The international universal calculations of the time for evacuation have their own features and limits and their effective areas have to be noticed. This study analyzes different ways to calculate the evacuation time, according to the relative indexes and rules for evacuation of Chinese sports stadium. According to the specific calculation in a university, it has safety hazards. On condition of...

In the case of emergency situations, robotic systems can play a key role and save human lives in recovery and evacuation operations. To realize such a potential, we have to address many scientific and technical challenges encountered during robotic search and rescue missions. This paper reviews current state-of-the-art robotic technologies that have been deployed in the simulation of crowd evac...

The core idea of integrating the treatment of lane reversals and crossing elimination in evacuation network design is illustrated by the examples in Figure 1, which show how controlling lane entries and turning movements at intersections can create uninterrupted flow conditions for specific evacuation paths. The intersections must be expanded into subnetworks, as shown in Figure 2, to model an ...

Finding the optimal clearance time and deciding the path and schedule of evacuation for large networks have traditionally been computationally intensive. In this paper, we propose a new method for finding the solution for this dynamic network flow problem with considerably lower computation time. Using a three phase solution method, we provide solutions for required clearance time for complete ...

Hospital evacuations that occur during, or as a result of, infrastructure outages are complicated and demanding. Loss of infrastructure services can initiate a chain of events with corresponding management challenges. This report describes a modeling case study of the 2001 evacuation of the Memorial Hermann Hospital in Houston, Texas (USA). The study uses a model designed to track such cascadin...

In order to design a reasonable pedestrian evacuation and exclude the security risks in large stadiums, this thesis proposes the research of security model of evacuation in stadiums combined with multi-agent and cellular automata. The research is based on cellular automata model and the process makes extended analysis to the cell’s behavior of autologous, and then it makes simulation experiment...

We propose an approach to compute navigation instructions on mobile devices carried by people during a building evacuation in order to guide them to safe areas or exits. The mobile devices form an ad hoc network via local communication links and use this network to collect information about the current evacuation situation. This information is used for path planning in order to optimize escape ...

On 30 May 2008, the Government of the Netherlands informed the national parliament about the effectiveness of preventive evacuation of coastal and river areas in case of flooding. Analysis of a case study showed that it is impossible to evacuate coastal areas preventively within a 48-hour time span preceding a worst credible scenario flood caused by a storm surge. This fact illustrates the need...

In creating an evacuation simulation for training and planning, realistic agents that reproduce known phenomenon are required. Evacuation simulation in the airport domain requires additional features beyond most simulations, including the unique behaviors of firsttime visitors who have incomplete knowledge of the area and families that do not necessarily adhere to often-assumed pedestrian behav...

Evacuation modeling is an important problem that has been intensively studied in the last 40 years. In a general evacuation situation, there might be more then one safe place. A common approach to reduce this multidestination problem to a single destination problem is to connect all safe places via zero cost links to a super sink. However, this approach works only as long as the safe places hav...
