Abstract: In order to accurately and effectively evaluate the safety of railway passenger transportation, railway passenger transportation safety evaluation system was constructed. Subjective weight was determined by AHP, objective weight was determined by the entropy method, the subjective and objective weights were combined, and game theory was used to calculate the comprehensive weight, the weight proportion of each influencing factor was determined, and the cloud model was used to evaluate railway passenger transportation safety. Take a train station S as an example, according to the actual situation of S station quantization index, the cloud model was used to evaluate it. The research results show that the factors that affect the safety of railway passenger transportation account for a relatively large proportion of factors such as the safety of equipment design and use, the harsh natural environment and social security, and corresponding measures need to be taken to prevent problems before they occur. At the same time, the feasibility of the combined weighting cloud model in the safety evaluation of railway passenger transportation is verified.
