A spatial analysis approach to evacuation management: shelter assignment and routing
نویسنده
چکیده
Evacuation planning requires an integrated analysis of heterogeneous spatial datasets including population, road network and facilities. It is a complex and challenging task to delineate evacuation circumstances and make reasonable connections among the datasets which evacuation management of emergency situations will be based on. An evacuation management system requires an easy configuration by evacuation managers who do not necessarily have full knowledge of Geographic Information Systems (GIS) but need to understand the situation promptly and provide decisive instructions that can be fulfilled only when they can manage datasets and develop new workflows in various scenarios. A spatial analysis platform provides toolkits for spatial data acquisition and processing, analysis, and visualisation from/to online open sources. Such toolkits built in typical GIS software are utilised in this paper to show the feasibility of enabling users to manage spatial data and customise their analysis by combining common data analysis tools to meet their requirements in evacuation planning. Case studies are provided to demonstrate the usability of these toolkits in Brisbane flood evacuation management.

Evacuation Simulation with Limited Capacity Sinks - An Evolutionary Approach to Solve the Shelter Allocation and Capacity Assignment Problem in a Multi-agent Evacuation Simulation
We heuristically solve an evacuation problem with limited capacity shelters. An evolutionary learning algorithm is developed for the combined routeand shelter-assignment problem. It is complemented with a heuristic method for the fair minimization of shelter capacities. Different behavioral assumptions “fair” vs. “globally optimal”) are investigated. The proposed approaches are discussed in the...
متن کاملEVACUATION SIMULATION WITH LIMITED CAPACITY SINKS An evolutionary approach to solve the shelter allocation and capacity problem in a multi-agent evacuation simulation
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...
متن کاملAn Integrated Simulation of Tsunami Hazard and Human Evacuation in La Punta, Peru
The 2011 Great East Japan earthquake and tsunami was a magnitude 9.0 Mw event that destroyed most structural tsunami countermeasures. However, approximately 90% of the estimated population at risk from the tsunami survived due to a rapid evacuation to higher ground or inland. Thus, tsunami evacuation is the most effective measure to reduce casualties. In this paper, we applied a new developed e...

Evacuation and shelter in place are two common protective action measures during hazardous events that involve the release of hazardous materials. These responses are complex and require advanced planning to determine their appropriateness to reduce human exposure to hazardous materials and minimize related health risks. Evacuation and shelter in place responses were assessed for people in the ...
