“…ird, it offers inaccurate results when individuals in a high-density crowd are forced into a fixed discrete cell, but large size of cells may cause a loss in computational efficiency. e social force model [13] presents pedestrian behaviors microscopically through social fields triggered by individual social behaviors, which enables researchers to explore new relations and mathematical rules of evacuee behaviors such as decision adaption. e majority of studies have investigated from an architectural optimization perspective [33,36] to improve evacuation process and pedestrian decision-making with the social force model.…”

“…Due to the actual growing complexity of the architectural designs, it is difficult for building codes to synchronize with building requirements. People have been adopting performance-based solutions to address complex design issues [12,13], and crowd evacuation simulation is viewed as an effective method to help engineers identify design shortcomings and improve building performance. Crowd modeling has emerged from a need for pedestrian simulation that adapts to technological development and challenges of laboratory experiments, and many simulations have been conducted to reproduce crowd behaviors at egress [14].…”

Exits are essential to the efficiency of building evacuation due to its irreplaceable function, and the layout of multiple exits has always been the key concern for architectural design. To accurately evaluate the evacuation efficiency of different multiexit layouts and optimize the design rules, a dynamic exit decision model integrating an exit selection strategy and the social force model is developed to simulate the practical evacuation. And our proposed model outperforms the original social force model in terms of evacuation efficiency. Accordingly, different layouts are analyzed for evacuation in a single room with two exits. The analysis results reveal that evacuation time will be improved with the changes of exit locations and two parallel exits are validated as the most efficient layout among the three common categories. Affected by walking time and queuing time of evacuees, it is not conducive to evacuation whether the separation of two exits is too large or too small. Furthermore, an even symmetry is found more efficient than an asymmetric distribution of exits under some conditions. This work provides a basis for architectural designs of multiple exits and a foundation for further study of evacuation simulation.

“…Alam and Habib [14] identified the most likely collision hotspots by the Bayesian theory, and encodes them with the micro simulation model of collision occurrence module in dynamic traffic, revealing that collision has a serious impact on evacuation. Facing the overlong and complex evacuation routes in large underground public space, Gao et al [15] introduced a constraint-based design model to automatically optimize the location of evacuation gates in buildings; Under space constraint and design constraint, the introduced model shortens the evacuation time by minimizing the length of the evacuation route. Li and Xu [16] proposed a safe evacuation model for confined space, which considers the differences in individual features and building factors.…”

In recent years, many cities have stepped up the development and use of underground public space. However, the development of underground space is constrained by safe evacuation. It is urgent to design a suitable safe evacuation model for ultradeep underground public space (UUPS). From the perspective of building design, this paper creates a novel safe evacuation model that integrates sunken shelter with a self-designed safe evacuation system (SES), and compares its effect with that of other models. Then, the application of our model in Hongtudi Station, Line 10 of Chongqing Rail Transit (CRT) was simulated on Pathfinder. The results show that the safe evacuation model, which couples sunken shelter with the SES, is feasible to evacuate personnel from the UUPS. The research sheds new light on the safe evacuation technique from the UUPS.

“…Furthermore, intense hysteria and stamping can contribute to multiple individuals evacuating in emergencies. The layout of escapes from structures, human psychology and behavior, and numerous social, behavioral patterns can profoundly impact evacuation performance, which leads to being trapped [3]. Thus, it is a need for a high-rise building to have an evacuation model to allow evacuees to exit the building without any harm safely.…”

This research aims to describe the adaptation of the Integrated Assessment Model (IAM) in modeling a conceptual framework for an intelligent indoor evacuation model assessment algorithm in a high-rise building. Evacuation defined as moving from a place that gives danger or threat to a safer place and evacuation model used to help evacuees to evacuate safely without any harm. Currently, many evacuation models developed, but each model focused on different evacuation behavior and time; hence the models differ in terms of its features. Moreover, the validation and comparison of each evacuation model have been made independently without using any standard assessment that encapsulates the functions involved in the critical incident during the indoor evacuation and virtual spatial element. Therefore, this proposed conceptual model believed to act as guidance in developing the assessment algorithm that needed for the evacuation models. It is essential to ensure that there is a standard guideline for the researchers to validate and compare with the existing evacuation model in a critical incident.
