In the study, characteristics of pedestrian emergency response were summarized from their general performance and influencing factors. The parameters from three distinct aspects (psychology, physiology and behavior) were comprehensively considered to design the experimental scheme. The simulation experiment system was constructed to collect and evaluate the dynamic changes of emergency response when pedestrians face traffic risks. In the experiment, virtual reality technology was applied to simulate the traffic risk scenarios, and participants were recruited to experience walking on virtual urban roads. Equipped with monitoring devices, the instant heart rate data and external behavior of participants were collected. Moreover, subjective perceptual questionnaires related to risk profiles were supplemented before and after the experiment, functioned as auxiliary analysis to realize the quantitative assessment of the emergency response. The results reveal the individual and overall change of pedestrian emergency response in different traffic risk scenarios. Overall, this study attempts to propose a new insight on the aspects such as personal emergency response capability, environmental facility setting, traffic safety management, etc. Suggestions for improvement are proposed from the perspective of personal emergency response capability, environmental facility setting, and traffic safety management.
