Abstract

Based on the AHP-TOPSIS method, a safety evaluation model of parallel escape lanes on mountainous expressways was established. The AHP method was used to classify and aggregate the related factors affecting the safety of parallel escape lanes, and a safety evaluation index system of target layer, criterion layer, and index layer was established. By using the “1–9 scale method” and combining expert opinions, the weights of single-layer indexes, comprehensive weights, and comprehensive weight sequences were determined. The close degree between the evaluation scheme and the positive ideal solution was calculated by the TOPSIS method, and the corresponding relationship between the close degree and the safety grade of parallel escape lanes at five levels was given. Based on the design results of three parallel escape lanes, the evaluation model was applied to evaluate its safety level, and improvement measures were proposed.
