摘要：The article studies the dependence of the human flow density on two main parameters: the width of the staircase and the number of people on the floor. It was established that violation of standards in terms of the entrance door width and the presence of a stair hall have a strong influence on the total time of evacuation due to the formation of clusters. The tabular dependence of the maximum human flow density on the staircase width on the number of people per floor was obtained. On the basis of this dependence, the graph was built, which can be used in the stair width design, taking into account the allowable human flows density in the case of known average number of people on each floor of the building.
