Key Points

  • The aim is to improve the accuracy of assessing traffic risks in mountainous tunnel groups using a dual-model approach.
  • Utilized the improved CRITIC method for indicator weighting to enhance objectivity.
  • Implemented the extension matter-element model alongside set pair analysis for dual verification.
  • Conducted case studies to validate the integrated evaluation system.
  • The new approach accurately determines tunnel safety levels.
  • Verified that the evaluation system is reliable for developing risk prevention measures.
  • Showed that combining models leads to better consistency with actual tunnel conditions.

Abstract

The improved CRITIC method significantly enhances the objectivity of indicator weighting, making it more consistent with actual tunnel conditions. The combined application of the extension matter-element model and the set pair analysis model form a complementary dual verification mechanism. Case studies verified that this integrated evaluation system can accurately determine tunnel safety levels and provide a reliable basis for developing targeted risk prevention and control measures.
