The casualties caused by emergencies increased rapidly in recent years, more and more scholars began to make an intensive study of this field. From the subjective judgment to objective measurement it is a new attempt to use the visualization software to study the knowledge base, development context and recent research with the downloaded data from the database such as "Web of Science". Based...
In this paper, we study the adaptability of pedestrian route recommender systems to panic behaviors in smart space networks. Due to environmental unsafe conditions, under panic, people may exhibit herding and stampeding behaviors. To achieve efficient and safe pedestrian transit, these behaviors should be prevented. Our approach to this issue is based on finding critical network areas where personally...
Modeling of crowd and pedestrian dynamics has intrigued engineers, physicists, and sociologists alike, even in recent times. Scientists have long sought to model the collective motion of large groups of individuals and study the mathematical basis of what seems to be apparently random behavior. A large number of macroscopic models have been proposed that describe crowd motion as a whole, much like...
In this paper, we model passengers' panic during a ship fire by considering its most influential factors. The qualitative factors are quantified, allowing us to study passengers' panic in a probabilistic manner. Considering the time-varying nature of these factors, we update the state of the factors over time. We utilize a dynamic Bayesian network (DBN) to model passengers' panic, this allows us to...
As for the emergency evacuation issues under the circumstance of unexpected disasters, based on the analysis and comparison of existing evacuation models, this paper puts forward a new occupant evacuation model. This model introduces quantitative formula which reflects people's tension degree in panic into social force model, and it takes into account the influence of individual's mass behavior to...
Public incidents not only lead to great loss to human life and property, but also cause psychological changes of people, which probably trigger public panic, stimulate derivative events and even produce greater disaster. Internet technology makes the transmission of information more quickly, with the negative impact even more serious. This paper analyses the causes, characteristics and response of...
This article is based on the idea of lowering the risk of taking erroneous decisions under stress or panic. There are many environments in which wrong decisions may cause severe problems; good examples are airplane control or nuclear power plant monitoring. The crucial issue is to detect the point of transition from a well-thought decision into a decision taken under stress. Sensors support monitoring...
