway station design.Lastly conducting a research with inter-city railway example.Within the discussing scope of Foshan west station to Guangzhou south station in the Guangzhou-Foshan circle line,this paper carries out a detailed analysis of the example from several aspects including inter-city railway function,speed target selection,transportation organization mode,station layout selection and allocation of lines.
