Based on an AHP-FCE model, an evaluation method for expressway E&M system operation state is proposed. The evaluation system of E&M system operation state is constructed, and three evaluation indexes, i.e. functional serviceability rate, timely repair rate and replacement repair rate, are extracted by using equipment maintenance data; the weight division of each evaluation index is completed in conjunction with AHP algorithm; an FCE model of expressway E&M system operation state is established, and the operation state evaluation is achieved finally. The analysis results show that the system state evaluation method proposed in this paper can gain an insight into the operation state of E&M system, find out systematic potential safety hazards in time, and provide theoretical support for highway maintenance work.
