| Along with the increasing development of national economy, the unceasing expanding of the urban scale and the increase of the owned cars, the problem of urban traffic congestion is getting worse and worse, urban rail transit system is being mentioned since the common public transportation cannot meet the demand of the growing passenger flows. Urban rail transit system is an important traffic system of the urban public passenger transit. It is very important for us to plan the network of urban rail transit for alleviating the problem of traffic congestion, sharing public passenger flows, and reducing environmental pollution.Based on the actual situation of the planning and construction of urban rail transit, according to the experience of domestic and international rail transit network planning, this paper makes a study on the urban mass rail network panning whose main line is the urban rail transit mode and the characteristics of line network structure, the interactive relationship between urban rail traffic planning and urban development and the interactive relationship between urban rail transit and the comprehensive transit.First of all, this paper makes a statement of urban rail transit for the function orientation and role analysis, then it makes an analysis of the urban rail transit mode and network structure of domestic and international cities. The planning ideas and methods are put forward by the discussing of the urban rail transit network planning from two aspects of macro and micro angles.Secondly, the paper analyzes the influence on urban construction and development by urban transit rail and the interaction relationship between urban space layout and urban rail transit. Quantitative calculation and analysis are made for the developing status of Xi'an space structure by using Roxy index model. Larry model is used to explain the relationship between the land use and the population distribution, which is to state the interaction between the urban land use, the population distribution and urban rail transit.Next, in order to reflect the real demand of urban traffic passenger flow and catch the developing trend of urban transit better, this paper starts a study on the interaction relationship between comprehensive transit and urban mass rail network planning. It explores the effect from the multiple perspectives, multi-layered aspects on the aviation and port hub, railway hub, inter-city railway, public passenger transport hub, urban roads and public transportation, travel mode of residents and tourists, so as to integrate urban rail transit with other components of comprehensive traffic net to be urban comprehensive traffic system which are mutually intertwined and interlinked.Finally, exampled by urban rail traffic construction of Xi'an City, based on the actual case analysis, this paper makes a research of the interaction relationship between urban rail transit and space layout, urban land use, population distribution, urban comprehensive transit in Xi'an City. |
