“…The emotional matter for each agent is obtained by summing up these panic emotion elements. In (2) shows the degree of danger in invoking panic emotion in a certain agent, where the panic value of agent i is denoted as E h i (P, t). It is influenced by all hazards s with a total number of n at a certain position p at time t.…”

Crowd evacuation can be a challenging task, especially in emergency situations involving dynamically moving hazards. Effective obstacle avoidance is crucial for successful crowd evacuation, particularly in scenarios involving dynamic hazards such as natural or man-made disasters. In this paper, we propose a novel application of the emotional reciprocal velocity obstacles (ERVO) method for obstacle avoidance in dynamic hazard scenarios. ERVO is an established method that incorporates agent emotions and obstacle avoidance to produce more efficient and effective crowd navigation. Our approach improves on previous research by using ERVO to model the perceptive danger posed by dynamic hazards in real-time, which is crucial for rapid response in emergency situations. We conducted experiments to evaluate our approach and compared our results with other velocity obstacle methods. Our findings demonstrate that our approach is able to improve agent coordination, reduce congestion, and produce superior avoidance behavior. Our study shows that incorporating emotional reciprocity into obstacle avoidance can enhance crowd behavior in dynamic hazard scenarios.

The spatial layout and arrangement of obstacles in the built environment significantly affect its evacuation performance. However, few researchers focus on pedestrian simulation-based design optimization of built environment under emergency evacuation conditions. In this paper, we aim to evaluate the evacuation performance of optimized design solutions for traffic space in the teaching building of a primary school based on a pedestrian simulation approach and to quantify the effect of design parameters on evacuation time. Firstly, the level of traffic space design parameters was determined and optimized design solutions for the traffic space of the school building were generated. Secondly, based on the Anylogic simulation platform, the environment module and pedestrian evacuation behaviour rules of the teaching building were built to realize the evacuation behaviour simulation. Thirdly, the effect of the traffic space design parameters on the evacuation time of the teaching building was evaluated and the most significant design parameters were identified. Finally, the optimal combination of traffic space design parameters was proposed under evacuation performance orientation. The results show that the sensitivity of the traffic space design parameters to evacuation time is 31.85%. The effect of corridor width on evacuation time is 49.06 times greater than the staircase width. The optimal design combination for the traffic space in the teaching building of the primary school is a 3.0 m wide trapezoidal corridor combined with a 3.6 m wide staircase, and a 3.0 m wide fish maw corridor combined with 3.6 m wide staircase, guided by evacuation performance. The framework developed in this paper provides technical support for the development of evacuation performance-oriented design optimization of the built environment, and the results are intended to supplement the building design specifications.

“…Evacuation routes are routes specially provided to connect rooms or buildings to safe areas in the event of a fire. In the event of a disaster, to reduce loss of life and loss of property, people who are in or near the building need to be evacuated to a safe place, namely a gathering point (Gao et al, 2023). Evacuation route signs and emergency exit signs are used in buildings to guide occupants to a safe place and away from danger in the event of a fire (Filippidis et al, 2021).…”

The Occupational Safety and Health Administration (OSHA) indicates that academic laboratories are 11 times more dangerous than the industrial sectors. The nutrition laboratory is a place that has a high potential to cause fire because there are cooking activities, where these activities are very risky because they deal directly with fire and gas cylinders there. If the gas cylinder has a leak, it can cause a fire risk. This study aims to look at the preparedness of fire disaster management in the Nutrition Laboratory at University X in Semarang city. The research design used in this research was a descriptive qualitative. There were 3 informants, namely the person in charge of the nutrition laboratory and 2 students of the Nutrition Study Program. Data collection techniques used in this research was in-depth interviews. The results showed that the nutrition laboratory at University X in Semarang city already had management related to fire prevention such as the availability of fire extinguishers, evacuation routes, and assembly points. It is recommended that related parties complete active and passive protection systems, improve fire prevention teams, train and socialize, and conduct regular testing of active protection facilities in the Nutrition Laboratory.
