Sequencing The Urban Roads Construction Based On Entropy Weighting, Grey Relation Analysis And TOPSIS

Along with rapid economic development of China and expansion of cities, the supply of infrastructures can't meet the demand of people in cities, especially the urban transportation infrastructures. Therefore, huge funds are being invested into the construction of urban transportation infrastructure in many cities, which involved a lot of different projects. However, how to arrange scientifically the construction order of these projects can make sure a maximum benefit in the short term and the sustainable benefits in the long term, which need to be considered particularly.This paper is aimed to research sequencing the urban roads construction.Firstly, the paper analyses the present situation and problems on sequencing the urban roads construction at home and abroad, and introduce some methodologies in this field.Chapter III, IV and V are the core parts of this paper. In chapter III, the paper established both the assessment systems of road construction and node importance based on the methodologies of node importance and area location; in chapter IV, the paper calculates the weighing via entropy and AHP firstly. Then, the paper evaluates wholly the urban road projects by applying for the methods of TOPSIS and grey relational analysis, and gets an elementary building list; in chapter V, the paper classifies and evaluates the elementary outcome, then decides the final building list of the urban roads projects.Finally, the paper makes use of the model on the case of primary road in Beijing. The fact shows that the model is scientific and reasonable. I hope the model can help improving existing evaluation system more or less.
