Mapping knowledge structure and research trends of emergency evacuation studies

Safety Science, 2020
To understand the current development and status of research on emergency evacuation, the published literature in the Web of Science core database from 2008 to 2018 were taken as the research objects, and the knowledge structure and research trends in ...

Investigating the influence of route turning angle on compliance behaviors and evacuation performance in a virtual-reality-based experiment

Advanced Engineering Informatics, 2021
Route turning is one of the most essential and ubiquitous physical features in the complex building environment. Under the influence of route turning, evacuees’ approaching perspective to an emergency sign could vary, affecting their information ...

Modelling and interpreting pre-evacuation decision-making using machine learning

Automation in Construction, 2020
The behaviour of building occupants in the first stage of an evacuation can dramatically impact the time required to evacuate buildings. This behaviour has been widely investigated by scholars with a macroscopic approach fitting random distributions to ...

Emergency evacuation risk assessment and mitigation strategy for a toxic gas leak in an underground space: The case of a subway station in Guangzhou, China

, 2021
In emergency system design, evacuating people from dangerous buildings has always been a significant yet challenging undertaking. This paper combines evacuation demand analysis with a toxic gas dispersion process to create an underground space risk ...

Why do people make risky decisions during a fire evacuation? Study on the effect of smoke level, individual risk preference, and neighbor behavior

, 2021
People make risky decisions during fire evacuations such as moving through smoke. However, the reasons behind such risk-taking decisions have not been investigated in controlled experiments.

A review of cellular automata models for crowd evacuation

Physica A: Statistical Mechanics and its Applications, 2019
With the increasing of risk potential in crowded places, evacuation management becomes practically important to ensure the safety of crowds. The studies of crowd evacuation in normal or emergency situations have become a hot topic.

State-of-the-Art Pedestrian and Evacuation Dynamics

IEEE transactions on intelligent transportation systems (Print), 2020
This paper provides a critical review on the state-of-the-art pedestrian and evacuation dynamics so as to comprehensively comprehend the motion behaviors of pedestrians from observations to simulation aspects.

How the completeness of spatial knowledge influences the evacuation behavior of passengers in metro stations: A VR-based experimental study

, 2020
Emergency evacuation in metro stations could be highly challenging due to complex underground environments, dynamic hazards and high-density crowds. There are different types of metro passengers, such as first-time visitors and daily commuters, who may ...

Evacuation behaviour of crowds under high and low levels of urgency: Experiments of reaction time, exit choice and exit-choice adaptation

, 2020
How does evacuation behaviour of crowds vary based on the level of perceived urgency? This question was investigated using two simulated experiments of crowd evacuations, collectively exploring three important aspects of evacuees’ decision-making ...

Determining optimum staged-evacuation schedule considering total evacuation time, congestion severity and fire threats

Safety Science, 2021
For many years, simultaneous evacuation of the entire facility was a common approach. The deficiencies of this approach were revealed after many cases of casualties and evacuation efficiency drop that were observed during some evacuations caused by crowd
