Study on Evacuation Characteristics of Laboratory Personnel in University

To study the evacuation characteristics of laboratory personnel in university, the evacuation experiments were conducted under different layouts and scenes, that cross-combine three layouts forms and five scenes were carried out. Behavioral results were collected through several field experiments aimed at the door opening time, the personnel evacuation time with different layouts and evacuation ability. The results show that the evacuation ability of the evacuation door (0.9m wide) is about 120 persons/min when the evacuation door come into congestion, and the average of door opening time was 4 seconds. Meanwhile, a reasonable laboratory layout can reduce the evacuation time.
