Abstract: In the paper the mathematical model of the evacuation processes from a chosen types of rooms in buildings, based on the Langevin equations, is presented. This process is an example of a collective dynamics of a set of self driven particles. In the equations additional term - social force - describing the interactions of the pedestrian with obstacles and other pedestrians, is included. As a result of numerical simulations the trajectories of each pedestrian in the room are found and the time of evacuation is calculated as a function of the desired velocity of pedestrians, which can be treated as the measure of the level of panic. Evacuation process can have laminar or turbulent character, depending on the geometry of the room and the number of persons present in it..
