Abstract

When evacuating a high-rise building, two streams of evacuees meet at the landings: those who are already descending the stairs and those who are about to enter the staircase through the landing door. In this article, merging of these streams is studied with calculations and with queuing and agent-based simulation models. The agent model considers in detail the interactions between the agents and between the agents and the building. The queuing model has two queues which merge together for each floor of the building. The process is defined by a merge ratio. The merge ratio or priority of one queue does not have an effect on the total egress time, but it affects floor-wise waiting times and journey times. The results show that evacuation of the highest floors of a tall building is not accelerated substantially, because possibilities of adjusting the merge ration are limited.
