Research on Highway Green Construction Attribute Evaluation Based on Similarity Weight Theory

Through analyzing the elements of the highway green construction,the index system of highway green construction evaluation was established.Based on the method of determining indexes weight by using simil-arity weight principle,attribute recognition model for evaluating highway green construction was constructed using principle of attribute recognition theory.At last,the model was verified combined with practical engineering.The result shows that the attribute recognition model can evaluate highway green construction system effectively and objectively.
