DESCRIPTION:Prof. Winnie Daamen\, Delft University of Technology\, The Net
 herlands\nEmergency doors may be bottlenecks in the evacuation of a buildi
 ng. As neither the capacities of these doors are not known\, nor details o
 n the behaviour of people near these doors\, large scale laboratory experi
 ments have been performed. Using video images\, we have identified the rel
 ation between the capacity and a number of factors\, such as door width\, 
 population composition and stress level. In addition\, the collected traje
 ctory data have been used to calibrate our pedestrian simulation model Nom
 ad and to compare the resulting behavioural parameters between evacuation 
 conditions and normal conditions. To do this\, an automated calibration pr
 ocedure has been developed\, which yields parameter estimates for individu
 al pedestrians. The existing calibration procedure has been extended by in
 cluding data from multiple pedestrians into a single estimate. The resulti
 ng parameter distributions provide insight into pedestrian behaviour. So f
 ar\, dedicated parameter sets have been estimated for elderly\, adults and
  children. It could be shown that not only the pedestrian behaviour change
 d between normal and evacuation conditions\, but also between the differen
 t types of persons.
