In this paper, we set up a communication model of passengers for the metroemergency. In the model, four categories of passengers are definedas unknown passengers, supportive passengers, neutral passengers and opposed passengers. Three passengers’ characteristics are taken into account, such as spreading desire, the trustworthinessand the passengers’ uncertainty about their opinions. From thesimulation results, we can see that the passengers’ uncertainty about their opinions has a positive correlation with the time ofpassengers’ opinions reaching consensus, while other two factorsboth have a negative correlation. The result is useful for metroofficials to guide and control emergency information.展开更多
