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...

Shashi Shekhar Qingsong Lu, and Sangho Kim AHPCRC-UM The goal of evacuation route planning is to identify routes that canbe used to minimize the time required to move vulnerable populations to safe destinations. Evacuation route planning is a key component of effective disaster emergency management and homeland defense preparation. As such, it is an important challenge facing the U.S. Army, whi...

In an emergency situation (e.g., tsunami, chemical spill, fire) it may be necessary to displace people to safer locations. Evacuation plans must be prepared so that these movements are properly organized. Based on the ACO (ant colony optimization) meta-heuristic we design a computational model to optimize a multi-objective path-finding associated to an evacuation planning problem. The results a...

Route Evacuation Planning is the science of ensuring the safest and most efficient evacuation time of all expected residents of a building, city or region, or transportation carriers (e.g., train, ship, and airplane) from a treat or actual occurrence of a hazard (e.g., natural disasters, traffic, industrial, or nuclear accidents, fire, viral outbreak, etc.) [1]. In any scenario (i.e., building,...

We introduce an open-source software Aamks for fire risk assessment. This article focuses on a component of Aamks – an evacuation simulator named a-evac. A-evac models evacuation of humans in the fire environment produced by CFAST fire simulator. In the article we discuss the probabilistic evacuation approach, automatic planning of exit routes, the interactions amongst the moving evacuees and t...

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...

When a natural disaster occurred, some roads cannot be used anymore and sometimes blocked. Also, survivors and refugees cannot follow the evacuation procedures by just using default maps after disaster. A previous study proposed a safety route guidance system that can be used after natural disasters by using participatory sensing. The system estimates safe routes and generates an evacuation map...

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 ...

Evacuation route planning is one of the most crucial tasks for solving massive evacuation problem. In large public places, pedestrians should be transferred to safe areas when nature or man-made accidents happen. A multi-objective ant colony algorithm for massive pedestrian evacuation is presented in this paper. In the algorithm, three objectives, total evacuation time of all evacuees, total ro...
