Model for Social Impact Post-evaluation of Highway Based on Factor Analysis and Success Evaluation Methods

In view of the complexity of social impact post-evaluation and relatively inefficient evaluation methods, this paper constructed an index system of social impact post-evaluation of the highway through a combination of inductive and deductive methods based on the analysis of literature surveys and expert surveys and made full use of the superiority of the factor analysis and the advantage of success evaluation in data processing to establish a model for social impact post-evaluation of highway, which was testified by a case study. The model finds out a feasible path to solving complexity and inaccuracy of existing index systems, which are always involved with unavailability of useable data in the social impact post-evaluation of highway.
