Abstract

This paper provides an analysis of the evacuation of the World Trade Center towers culled from telephone and face-to-face interviews with survivors. The first investigation explored where occupants were located when each tower was attacked. Regression analysis explored the sources of variance in occupants' time to reach the stairwell, as well as stairwell evacuation time (how long the average occupant spent in the stairwells per floor). Finally, issues identified as contributing to either slowing or aiding the evacuation process were also explored.
