A novel approach is proposed in this paper for personnel and vehicle iterative evacuation optimization to tackle crowd evacuation problem in emergency. The paper analyzes the mechanism to coordinate people flow evacuation with traffic stream evacuation, and explores optimization model from a personnel and vehicle coordination evacuation perspective. The evacuation is classified as two categorie...

One of the necessary measures of saving human life in emergency situations, such as fires, is the safe and swift evacuation of people. The prerequisites for this are to anticipate, identify, and eliminate factors preventing people from leaving buildings in a timely and safe manner while moving them to a safe place [1]. The occurrence of errors caused by engineering, design, human, and psycholog...

Evacuation has the potential to save lives, but could be costly in time, money, and credibility. Evacuation is a possible measure in case of a threat for flooding. Different types of evacuation can be distinguished as preventive evacuation, vertical evacuation to safe havens or shelters or shelter in place. The consequences in terms of loss of life depends on the required time related to the ty...

Evacuation models can be used to determine evacuation capacity, by estimating the time required for evacuating populations to leave areas exposed to a hazard. Disaster management practices and evacuation modeling are generally carried out to prepare for ‘worst-case’ conditions. However, hazard severity is highly variable. Performing evacuation modeling for multiple hazard scenarios may provide ...

Wildfire evacuation trigger points are agreed-upon prominent geographic features (e.g., ridges, rivers, and roads) used in wildfire evacuation practices, and when a fire crosses these features, an evacuation is recommended for the communities or firefighter crew in the path of the fire (Cook, 2003; Cova et al., 2005). Spatial modeling of wildfire evacuation triggers has used fire-spread modelin...

Protective actions for hurricane threats are a function of the environmental and information context; individual and household characteristics, including cultural worldviews, past hurricane experiences, and risk perceptions; and motivations and barriers to actions. Using survey data from the Miami-Dade and Houston-Galveston areas, we regress individuals' stated evacuation intentions on these fa...

background: to compare the efficacy of two routes of prostaglandin e 2 administration (intravenous and intramuscular) for treatment of missed abortion this study was conducted. regarding the pilot cases of missed abortion admitted for termination of pregnancy intravenous administration of pge2 that had higher efficacy compare to intramuscular route, investigators designed this study. methods: i...

We use visual analytics to assist human experts in the verification of evacuation schedules and enable them to identify the bottle-necks in building evacuation. The user can change parameters, such as the number of occupants present in the rooms, the parametric settings for fire simulation, the building design, etc. and analyze their effect on evacuation. Visualization of the people flow in the...

Multiobjective evacuation routes optimization problem is defined to find out optimal evacuation routes for a group of evacuees under multiple evacuation objectives. For improving the evacuation efficiency, we abstracted the evacuation zone as a superposed potential field network (SPFN), and we presented SPFN-based ACO algorithm (SPFN-ACO) to solve this problem based on the proposed model. In Wu...

To better understand household hurricane evacuation decisions, this paper addresses a limitation to existing hurricane evacuation modeling aspects by developing a dynamic model of hurricane evacuation behavior. A household’s evacuation decision is framed as an optimal stopping problem where every potential evacuation time period prior to the actual hurricane landfall, the household’s optimal ch...
