- Abstract
- This research project is a joint study between fire safety researchers at the Institute for Research in Construction of the National Research Council of Canada (NRC) and the Societe de transport de la communaute urbaine de Montreal (STCUM). The objective of this project was to collect information on the passengers' use of the Butterfly Door for evacuation. To obtain a complete spectrum of information, it was decided to study the daily use of the Butterfly Door, its use with a large crowd of people and its use during two evacuation drills. The first study examined the daily use of the doors, measured by video cameras installed in three locations from the beginning of April to the beginning of May 1997. The second study examined the exit movement of a large crowd, during the annual International Benson & Hedges Fireworks. The third study consisted of two evacuation drills that were conducted at the Papineau Station.
