Research On The Method Of Urban Agglomeration Inter-city Rail Network Layout

The rational distribution of Inter-city Rail Transit network layout in urban agglomeration determines the performance of the Transportation System in the whole area. It affected transportation structure, the rail volume trip, the travel time, in urban agglomeration. It also affected the urban agglomeration land-use pattern and sustainable development of society,economy and environment. So ,we researched the layout of IRT network should be scientific, objective and carefully analysised impact factors to IRT network layout. According to urban agglomeration transportation structure,it defined the reasonable layout pattern and the rail channel position.Referring to the characteristic of such qualitative analysis in IRT network layout, an algorithm of traffic location in urban agglomeration Inter-city Rail Transit Network Distribution is presented, according to the city's comprehensive transportation importance search out the initial route network, and then accordance with the predicting the OD and the actual situation to revise the initial network.,the recommended network is given. At the same time,according to the economic interaction within the urban agglomeration strength to determine the level of traffic lacation line of inter-city, and in that level to establish the construction sequence, and finally with Wuhan City Group line network for example checking the layout method of rationality and effectiveness.This method shows a quantitative analysis for the network layout.
