The evacuation time of occupants from the building is one of the most important issues in fire safety design. Fire safety is designed in two ways, prescribed based on building codes and standards, and the performance basis is based on engineering judgment. In many special buildings, such as high-rise and complex buildings, the performance method is more applicable. Most performance-based methods require computer models that require cost and time. The purpose of this paper is to provide a simple analytical method that allows the study of evacuation by considering the speed of movement of occupants and the limitations of the capacity of the exit doors. One of the advantages of this method is that it considers simple algebraic equations of traffic at exit doors. To evaluate the accuracy of the method, this method has been compared with an approved computer model. The results show that this method can be used in designing escape routes for initial designs.
