Research on the Establishment and Application of a Transportation Safety Supervision Evaluation System Based on Grey Analytic Hierarchy Process

Given the increasing complexity of transportation systems and the critical need for effective safety oversight, this study aims to evaluate and improve the transportation safety supervision (TSS) system in Henan Province, China. Based on questionnaire data from relevant units in Henan Province, China, a three-level index system of the effectiveness of TSS consisting of 4 criterion-level indicators and 25 factory-level indicators is established. By combining the analytic hierarchy process (AHP) and grey system theory, a hierarchical grey evaluation model is constructed to evaluate the current situation of TSS in Henan Province. The results show that the evaluation index system and the weights of each index are reliable. The comprehensive evaluation value of the TSS system in Henan Province is 3.08, indicating that the effectiveness of the system is at level 2; thus, the current situation of TSS in Henan Province is good. Based on the calculated evaluation values of the first- and second-level indicators, suggestions are put forward to strengthen the management of the TSS by supervision units at all levels.
