Abstract

In order to ensure safety of regional railway transportation and improve its comprehensive management level, safety situation of regional railway transportation was characterized through accident multi-attribute analysis, a characterization indicator system of situation assessment was established and corresponding quantitative methods were presented. Then, an improved TOPSIS-Cosine Similarity assessment model based on combined weights was constructed from levels of relative distance and relative trend, and parameters concerning accident grade and nature were preliminarily estimated. Finally, a real-life case study was carried out according to statistical accident data in a certain region of China from 2016 to 2018, and effectiveness of the model was verified by two sets of comparative tests. The results show that the proposed method can reasonably characterize safety situation of regional railway transportation, and evaluate its pros and cons as well as its fluctuation degree from relative distance and relative trend, thus providing a basis for its safety management decision-making. © 2019 China Safety Science Journal
