“…Once an emergency occurs (e.g., fires, chemical spills, environmental pollution, and natural disasters), evacuating all occupants safely and rapidly in buildings is a serious and central issue [19,20]. This emphasizes the importance of effective evacuation plans to minimize the number of casualties during emergencies [21]. Therefore, when designing new buildings and enforcing performance-based rules, it is crucial to understand the dynamics of human evacuation and population-based access to performance models to minimize the risk of occupants being exposed to critical conditions during a fire [22].…”

Most people use stairs during emergencies and evacuations. Therefore, this study addressed the impact of staircase rotation to minimize physical effort and evacuation time, hypothesizing that staircase rotation affects the evacuation speed and the safety of the occupants. This study consisted of two stages. In the first stage, a questionnaire was delivered to architects, with two key questions about the preferred direction in daily use and the other regarding evacuation cases. The second stage involved field experiments on two different staircases in the rotational direction, which were applied to 53 participants to measure the efficiency of the staircases in four cases (slow descent, slow ascent, fast descent and fast ascent). The counter-clockwise staircase during the field experiments showed better results and was more efficient. The heart pulse rate (pulse/min) in the clockwise case showed a clear increase compared to the counter-clockwise case by 12.89% for slow descending, 6.91% for fast descending, 21.51% for slow ascending, and 18.27% for fast ascending. Therefore, the theoretical and practical results of the study validated the hypothesis on the impact of the staircase rotation on user comfort and evacuation speed. Moreover, it was concluded that counter-clockwise staircases provided faster evacuation with less physical effort.

“…Many evacuation methods, such as network modeling [5], affordance-based finite state automata (FSA) modeling [6], cellular automaton models [7,8], lattice-gas models [9], 2 Discrete Dynamics in Nature and Society floor field models [10], and finer discrete models [11], have been proposed to study the characteristics of occupants' evacuation. These studies play important roles in predicting pedestrian behavior during evacuation and in designing evacuation facilities [12].…”

In order to analyze the evacuation capacity of parallel double running stairs, a dozen stairs merging forms are set by investigation and statistics, and the improved agent-based evacuation model that considers the merging behavior is used to simulate the process of merging and evacuation in the stairs. The stairs evacuation capacity is related to the evacuation time and the robustness of stairs, and the evacuation time can be calculated by using the improved agent-based model based on computer simulation. The robustness of each merging form can be obtained according to the fluctuation degree of evacuation time under the different pedestrian flow. The evaluation model of stairs evacuation capacity is established by fusing the evacuation time and the robustness of stairs. Combined with the specific example to calculate the evacuation capacity of each stairs form, it is found that every merging form has different evacuation time and different robustness, and the evacuation time has not positive correlation with the robustness for the same form stairs. Meanwhile, the evacuation capacity of stairs is not related to the number of the floor entrances. Finally, the results show that the evacuation capacity of stairs is optimal when the floor entrances are close to out stairs in parallel double running stairs and suitable to the case where pedestrian flow and the change of pedestrian flow are large.
