Abstract: According to the requirements of green highway construction, six aspects including safety, econo-my, environment, energy consumption, technology and demonstration are proposed. The evaluation index system of 6 first-level index and 20 second-level index is introduced. Then, according to the characteristics of the green highway construction project and the determined index system, the evaluation model is established by combining the analytic hierarchy process with the fuzzy comprehensive evaluation method, which has guiding significance for the development and construction of the green quality highway and can provide ref-erence for the route optimization of the green highway.

Keywords: Green highway; Route optimization; Evaluation index
