The process of evacuation from a classroom is investigated experimentally for three kinds of exit width and four kinds of internal layout. Spatial distribution of evacuation time is obtained to analyze evacuation efficiency. In case of double-desks, people tend to enter the nearest aisle. The arrangement of desks determines upstream flow from aisles and the exit width determines the flow capacity, both affecting the evacuation time. The evacuation time decreases with the increase of number of aisle, but not always so. For a classroom with a fixed width, more aisles are beneficial to evacuation. However, the reduced aisles width may cause conflicts between peoples from both sides. In case of small exit, congested area occurs at the exit and the evacuation time increases significantly. The evacuation process can be improved by controlling upstream flow and reducing conflicts among people.
