“…Meanwhile, there are secondary risks when climbing over the gate for evacuees, e.g., tripped over the winged door, building collapsed, due to earthquake, etc. [1,4] Contrary to the criminological metaphor, the BWB under emergencies is not just about catastrophic consequences. A mild or radical breaker may lead to different evacuation results.…”

“…The transport infrastructure in congested regions often presents a vulnerability under natural disasters, such as an earthquake, fire, hurricane, etc. As a common, but serious, natural disaster, earthquakes principally result in shaking, ground rupture, structure collapse, etc., and destroy the stability of transport systems [1]. Many incidents with serious consequences occurred near extremely crowded areas, such as exits.…”

The automatic flap barrier gate system (AFBGS) plays a critical role in building security, but it is more vulnerable to natural hazards than common exits (including power failure, due to earthquakes, and delayed evacuation, due to safety certification, etc.). This article considers a dynamic decision-making process of evacuees during post-earthquake evacuation near an AFBGS. An interesting metaphor, broken windows (BW), is utilized to interpret people’s actual behavior during evacuation. A multi-stage decision-making mechanism of evacuees is developed to characterize the instantaneous transition among three defined stages: Habitual, mild, and radical states. Then, we build a modified three-layer social force model to reproduce the interaction between evacuees based on an actual post-earthquake evacuation. The simulations reveal that BW provides a contextualized understanding of emergency evacuation with a similar effect to the traditional metaphor. An earlier appearance of a mild rule breaker leads to a higher crowd evacuation efficiency. If evacuees maintain the state of broken windows behavior (BWB), the crowd evacuation efficiency can be improved significantly. Contrary to the criminological interpretation, the overall effect of mild BWB is positive, but the radical BWB is encouraged under the command of guiders.

“…In observing the impact of familiarity of the place and habitual preference, the simulation results of Song et al [24] showed that people with better knowledge usually have higher evacuation efficiency. However, this may not be the case in an earthquake context where logical thinking of an individual significantly decreases.…”

Preparing for an unprecedented event involving the movement of populations could take up large amounts of resources if done conventionally. The main motivation of this study is the behavioural modification approach which is an underexplored potential in evacuation dynamics, offering new possibilities in terms of practicality and ease of implementation. This paper tackles an adaptive building evacuation simulation and decision support framework that will serve as a guide to evaluate and propose evacuation strategies for disaster management researchers and decision-making authorities. The framework mainly involves the formulation of the cognitive agent model, the evacuation simulation, and the decision support. The timeliness in the Philippine context of the long-overdue "Big One" earthquake, the vulnerability of the case study, and the capability of the framework to be a standard guide where components can be customized by users based on the disaster type and site-specific requirements make this research a significant undertaking.

The benefits of evacuation drills for disaster preparedness are not yet well-established. Virtual reality and serious games (SG) application to evacuation simulation were proven to be effective in overcoming limitations of traditional emergency training approaches with a significant increase in the trainees' knowledge and self-efficacy. Further, human behavioural modelling is a critical component of evacuation simulation.The succeeding version of the implementation will apply the results of the survey on the agent model and perform the simulations on the four identified crucial scenarios.
