Vehicle Routing for Emergency Evacuations
… challenges of planning transit-based, regional evacuations. First, a variant where evacuees arrive at constant, location-specific rates is introduced. In this problem, a fleet of capacitated buses must transport all evacuees to a depot/shelter such that the last scheduled pick-up and the end of …

Analytical model for staging emergency evacuations
Disaster response in areas of high population density is centered on the efficient evacuation of people and possibly goods. Developing evacuation plans suitable for different levels of urgency based on the intensity of threat is a challenging task. In case of densely populated cities (e.g., New …

Safety Investigation of Crash Rates During Hurricane Evacuations
<p>This study aimed to investigate crash rates across four distinct periods—evacuation, re-entry, emergency, and non-emergency—during Hurricanes Matthew (2016), Irma (2017), and Michael (2018). A notable gap in existing research pertains to understanding crash rates during these critical phases of …

Decision making model of behaviour in office building fire evacuations
… model of decision making in office building fire evacuations. Data was collected by means of a questionnaire and short film. The questionnaire contained separate fire scenarios that corresponded to the order of cue presentation in the film. For each fire scenario, participants in the study …

Analysis and Evaluation of Household Pick-up and Gathering Behavior in No-Notice Evacuations
… performance. To facilitate the chain-based evacuations, a relocation model is proposed by moving carless dependents of facilities (such as schools and daycare centers) to more accessible locations for pickup; a linear integer program is presented to determine optimal sites. The optimization …

Temporal-Spatial Analysis of Emergency Evacuation Traffic
<p>Mass evacuations, particularly those at a statewide level, represent the largest single-event traffic movements that exist. These complex events can last several days, cover thousands of miles of roadway, and include hundreds of thousands of people and vehicles. Often, they are also marked by …

Illness and injury in the offshore workforce.
… examined using data collected from 1,538 medical evacuations over a two year period from the offshore installations of ten major offshore operating companies. A questionnaire was developed for this purpose as was a communications system to facilitate its completion by the offshore medics of the …

Evaluating the Impacts of Connected Vehicle Technology on Evacuation Efficiency
No-notice evacuations of metropolitan areas can place significant demands on transportation infrastructure. In preparation, emergency managers and transportation engineers study potential demands and many create evacuation traffic management plans. The findings from a St. Louis Metro East …

INSIDE THE REZ CROSS: AN ASSESSMENT OF HOSTING EVACUEES DURING A WILDFIRE DISASTER IN BEARDY’S & OKEMASIS FIRST NATION
Wildfires in northern Saskatchewan cause evacuations of Indigenous communities every year in summer. The summer of 2015 brought with it one of the most destructive and widespread wildfire season in Saskatchewan history, provoking massive evacuations of northern communities to shelters in urban …

Documenting the Impact of Lifeline Service Disruptions on Healthcare System Performance Following Earthquakes Since 2000: A Reconnaissance Report Analysis
… service impacts, overall functionality, and evacuations of area hospitals and healthcare systems. This research found that lifeline service disruptions can impact hospital and healthcare system functionality, and hospital and healthcare system evacuations occurred the majority of the time for …

The evaluation of the 90 second certification test and the analysis of human behaviour within aircraft evacuation modelling
… to burns and smoke inhalation due to sub optimal evacuations. If post-crash survivors can be evacuated quickly enough then the survival rate could be improved. This thesis will examine the influence of exit availability on the evacuation of narrow bodied aircraft during 90 second certification …

Integration of micro- and macroscopic models for pedestrian evacuation simulation
Simulation of pedestrian evacuations of smart buildings in emergency is a powerful tool for building analysis, dynamic evacuation planning and real-time response to the evolving state of evacuations. Macroscopic pedestrian models are low-complexity models that are and well suited to algorithmic …

Vertical transport evacuation modelling
… utilising such devices in actual buildings for evacuations is rare. Despite a select number of structures throughout the world allowing the use of vertical transport devices within evacuation scenarios, little is understood with regards to evacuation vertical transport strategies and to what …

Optimal Evacuation Plans for Network Flows over Time Considering Congestion
… delay, and ultimately save lives during regional evacuations. The primary focus of this research will concern short-notice evacuations, such as hurricane evacuations, conducted by automobiles. Additionally, this dissertation addresses some traffic flow and optimization deficiencies concerning the …

The Bomb on the Bayou: Nuclear Fear and Public Indifference in New Orleans, 1945 - 1966
… protect their citizens. Plans that included mass evacuations and shelters were put forth to protect the public and prepare for the seemingly inevitable war with the Soviet Union. These efforts faced tremendous obstacles, including a persistent sense of apathy amongst the public. Many authors …

Agent-based Modeling of Emergency Building Evacuation
… - usually one rectangular room - but not in evacuations of multi-room or multi-floor buildings. This implies that the effect of the complexity of building architecture on the collective behavior of the agents during evacuation has not been fully investigated. Here, we employ a system of …
