Abstract:

The evaluation of service level of expressway network system is a multi-objective comprehensive evaluation problem. In this paper, by taking the supervisors of expressway system as the appraiser and the expressway system as the objective, a two-level comprehensive evaluation model for service level evaluation is established based on the analytic hierarchy process （AHP） and the fuzzy comprehensive evaluation （FCE） method. Then, the evaluation indices are determined and the weights of the indices are obtained by means of the single-rule AHP method. Moreover, the membership functions of the indices are developed, a suitable fuzzy evaluation model is selected, and a method to determine the evaluation results according to the evaluation aims is put forward. An numerical example indicates that the proposed method is suitable for the evaluation of service level of expressway system in operation.

Key words: traffic engineering, expressway, service level, fuzzy comprehensive evaluation
