Abstract

For the sake of preventing the negative stress reaction of subway passengers and improving the active stress response ability, the process and characteristics of subway passengers' stress reaction were studied experimentally and theoretically. A subway car environment was created. Data on heart rate and blood pressure of the passengers were obtained for the density of 1 persons to the density of 10 persons. The mean blood pressure and heart rate were taken as the control variable of point mutation. The stress state was taken as the state variable. A cusp catastrophe model was built for the subway passenger's stress reaction. Finally, a qualitative fitting analysis and a quantitative fitting analysis were carried out. The results show that the passengers' emotion begins to perturb with the increase of population density, and then changes to the point position, and becomes emotionally excited, and then they will slowly adapt to the increase of population density and return to emotional stability, and that the stress reaction of subway passengers accords with cusp catastrophe model. © 2019 China Safety Science Journal.
