What factors influence the walking speed of an occupant? Is it just their physiology and crowd density? It seems it is more complicated than that (as most things are in fire science...). Dr John Gales of York University takes me on a journey through their extremally interesting research on anthropomorphic data and movement speeds, which they have been extensively carrying through the last years. You will learn why the crowd at a football match will have a different characteristic than one attending American football (handegg?). Why evacuation is quicker in torrential rain than in fire, and how stimuli may drive the walking speeds as well. And how a beer tent helped uncover that!

John has mentioned a lot of resources that may be of interest.
