“…It could be because people who receive higher education are easier to deal with, receive or feel interested in disaster response knowledge. Huang [2] study showed that older participants are shown to be more efficient in evacuating the population, such as being able to get out quicker. Method In January 2023, we carried out a survey of the Jakarta and its surrounding areas.…”

“…In today's modern cities, high-rise buildings have become a symbol of high modernisation, and they are usually considered to be representative landscapes. However, with large-scale crowds, multiple floors and limited evacuation channels, the emergency evacuation from high-rise buildings is a huge problem especially when earthquake occur, which may cause lots of casualties [2]. Increased concentrations of people in crowded areas such as high-rise buildings pose increased risks to human lives.…”

The earthquake that occurred in Cianjur Regency on December 21, 2022 had a wide impact on the city of Jakarta and its surroundings. The shocks caused by the Cianjur earthquake were also felt by workers who were in high-rise buildings in the city of Jakarta and its surroundings. Evacuating employees in high-rise buildings has its own challenges, employee knowledge in earthquake evacuation is an interesting thing to study. This study aims to examine the level of knowledge of employees in earthquake evacuation and the factors that influence it. The survey was conducted on 79 worker respondents who have offices in high-rise buildings in Jakarta and its surroundings. The sampling was done randomly. Data collection was carried out using a questionnaire designed to measure the variables of knowledge, experience and training. The results showed that 63.3% of the respondents had never experienced a destructive earthquake, 30.4% rarely experienced a destructive earthquake, and 6.3% often experienced a destructive earthquake. Respondents had never participated in earthquake preparedness training 34.2%, 50.6% rarely attended, and 15,2% often attended earthquake preparedness training. Respondents’ level of knowledge in earthquake preparedness was 91.1% in the high category and 8,9% in the moderate category. Training has a significant effect on earthquake preparedness knowledge.

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.

“…Fang's research ( 18 ) demonstrated that the downward velocity is determined by three aspects: merging behavior in the entrance buffer of the stairwell, the strength of participants, and visibility in the stairwell. In its evacuation experiments on super high-rise buildings, it is proved that compared with males, females are more sensitive to changes in vertical evacuation height ( 19 ), and the travel distance will affect descent speed ( 20 ). Model studies on evacuation efficiency show that human behaviors, including the arrival rate at the floor exit the decision-making on refuge floors, play an important role in affecting the evacuation efficiency ( 21 ); the evacuation time of 1,050 pedestrians under the situation of fatigue is almost twice of that under the situation of constant speed ( 22 ); evasive behavior between heterogeneous pedestrians ( 23 ) and physical isolation facilities ( 24 ) can reduce evacuation time.…”

Large-scale public buildings (e.g., stadiums and comprehensive hospitals) in modern cities provide places for various social activities. However, all of these public places encounter the scenario of large passenger flow and crowd gathering, which is highly likely to induce serious safety problems, such as stampedes. Previous studies have shown that efficient evacuation is an important way to ensure the safety of dense crowds in public places. This study aims to explore the optimization methods to improve the evacuation efficiency of public buildings. Two strategies considering plane partition and multi-floor layout are proposed for plane evacuation and vertical evacuation, respectively. Simulation scenarios and models of large stadiums and high-rise hospitals are established to verify the strategies. The results show that plane partition could effectively shorten the total evacuation time, which is due to the optimization of the initial exit choice of individuals and the avoidance of regional congestion in some evacuation channels or exits. Multi-floor layout optimization is an effective management method to arrange the different features of different floors, which could improve the evacuation efficiency for the whole multi-floor building. This study is helpful for building designers and managers to improve the building space layout design and the daily safety management mode.
