Research on Evaluation of Construction Organization Plan of Reconstruction and Extension of Expressway Based on Fuzzy Comprehensive Model

In order to conduct a comprehensive and systematic evaluation of the construction organization plan of the current expressway reconstruction and expansion operation area, an evaluation index system based on project implementation factors, traffic operation factors, economic benefit factors and environmental impact factors is proposed, using the analytic hierarchy process (ahp) to calculate the weight of each index, fuzzy comprehensive evaluation method was used to construct the construction organization plan evaluation model, The construction organization of ground layer in the reconstruction and expansion project of Jihe Expressway is analyzed as an example. The research shows that the results can be used to evaluate the construction organization plan of expressway reconstruction and expansion, which has scientific applicability and provides a new idea for the comprehensive evaluation of the construction organization plan of the reconstruction and expansion operation area.
