Many fire evacuation models have been proposed in recent years to better simulate such as an emergency situation. However most of them do not respect a recommendation of fire evacuation experts regarding the fact that evacuees should follow the boundaries of obstacles or wall to find the exits when their visibility is limited by smoke. This paper presents an agent-based evacuation model with Sm...

Large-scale controlled evacuations require emergency services to select evacuation routes, decide departure times, and mobilize resources to issue orders, all under strict time constraints. Existing algorithms almost always allow for preemptive evacuation schedules, which are less desirable in practice. This paper proposes, for the first time, a constraint-based scheduling model that optimizes ...

Emergency situations involving a large number of people may develop into disasters. One example of such emergency situation is fire evacuation in a building or crowded area. Although crowd evacuation simulation has been an active research area for many years, little research focuses on simulating the evacuation process with a Leader-Follower Model which shows the role of leaders in the evacuati...

It’s an important evaluation architecture safety standards about personnel emergency evacuation under the fire condition, from the development trend of university gymnasium, it’s relatively rare that based on comprehensive evaluation the multi-functional gymnasium fire conditions personnel emergency evacuation study and there is no mature evaluation model can be applied to practical operation l...

Title of Dissertation: AN INTEGRATED OPTIMAL CONTROL SYSTEM FOR EMERGENCY EVACUATION Ying Liu, Doctor of Philosophy, 2007 Directed By: Professor Gang-Len Chang Department of Civil and Environmental Engineering How to effectively control evacuation traffic has emerged as one of the critical research issues in transportation community, due to the unusually high demand surge and the often limited ...

The present study aims to conduct a quantitative evaluation of evacuation route safety using the Ant Colony Optimization (ACO) algorithm for risk management in central Tokyo. Firstly, the similarity in safety was focused on while taking into consideration road blockage probability. Then, by classifying roads by means of the hierarchical cluster analysis, the congestion rates of evacuation route...

5 Evacuation planning and scheduling is a critical aspect of disaster management and national security applications. This paper proposes a conflict-based path-generation approach for evacuation planning. Its key idea is to decompose the evacuation planning problem into a master and a subproblem. The subproblem generates new evacuation paths for each evacuated area, while the master problem opti...

In this paper, we consider the route coordination problem in emergency evacuation of large smart buildings. The building evacuation time is crucial in saving lives in emergency situations caused by imminent natural or man-made threats and disasters. Conventional approaches to evacuation route coordination are static and predefined. They rely on evacuation plans present only at a limited number ...

Road transportation networks are a segment of society’s critical infrastructure particularly susceptible to service disruptions. Traffic incidents disrupt road networks by producing blockages and increasing travel times, creating significant impacts during emergency events such as evacuations. For this reason, it is extremely important to incorporate traffic incidents in evacuation planning mod...

Emergencies, especially major ones, happen fast, randomly, as well as unpredictably, and generally will bring great harm to people's life and the economy. Therefore, governments and lots of professionals devote themselves to taking effective measures and providing optimal evacuation plans. This paper establishes two different emergency evacuation models on the basis of the maximum flow model (M...
