An Improved Comprehensive Evaluation Method of Road Passenger Transportation Safety

Carrying out safety assessment before the departure of road passenger transport vehicles can find hidden dangers and prevent accidents. This article discusses the determination of the safety evaluation index of the transportation process, and the construction and improvement of the evaluation method. After analyzing the participating factors in the accident, the relevant factors affecting the safety of the transportation process are obtained. The main influencing factors were analyzed and combined with the principal component analysis method to analyze and filter the importance of the influencing factors to determine the safety evaluation index. Based on the comprehensive evaluation method, the road passenger transportation process safety evaluation method is constructed. Aiming at the problem of the inconsistency between the evaluation results of the traditional evaluation method and the actual input in the actual application, the reasons for the problems were analyzed and an improved comprehensive evaluation method was proposed. The improved evaluation method was applied to verify an accident instance, and the results showed that the improved evaluation method solved the problem of the deviation between output and input in the traditional evaluation method, and could objectively reflect the impact of various factors on the safety of the transportation process.
