Hybrid epidemic simulation framework coupling equation-based and individual-based models
Jaeyoung Kwak, Michael H. Lees, Chin Chun Ooi +1
Mass gathering events like concerts, sports matches, and festivals bring many people into close contact within a short period, creating localized bursts of infection that can shape…
CompARE: A Computational framework for Airborne Respiratory disease Evaluation integrating flow physics and human behavior
Fong Yew Leong, Jaeyoung Kwak, Zhengwei Ge +7
The risk of indoor airborne transmission among co-located individuals is generally non-uniform, which remains a critical challenge for public health modelling. Thus, we present Com…
Characterization of pedestrian contact interaction trajectories
Jaeyoung Kwak, Michael H. Lees, Wentong Cai
A spreading process can be observed when a particular behavior, substance, or disease spreads through a population over time in social and biological systems. It is widely believed…
Characterizing pedestrian contact interaction trajectories to understand spreading risk in human crowds
Jaeyoung Kwak, Michael H. Lees, Wentong Cai
A spreading process can be observed when particular information, substances, or diseases spread through a population over time in social and biological systems. It is widely believ…
Influence of committed volunteers on helping behavior in emergency evacuations
Jaeyoung Kwak, Michael H. Lees, Wentong Cai +2
We study how the presence of committed volunteers influences the collective helping behavior in emergency evacuation scenarios. In this study, committed volunteers do not change th…
Modeling Helping Behavior in Emergency Evacuations Using Volunteer's Dilemma Game
Jaeyoung Kwak, Michael H Lees, Wentong Cai +1
People often help others who are in trouble, especially in emergency evacuation situations. For instance, during the 2005 London bombings, it was reported that evacuees helped inju…
Estimating horizontal movement performance of patient beds and the impact on emergency evacuation time
Jaeyoung Kwak, Michael H. Lees, Wentong Cai +2
Emergency evacuation of patients from a hospital can be challenging in the event of a fire. Most emergency evacuation studies are based on the assumption that pedestrians are ambul…
Collective patterns of pedestrians interacting with attractions
Jaeyoung Kwak
Walking is a fundamental activity of human life, not only for moving between places but also for interacting with surrounding environments. While walking to destinations, pedestria…
Jamming transitions induced by an attraction in pedestrian flow
Jaeyoung Kwak, Hang-Hyun Jo, Tapio Luttinen +1
We numerically study jamming transitions in pedestrian flow interacting with an attraction, mostly based on the social force model for pedestrians who can join the attraction. We f…
Impact of Impulse Stops on Pedestrian Flow
Jaeyoung Kwak, Hang-Hyun Jo, Tapio Luttinen +1
We numerically study the impact of impulse stops on pedestrian flow for a straight corridor with multiple attractions. The impulse stop is simulated by the switching behavior model…
Effects of switching behavior for the attraction on pedestrian dynamics
Jaeyoung Kwak, Hang-Hyun Jo, Tapio Luttinen +1
Walking is a fundamental activity of our daily life not only for moving to other places but also for interacting with surrounding environment. While walking on the streets, pedestr…
Collective dynamics of pedestrians interacting with attractions
Jaeyoung Kwak, Hang-Hyun Jo, Tapio Luttinen +1
In order to investigate collective effects of interactions between pedestrians and attractions, this study extends the social force model. Such interactions lead pedestrians to for…
