ABSTRACT
The large number of persons, long evacuation distance, as well as the impact of the special circumstances of fire often lead to a phenomenon such as blind conformity, the bottleneck at the crowded stampede, and even wrong evacuation routes during the high-rise buildings’ evacuation. So a high-level scientific evacuation plan is extremely necessary. The existing evacuation model and common business evacuation software such as pathfinder and EVACENT mostly belong to the ‘pre-model’, setting a critical floor before simulations, that is, people below it use stairs to evacuate and the others use elevators, and repeatedly change the floor in order to ultimately obtain an approximate optimal floor that ensures that the overall evacuation time is the shortest, which greatly reduces the computational efficiency. Considering the limitations of commercial software in evacuation simulation, in our previous work, the stairs and elevators’ collaborative evacuation model was developed to quickly generate the optimal evacuation routes through only one computation by using the two factors in collaboration. This article expands the stairs and elevators collaborative evacuation model to research the influence of different fire floors on the evacuation routes in high-rise buildings and then dynamically adjust the evacuation routes to ensure that the total evacuation time is minimum.
