| The rapid growth of the city’s rapid economic development and population, resulting in urban traffic problem becomes more and more serious. Urban rail transit with its large capacity, fast, safety, environmental protection and other advantages, has become the first choice to solve the traffic problems. At the same time, the urban rail transit project is investment in large scale infrastructure construction projects, the development and construction will directly affect the sustainable development of the city, so the urban rail transit project benefit evaluation of scientific significance. The key to correctly evaluate the benefits of urban rail transit project lies in whether we can establish a set of evaluation index system and a scientific and reasonable evaluation method.The construction of city track traffic project, brought to the city is not only the traffic efficiency and the economic efficiency, more important is the social benefit and environmental benefit. The comprehensive benefit of city rail transit project is the organic combination of the transportation benefit, economic benefit, social benefit and environmental benefit. This article from the four aspects of traffic benefit, economic benefit, social benefit and environmental benefit and comprehensive benefit of urban rail transit project system analysis and evaluation.This article first discusses the background and significance of topics, domestic and foreign research present situation, research content and research ideas; secondly, the theory related to the comprehensive benefits of urban rail transit projects are introduced, expounds the concept about the comprehensive benefits of urban rail transit project, characteristics and structure; third, the design principle of comprehensive benefit evaluation indexes of Urban Rail Transit Based on the project, the construction of evaluation index system of comprehensive benefits, to define the specific meaning of indicators at all levels, give out the quantitative value method of different index(mathematical model method, the expert scoring method), and dimensionless method of index values were standardized processing using linear; fourth, a calculation model is established combined weight level analysis and based on the entropy method, and the comprehensive benefit of the evaluation methods for the study of using the Hilbert index space vector evaluation model; finally, in the N city of X subway line route selection decision as an example, the comprehensive evaluation model is applied to practice. |
