The Timing of Urban Rail Transit Construction Based on the Weighted Gray Correlation

In order to clear rail lines of the construction of the timing, the need for each line analysis and evaluation of scientific and rational manner, thus forming a good construction planning program. Analysis of the impact of rail transit construction timing factors, and presented its quantitative methods; further established based on the weighted gray correlation of urban rail transit construction methods and sequence the steps to solve the model. Finally, an example of Xi'an rail transit network in the timing of the construction. The results show that the proposed method using the results of the same order with the actual construction, the method is simple and has good application prospects.
