The Itaewon disaster revealed the fundamental weakness of the modern disaster management system. Although surveillance technology and density-based monitoring systems have been introduced everywhere, there are still fatal loopholes in safely managing large crowds. Existing research has been conducted under the premise of a uniform crowd with the same adult, that is, everyone behaves similarly. This method improves the simplicity of management, but in reality, it does not properly reflect the reality that each individuals characteristics are complex and affect collective dynamics in a high-density environment.
Most of these studies do not reflect safety vulnerable groups such as the elderly, children, and the disabled. Safety vulnerable groups are exposed to risks due to complex limitations in crowded situations. As it has such various vulnerabilities, it greatly reduces the accuracy of disaster prediction. A disaster management system that does not receive fair protection results in deepening disaster inequality in crisis situations.
Existing studies have focused on crowd density. Individual diversity has often been put on the back burner. As a result, studies so far have been close to follow-up after a problem occurs. In this paper, a study is needed on how to organize the crowd and how the risks vary depending on these configurations.
These changes go beyond simple technological innovation and lead to ethical discussions that take a new look at crowd safety from the perspective of distribution justice. Based on this, a preemptive AI-based framework based on the disaster justice principle that values fairness and inclusion is being proposed. The system combines computer vision classification model and digital twin simulation environment to identify vulnerable groups in real time and calculate the Safety Vulnerable Class Weighted Risk Index (V-CRI), thereby evaluating their impact on the overall risk.
By making the composition of the crowd itself an important variable, this approach allows a transition from the existing post-response and density-centered method to a preemptive system. Those in urgent need of protection before an incident can be protected first.
