Due to the occurrence of secondary disasters in disaster relief, a swarm-based dynamic disaster evacuation simulation model is established to settle the practical difficulties of reducing efficiency in evacuation. And much better simulation results have been achieved than static plans or disorganized autonomous escape scheme. Simulation results show that "to changing the status quo" dynamic eva...

Evacuation performance is crucial for gymnasium design and occupant safety. This paper uses Simulex, an agent-based model to simulate and optimize the evacuation performance of a typical medium-size university gymnasium. Simulated results show that the current design is susceptible to evacuation problems, such as long egress time, insufficient exits and severe imbalance for stair usage. Design ...

INTRODUCTION On 24 September 2005, Hurricane Rita made landfall in eastern Texas, resulting in the mandatory evacuation of 16 counties and declaration of disaster areas in 22 counties afterward. HYPOTHESIS This study tested whether the evacuation and hurricane landfall affected the pattern of Texas poison center calls. METHODS Texas poison center calls received from the 22 disaster-area cou...

INTRODUCTION The evacuation of a health care facility is a complex undertaking, especially if done in an immediate fashion, ie, within minutes. Patient factors, such as continuous medical care needs, mobility, and comprehension, will affect the efficiency of the evacuation and translate into evacuation resource needs. Prior evacuation resource estimates are 30 years old. METHODS Utilizing a c...

Evacuation planning is a fundamental requirement to ensure that most people can be evacuated to a safe area when a natural accident or an intentional act happens in a stadium environment. The central challenge in evacuation planning is to determine the optimum evacuation routing to safe areas. We describe the evacuation networkwithin a stadium as a hierarchical directed network.We propose amult...

An effective evacuation system can help people escape from building fire. Most evacuation systems consist of an indoor positioning system, a back-end database, and a display device with calculation and display software. However, very few of them can smartly determine which evacuation route is the best decision. If all the locations of the evacuating people can be simultaneously determined, the ...

BACKGROUND Safety of evacuation is of paramount importance in disaster planning for elderly people; however, little effort has been made to investigate evacuation-related mortality risks. After the Fukushima Daiichi Nuclear Plant accident we conducted a retrospective cohort survival survey of elderly evacuees. METHODS A total of 715 residents admitted to five nursing homes in Minamisoma city,...

In metropolitan areas, a potentially large number of pedestrians depend either on transit or other modes for evacuation, or need to walk a distance to access their passenger cars. In the process of approaching some designated pick-up points for evacuation, the massive number of pedestrians may incur tremendous burden to the vehicles on the roadway network. Thus, an effective coordination betwee...

The understanding of evacuation processes is important for improving the effectiveness of evacuation plans in the event of volcanic disasters. In terms of social processes, the enactment of evacuations in volcanic crises depends on the variability of individual/household responses. This variability of population response is related to the uncertainty and unpredictability of the hazard character...

Researcher: Xiaoqing Deng Title: AN AIRCRAFT EVACUATION SIMULATION BASELINE USING DES FOR PASSENGER PATH PLANNING Institution: Embry-Riddle Aeronautical University Degree: Master of Science in Aeronautics Year: 2016 This paper introduced a Discrete Event Simulation (DES) model that simulates passengers’ evacuation paths and decision-making processes during aircraft certification. The model was ...
